I work at a computer and have my headphones off and on all day long. I've always just used apple earbuds and junk like that, but I'd like to take a big step up.
I'd like to stay under $200 USD. I'm pretty sure I want open, not sealed.(correct me if I'm wrong) I do need to hear people that walk up to me to ask questions and hear the phone ring and what not. I don't listen to music at a super high volume. I'm not concerned about people around me hearing the music leak out at all even though we work in a fairly quiet environment.
I listen to a wide variety of music. Lots of rock such as Muse & The Killers up to Metallica. On the flip side, I listen to a lot of acoustic music as well. I play bass in a bluegrass band. I love listening to classical/spanish guitar and even full fledged classical music. And every now and then some techno/dance/electronica.
So far I've been thinking the Phillips L1, but people say it's really warm and bass heavy. I'm also looking at the Sennheiser HD 598.
Yell at me if I didn't include any key information. Again, I'm a total noob here and trying to learn!
Also, browsing around I've seen tons of references about portable amps. I never knew such a thing existed... Please educate me on the need for these if they're important to my situation. I'll just be plugged into my work computer or iphone 5
