Stream your favorite music right from your mobile device with these JBL EVEREST 700 V700BTGRY over-the-ear headphones, which feature Bluetooth 4.1 technology for simple pairing. JBL Pro Audio Sound with 40mm drivers delivers rich, immersive sound.
So I have had these headphones for about a month now. They are indeed the loudest over the ear headphones I have tried yet. Have not even gotten down to the low battery yet, claims 25 hours or so, pretty confident it is close to it. The button set up could be better. Too easy to try and sink with anyone jbl products. Also, the Bluetooth with anything besides music is actually really poor. Synced with my tablet to play games and watch Netflix, and there is a good delay for over a second. So these are good for just listening to music yet if you are going to use them for the, talking or tablets, I'd say find something else.
