I like the Sony MDR-XB500s. This set is very warm with tons of bass which suits my musical tastes very well.
The hard thing about choosing a quality set of headphones is every single brand and model seem to have their own unique sound signatures. Through tons of trial and error I've learned that my preference for headphones is "warm with lots of bass". This gives me the sound and experience I'm looking for.
I absolutely hate headphones that are described as neutral because they sound weak and way too bright for my personal tastes. I can't count the amount of money I've wasted over the years buying headphones that audiophiles claimed were top-of-the-line because the sound signature was neutral which is supposed to be the "Holy Grail" of sound signatures . Personally, I feel that the warm sounding tones of bass heavy headphones make my favorite music sound more natural and enjoyable. Maybe it's because I tend to be sensitive to high frequencies so a little treble and mid range seem to go a long way or maybe it's the fact that I just simply like a lot of bass in my music. Regardless of the reason, a warm sounding, bass heavy set of 'cans' is my weapon of choice when it comes to listening to my favorite tunes in private. Additionally, I like to "feel" the music and have come to depend on that sensation to complete my musical experience
(I also prop my feet up on the 10" subwoofer that sits under my desk in order to better fell the bass vibrations) so a set of headphones that vibrate my inner ear is a major plus.
After lots of wasted time and money I just accepted the fact that my personal tastes differ from many so-called headphone audiophiles. Whenever I'm in the market for a new set of 'cans' I automatically throw out any models that are described as "neutral" and give extra attention to models that are described as "bass heavy". Please understand that I'm not criticizing headphone audiophiles I'm just stating that my tastes are different from theirs. Rock on music lovers!
