The battery lasts forever and the noise cancellation and sound quality is really great! The noise cancelling works really well. They have average sound, pretty good battery life, passive noise canceling.

Perfect blend of size and functionality. I am not an expert on audio but for a casual person that loves to listen to music, watch movies and play videogames this work great.

They charge extremely fast in the case, 5 minutes spent charging gives you about a hour more of use. Also they are very durable. The tap to touch is really useful when you are busy with your hands.

The oval case falls out of your pocket, and goes skidding cross the floor. Headphones skid across the floor and disappear in your seat.

Software is bluetooth bloatware. Ringing when bluetooth is connected. Turn off, turn on, reset, repeat.

Don't waste $100 usd on these pos's. They are just not functional, and for the price, it's a cash grab, riding on a brand name and not investing in r and d.
