Hitting the Balance Point… ­ Which one? As many as possible!
Happy Path: My personal history is that I rediscovered headphone listening in 2009, organized local meets, became the Ultimate Ears Ambassador to Head-Fi.org for a time, and now I get to work with audiophile gear every day at Massdrop.
Not-Very-Audiophile Confession: What led me to Head-fi.org was spotting a cool-looking pair of shiny headphones on someone at an airport in Japan and wanting to buy a pair.
I never did find out what that exact pair of headphones was, but I did find a great new headphone. My next super audiophile move was to…buy some HiFiMAN RE-0 in-ear monitors. Loved them but yanked too hard on the cable and lost the left channel. Shopping around for a replacement, I decided to try for extra bass since some people thought the RE-0 were a bit “bass-light”. (Bass insecurity is a thing.) I proceeded to overdo it by buying the Sennheiser IE8 (clublife) and then vowed to go for a neutral monitor. Not too bright, not too bassy, can I find “just right”???
Everyone who knows me in the community knows that I am a big Ultimate Ears Reference Monitor (UERM) fan. I got one of the first pairs as soon as they released and still love them to this day. Many of us think that sound signature is one of the very best and if you had to choose just one headphone or IEM, that would easily be a top 5 pick. The UERM signature plus some sub-bass is fairly viewed as a vision for the “perfect” reference monitor. But would that be the “perfect listening monitor” for most people? Many of us UERM owners have the desire for a complimentary IEM. One that is a bit more lush in the low end in addition to extending lower.
We started this project with the goal of making the perfect reference monitor. We started with a base tuning similar to the Etymotic ER4SR and Ultimate Ears Reference Monitor. Then we looked to add the sub-bass extension. And we really wanted to keep the price to $299.99 so it would be affordable to more people. After a year and a half of experimenting, we got to the point where we achieved elevated but flat bass from the upper bass to the sub-bass with a very clear, flat, and connected midrange (except for a nice little dip in the annoying sibilance region and an extra bump in the presence region to balance the bass).
We’re all at the Rocky Mountain Audio Festival in Colorado right now, where Jude Mansilla from Head-fi.org has organized a big CanJam event. As soon as possible, we’ll get some graphs up on the page. The graphs will show elements of today’s best monitors in the Plus frequency response and the sound has been subjectively described as very musical, clear and fun, with no annoying peaks. It’s a lot of sound, but I can turn ‘em up and not get fatigued. There’s rumble while watching movies but super clear dialog.
This balance of driver characteristics, price, performance, technicalities, flat response, fun sound, and frequency range extension made us freeze this design. If you HAD to only pick only one in-ear monitor or headphone, we hope this would be in your top picks…at any price.

Is it normal for the shells to crack easily? I recently discovered a crack near the nozzle area of the left earpiece extending to around 3/5 of the iem. I've had cheapo iems (KZ ZS3, for example) before and they never cracked like this, I definitely babied them way less than these too. I also heard a popping sound from the same earpiece when I ran it through a bass sweep, dunno if related. I've contacted customer support a few days ago. I hope there's something they can do for my case. I'm fine with the cable dying early (just got in on the Massdrop x Mee balanced cable drop) but I've never had an earpiece crack on me.

Hi desutruction, You shouldn't experience that...someone will reach out for pics.
I just received my massdrop + IEMS
Testing with my setup 1) PC -> Kingrex UD384 -> Hippo Pipe amp 2) Samsung S8+ direct out
It sounds stuffy and harsh - is it due to the output impedance?
I just received my pair. When I plug them into my DAC/Amp after around 30 seconds the sound cuts out completely. After going to unplug them, an electric charge thats powereful enough to shock me can be felt around the base of the cable where 3.5 mm male connector is located. I tested all of my other headphones to confirm that my amp wasn't the issue, and i had zero issues with them. This ileads me to believe it's these headphones, i think i received defective cable with them.
Does anyone know if Massdrop would be willing to send me a replacement cable, or if I'll have to bite the bullet and purchase a replacement out of pocket? If the latter is true, anyone have any recommendations for an after market replacement?
MySensesHaveFailed
I believe massdrop will offer you option of full refund, cable replacement or $50 refund as one of user received faulty cable too. I dont have any recommendation for cable though.
bluetooth
I am having a hard time finding devices which can accurately play music on this because of the issue mentioned by many that the IEMs sound darker when output is > 1ohm. Is there anyway to get around this problem? I really want to use this with an Activo CT 10

