Headphones that sound good without an amp
I am looking for my first pair of headphones, but don't want to spend extra money on an amp. I am looking for a pair less than $150 and got some suggestions like the AKG K371 and Sennheiser HD 560s, but not sure if they would need amps. I am only focused on hearing higher quality music from my computer or phone without the use of an amp. I have seen a lot of great things about the Sennheiser's, but have also read they lack bass, which could be a deal breaker for me because I love listening to the bass lines under the rock music I listen to. Please share some advice. Thanks!
