Product Description
A collaboration with world-renowned headphone manufacturer Beyerdynamic, the DT 177X GO has the kind of German-made quality you can see, hear, and feel. Based on the DT 1770 PRO, it uses the latest generation of 45-millimeter Tesla drivers for a wide frequency range and a weighty, controlled bass ... Read More

THE PATH TO THE ULTIMATE LUXURIOUS, FUN, TRANSPORTABLE CLOSED BACK HEADPHONE Beyerdynamic started in 1924 and they are known for making the first modern headphones. Year 1937:  Beyerdynamic DT 48. “DT” stands for “Dynamic Telephone”.
search
Over the following 70 years, Beyerdynamic would achieve incredible feats in headphone development. From developing the first dynamic driver with over one Tesla of magnetic field strength, to summiting Mt. Beyer. Jokes aside, without Beyerdynamic, headphones and our community would not be where they are today. We’ve been pursuing this collaboration for years and we couldn’t be more excited to show you the DT 177X GO:
search
FROM PRO...TO GO! The DT 1770 PRO version was originally designed for mixing desks and professional audio interfaces.  The PRO version needs more power to operate the drivers and was designed to show flaws in recordings. From the Beyerdynamic website: “The DT 1770 PRO are the ideal headphones for live acts as the extremely high efficiency drivers assure a perfect listening experience in the loudest environments.” We worked with Beyerdynamic to modify their DT 1770 PRO version and make it better for our community and the kind of music listening that we do: from a sit-stand desk, at a coffee shop, or around the home.   Tuning The DT 177X GO has a slightly smoother sound, with some additional damping. Designed for the home versus a recording studio or concert venue. Power The DT 177X GO is easier to drive from low power devices, along with the added capability of balanced drive built into the earcup connector. (We’re working on a 2.5mm TRRS Balanced cable for Digital Audio Players and Bluetooth Pucks made by Astell&Kern, Cayin, Earstudio, FiiO, iBasso, Onkyo, Questyle, and others.) Here are a couple of gear combos that we have been enjoying around the office… In use with Astell&Kern XB10 (can use Single-ended 3.5mm or Balanced 2.5mm):

In use with EarStudio ES100(can use Single-ended 3.5mm or Balanced 2.5mm):

We’re also working on a Lightning Cable and investigating a USB-C version...
search
Our classic line of desktop amps certainly gives a great performance using both single ended (Cavalli Tube Hybrid) and balanced (THX AAA 789) outputs.  However being able to step away from the desk with just a laptop or portable player and continuing to enjoy such excellent sound quality and dynamics has been a real treat that we are happy to finally share with you!

Thanks for the confirmation. I discovered 20 minutes after the drop ended you can order separate cases for the 1770/1990. So to those that bought the 177X and want a case, feel free to head over to the Beyerdynamic website and find your case :)

I'm looking into upgrading from my ATH-M50X and have been looking at the HD6XX recently. Any thoughts on which of the HD6XX and DT177X would be the better option? I know the main thing is open-back vs. closed-back, but any other input? I don't own an amp as of right now.

I own the 6XX and they are 300 ohm, which means you really should invest in an amp to power them. The DT 177X are 32 ohm, so they are designed for use without an amp. Not sure on sound vs DT177X as they are not officially out yet.

You definitely need at least a cheap decent amp for the 6xx (Liquid Spark or JDS Labs, not Magni 3), and bass will not be super impressive. The Massdrop CTH helped me notice more 6xx details, for example on Aja by Steely Dan, but the 6xx will never satisfy my bass desires. On the other hand, the 6xx is an industry standard which you can use to gauge reviewers.

I would say they probably do. They also leak sound, so if you need a portable pair, these might not be the best option. For home use, they are absolutely fantastic.

Seemed (at first read) to be the portable headphones I definitely need :
  • closed back
  • low impedance
  • Beyer sound signature
  • No harsh treble (!= 1770 pro)
But I won'y buy them until clarification about the upcoming several cable options (sold individually, or as a future bundle), and the EU shipping. I definitely won't pay shipping + taxes + DHL customs clearance fees, first for the headphones, then for a balanced cable that will be released as a later upgrade, while both of them are manufactured only 500 kilometers away from me (it would cost me less if I drive directly to their factory). The deal is definitely great for US residents only. In EU, it seems better considering other options. NB: It is also sad not to provide a case for a so-called portable headset. Anyway, I could reuse my Amiron's case if I decide one day to buy these 177x.

"scales slightly with better gear" so it only sound slightly better with a good amp vs a smartphone? Must not be very good then.

Try the DT880s (but seriously, just get the 250 ohm, atleast), it is tuned much more neutrally than most Beyers, and unlike Amiron is available in a ruler flat phased, 600 ohms (and for under $150!). The HD800s, that Senn would release ~20 years later at close to 10x the price has a remarkably similar tuning. If you spend some time with a range of Beyers, I imagine that you would hear what the objective measurements (and underlying electrical theory) show: higher impedance improves damping which Beyers generally benefit from. This ties in part to what you call 'loudness' (although in the DT770's case particularly, it has enclosure resonances as well). I am glad we see eye to eye on my dislike on this design. I generally found MD does (did?) a very great job at curation and this strikes me as a nasty misstep. More fundamentally: part of Beyer's core identity is a high impedance dynamic. . . I'm not aware of any other 600 ohm voice coils (?), certainly not in this price range. Their 600 ohms have phase uniformity like a planar, they really meet Dr. Beyer's original vision of a dynamic that competes with an electrostat. This drop is like spending years on an exclusive collaboration with Ferrari that turns out to be a scooter (Introducing the Ferrari F5x Go!)

I doubt they will be better. If you want a bit more refined sound (take the edge of booming bass) consider upgrading with a Lawton Mod kit. And if you like the sound, DON'T buy different pads, the several I've tried all destroy the sound.

I compared the 177X to them in my review and enjoyed them much more of the Ebony's. They have some technicalities the Fostex lacks and show much better control of the highs. Overall, they felt substantially more balanced, imaged better, and didn't sound as boxy/closed-in. They're also built substantially better which means a lot more since they're being aimed for portability.

You should also verify the pin diagram to verify it's wired correctly or it could give a hosts of issues. Just because it ends in a 4-pin doesn't necessarily mean they wired it correctly as you can still get SE out of a 4-pin plug if wired as such.

Much better. It's not even close. The COPs don't have the level of resolution or clean bass like the 177X. They're so much better balanced and better built. My COPs also have some awful cup resonance which the 177X do not have. They are better damped by a wide margin.

I honestly did not like the sound of the DT 1770's at all. I probably listened to them a day and sent back. The bass just sounded so off to me, it wasn't smooth at all. If they have resolved this problem with these cans then I'll be happy. Otherwise they're going to get sold.

I am curious if these come with a warranty? I know MD isn't a authorized Beyerdynamic retailer but then again this is special edition made just for MD which kinda makes them a Beyerdynamic retailer . Thought the page doesn't list any type of warranty details which according to the FAQ means the item only has 30 day return policy on it.
