The comfort is average at best, and the treble is very recessed. This makes music lack detail and sound muddy. I tried equalizing the sound and it's still bad. Avoid this pair of headphones if you listen to treble-heavy music like rock. However, they look good and have good Bluetooth range and battery life.
EDIT: don't buy from Big Father. He is a scammer who never delivers. I bought from him (also goes by the name Black Crystal LLC) another headset and he didn't deliver it.
