When will the next drop after this one be? Not sure if I should buy now
OdinFK
Don't worry about the "xx hours left" anymore when it comes to this drop. It's on a constant timer. Massdrop refreshes the drop every 24 hours, so it's been permanently available for the last few months.
I was thinking of picking these up but noticed they have 300ohm impedance. I don't think they'd be powered well enough from my new MacBook air's ports. I do have a USB dac that I sometimes use, but not sure if utilizing the USB C port vs the headphone port provides the headphones with more power or not. Anyone have any insight? I do not want to buy a separate amp since I'm almost never at a desk when I am on my laptop. Otherwise, I'll just go for a pair of hifiman 4xx.

For HD 6XX, you need an amp that provides atleast 1V for reproducing the entire dynamic range of modern music. Iphones, LG V20/30 and some Samsung Galaxy phones can output 1V which is sufficient. There are many USB DACs that can also provide such high voltage.
Thank you massdrop and Sennheiser for making a audiophiles grade product at a great price. This is what great partnerships are all about. Phenomenal clarity, detail, without any fatigue to your ear drum or head.
Why this item can't ship to Thailand?
Does anyone know standard delivery charge for these to England, UK?
A clean, open sound, with a nice amount of base, and not at all fatiguing to listen to for long periods, and comfortable enough that i forget i have them on. However, it does make a lot of squeaking when worn with glasses, which is irritating. Any solutions?

You can temporarily put masking tape around your glasses where the contact is. The grip from the headphones catches the smooth surface of your glasses, like rubber on wood floors.

Thanks for the explanation, that makes sense, it's less egregious than it was. so i think it's improving. but i'll give masking tape a go if i can find my spare specs. Dekoni pads may be a good long term solution.
massdrop, mind to give a black friday discount on this too ? XD
I'm wanting to buy these 6xx's today, but I'm in the Netherlands, does anyone know if i'll be hit with import costs on top of this purchase?
CookieMonster2000
Most likely. It's something that always comes up when massdrop is involved with shipping things to EU
Kosior
Thank you. You're totally right, I googled it and got all kinds of horror stories from people in the NL about Massdrop shipping. I would be hit with around 60-80EUR in import costs and fees on this purchase for the HD6xx. I can't buy it unfortunately. Its a bummer that Massdrop doesnt just have a EU base to ship from.
Just received my pair and I coupled it with a new schiit magni 3 because folks seem to like that amp to power headphones such as these that require power. Only problem is, the 6xx's failed with some very low bass on the first track that I played through them. The high's also seem to get lost a bit in the mid-tones. My source is vinyl on a pro-ject debut iii with an entry level phono pre-amp and some junky rca cables. I realize part of the problem could be the cables, but I suspect it's something else. Does anyone think that the darkvoice amp would be better? Should I return the schiit magni 3 and invest in the darkvoice and a better cartridge on my table? Does anyone think the problem could be a defect with the headphones themselves? I'm really kinda struggling here. Any and all feedback would be very much appreciated.

I think your expectations are too high. HD 6XX are open back dynamic headphones and in general, they don't reproduce sub-bass. You can go to rtings.com and compare HD 650(HD 6XX equivalent?) with some other headphone that you know very well. That should reset expectations. I don't think the amp is the problem.
I have just ordered this and will be getting this in a few days. I was wondering if this is compatible with a modmic? anyone have any experience with it?
Jezzy
i imagine you wont have problems with a modmic. If the microphone has its own mic input, then you wont have a problem. The Sennheisers don't use 3.5mm connectors to the cans, so your mic will need to connect to the computer seperately. However, I have little doubt that you would have trouble ATTACHING the modmic.
Received mine yesterday, initial impression they felt a little plasticky for this range of headphones. Bulky cable. But don't let that influence you... Tested so far with: Iphone Xs + Apple cable DAC/amp: Not enough drive, fells way short. GrubDac -> JDS Labs C421: Lots of drive and dynamics on low gain setting. Gritty highs, slight bass lacking easily "fixable" by enabling bass enhance. (GrubDAC already has grainy highs) Macbook2,1: OK drive, sweet sound for a 2006 computer! (sweetest built-in audio laptop I've ever had) Macbook2,1 -> Pete Millet Hybrid (Headwize edition, Millet Max, MOSFET Diamond Buffer, Sylvania 12FK6, 30VDC) Now we're talking... this amp has plenty headroom to drive the 6XX, and that's apparent in the sound, effortless, dynamic, good detail (for a 2006 source!) loved the highs rendition, preserves the grit if is already on the original recording, but always makes them more bearable. Sonic signature with this rig could be described as "Lush, Oldie Hi-Fi". Not the most detailed, or ultra-resolving, but really enjoyable nonetheless, it is actually hard to find something bad sounding, all frequency bands nicely weave together.