I have read that an IFI iEMatch could solve that. Though, I can't tell you firsthand if it actually makes a difference. Here is the source that I am referring to: https://www.reddit.com/r/headphones/comments/8pgv01/just_got_my_massdrop_plus_iems_and_they_sound_a/
CrimsonArmor
OMG Thanks a ton for sharing that info, I never knew such a device existed!!!!
Can someone please compare these to the sennheiser ie80s? It sounds like both are compelling options and I can't choose.
megical_banana
Definitely these. ie80s bass boost is not natural and vocal sound muddy. Massdrop is like an overall improvement of it.
Does anyone know of any ways to make the cables fit more snug into the IEMs? Mine kept detaching with the stock cable, and they continue to do so even after I've switched to Null Audio cables.

Same deal with me. If you look closely I've added a bit of electrical tape on the flat part of the shell to connect to the connector, then wrapped a second piece of tape around the connector to secure the first piece. Works well enough that I don't have to worry about losing the shells anymore.
Anyone else having issues applying the foam tips? I tried twisting and pushing them in but they just won't fit. I'm scared of proceeding any further since there are signs of tear already.
Megalith
Yeah, they are a pain to get on. They fit, but it just take a lot of effort and some luck to get it on. You just have to push and twist at a slight angle until it finally goes through.
I bought these a little over a month ago. Just over a week ago, I messaged support about my included cable dissembling itself in my headphone port. As in, the tip came off the head of the jack and left me with what you see in the picture. No break, just...came apart. Anyway, I still haven't heard anything back. I did get an automated response saying it's been forwarded to the specialist team, but that was 6 days ago. I reached back out to helpdesk@massdrop.com today in hopes that someone would reply but I've got no response yet again. I'm sure I'm not the only one with cable construction issues. Bonus pic: My daughter rocking the HD6XX cans that I love and are my daily drivers when I'm not in the go :)

They did. Options are: Full Refund, Replacement item (whole unit with IEM and cable) or $50 refund. I'm just going to take the refund and rebuy when cable options are improved.
COCustom
I got my reply too and now have a replacement coming my way.
Now while I do think it is a great IEM at a fairly good price point, but yeah that cable leaves something to be desired so you taking that refund was probably for the better.
Anyone heard both massdrop plus and Astell & Kern Billie Jean? Which one is better?

Thanks for telling us. MD Plus it is then :)
General_Prilla
You're welcome. I will get md plus too.
Is there an ETA for the Bluetooth cable yet? Will we be able to buy it separately?
Do these have any water/sweat proof ratings? I'm not intending to swim or work out in them, but if they'll be my daily beaters they might get exposed to sweat/rain.

Anybody have cable recommendations besides Null Audio? The cable for this sucks and I don't want to pay $100 just for a cable, even if it is made from pure unicorn mane or whatever.

Have you had a chance to try it yet? Wondering how much of an improvement 3rd party cables are. I'm not having any problems yet with current cable, just the length is too short for my liking.
timeextended
In my experience, unless the cable is complete garbage (noise/crackle), paying more than a few bucks for 3rd-party cables is paying for diminishing returns.
Is that cable ever coming back in stock, or can one of the audiophiles here recommend a better one so that I can buy separately and make my order? Been waiting for a while to place now. Thanks.
qtquazar
I've heard great things about Null Audio's ethos cable and you can literally select Massdrop Plus in the customization options. This is probably the cable I will pick up if I have problems with the stock one.

@CEE_TEE hi, i just want to as whether the inside of the earphone is hollow or solid?
Stvnar
The shells are not filled in...the bass drivers are vented. A few designs have the shell filled in, but drivers mounted in a hollow shell is the norm.
how long will it ships to Malaysia ? Just want to know because I want to expect its arrival if I have to wait for months then unfortunately not a choice

u got urs yet?
Just bought these second hand. I tried my friends and these seem like the bass just isn’t there. Is it possible to blow out an iems?
seller full disclosure said he connected to 4ohm output amp (dragonfly red) at full volumn. i know dynamic drivers blow out but I thought bas were more durable? Cause for concern?
JustmeAL
I have the dragonfly red, and I can run my hd700's comfortably at half volume on it; full volume seems absurd for an IEM, so there is a decent chance that the bass drivers blew out.
This pair versus this very well received pair of BA IEMs (https://www.aliexpress.com/store/product/FiiO-FH5-Metal-Case-Knowles-Detachable-Cable-MMCX-Design-Quad-Driver-Hybrid-HIFI-Earphone-3-5mm/1473108_32900255794.html?spm=2114.12010608.0.0.5bb5e72864GaZb)
w/o being able to listen to either, it's tough and massdrop returns are so painful and slow I consider any product I buy here final.

