[Stereo] Managed to nab the emerald editions and they look as fantastic as they sound. Coming from Audeze LCD2s which are great as well but just uncomfortable for longer listening sessions. The TH900mk2s are lightweight in comparison and very comfortable. I also needed a closed back design for listening at night when the wife is asleep but didnt want to compromise sound quality, and these dont disappoint. Soundstage is still good, smooth across the lows/mids/highs, doesnt seem to be missing or lacking anywhere. I expect to enjoy these for a long time to come.

[1.25 lb] I got them a week ago and man this headphones pack a punch. I really wanted to try open-back style headphones for the experience so I went with these and I don't regret it. Best sound I've got from headphones under $$. Don't expect a bass that will make your head shake, these are open-back, they wont provide you with that kind of bass. They'll give you a DEEP BASS experience, meaning that the bass will sound clear, deep and powerful yet detailed. A bass that will make the music sound full without making you feel like you have a boom box stuck in your ear. The clarity of these it's a great thing. You can identify things you didn't know were in your songs. I have played classical, jazz, rock, metal, hardcore, trap, almost any genre I could think of and these babies delivered. If you have a good player that support FLAC files, prepare to be amazed by the T20RP's. They sound so good that you will start noticing how bad some music out there has been produced. They have a bit of a high impedance so I'll have to get a portable amplifier to take them to another level. They also look cool, some people may not like the look of them but I find it rad.

[Dynamic] HD800 owner here, TH900 best kept secret in high-end headphones. Gave the HD800s to the wife!

[Dynamic] great head-phone! If you listen to hiphop,r&b or any music in general, you need this. Bass is deep, both mids and highs are great. Headphone works ok with your mobile devices, but you will ge greatly rewarded if you power this with a amp.

[50 Ohms] Pros: The best compliment I can pay these are this: When I listen to music on them, I have yet to wish for more treble or bass or vocal clarity. They disappear on my head and I can just truly enjoy what I'm listening to. For the price, especially compared to the cost of other planar headphones, that is epic. Cons: I would suggest watching Z Reviews' Youtube video on all of the Mk3 headphones to get an idea on the differences and comfort mods between the three. (https://youtu.be/SpRCK6CVdis - Children beware, there is swearing in the video.) I think his review is spot on, in just about every aspect of this. (Disclaimer: I haven't heard the 40RPs, just the 20's and 50's.) First Con: The stock earpads. They are super thin, and not very comfortable - but to be honest, not hurtful. They are essentially ON-EAR headphones with the stock pads, as your earlobes will make contact with the inner driver area. The Shure HPAEC1540 and 1840 pads are hands down the most comfortable and best sounding pads I've found for the T20RPs. I like the 1840 pads just a bit more than the 1540. Second Con: The headband is thinly padded. It isn't uncomfortable, but can be improved upon. I went with the Mr. Speakers leather headband, and they just float on my head now. No pressure points becoming sore after hours of listening. The hardest part of installing this was figuring out where in the house I left my screwdriver. Third Con: Sensitivity. These are not easy to drive. Your smartphone will not suffice. If you need an inexpensive amp, I suggest the Micca OriGen+, or one of the many Fiio products. I listen to mostly rock, classic rock, metal, edm, blues, and a limited number of jazz and classical tracks. I would describe my listening preferences as being 1/2 way between bass-head and audiophile. I love bass, want it loud, but do not want it trampling over the rest of the music. I purchased the T20RP Mk3.

[Closed-Back] What to say, I love them in every way and can’t Waite for the Anniversary Blue Sapphire which I’ve already ordered and paid for through B&H. I also love B&H

[9 x 7.4 x 4.1"] My application isn't super demanding but we needed a way to hear our broadcast better in our media room. Unit did everything I wanted it to. Love that it is rackable. Was more than loud enough for my application.

[Stereo] The sound on this isn't dissipointing at all! Very wide range, clear and is loud enough for busy environments. I'm using in a Mobil production HD fly pack and love it. Worth every cent.
