For potential buyers in Norway, Sweden or Finland. Head over to moetaudio.com, they have these 25% off.
Have a pair of these myself, and they are absolute beasts! Give them about 100-150 hours run in, and they cant be beaten in this pricerange!
I am confused. From reading the specifications it seems there are actually two drivers. One electrostatic, and one 40mm dynamic. So, is this some kind of hybrid or am I missing something?

Yes it is true that dynamic drivers are slower than electrets/electrostatics. But, they are using the slower dynamic driver to play the bass notes (which are slower). This concept has been used in many home speakers. Check out Martin Logan. The trick, as you mentioned, is to meld the two driver's into a coherent sound. The Mitchel & Johnson do a very good job of this.
The dynamic driver advantage is the amount of impact the bass has. Electrets/electrostats can't move much air in the bass frequencies. Look how panels are built - tightly stretched like a drum head. A dynamic driver can move back and forth much more. The only way for the electret/electrostat to make up for the shortfall, is to use a much larger panel. There are limits for what people will wear on their head.
Most of the electrostatic home speaker manufacturers advertise their hybrid speakers as electrostatic. It is the more expensive tech.
I agree that the Mitchell & Johnson don't sound exactly like $2000 Stax. But, the Stax I've heard are open back. These are closed. The MJ can be enjoyed in noisy environments. That is important since they are designed for listening on the go. enjoyed
No technology or product can do everything. The MJ2 give us a different choice. Just like the hybrid trend of adding balanced armature drivers to dynamic in ear monitors.
The MJ2 are nice sounding headphones. They do require break in. Don't even try to judge them without break in. Even though they are very efficient to drive, not every phone or dap can control the dynamic bass driver. Like most "speakers" they do better with better equipment.

I understand what you're saying but there is one bone of contention in that bass frequencies are not necessarily slower as sound travels at the same speed regardless of frequency. However the mass of a driver designed to reproduce bass is usually higher and therefore it reacts, and recovers, much slower. That's why speaker designers who plan to marry a dynamic woofer with a planar or electrostatic mid and tweeter, try to build low frequency drivers that are really rigid, with as low a mass as possible. As a bass player, a Martin Logan owner as well as a Magnepan owner and recording engineer, I know that the bass is not slower. Gale Saunders of ML says he has to cheat a bit in the crossover network, to get his hybrid's woofers to work well with the electrostatic mid/high drivers. On the other hand the Maggies are planar drivers throughout with plenty of bass output due to the larger area devoted to reproducing lower frequencies. Hence the drivers being of the same material, and driven uniformly, are equally as fast and you will hear those parts of the bass frequencies that are anything but slow. In other words, you will hear the detail and definition of the bass notes.
Even standard cone speakers have the problem of differences in the mass of the drivers, the smaller tweeter being quicker reacting than the woofer. Bottom line: any perceived slowness in bass reproduction is more due to reaction time of the higher mass woofer than the actual bass frequencies themselves.
Please try actual electrostatic headphones. Like stax. B4 buying. Cause these doesnt sound anything like electrostats

Just checking...assuming you own the MJ2's and some electrostatic cans (Stax?). If so, it'd be helpful to know which model(s) you own and for you to write up a brief comparison to the MJ2's. Thanks!
Lol. M&J must never had heard electrostatic headphones. These pair are terrible
I'm new to the world of high-end headphones. What size cable plugs will work with MJ2 and Callio DAC?
My MJ2 is just arrived. For potential buyers outside USA a warning ! You have to pay Custom duties and VAT ! That was a disapointment because my Matrix HPA3B headphone amp. from Massdrop was without Custom duties and VAT. Still an attractive price but not more a steal.

