this is a question directed to any of the audio/headphone-experts on the forum. for the past year i've been using these with my iPod and MacBook. i also have a simple speaker system that i am pleased with. i used it alot in the summer but now that i am back in college i am rarely home to use it except as an alarm clock: there is a subwoofer too behind the pillow. the sound is nice the way they are placed and it blows away my crappy headphones... but that doesn't say alot. Budget: right now i have around $200 in my bank account for money that i can actually spend.i don't want to spend past what i have now ($200) and definitely no more than $100 of my next paycheck (poor college kid... some of you prob know how that goes) i want to figure out whatever is the best way to go as far as headphone setup for my lifestyle, my tastes in music, and unfortunately my budget. Musical Tastes - some of my favorite bands would be The Killers, Vampire Weekend, Animal Collective, MGMT, Sigur Ros, Muse, Keane, KiD CuDi, Coldplay, Radiohead, Fleet Floxes. i love rock, pop, electronic, rap, indie type bands, acoustic, dance, techno, soundtracks, (or mixes of them) i love music. the beatles to eminem to cascada to animal collective to the Gladiator soundtrack... ect... the only genre i don't listen to stuff from is mostly country, jazz, opera, and screamo/metal. indie rock and mainstream pop/r&b/electronic is my favorite stuff... Lifestyle & Listening Enviroments - i'll be using these when i'm at places like Panera Bread or Atlanta Bread Company working on homework or just on my laptop (will open headphones be too annoying to others in a cafe like this?). i'll be using these when i'm at home and don't feel like sitting on my bed. don't care to much about the size of these... Source - my MacBook w/ iTunes 9.something & Snow Leopard. my 2nd generation nano iPod. I also have a few Apple Lossless albums converted from FLAC or imported from CDs that are around 1000kbps per song. not sure if that helps... some my favorite CDs i put lossless copies in my iTunes... What i've looked at: I bought these skullcandy skullcrushers which i am planning on returning because from the research i've done, i haven't read anything that would suggest they are the way to go - even though i do like the adjustable bass... i liked the clarity for softer music of the $140 bose at best buy (which i've heard are way overpriced) much more than these, but those had no bass for the more electronic/bass intensive music. after researching and looking online: Sennheiser HD-595 Premier Headphone Sennheiser HD-555 Audiophile Headphones Sennheiser PXC 350 Active Noise Cancellation Headphone Sennheiser HD-515 Audiophile Headphones Sennheiser HD-280 Professional Headphones i've read good things about Sennheiser... open my world up? something with detailed sound quality while being able to deliver bass for electronic based music.... oh and i've read things about amps with headphones? i don't quite understand that topic. does that apply to me? is that like an external sound card? should i get something like this for best sound quality? please exploit your knowledge, experts of this subject. point my noobishness in the right direction based on my tastes and lifestyle.:smile_phones: i want to be sure if i am buying something online... i don't want to need to return it.
