Hi, amplifier's sound is a problem for my roommate so i want to buy headphones but i don't know what kind to buy. Will normal headphones with a converter piece be as good as headphones with jack input?

What are you plugging them into? A line out is not the same as a headphone jack.

Sennheiser's are a solid choice and AKG aint to bad either.

Personally I think these will give you the most bang for your buck, they will sound great no matter what as long as you got the juice to drive them. (which isn't to much)

before you buy headphones make sure you amp has a headphone out
cause if you just plug into the output of the amp youll most likely fry your headphones and maybe damame your amp
