Headphone Recommendation?

I'm with Todd. www.head-fi.org is the place to go for this question, not that I would discourage headphone-talk over here. I've kind of gone off the deep ends with the headphone / headphone amp / replacements cables end of this fine hobby, but it has been a great journey.

All of the above is true. To get your feet wet, you probably can't go wrong with either the Senn HD-600s if you like a little more laid back sound, or a high end Grado if you want a more forward sound. Either one will want a good amp like a Maxed out home or Grado. Or maybe Stax Electrostats if you can handle the freight. As Bill said, you can go overboard here as well. Hi, my name is Michael and I am a headphone-oholic!!! Have fun.

Senheiser HD 600 or Grado RS-1 with Musical Fidelity V3 Headphone amplifier.

I'd avoid wireless headphones. If you do get a nice pair of wired headphones, you may want to consider getting a dedicated headphone amp. I like the Grado RS1s. I had the Sennheiser HD600s and they were too laid back. I also had the Stax Omega II/SR007t combo and that was breathtaking but that combo may cost more than you're looking for. With the Grados I am using an Emmeline XP7 headphone amp.

I have the Sennheiser HD580's and I love them. Got them from a dealer who advertizes here on Audiogon for $159 [new], which is the best deal I've found. The 600's sound a little bit better, but they are quite a bit more expensive, although the same dealer lists the 600's at $259, which is also the best deal I've seen. I ordered several sets of the 580's and they were shipped promptly, arrived in perfect shape, etc. I gave some of them away as gifts and everyone loves them, can't believe the quality,
etc. I don't use an amplifier and don't really feel the need. I put the bulk
of my money into my main system, so I don't want to get too deep into the headphone thing -- I just want a pair that sound great without much trouble and the 580's fit the bill perfectly. Plugged into my system, a computer, or an ipod, they go plenty loud and -- sound REALLY, REALLY,
REALLY good. IMO, you'll have to spend quite a bit of money to outdo
the 580's. If you are game, though -- listen to the 600's and the more
expensive Grados.
