EDC3, NuForce
What makes trusty all-rounders great to play is their combination of balance, weight, speed, and overall strength in every area. That’s exactly what we aimed for with the new EDC3. The EDC3 aims for: Audiophile quality in speed, sonic weight, tonal balance, and clarity. Everyday Carry quality in comfort, accessories, everyday usability, and high value.
Sound Matters All-rounders don’t optimize for one or two areas, but look for overall strength across the range of attributes.
When it comes to sound values, the typical mass market IEM pumps up the bass value and creates a big peak somewhere in the treble.
If it is a smoother transition, we call this tuning “V-shaped” because EQ with sliders looks like this (bass is on the left and treble to the right):
Some music recordings already contain overly boosted bass and sharp glare in the treble. A boosted bass + treble peak tuning usually adds too much and can be fatiguing to listen to over long periods of time.
The alternative is to tune something musical (enjoyable to listen to) but more neutral than the typical mass market IEM. (Bass, mids, and treble in balanced amounts.) Mids seem to get neglected in a lot of mainstream products. So that’s where we started. Then we added treble to give a sense of air, but without being too bright-sounding. Finally, the prototypes went around for bass feedback with a couple different dampers until we got the okay from our community test group.
Balanced armature drivers: One bigger bass driver + two on top for mids/treble

Dampers look like this:

The new EDC3 is a combination of 3 drivers per ear that each handle different sections of the sound, some crossovers to mix sound in the right amounts, and balanced armature technology for drivers that fit into the earpieces. There’s also a mechanical damper (or filter) that we used to tune the final balance. We hope that the Massdrop x NuForce EDC3 is the the well-rounded character that you will be enjoying late into the game…

It WOULD be cool if that could be done but it looks like the dampener is integrated into the shell before it's clamped together. A re-work would be necessary to have a replaceable dampener system. Any chance of something like this in the future Nuforce? There is something similar from a Japanese company made for some of the Audio Technica IEMs.
‘ The new EDC3 is a combination of 3 drivers per ear that each handle different sections of the sound‘
Is it a 3-way cross-over? In the Brent Butterworth review he said It’s a 2-way design, basically the two balanced armatures for mid-highs are wired in Parallel. Can someone confirm? It’s not very clear. Thanks.

Yes, those are the correct ones. A little tip: when they start to lose shape, flip the flanges inside out and they should return to normal shape after a while. When they stop doing that that means it's time for a fresh pair.
Thanks for the tips (haha!) :)
These things sounded good for the price, but the left side died on me 2 days after receiving them.
I am thinking about getting either these or the "Massdrop x MEE Audio Pinnacle PX IEMs", what would anyone recommend, they're both about the same price. I intend to use them for cycling to work and general day use. If anyone could voice their opinion on what are a better pair of IEM's it'd be much appreciated, Thanks in advance,
I picked up some Model 3s before I noticed this drop ( and they look like they have a very similar head, but more importantly, the have a very similar connector; I wonder if it's possible to swap connectors on this guy so these become wireless too?
Are these earbuds sweat resistant? I'm in the market for some new good quality work out headphones but don't want to ruin them.

Yes, I really want a shorter cable as I plan on using this with a portable Bluetooth receiver (FiiO BTR3) and the bundled cables are really long.
Well that depends on how you use it. For example I have the cable under my t-shirt, so I actually quite appreciate that it's longer, since I don't have a problem taking my phone from my pocket to a comfortable viewing height
Are there balanced cords available for these to use with my ak240
is it better than Tin Audio T2?
Weren't these $41 on black friday?
I think you are referring to the MEE audio Pinnacle P2.
I want to ask, is this product can be delivered to Malaysia?
will these ever stop being sold? ive been putting off buying a pair for a while and im just concerned about whether or not ill be able to buy them in the future
oh. and another thing, do they have a burn in time?
Where can I get replacement cables for these earphones? The mic cable failed since new.
I am getting undesired volume reduction with the mic cable. If the cellphone is held in hand while walking, or if the cellphone is sitting on a steady surface, then the volume does not reduce. However, when I carry my cellphone in my pocket with the earphone plugged, the volume reduces to zero within seconds as I am walking. I tested a few other earphones (etymotic hf3, Shure SE215 with mic cable, Thinksound TS02, KZ ZS5) with mic and they do not cause this issue. Is anyone else encountering this issue as well?
Anybody from Massdrop, can you please reply?
Just email them, they don't have time to go over every comment.
anyone wanna buy mine? steep discount, my new phone doesn't have headphone jack :( I used these once for about an hour on a short flight msg me on insta @jak5080
Hello, I've had these wonderful headphones for a couple of months now, mainly using them at the gym. During my last gym session the volume on the left earbud dropped significantly, up to the point that if I have both plugged in, it feels as if only the right side works (but if i listen closely with only the left side plugged in, I can hear ir faintly). How can I troubleshoot this problem? I am using the braided cable and the large foam tips.

