Love these headphones. I ordered them instead of another popular brand was said to be very uncomfortable and I wanted something with lots of bass as I listen to hip-hop/rap exclusively.Comfort-Very comfortable, they made my ears hot at first but they don’t anymore. I’ve been wearing them 5-6 hours a day with no problem.Sound-I’m not a audiophile so I can’t be very technical about mids and treble and stuff but I can say they sound great and have PLENTY of bass, it can be adjusted to have even more bass. Great for rap songs.Battery Life-Haven’t tested these too much yet. They arrived 70% charged and I used them all day and they only went down to 50%. Charged them for about 1.5 hours and they were at 100%. Will update later after testing fully.Durability-Can’t speak on this yet as I’ve only had them a few days but if they’re anything like my cheaper Sony headphones they should last a long time. I will update in a few months.Wireless Range-Another thing I haven’t tested fully but I can leave my tablet on the couch and go out on the porch or to my room which is 35-40 feet. No quality drop or interruptions.Noise Cancellation-These are not ANC headphones but they do block out most sound like people talking or watching TV in the same room.Overall I love these headphones so far. Super glad I chose them over the $130 competitors.Also you can tap the power button once when on and it will tell you the battery percent.
