Hello, this is my first post (and to be honest, I'm not sure if this is the right section, I wasn't sure if the banner for recommendations and whatnot was the right place to ask this, so bear with me please) and I'd like to ask a question about these headphones, or maybe other in this price range (£150, UK), but I've narrowed it down to these two. To make things clear, I wouldn't class myself as an audiophile, though I love music and have been lurking these forums for a while now. My main source/playback device for music is my HTC One X phone (international, so has a terrible built in DAC) but at the end of the month I'm upgrading to a Sony Xperia Z1 as I've heard good things about their built in DAC's (plus that SD card expansion for .FLACs, .WAVs and .AACs right?), I don't have a portable headphone amp, though I'm planning on buying one when I get my new phone. My main music file types are FLACs, WAVs and a lot of 320kb/s MP3's, I know lossy MP3's are a sin, but I just don't have the storage space at the moment to store all my favourite songs as lossless files. On to my dilemma, both of these headphones fit snugly in my budget, though I want to know if they will be better than Beats Mixr (my sisters, I promise). For starters I'll list my favorite artists :- Plus 44 KOAN Sound MitiS/Joe Torre Blink-182 Jamie T Kid Cudi I'm partial to a bit of Paramore The XX/Jamie XX Alexisonfire Bloc Party Enter Shikari Fall Out Boy Tonight Alive Zedd Yeah Yeah Yeahs Ellie Goulding I'm wondering which will be more suitable for my...variety of tastes, as far as I've researched, the ATH-AD900X's lack punchy bass which will be a big problem for me as I enjoy Liquid DnB, Chillstep and Glitchhop, but not the more generic dubstep genres. One final question, about Open headphones, I usually listen to music for 3-4 hours when I go to bed, but the rest of my fairly are in the adjacent rooms to mine, and I usually play my music at atleast 50% or higher volume, would the open/leaky nature of open headphones make this no longer possible? Thanks for advance for any help given, and if it's in the wrong section...please move or delete it.