I also compared against AKG K701 on all setups... preferred HD6XX on all.

If you own HD6xx, the DarkVoice 336 should be an incredible match, do you have those? I'm waiting for my DV336 to arrive and will update, along with any worthy mods to the amp. I think I also have a SOHA, and an unfinished Bijou... will test and report too. Good thing regarding that amp is if you don't like the sound, it will be really easy to sell as it's a highly regarded amp by the thousands of Senn 6XX owners. Most sonic characteristics will be determined by your source, so if you don't have an USB DAC already, you should consider getting one, those can be get really cheap from ebay on a budget. Built in audio cards on PCs are horrible. I think an AKM4396 based DAC should match greatly the sonic signature of the HD6XX (lush bass, glossy mids and feathery but detailed highs, I have a DAC based around it I love). I haven't tested https://www.massdrop.com/buy/audioengine-d3 but could be a worthy first purchase, moving to D3->DV 336 ->HD6XX afterwards.
For those on a lower budget, O2 could be another option: https://www.massdrop.com/buy/massdrop-o2-amplifier and to get into opamp rolling to chase your preferred sound signature.
For shipment within US, will USPS be used for delivery? And will we receive tracking number when item being send out? Thanks!
I really like to pull the trigger on this. But the 300 ohm impedance kinda worries me and I currently don't have any plan investing DAC/AMP yet. Can someone please recommend a portable DAP that is powerful enough to drive this baby without using High Gain?? Many Thanks!!
Hey, all. I bought a pair of these here for my S.O. back in July and he doesn't like the way they fit his head. He wore them approximately 5 minutes. I'm looking to find them a new home for a bit less than the price of this drop, S&H included. If interested, ping me at junquet1 at gmail

He has his charms. And he did like the Massdrop x AKG K7XX headphones I got him, so there's that.
Oops, missed that. Ha!
Wonder who's gonna get the SN 60000 pair
flasew
Would be cool :-) The S/N seems to be a bit random - when I ordered, the number of "sold" was in the 57k+ range but the cans I received have S/N sub-48k
Is there a reason this drop doesn't ship to Taiwan? I've bought other electronics here and had no problem having it shipped here. Really wanted to pick up these headphones. Amazon will ship similar products without issues too, but I'd prefer this massdrop 6XX edition. Even the Massdrop x Sennheiser PC37X ship to Taiwan and they're basically the same category of product, and less than $100 cheaper :(
do these work for gaming
Just a note: Most adult human beings cannot hear above the mid to upper teens so the listed 41 Khz goes probably further than dogs can here. #Pointless spec.

In other words: Audio-purist speak for: "I can brag about this spec when showing my friends."
GimmeDaGoods
A car can do 0-60 in 4 seconds and has a top speed of 220 mph. These are unusable specs to most people, but it gives information about the capabilities of the car and its engine. Yes you could also brag if you wanted, but that doesn't make it useless information.
i have a yamaha mg10xu is this a good mixer for these headphones?

Will my Yamaha mixer power them well enough
jonwhite2227
I dunno. If it's AC powered and has a headphone jack/amp installed I don't see why not. You're welcome.
Ι don't understand, they are made in Ireland but ship from the US?

