Please, oh
PLEASE just don't consider any Sony models, especially the V700DJ. While they may be good for sub-$50 headphones, these things go for at least $100, more commonly for $120~$130. Overpriced and not all that great.
Hoever, there
is one headphone in the Sony lineup that is decent...the Sony V6 and Sony 7506. Both are the same headphone...the 7506 simply has a gold-plated plug to resist corrosion and is marketed towards the professional range, which is another "feature" which adds roughly $20 to the price
. The V6's cost about $60, but they were recently discontinued so it's tough to find them at that price, or even for a price less than the 7506's.
I've heard the Sennheiser 212's are quite good, considering their price range. Etymotic's are nice and their ER-4S model considered to be the best one of the best headphones (rather canalphones which means they actually go inside your ear) on the market...only $270!
I'd also recommend going to
HeadRoom (www.headphone.com), as they have a lot of good, accurate information and recommendations about all things headphone. Pretty good prices, and I hear their service is fantastic! This would be a good place to go read up a bit. You can also go to
Head-Fi...it's a forum with a bunch of geeks who are just as nutty with all things headphone, as some people are on here about computer equipment.
Hope this helps! <sigh> Back to work I go...
EDIT: It is quite universally known among audio circles that Bose is crap. Please read
this article before you consider buying Bose...I would much rather see you spend the same money on something much better.