Swapped, didn't work. Dried them out in rice for a night and they returned to normal. Still disappointing as they are marketed as headphones you can take to the gym,but w/e. That being said, I would buy a Bluetooth IPX6+ version of these in a heartbeat.
Had the very same problem. When I posted about this a rep on the board here told me don't take them anywhere near water, so the gym for a good workout is out of the question. I will stick with my SE215 for the gym - they have been real troopers.
Hey guys, i received my EDC3s a couple months back and actually have been pretty happy with them ever since. I have not had any problems with them, but i recently noticed that they sound very slightly different than they used to. I also noticed some wax build up. How would you recommend cleaning them or should i even try to clean them? I have not touched the inner part of the tube yet since i am a bit concerned about damaging the mesh...

Intro Disclaimer: The EDC3 were sent to me free of charge by Massdrop in exchange for an honest review. I will keep the review as fair and unbiased as possible. Thanks Christian! Also, this review is quite long as I may have gotten a little carried away when typing it up. Sorry, not sorry. I am actually sorry for any weird formatting issues you may come across as this is essentially a copy-paste from Reddit, where I originally wrote this review.

My Preferences: I generally prefer a flat/neutral frequency response with a bit of extra energy in the upper midrange and sub bass regions. I generally dislike any sort of midrange recession. The response of the Etymotic ER4XR, 64 Audio A12t, and Focal Utopia are good references for the kind of sound signature I like. An HD700 with Sonarworks True-Fi active is generally my reference for a neutral sound.

TL;DR: These are now my go-to recommendation for a neutral IEM at the $100 price point. They have an excellent, somewhat mid-centric sound and good accessories.
The Non-Sound Stuff Packaging/Unboxing: The packaging has a nice, clean look to it. Inside the outer box are the IEMs and the carry case. With the exception of the medium silicone tips and audio-only cable which are pre-installed, all the accessories are inside the case. Overall, the packaging is very minimal which is fine for an IEM at this price point.

Accessories: I would consider the accessories that are included with the EDC3 to be above average; especially at this price point . They come with two cables (one has a mic), 3 pairs of silicone ear tips (S, M, L), 2 pairs of foam ear tips (M, L), a shirt clip, and a carry case.
The audio-only cable that comes pre-installed on the EDC3 is excellent. It exhibits very low levels of microphonics, is very supple, does not retain its shape, and is tightly wound. On the amp-end, it is terminated in a right-angle 3.5mm jack that feels sturdy enough. I generally prefer a straight plug but I can't knock it for that because I know that's a preference thing. The IEM side is terminated in a standard 2-pin configuration. This is the only IEM near this price point that I can think of that uses a 2-pin connection. That is excellent news for anyone who likes to use aftermarket cables. Overall, this is one of the nicest stock cables I've come across on an IEM in (or anywhere near) this price range. The silicone tips feel pretty cheap. I'm not a fan of them. They are quite firm and have noticeable seams on the sides. While I could get a good seal with them and could not feel the seams once they were in my ears, they were generally uncomfortable because of how stiff they were. I quickly switched them out for some Spin Fits which greatly improved the fit and comfort. The EDC3 have a narrow nozzle - like offerings from Shure or Westone. Keep that in mind when you're tip rolling. The case is very nice. I love the look and semi-hard design. It should do a great job at keeping the IEMs safe while not in use. My only minor nitpick with the case is that I wish it was round or more of a square. The rectangular design means once the cable is coiled for storage, two sides are going to more squished instead of retaining the round, coiled shape. Again, this is a very small nitpick. The EDC3's case is much nicer than the ones that come with the Hifiman RE600v2 or Shure SE-215; both of which come in at the same price point. I will do more in depth comparisons with those below.
Build Quality: The housings are made of plastic but feel pretty robust. The only seam-line on the housing matches up very nicely and isn't noticeable unless you're looking for it. The cable and case also feel high quality. I have no doubts these will hold up just fine to daily wear-and-tear and travel.

Comfort/Fit: Comfort was just okay when I was using the stock silicone tips. As I said above, I quickly switched over to Spin Fit tips and comfort improved. With the Spin Fit tips, comfort is very good. I can easily have them in for a couple hours at a time. Besides the pressure created by the tips, they completely disappear once they're in.The stock, audio-only cable weighs next to nothing and they feel very light overall. I don't like memory wires or molded cables on the IEM-side of cables but the molded heat-shrink wrap on the stock cable is very well done and I don't have any complaints.
Between the light weight, cable, and fit, they are very secure in my ears. They easily stay in during a run.

