After this week is over it's back to the dorms with me. I'd like to be able to get a set of headphones so that I can listen to music on both my laptop (what I'm typing on now, a powerbook) and my PC back at the dorms. Also, since I'm now a poor college student after buying this laptop, I'd like to spend under $50 on the headphones. I've been browsing bestbuy.com and I've seen two Sennheiser headphones for under $50- the HD477's and HD457's. Are these good headphones? I'd probably go for the HD477's. Also, will they be fine volume wise both out of my laptop's headphone jack and my PC's line-out jack? Would you guys prefer some other set of headphones? Main emphasis is going to be movies, games, and music... so pretty much everything. I know I can't exactly get sweet, kick-ass headphones for $50, but I need some sort of decent headphones. I CANNOT spend any higher than $50 ($55-60 including tax) so please no "if you're willing to spend a bit more..." replies.
