[Easy Plug & Go] When the Aria 90B is used on your PC, there’s no need to go through the complex Bluetooth pairing procedure; simply plug the adapter into your PC’s USB port, power on the headphones and you should be good to go. It works on Windows, Mac, Chromebook and any USB port that outputs audio. [Extended Mic] The Avantree 90B Headset comes with a long detachable microphone that’s placed near your mouth. Due to the close proximity, the microphone will be able to pick up your voice more clearly while effectively eliminating the excessive noise around you, no matter where you’re at. [Noise Cancellation] Like all other Aria Series headphones, the 90B features advanced built-in Active Noise Cancellation technology. When used in environments filled with low frequency ambient noises such as Air Travel, Subway and Bus Commutes, the ANC technology can block the noise out, giving you more peace & quietness. [Bluetooth 5.0] The Avantree Aria 90B is equipped with the Bluetooth v5.0 chipset, ensuring a more robust yet more stable connection; more audio quality, less breaking up. Need to walk around the house? No problem, do whatever you need to do, the reliable Bluetooth 5 will keep you connected. [Durable & Comfortable] The headphone runs up to 35 hours on each full charge (60% volume) so you rarely have to worry about the battery level. The lightweight (only 8oz) design along with the replaceable memory foam soft earpads will provide you with the comfort you need during your long-hour binge watching sessions.