Sound Equipment Used: I used two different DAC/amps in my listening sessions: an iFi iDSD micro BL and a Soekris dac1541. Source music from Tidal.

First Impressions: When I first put them in, I was not impressed. They sounded veiled and vocals sounded a little unnatural. I figured I'd set them down for a couple hours and get back to them later that evening. If you're a little disappointed at first, set them down for a couple hours and then go back to them.

Bass: (3.5/5) The first thing I noticed with the bass is how well it extends for a triple BA IEM. It goes down to ~30Hz. That being said, the sub bass impact sounds rather weak. I would describe the bass as neutral with a slight roll-off at the very low end. I would describe it as typical BA bass in that it can hit the low notes but it does not have the natural decay or impact of that of a good dynamic driver. The bass feels very fast; almost a little too fast in terms of decay. This is something that most BA IEMs struggle with. Listening to beat-centric songs or songs with strong bass lines is a bit boring. While a lot of this is just the neutral sound signature, some of it comes down to how natural the bass sounds. If the bass produced by dynamic drivers sounds natural to you, then this IEM may not suit you. Also, if you prefer a bass quantity above neutral, the EDC3 is not for you.I tried using the bass boost on the iDSD BL and got poor results; the bass increased a little but not nearly as much as I would normally expect. The bass seemed to lose a little definition when using the bass boost which is something I've never experienced from the iDSD before. It seems as though the bass driver(s) in the EDC3 are not able to efficiently produce much more bass than they're tuned to. I have not tried EQ but I assume the outcome would be similar.

Midrange: (4.5/5) The midrange is the star of the show here. The midrange is almost dead flat with just a slight hint of warmth to it. The midrange is clear and instruments sound very natural. Most vocals sound very nice as well. Some female vocals can sound a little veiled due to what I perceive as a dip in the upper midrange that hits its trough in the middle of the presence region (low treble). This is why I felt they were veiled in my first impressions. This is also probably why I hear them to be slightly warm. If the presence region was brought up a little, I'm sure I'd hear them as completely neutral. One of the songs where I really noticed this dip was The Other Side by Tonight Alive. What's weird is that I didn't really notice it as much with other songs by Tonight Alive. Because of the dip, vocals sound like they're back as a part of the music, rather than front and center where I normally expect them to be.

Treble: (4/5) Following the dip in the presence region, the treble response sounds fairly smooth up to ~13kHz. There is a peak around 10kHz but it is small and does not create any sibilance. After 13kHz it seems to fall off quite a bit. It does go up to where I can't hear around 17kHz but after 13kHz it's pretty quiet. I would like a bit more extension into this high region. The treble sounds like it's a little held back, just below neutral. While these don't quite have enough quantity or extension for my taste, what the treble does do is provide a very smooth and completely inoffensive presentation. It makes the EDC3 a very comfortable IEM to listen to for long periods.

Soundstage/Imaging: Soundstage is about average in width for an IEM; all of the sound is produced between my ears. Nothing sounds like it's coming from outside my head. Imaging is very good in that I can pick out instrument locations in that soundstage quite easily. The soundstage has much more height and depth than most other IEMs I've heard. It's almost like the inside of my head is a concert hall and the entire thing is being filled with sound: front to back and top to bottom. Most IEMs produce sound between my ears and it sounds like everything comes from a narrow band in that area. I guess it's kind of hard to explain.
Detail Retrieval/Other: The EDC3 are about average in terms of overall detail at this price point. There is a good amount of separation between instruments and they never sound congested. Isolation is good, but not great. It's not as good as I'd normally expect from an all-BA IEM. It looks like there's a bass port in the housing, on the ear-side, near the cable connection. I suspect this is the reason for the lower-than-expected isolation. Still, they should isolate well enough for a daily commute on public transportation. I never use public transportation so it's hard for me to say for sure. For example, they isolate a lot better than my FLC 8S which I have used on a subway before and I was fine with those.
Comparisons Shure SE215 ($99): The SE215 are much bassier and have a warmer sound overall. In comparison, the SE215 sound a more congested and don't have the same sense of naturalness in the midrange that the EDC3 have. The treble on the SE215 is a bit more recessed and doesn't sound quite as accurate. The accessories that come with the EDC3 are nicer. The EDC3's cables feel higher quality and I would consider the 2-pin connection a step up from the SE215's MMCX. The EDC3's (semi) hard case will actually protect them instead of the soft case the SE215 come with that allow the IEMs to be crushed. Build quality (longevity) is similar but I think I'll have to give it to the EDC3 because the housings feel just a little bit nicer and it comes with a second cable. As I said above, the EDC3 case offers better protection and if you use it, it should keep them from being damaged - even if thrown under other objects in a backpack. I find the EDC3 to be much more comfortable with a better fit. I use the same exact Spin Fit tips on the SE215 and I find that it's harder to get a seal with them. The SE215 housings don't fit my ears as well as the EDC3 and I notice a bit of discomfort after about 15-30 minutes of use. For me, the EDC3 win this in every way. However, if you prefer a bass-heavy signature to a neutral one, the SE215 are more likely to please you.