All I can find is you're saying you are disappointed there was a VAT tax

Never mind, I see it. Sounds like they are not anything special
Electret drivers aren't new; Audio-Technica made a pair some years ago, along with an adapter box. Electrets are somewhat higher-mass, so their "transient" behavior isn't quite as good. There are also self-energizing electrostatic headphones (such as the original Koss ESP-6). These might require more power than dynamic 'phones, but not special amplification is needed.
Is there any measurements? I usually look at the ones on Inner Fidelity but he hasn't done it for MJ2.
Measurements = reality.
David Choy of Triton Audio Cables has found the solution for making a balanced cable for these cans, no need to plug the original cable in and out. I had mine made recently.
I would really like clarification from MJ about how the stock cable is wired at the headphone cup. There is no mention on the MJ website about the cable; they don't even state the length of the cable. Massdrop only quotes what the manufacturer tells them and doesn't provide any specs about the cable. The only way I learned that the cable may not be wired in the 'normal' manner on the cup end is thru reading reviews and reading here in this discussion. I sent an email to MJ Sunday night asking for clarification and a wiring diagram but have not received a response. I have some aftermarket cables that I either made or purchased and I would like to know if they will work with the MJ2 when I receive it.
I don't understand what MJ was trying to accomplish with their cable that supposedly allows you to plug the cable into the cups without worrying about which plug is left or right and still have the proper channels connected. Someone said the idea is that you can plug the cable in in the dark and not have to worry that the channels are correct and not possibly reversed. But the phones themselves are labeled L and R, so you would have to be able to see the phones before you put them on to get them properly oriented. So it seems to me you would orient the phones and orient the cables that should also be marked L and R and then you can turn out the lights and all is well. It seems to me that MJ was trying to address a 'problem' that really doesn't need to be addressed with their unorthodox cable wiring.
So, if the stock cable is wired as stated in the post below with the L channel as tip/sleeve and the R channel as ring/sleeve, then no aftermarket cable is going to work. You will need to have a cable wired only for the MJ2. It may be possible to open up the cups and rewire the wires from the connector to the drivers to match your cable but I hope that's not the case. Maybe someone here who already has the MJ2 and has only used the stock cable can check the continuity from the cup connectors to the amp plug and tell us how the cable is wired. Would be nice to know this before the phones arrive so I can possibly be prepared with a balanced cable using a 4-pin Neutrik connector on the amp end.
Of course it would be ideal if MJ would respond and clarify this. As I said above, an email to them thru their website asking for clarification4 days ago has not elicited a response.

