I have been investigating the purchase of a set of closed full-size headphones for about a month. I really enjoy reading all the information available on this site. I have also been reading Tyll's really helpful site and have found that very helpful as well. Just as a caveat, I'm pretty new to all this!
I started my headphone research with a purchase of the Sennheiser Momentum's. I enjoyed the sound but the fit just wasn't right for me. After an hour or so, they hurt my ears. I always felt like my ears were being squashed inside the ear cups. The sound was nice and warm though I would have preferred a little more treble emphasis - not brassy mind you just a very small, smidgen more. They are in my price range $200 - $400.00
I have returned the Momentum's because of the fit (or lack thereof!) and now I'm trying out the Logitech UE6000. Much more comfortable! I don't think the sound is as nice as the Momentum's. I haven't done any appreciable burn in, just listened to them for about 5-10 hours so far. I feel that the sound in passive mode is a little flat and lacks oomph...I know - very technical. Also, the build quality is not nearly as nice as the Momentum's. In fact I had the whole force the cable into the female end of the phones problem. They just aren't as convincing a can as the Momentum's. Also, the UE6000 hurts the top of my head a little bit after I wear them for a few hours.
I have taken my iPad with some music to demo to Best Buy to try out the AKG K550. I really like that headphone! Sounds wonderful and I certainly like the "sound stage" which seems much more open to me than either the Momentum's or the UE6000. So I guess I like the AKG sound?!? Also, the AKG K550 is very comfortable and it seems to be really well built.
I don't plan on using the headphones I will be getting outside or for travel, though I could, it's just not a priority.I also really don't care about a control for the iPad or an iPhone.
I plan to have the phones connected to either my MacPro or to an iPad which hold my iTunes collection of Apple Lossless tunes that I have ripped from a CD library.
I listen to many, many different types of music but no hip-hop, rap. A little bit of electronica, some classical, lots of piano, classical and jazz (Bill Evans, Alan Broadbent) and I particularly like indie female vocalists in a folk vein, (Hem, Kathleen Edwards, Joni Mitchell, etc.) some country though not much, mostly "classical" country - Waylon Jennings, Dolly Parton, Jerry Jeff Walker. I'm also big into Neil Young, some blues, and some R & B and have been trying different phones (like the AKG K550 at Best Buy) with early Cat Stevens, some classical and a few other test songs and albums. I definitely am not a bass head!
On my short list currently is the AKG K550. I am still giving the Logitech UE6000 a chance, I'm just not thrilled - to me, the UE6000 just sounds a bit flat and lifeless in passive mode and way overblown in NC mode. Also, the cord is too short and sorta' ugly.
I am also interested in the AKG K267 except they are not that available and certainly haven't been reviewed extensively. Comfort is important and one thing I like about the AKG K550's is the long cord.
Currently, I would like a set of cans that don't need an amp, though I would be open to getting one down the road. That way I can use the headphones I eventually purchase with my iPad without having to have an external DAC, headphone amp.
I hope I have spelled out a little bit about what I hope to get in a new headphone.
Any thoughts, comments or suggestions?
TIA