HifiMan RE600S Songbird V2 ($99): The two of these IEMs actually sound somewhat similar. Bass response is about the same in terms of quantity but the quality is a little better on the RE600S. The RE600S's dynamic driver produces a more natural sounding bass response and has better sub bass impact. The midrange on the RE600S sounds a bit cooler. I would say it is slightly cool of neutral about the same amount that the EDC3 is slightly warm of neutral. The treble is where the biggest difference occurs. The RE600S comes off as a little brighter and takes more of your focus than on the EDC3. IMO, the bass and treble are better on the RE600S while the EDC3 has a better, more natural sounding midrange. I'd say sound quality is about the same on both. Soundstage is similar but the RE600S doesn't have as much height or depth to the sound. Overall detail is about the same but the RE600S sounds like it beats the EDC3. I think this is because the treble takes more of your focus. Generally speaking, people perceive more treble as more detail. Build quality is far better on the EDC3. The fact that the EDC3 has removable cables is enough reason alone to buy it over the RE600S. The EDC3's cables are much nicer.The RE600S is more comfortable than the EDC3. The housings are even smaller and lighter with the added bonus that they can be worn over or under the ear. The biggest reason I find the RE600S more comfortable is that I can use my normal UE (900S) silicon tips on it. Those tips fit me better than the Spin Fit tips. The stock tips that come with the RE600S are higher quality than the ones that come with the EDC3. The only thing the RE600S does substantially better is the packaging and unboxing experience. While this is a very minor thing, opening the RE600S is an experience and the leather-bound box makes you feel like you're opening something special. Still, it's not a reason to buy it over the EDC3. This matchup is much closer, with overall sound quality being about the same. However, the difference in build quality and the removable cables make the EDC3 the clear winner.
Other: I no longer own the 1More Triple Driver ($95) but I did just hear them again recently at CanJam RMAF. I prefer the sound signature on the Triple Driver to the EDC3 for a bit of fun but the overall fit, comfort, and isolation are better on the EDC3. Even though the materials used on the Triple Driver feel nicer, I think the build quality is better on the EDC3. I've seen too many people post about their Triple Driver falling apart to trust they'll last a long time. It's been awhile since I've heard them, but I prefer the EDC3 to the Dunu Titan 3 ($99) and Titan 5 ($132). I was not a big fan of the sound on the Titans. The EDC3 is better in every way except potentially build quality. The metal construction on the Titan 3 and Titan 5 make them feel very robust.
Conclusion If you're in the market for a neutral IEM around $100, look no further. The EDC3 is an IEM that isn't the best at any one thing but does everything well. It is the most well-rounded IEM less than $300 I've had the pleasure to own in terms of sound, comfort, build, and accessories. Massdrop hit the mark in looking to make a great Every Day Carry IEM.The midrange is the best part of the sound and even that isn't perfect IMO. It could use a little more energy in the upper midrange and presence region. The dip in that region can make some vocals sound a little veiled but I don't notice it most of the time. What's odd is that I don't fully love any one part of the sound but when I put them in, I don't want to stop listening to them. I stayed up too late 2 nights this week just because I wanted an extra hour to listen to them. They have a very relaxed, sweet sound that is very pleasing and easy to listen to. They are not fatiguing in any way. The EDC3 are now my most-likely-to-recommend IEM at the $100 price point and, if you can, I highly urge you to give them a listen. Side note: For the number rankings, they are rated out of 5. 5/5 being the best sound quality I've heard in the $50-$100 category. Overall, I'd give them 4-4.5/5. Ergonomically they are excellent and they also sound very good. There are too many small issues with the sound and the bad stock silicone tips keep them from the 5/5 rating.
Song List Below are just a few of the MANY tracks I listened to with the EDC3: Snuff - Slipknot The Other Side, Without You - Tonight Alive Dreams - Fleetwood Mac Come On - Green River Ordinance Best Days - Graham Colton Tarova - Snarky Puppy Rack City - Tyga Superstition - Stevie Wonder Aliens (her er jeg) - Ina Wroldsen Mahna, Mahna - Cake Strobe - Deadmau5 I'm Comin' Over - Chris Young Your Shirt - Chelsea Cutler Nobody Compares to You - Griffin and Katie Pearlman Cool - Rachel Reinert I O U - You Me At Six God of War - Bear McCreary Bird on a Wire - Jennifer Warnes Not the American Average - Asking Alexandria Used to You - Dagny Keep Lying - Donna Missal