I know nothing about these headphones, but the monoprice M560 has a design that sounds like what might be used here: the cable is a y-cable with identical stereo plugs going to both cups. The left cup only plays the left channel, and the right cup only plays the right channel. So it doesn't matter which plug goes to which cup -- you could do it in the dark.
You could still make a balanced cable for a headphone that is wired this way, but you would have to mark the cable L and R, since there the two channels do not share a common ground.
HappyMax
That's right. You only have to pay attention at the earcups. Left earcup at the left ear and right earcup at the right ear and it's automatic ok !
Apologies for a long post. I have always wanted an Electrostatic headphone. Loved the MJ2 for the portability and cost. I’ve been on a major balanced headphone trip recently, so I talked to David Choy at Triton Audio Cables about a balanced cable for the MJ2. He had the foresight to say that they were new to him and that he needed to test the polarity of the headphone terminals first. So, I had the cans shipped to him direct. He was right. The polarity was unusual. So, David customised the balanced cable for the MJ2.
When I received it and plugged it in, this happened: (excerpts from my email to him). “Got the shipment with the MJ2. Need to pick your brains. Something strange with the MJ2 cable. When I plugged it into the headphones I heard nothing. I checked the connection and the settings in the Onkyo DP-X1. I thought maybe the TRRS scheme in the DAP balanced-in was unusual, just like you had said the MJ2 connection was. When I couldn’t get a peep out of the DAP, I thought maybe the headphone was kaput. I used the native unbalanced MJ2 cable. Great sound! I listened for some time and decided to reconnect with your cable. Lo and behold, amazing sound! I listened for a long time. The audio was wonderful. Later, I reconnected the native cable through a headphone amp. This is a hungry headphone. After sometime, back to your balanced cable. No sound again. Change to different cable, sounding fine. Back to your balanced cable, great sound again. I went through this experiment several times with the same result each time. I’m flummoxed. Clearly your cable is fine. But why is this happening? When used with a balanced cable, does it have trouble functioning? Anyway, when it works, your cable sounds fantastic”.
These were David’s replies: 1. “When I tested the original cable, I noticed that the headphone knows which is left and right and it doesn't matter which one is plugged into the left or right, the sound somehow comes out of the correct channel. I guess that's why the stock 3.5mm headphone end connectors aren't labeled L/R like most cables. Just now, I found this information that describes the issue completely: "The MJ2 do have left & right indicated on the inside of the headband, near the earcups. As you mention, the cables aren’t marked. This drove me crazy until discovering they don’t need to be! Mitchell & Johnson did something brilliant. They ran the left and right channel to both earcups using a 3.5mm trs plug. The internal female connector is only wired for the correct channel. There’s no way to plug the cable in with reversed channels. This feature is lost if balanced cables are substituted." It sounds like the only work around is what what you discovered and executed due to the unique wiring in the MJ2. Perhaps I didn't experience what you did because I used a 2.5mm balanced to 3.5mm stereo adapter and it worked great. However, I have a theory that due to the way the MJ2 has both right and left channels in each ear cup, if the 3.5mm headphone connectors on the cable have the tip and ring solder points bridged, then it might work, and like the stock cable it may not matter which side is connected to the headphone. The cable you have now has Tip/Sleeve for left channel, and Ring/Sleeve for right channel. The caveat is that I cannot guarantee that it would work as I don't have an MJ2 on hand. I hope what I wrote makes sense”. 2. “I'll formulate a post in the MJ2 thread on head-fi. Sounds like a few people have balanced cables. I'm wondering if the balanced connection at the 2.5mm TRRS may be causing the issue if the headphone connectors on the left and right driver housing is able to determine a stereo connection for each appropriate L/R channel because the ground is common for both sides. With balanced, they are separated. I haven't seen a MJ2 opened up to see the PCB board, but I surmise that the separate grounds versus common ground is the culprit. Why the balanced cable works after the stock cable is inserted, I can only guess that some electrical components is able to get a charge (perhaps in a capacitor) long enough so that when the stock cable and balance cable is swapped, it works.” Makes sense to me. Has anyone else had a problem like this with the MJ2? What do the Illuminati at HeadFi think?
I bought those on Indiegogo a while ago. After a very long burn in they are doing good. Try a balanced cable. This will make them really shine.

Where did you get your balanced cable? Please my post and tell me if you’ve had the same problem.
So.... shipping is limited to the US, but it says under the price it says "Ships to GB", please fix and stop teasing me...
twistercoo
just checked they are shipping worldwide
everton66
Thanks for that,.. Gonna go for it,
If anyone is looking for a pair of these headphones, I have one for sale at the offering price ($340). Apparently I somehow bought two pairs at the same time. Massdrop refuses to take one set back. Otherwise I will list on Ebay or Amazaon (retail is $500). James. 917-242-1889. jldooley61@gmail.com.

You realize it's selling for 299.00 here right? With warranty.
Looking forward to getting & hearing these in my system. It was a pair of Audio-Technica ATH-7 (an electret condenser design) back in 1979, that got me jump-started on this crazy audio, headphone, sojourn, quest, obsession....
Denf
I have AT electrets. You are in for a treat with the MJ2.
Of course I paid a lot more, but nothing beats my HK901s!

