The first thing I noticed was the build quality. They feel very premium and durable. The ear pads, headband pad, and cable are all replaceable and I believe more parts can be replaced as well. The packaging was also nice, everything was cardboard and paper and nothing was plastic. It comes with 2 nice cables, one about 6ft and the other about 10ft, as well as 6.35 mm (1/4 Inch) adapters for each cable.The next thing I noticed was the comfort. The pads are super soft and plush, but the clamping force of the headphones is surprisingly strong. I could see some people thinking it's too strong, but I personally think it's fine. It's either loosened up or if just gotten used to it, but it's still noticeable. It doesn't really bother me personally though but it's worth mentioning.When I first started listening to these I was immediately blown away by them. I also have the Philips SHP9500 and the Tribit Xfree Tune. Both of those are decent headphones but these were an obvious improvement over both in my opinion. I'm not great at describing sound, but these seem to be fairly neutral with a slight emphasis on the low end. That's not to say they lack bass though. If the song itself has some bass to it, that will absolutely come through on these, just in a very clean way that doesn't detract from the mids or the highs. So with that being said if all you want is bass and as much of it as possible these probably aren't for you. To me they've sounded great for every genre I've tried, but I generally listen to a wide range of rock music. They're also good for movies although I haven't used them much for that. I also really like them for gaming. Being detailed and somewhat neutral I find it easy to pinpoint where things like footsteps are coming from. They also can be powered from anything. I've used a usb dongle dac, a vintage stereo, and an Xbox One controller and it sounded great through all of them. I love the sound of theses, they're absolutely just going to replace my existing headphones for literally every use case.If I had any complaints, it would be the clamping force even though as I said above it doesn't really bother me. I'd still prefer if it wasn't as tight and I could see it being a problem for some people. I may update this review later on if they loosen up some more.My only other complaint is with the cables. The connector is kind of long sticking out if the headphones, it's enough that it can touch my shoulder sometimes. It's especially noticeable if I'm wearing a hoodie.Overall I really like these headphones. They're maybe a bit too expensive, but I think they sound fantastic and by the looks of them they should outlive me so I'm very happy with I got here.1 Month Update:Just an update after using these for a month. I still really love them. The clamping force is still tight, although it's either loosened up or I'm just a lot more used to them now, but I find them to be more comfortable now.6 Month Update:Yeah I still absolutely love these headphones. They're even more comfortable now, the clamping force has gone way down. I would pull them apart a bit to loosen them up, and from that and just wearing them a lot it's not nearly as tight, although still has some clamping force to it.. it's just right now in my opinion.
