JVC HA-M555X. 50$.
Bass:10 (I'd rate more if I could for bass. Absolutely ridiculous. Better than anything under 400$.)
Isolation:8.5 on low volume. 5 on medium. 1 on loud... And by loud, I mean LOUD. Hook an amp, and they make the HTC One speakers sound as quiet as ear buds. And THEY DONT DISTORT.
Looks:7.5 because the flashy look isn't for everyone.
Build Quality:8.5 Based on a scale of dysfunctional 50 cent headphones to V-Moda. The material they are made of is slightly cheap feeling, but not so much as to make you question quality. They are very nicely built, and can stand a few drops, and have a thick rubber cord, and rubber deep bass port protectors with the XX logo on it.
Comfort:10 Very squishy foam headband, and nice fake leather earpads. I've worn them for 12 hours straight on a music marathon and experienced no discomfort. Doesn't touch any part of your ears.
Portability: 5.5 Quite large. 11oz.
Value:10 They would be the best for under 400$, but that title belongs to its big brother, the HA-MR77X. Only headphones that are possibly better than these. If you want to spend 50$ more, the Ha-MR77X's are made of high quality plastic and metal, look better, have 57mm drivers, same deep bass ports, better sounding treble, and more portable since they fold up. The HA-MR77X's are 100$. Well worth it. Best headphones for bass under 800$ out of Sony, vmoda, Bose, sennheiser, audio technicas, skull candies, beats, sol republics, denon and more. Get an amp with those, and two words: BASS CANNON. Score for M55X:8.75
Score for MR77X:10