Lmao, if that's the description your 5 year old daughter gave, I can't wait until I have kids.
Would buy if they shipped to UK...where M&J are based...and where I live... aargh!!!
(I know that MD is based in the states..but still aargh!!!)
Oh hi MarkUp, sorry you didn't like the budget model GL1. I have the GL2 SE (kickstarter mid-tier model based on Verisonix technology just like the MJ2) and they are absolutely brilliant for the money - they just need a little running in time to get on song. Final design GL2 SE model is currently £300 on Amazon UK. These superior MJ2 phones are currently £472 on Amazon UK so a real steal at 340 dollars Massdrop!!
Oh by the way, just to correct a little 'fake news' below...Mitchell & Johnson is an established British Hi-Fi company founded by Paul Mitchell and David Johnson.

Thank you for the tip! Like many good amps and speakers, they need "break time" time. Good to remember.
KlektiX
You can call them direct and ask for the Massdrop price explaining the geography issue and I can't imagine why they wouldn't help you out.
Would buy if they shipped internation.
I bought and tested a more affordable model from this company. Their GL1... Painful to wear and some of the worst that I have ever heard. Boxy, harsh and boomy yet lacking low sub bass. Maybe defective? Not likely. Those are $300 on Amazon and not even worth $50.
Oh, get this. Another company with a clever two person name pulled out of thin air I presume called Tate & Bauer has this near identical electrostat, the HD900R (go look it up) for $80. Good God these look a bit like a once $300 now $30 Sharkk Bravo nightmares.

The Sharkk's were the WORST! I actually put them in the garbage.

GL2 was just as bad. Felt like a cheap kids toy and sounded like crap.
what is the removable cable connector to the cans? 2.5mm?

True about the custom cables. Think Denon has used the same setup on a couple of models. As a kludge, one could use three 3.5mm trs aux cables and a 2 way splitter. Messy, but works in an emergency. I use a diy balanced cable so both channels don't run to each earcup. Like 3.5mm much better than 2.5mm connectors.
Dasman is correct. There are a ton of cables that'll fit from factory units. The Monolith 1060's which have very long braided cable would work just fine!

Perhaps you could clarify what you mean by "their connection- if any- with Verisonix. A search of the page for "Verisonix" shows 1 press release, which is a bit vague like most are, but seems to me to say Verisonix developed, patented, and manufactures them, and M&J focuses on sales, pricing, distribution (and perhaps tuning). Certainly sounds like a relationship, but not an exclusive one (re: Sharkk / B&T.)
So yeah. Kinda want these. But at the same time, do I really want fake electrostatics? These are just about half the cost of KOSS ESP-950 or STAX SR-207 (with amps).

Yes Fayne is correct. ESP950 the current model.
Well known for electrostats. Someone else said it was possible to buy those at a much greater price. Just pointing out the MJ2 hold their own.

they get decent reviews both on Amzon and headfi. Quoting someone from headfi "so far my impressions are very positive, especially for their $85 price. They have caveats; short cord, worthless BT adapter, shallow earpads, and a plasticky overall feel, but in sound they're damned good, especially in the mids and upper bass region. They remind me a whole lot of the old Stax electret cans, only with fuller bass and more textured mids, like ESP-950s with a more narrow soundstage but better bass extension. They have me intrigued and I'm going to spend more time with them. In fact, going by sound alone, if someone had told me these were $500 I wouldn't have batted an eye."
mahee
Cool!!! Sounds Pretty Good. Thank you for all your effort in answering my question:)
Great sounding headphones. I've owned these for over a year. My favorites.
Wake up guys. This is not a “new exciting hifi company”, just an OEM product from Taiwan.

I guess that's for JP1 or MJ1. MJ2 should be more expensive. Anyway, none of them worth the money IMO.
What material are the ear pads made of and are they replaceable?
HowardC
The pads are a pleather type material and are replaceable. They can be wiped clean with a damp cloth. Ear cups have a small slit all the way around. The earpads have a small flap that pushes in to the slit. Same system that many other headphones use.
I have the JP1 version of these and they are amazing headphones with accuracy and detail that will keep you searching for DSD files to play through them. If these sound half as good as the JP1 they are worth double the massdrop price.
