Fitment: The pictures may them look bigger than they actually are. I have an average size head and they fit fairly snug. The ear cups are not that big either but my ears do fit in them albeit barely. However, even with those issues I have not had any fatigue wearing them for ~3 hours straight. Features: Bluetooth connects and disconnects without issues. I have yet to try the music share function. I do like the google assistant integration as you can nearly leave the phone in your pocket or bag the entire time and still get all your notifications, make phone calls, and send text messages. The button layout and design is slightly odd. I wish the bluetooth and share buttons were more differentiated from the volume/play buttons as I sometimes mix them up. The power button is a slider so you can't accidentally hit the power button. If you run out of juice, there is a headphone jack for you to directly connect. However, the headphone side is the smaller 2.5mm jack while the phone side is 3.5mm. I find this strange as it make it more difficult to replace the cable if/when it breaks. Sound: Music is very accurate. The highs and mids are powerful enough but the low end bass is lacking. Because they are JBL's, I was hoping for a bit more punch in the low end without having to run a secondary EQ app.

The sound is very low, I received the headphone with scratches and the headphone fall off al the time

Bought this for Christmas and couldn't wait for my husband to try them out. He loves these headphones! Thank you JBL!