The import tax to the EU is 0,5% (negligible) (NOT 12%) You cannot avoid paying VAT, if it were sent from Ireland, you'd either pay Irish or Belgian VAT. The price would be $199+VAT The freight might be lower, though at $15 it's hard to see how Enviromentally it'd be obviously better and less (=no) hassle to get it through customs
WilcoRoger
It's Belgian import tax that's 12%, quite possible that some amount of it goes to the 0.5% of the EU. On top of that, just about every shipper I've already dealt with adds a hefty handling fee for the tax administration & upfront payment. In my experience VAT gets calculated on that as well ...
I have a Fiio x5 Mk2 for DAP. Will these go well with them. For me its between these and the 58x and i cant decide.
Which amp for these? The $99 US Schiit Magni 3 is $209 AUS but it looks like the amp to get. BUT There is a massdrop on the O2, but I do not know A - a good choice vs the Schiit? (shipping is much cheaper at $15 US) and I like this idea B - which spec to get in regards to;
  • Gain: 2.5x and 6.5x / 1.0x and 3.3x (select your configuration)

For these the high output impedance of A30 doesn't matter: as it's 10 Ohm, it's comfortably below 1/8 of the headphone impedance.
I mostly got it because it is portable but have used it my desktop almost exclusively.
Gotta love Fed Ex. Dropped $15 extra for 2-day and it's past the delivery date. RIP that extra cash.
I got these delivered in a couple of weeks to Belgium through DHL (it got stuck for over a week in Germany at the DHL sorting/import centres). I had to pay a whopping € 135 extra fees!!! (20 euro customs, 30 euro "customs administration", 85 euro VAT). To be honest I have no clue how they got to 85 euro VAT, that's almost 50% of the value of the headphones!!! No way to discuss the prices either, they're printed on the box and that's what I had to pay or not receive them.

How did you get to 299 dollars? It's clearly listed as 199 dollars. (On the shipment papers too)
BelgianCustomer
Very good question ... I don't know, confused I guess 🤔
I have a pair of HD 6XX that I'd like to sell if anyone is interested. They have about 4 hours on them. I don't see a way to directly contact a Massdrop member short of putting my contact info into this discussion, which I don't want to do. If you know of a way, please let me know. Thanks in advance.

Sorry - Sold

im interested in bying just need to know the price and which country you´re lacated in.
Massdrop really needs to improve their shipping options outside the continental US. Without a way to rush the shipping, it literally takes a month to receive anything from Massdrop. Why not mail it USPS instead of having FedEx sit on it for 3.5 weeks? And I got an email from FedEx saying that they’re now delaying it a day longer. Seriously? Time to step it up, Massdrop.

Yep, why use Massdrop at all if you're prepared to pay extra for speed? There's nothing better about the 6XX- the cable is inferior, the boxing isn't quite as nice, you won't have a local warranty. Personally, I use Massdrop because they are cheap. I also put up with their slow international deliveries (and sometimes have to jump through shipping hoops for stuff like the 6XX which won't ship to Asia). If I wanted something immediately, I'd just buy local.

HD 650 Retail Price: $499.95 HD 650 Amazon Price: $319.00 HD 6xx Massdrop: $199.00 If I paid $30 for 7-day shipping, it would be worth it. Troll.
Be very wary if you're purchasing these and you're outside of Americas. I am from England and bought these about a week ago, they have been stuck in customs due to going through "clearance processing", today I was greeted with a letter about said customs and that I owe $57.87 in custom fees, handling fees and the like. Just be careful as 44.XX GBP is very expensive for customs fees, added on top of the headphones cost and then adding on top of that, the shipping costs.

Ah you see, I didn't know this when I bought the headphones. Thank you for pointing this out to me though, much obliged.
Fragility
Did you receive the headphones ???, I'm really worried here.
Would sennheiser GSX 1000 be good enough to drive theses? or would I need another AMP I am currently using the GSX 1000 with my HD 598 - they are only used for PC gaming and nothing else. Would love to buy these but unsure if I would notice much difference. https://en-au.sennheiser.com/audio-amplifier-gsx-1000 Thanks
I got these second-hand and, in case you haven't been convinced yet, BUY THESE! These are *the best* headphones for $200 bar none. They are slightly light on the bass if you're used to consumer headphones like Bose, Beats, or B&W (The B stands for bass). However, these have the most natural mid range of any headphone at the price range I know of and an easy-going treble that makes everything so pleasant to listen to. GET THEM NOW!!
I waited a long time before deciding to buy these. Glad I finally did. They sound great! I do a lot of critical listening for sound design, music and dialogue production and these are a great tool for reference. I normally use Beyerdaynamic DT770s for tracking and these feel just as good if not better for fit and comfort. Sound wise, I feel like they are slightly more precise the DT770s and very pleasant to listen to for long periods. I will not be giving up my DT770s but the Sennheiser 6xx has definitely found a home with me. I love them!