Thanks for this. Judging by the DR chart alone, it would seem this pair a tad strong in the 10k-20k FR, In fact would seem treble is more responsive than the bass. I'm super treble sensitive and seeing that curve is sort off-putting to me. Not a criticism of these IEM, just the type of listener I am.
rdodev
On the stock single flange sillicone tips some tracks do have sibilance. i stuck to using the supplied double flange tips and never had an issue with shouty vocals, or sibilance pierce.
Running them through a player w <2ohm impedence, they sound good to me. anything above that level of impedence makes the sound too warm for my liking.
Where can I get these foam ear tips That comes with Massdrop plus IEM?
Give me some info on two options. Thinking of this OR the Noble Kaiser 10 Custom. 1000 dollar difference..
I am NOT an audiophile but like good sound. Budget is not an issue here but do not like to spend more money than I should.
I like my P7 wireless, I like my HD6XX more but Edition X V2 is my first choice.
Why but this OR Noble Kaiser 10 Custom? Pro and cons?
Not looking for end-game but want to buy a set of portables that I will really like for years. Music taste is as random it can be. Woman vocals maybe a little more on playlist but likes Metallica, symphonies and bass as well.

My friend owned a kaiser 10 universal. Sounding wise is exceptionally good on female vocals and being good on the others. My only problem with it is it is somewhat bright. Turns out to be the poor cable quality, change it and you will be fine. Another issue worth mentioning is how sensitive it is to your source output (DAC/AMP). Normal laptop aux or mobile phone will have noticeable hissing noise.
Kaiser 10 and MD+ both are really different in sound signature. And if you are looking for a earphone that suits to your listening, an audition is highly recommended. My friend who love his kaiser 10 now dont really like andromeda or UE 18+. TOTL earphones are really all comes down to your own preferences than technical terms. But since you are using HD6XX, i assume you will like the kaiser 10 more.

Forgot one detail - primary use on the go. But sometimes connected to iFi black at home. No portable dap yet, but maybe in future, iphone 7+ will be used often.
Just be careful to grasp the IEM itself when pulling these out of your ear. Don’t use the cable. The cable detaches VERY easily. I’m getting a new cable from 64 that hopefully stays in a little more securely. It sounds great though.
UPDATE: the left channel has starting buzzing. Not sure why. They're unusable now.

The 64 audio cable is better. It seems to stay in better and it gets less tangled.
triggsviola
Which cable? The $129 "Premium Cable"? The Recessed one? It just seems a little steep for me, but it looks nice! I'm hoping to catch it on sale, or used.
These look exactly like the ultimate ears from a few years back
I just received my Massdrop Plus IEMs, and they sound great so far. However there seems to be a problem with pinging in the right driver shell. It's not the normal low pitched microphonic rumblings that I'm used to, but a higher pitched ping from inside the shell itself just like the sound a wonky mechanical keyboard switch makes. It's noticeable when touching the shell when it's in my ear, very noticeable when tapping the shell, and to a lesser extent it pings alongside cable microphonics. The left side doesn't ping, it only makes the normal low pitched microphonic sounds. Is this something I should contact support about, or is this pinging normal? I couldn't find anything about a ping sound in iem shells when I searched for it, and it seems like an issue because it's only on one side. Thanks.

Turns out this was a defect in the right driver. I discussed with a member of the engineering support team who was very helpful and able to resolve things for me.
Whats the difference between the stock and 30$ cable?
Some earphones I've tried with the loop-around-the-ear style always fall out a bit for me. These look better molded to the ear than what I've tried, but can anybody comment on that aspect? Granted, the ones I tried were under $50.
Is this better than the noble x?

How so?

I wouldn't say they're better, just different. The MD+ is arguably the more resolving pair with a better soundstage and imaging. The Noble is definitely more musical, fun, and slightly dark (but not v-shaped). It's not trying to be as neutral and flat as the MD+ but brings a level of dynamics to the music that the MD+ doesn't. Comfort wise, the MD+ is superior as the Noble is more of a pain to stay seated. Both are easy to drive from a cellphone but the MD+ is more perceptible to output impedance (it prefers something under 1 ohm) and it can change the sound slightly. The Noble didn't seem to care and sounded the same no matter what I used them with.
It'll boil down to what you prefer, something neutral/flat or something musical and fun? I like both depending on genre and mood.
