jjsimp: I've had two different pairs of wireless headphones from Sennheiser...starting with the RS85 purchase in 2002 to my current wireless the RS140. All of them have great sound if you are in the same room as the bay station, but I can travel to almost every part of my house without losing complete audio. They get a little static as you move out of the room, but are usually clear once you stop walking.
Not sure how BT wireless will be, but with Sennheiser's name on it I'll purchase a set.

Edit: in case you missed my edit above...Amazon had better pictures of the 550X, so the link is up there.

Crosmando: The only headphones you'll ever need are good old Sony MDR-V6's

RedRagan: Looks good. But the price tag scare me away :p

jjsimp: Yeah, the price tag has kept it out my reach for quite a while now. I'm not sure if I will ever buy a set. They just hold most of the things that I require in headphones...Noise Canceling, Circumaural (not resting on the ears), and BT being the plus part. I could do without BT, but not the other two. And of course it has to sound decent, with no tinny highs, and no overdone bass, so with the last part I can rule out the Beats headphones.

Mnemon: Sennheiser HD380 pro (after having HD280 pro's previously) here. I like their flat return - no over-pronounced bass / treble. Clamp tight - which is how they keep sound out - but it doesn't bother me, personally. The HD 380 with the larger earpieces spread out the pressure a lot more than the HD280, but I could - and have - worn both for prolonged time. Both are reasonably priced. The hardcase that comes with the HD380 is nice - packs them flat and more secure.

That said - I had both fail on me. The HD280pro's left speaker went, completely, a few years after warranty had run out - I'll get those repaired if I have some spare cash. With the HD380 pro the left speaker stopped working intermittently until I unplugged and re-plugged, once in a while; got that one repaired in warranty; took about a week and is fine since. By and large they are considered to be pretty rugged (and most parts, except for the internals, are easy to exchange) - I just seem to have gotten a bit unlucky.

They are ugly though. If you are into aesthetics they aren't for you.

Edit: Now with links.

Crosmando: MDR-V6's are very solid and quality in my opinion, I have had mine for about 7 years now and they are still fine, no noticeable degradation of output, I have replaced the the ear pad things a few times but that's it.

EDIT: And yes they are very sensitive (they are studio monitors after all), and you can notice the diff between FLAC and MP3, between 192 and 320 kbps etc.

haydenaurion: Would you recommend the MDR-V6 or for gaming? Your recommendation of the MDR-V6 seems a good choice, but i'm leaning toward the MDR7506 as [url=http://reviews.cnet.com/headphones/sony-mdrv6/4505-7877_7-31248927.html]this review states that the MDR7506 sounds a bit more crisp with less bass which I think I would prefer.

Crosmando: I really have no idea as I've never used a pair of 7506's, but seeing as they're the same basic model I cannot imagine the difference is that noticeable.

RedRagan: Actually they are pretty much the same! the only difference is that the MDR-V6 version can be considered the "compact version" since you can "fold" it and carry it around with a carrying bag. The MDR7506 is the "fixed" version where you can't fold it.

Also becareful of fakes. Demands for those two are big enough to make people actually made bootlegged version of them. They are pretty damn convincing too. Need a lot of time for me to make sure that my version of MDR-V6 is the legit one.

senbon: If you are looking for a closed headset I recommend Beyerdynamic DT 770. I've been using the 80 Ω version for a few years now, and they have yet to let me down. Depending on the Ω you might want to also acquire a sound card.