So... My EDC3s kicked the bucket today. They split in half. I've been part of the people of the original drop so it's been a while since I had these. This is a warning to you guys if you wanna buy these earbuds.
have bit of a concern/ question about the QC. on the nozzle, where the filter is inserted, it has made the nozzle bulge ever so slightly on the right side. you notice it when you put eartips on that side, since it gets a bit too tight. and if you hold up to a light, you can see the plastic has cracked underneath for like length of the nozzle - those fine hair line cracks you get when plastic is under pressure - and you can feel the fine crack if you slide your nail across. this is noticeable on the right side one. while not that noticeable, on the left nozzle, it is there - but its like <1mm and unless you are specifically looking for it you can't see or feel it to the nail. drivers are working fine afaik and the nozzle hasn't separated or anything. so, should I be concerned about this? is this expected tolerance? or am I looking at RMA?
anyone from massdrop?
I have used these IEMs very lightly over the span of a little more than a month. The left driver is very loose and the right driver seems to be broken (the sound cuts in and out depending on where the cord is moved.) Also, the braided cable no longer works. Was fine with the neutral sound until they stopped working. This is just out of date for Massdrop returns so does anyone know how to claim manufacturer warranty?
Can you use these headphones with the HEM cables or use these cables with the HEM line up?
Nope, you can't. They're of different diameters. .75 for HEM and .77 for EDC3
Hello, I live in South Korea and I bought a Massdrop EDC3. I have a question:
I wanna buy a replacement cable for prepare to cable break. Not a just compatiable, Want a Nuforce stock braided / remote cable bundled with earphone.
If I can, how to buy and how much for price in each?
Thanks you.
(P.S. Is it a 3 way crossover? or 2 way?)
How well would these work for musician IEM use? Broke my 8 year old westone um2 set and these have me curious. Just need to be able to here a band in a monitor mix well.
Dear all, a question:
I have the EDC3 and I love it so much I'm ordering another pair. For the other one I could like to get a Bluetooth cable that connects left and right bud behind the neck. I had one for the UE900 but it had MMCX while this has the 2-pin.
There are many such bluetooth cables available but are all 2-pins compatible? Can you please give me an example of one that would work with EDC3? No audiophile stuff needed, this is for the gym.
absolutely second this request! someone please help us find out which bluetooth cable to use for the EDC3s.
Perhaps a photo with the plugs would help us identify which connectors should be used. I have read that they are 2x 0.78mm connectors somewhere down the thread but I want to be sure before commiting
@hiilari @yoyoma Bluetooth adapters for MMCX are plentiful but 2 pin connectors seem more rare... Here's a totally random one I pulled off of amazon
Pretty darn amazing for the price. I fear these are going to be a gateway drug...
Just received..... and im blown away! These are officially my first iem so ive got nothing to compared to aside from my earphones and headphones. These EDC3 is exactlywhat i want for my collection: superlight wired neutral iems.
i wanted a change from large headphones . I hardly notice im wearing them. Currently using the stock ear tips preinstalled and the fit feels comfortable. Havent tested longer sessions yet but i have found no discomfort whatsoever. It takes some fiddling to adjust the fit for a comfy and tight seal. I wear eyeglasses and it is no discomfort.
Sound is exactly what ive read: very neutral. Nothing overpowering. Depending on what what youre listening to and how well it was mixed, sound stage can have you turning your head at sounds.
i will never switch cables bc i have no use for the wired mic. Though i have my doubts how durable this braided cable is but a least its replaceable! Im glad i made this purchase as this will be my exclusive pair to travel with and part of my EDC.
Thanks for a great product.
Is it a 3way crossover? or 2way? I wanna know, but nobody confirm this ;-;
This is my literal daily driver, having used them since I got it for when I'm not at my desk. It's really rugged and has been to many parts over the world, as I always pack them for my business trips.
Alas, I lost the left side pod today cause the cable connection was quite loose, even though I used the mic cable and I did not remove them after.
Me sad, very sad.... :(
Is this earphones compatible with kz Bluetooth cable?? Has anyone try it yet.
