Query: Too Tight and not the best sound

I found the Sony MDR-V150 Headphones to be too tight for my head, and I believe many other reviewers share the same view as me. After 15-20 minutes of use, I had to remove them because of the growing pressure against my ears. I ended up with a splitting headache after I used these headphones. And what's more, the sound quality isn't that great either.And I'm not comparing these with in-ear iPod headphones. I'm comparing the Sony ones with on-ear headphones of other make. For example, I previously owned one made by Panasonic, and the sound quality was superb and it was very comfortable to have over your ears. Even the Bose on-ear regular headphones are comfortable and provide good quality sound, although those are a lot more expensive.
