They're awesome
Everything is amazing. It's like a big cushy movie theater seat, but on your head... Those ear pads are great and the closed back design does wonders for bass extension without a muddy sound.

Probably the best bang for the buck planar headphones
One of the best sounding headphones at this price point that I feel competes with sets that cost even twice as much or more in some cases. Just make sure you have a decent amp to pair with it if you want to extract the best sound from it, as it needs some extra power beyond what a computer or phone can provide. The bass response was also better than I expected and it's an enjoyable set for listening to music or using for video editing. It's also very comfortable overall and I like the unique design and color aesthetics. Definitely recommend for anyone looking to upgrade their headphones to something that hits above its price point and is a great higher quality option for the vast majority of people who aren't ready to break the bank with something much more expensive yet.

Solid build quality, clean low end
These sound clean, like really clean, especially in the midbass. "Semi-open" in this case means that they sound almost closed, but not a bad thing. Out of my ten sets of cans I don't think these sound quite like anything else I have. These things are thursty for power, so don't think that you can get away with plugging them into your phone or laptop, because you won't.

A great daily driver
I got these headphones to replace my Beyerdynamic 770 Pros that had issues with a loose wire. Other than the needing to boost the impedance from my amp, these headphones have been fantastic. The earpads are comfortable for long sessions and don't cause any fatigue when wearing them. On top of that, they have been a solid daily driver for me for the past two years. The headphones have been perfect for meetings on Teams and Discord, along with my lossless library, where the magic really shines through.

Amazing sound
These headphones sound amazing! You'll definitely need something that can provide enough power for these, otherwise you won't get a lot of sound out of them

The best bang for your buck*
I have had a few experiences where the expectation was so much less than the reality, that it left me speechless when I finally try it. These headphones are certainly one of those items. I was expecting a pair of $200 t50 mods to be very harsh like the stock ones. These exceed my expectations by a mile, other than the cable they feel higher quality than I was expecting. They sound absolutely superb especially considering the price. The only thing to note is that they do indeed require a significant amount of power to get the most out of. You can get 85-90% of the experience with a Schiit Magni Heresy and that is still worth it. I run them on an emotiva A2m and man do they sing. If you want good planar headphones and you are on a budget these are absolutely worth the price. They would he worth it at double the price, and not even the worst at triple.

Very fun headphone
A surprisingly competent set, with a tasteful and fun v shape sound. Has an very nice aesthetic and build as well. I wouldn't recommend it a someone first audiophile headphones; I would recommend something more balanced as a started headphones. But it is an excellent side grade to have for folks who already have experience in the hobby.

Good intro to planar
Love these headphones. The Dekoni mod makes them very comfortable and with a good eq they work fantastically. Can’t speak too technically because I’m just now getting into the hobby and still learning a lot. Listening to Tidal Master audio through UAD Apollo Twin Solo interface at the moment, stock cable. The interface is more than enough to drive these headphones. MacEQ offers an EQ preset for the Dekoni mod, plus balance and reverb settings available to get a slightly wider soundstage. The burn in period is a must, as it really opens up the clairty on the mids and lows for vox and bass. In the few weeks I have had them I have found that they are great for Rock, Indie, Hip-Hop, Folk, Pop (mostly 80s/New Wave) and still leave something to be desired for Classical, Funk, and EDM. Excellent for movies with high quality audio (hearing foley in a way that I never have before!), especially action movies and anything with a dynamic score/soundtrack, so I imagine they’d be great for gaming (minus the need for a mic). Audio listened to for review (Tidal Master):
  • The Strokes - The New Abnormal
  • Kendrick Lamar - Mr. Morale & the Big Steppers
  • Sufjan Stevens - Illinois
  • Sufjan Stevens - Carrie & Lowell
  • Jack White - Lazaretto
  • The White Stripes - Icky Thump
  • The Talking Heads - Speaking in Tongues
  • Prince - Purple Rain (Tidal Hifi, not Master)
  • Fleetwod Mac - Rumours (2001 Remaster)
  • The Arcs - Electrophonic Chronic
  • Tame Impala - The Slow Rush
  • The Smiths - The Queen Is Dead
  • Beyoncé - Lemonade
  • Skrillex - Recess
  • Daft Punk - Discovery
  • Yo-Yo Ma - Six Evolutions-Bach: Cello Suites
  • Herbie Hancock - Head Hunters
Video (various sources, all streaming):
  • Hunter x Hunter
  • The Blacklist
  • Interstellar
  • Ocean’s 8
  • The JHS Show (various 2020-2023 videos)
Will likely mod them using some of the guides out there, but for now, these are an incredible step up from my AKG371s, AirPod Pros, and Dunu Titan S IEMs in terms of overall comfort, build quality, and sound separation.
