Do You Need Some Piece And Quiet? You don’t have to go out of the city. Even if you are caught in traffic or in a crowded place, the HYZ Bluetooth headphones with the advanced noise cancelling technology will dampen any sound! All you have to do is put the wireless headphones on and flip a switch. And it’s done! You’ll be able to work, study, travel and sleep in complete silence. But, of course, you can also use the adjustable headphones to listen to music, watch your favorite movies or TV shows, play video games or answer your calls. Practical, isn’t it? Advanced Bluetooth Technology That Is Compatible With Most Devices! The active noise cancelling headphones work with a CSR Bluetooth chip that supports A2DP, AVRCP, HFP and HSP, and you can connect them with most – if not all – Bluetooth devices. Alternatively, you can get the 3.5mm aux cable that is included in the bundle and connect it to the adjustable over-ear headphones. Long-Lasting Comfort And Battery! The built-in 400mAh battery of the Bluetooth headphones is rechargeable, and it can charge fully within about 2 hours. After that, you will be able to use the wireless headphones for about 18 hours straight! And don’t worry, your ears and head will be fine. The high grade protein leather ear pads will be very soft on your ears and the adjustable headband will give you a secure and comfortable fit. Backed Up With A One Year Warranty! The package includes the over-ear headphone, a micro USB charging cable, a 3.5mm audio cable, a user manual, a compact carrying case and a 1-year warranty card. So for if you place an order now, for the next 12 months we will be able to fix or replace your Bluetooth headphones.
