When you mean full size, do you mean the kind that completely cover your ears? In what environment do you use your headphones? Are you going to use them to just listen to music?
I think it's hard to go wrong with headphones from Grado or Sennheiser. I've listened to both, and thought they sounded great. I play in a band with a couple of geezers, so I bought a Sennheiser 280 Pro, which you can get for $100 or less, they have real even frequency response, and block out a lot of ambient noise. I use them for when we try to record, and it won't work miracles, like completely drowning out the drum set, but it lets you hear the headphones above everything else. They were made for DJ's, but they sound pretty good for just listening to music, too.
I also have a pair of
Shure ear phones, the kind that go inside your ear canal, and they actually block sound better than the Sennheisers. I've been wearing ear plugs when I play with the band for quite some time, so I don't even notice I have them in, but it may take a while to get accustomed to the feeling for others. You absolutely must get them to form a seal in your ear, using the directions found somewhere on the site, or else the bass is just pathetic. Once you do put them in right, though, they actually put out a decent amount of bass, and pretty much block out the outside world, so you don't have the turn up the volume at all. The Shure e2c is what I use to listen to TLLTS, and I love those things, but you'll probably get better bass from the more expensive models.
So, it depends on what kind you're looking for, but Sennheiser and Grado do very well with headphones, and I'm fond of the pair of Shure earphones I have. Hope that helps.
, and I'd like to get something really good sounding to replace 'em. Looking to spend between $100-200 bucks. You guys have any recommendations? I've been checking out the stuff at http://headphone.com, and I'd like some input from the TLLTS crew, or anyone else that has some knowledge about audio.
