Bose wired earbuds fix ANC without battery

Bose has launched new $99 USB-C wired earbuds that bring active noise cancellation without needing a battery. The earbuds draw power directly from your device and support lossless playback with output fixed at 24-bit/48k Hz.

Bose offers Quiet, Aware, and ANC Off modes, with an inline remote for playback, volume, calls, and ANC controls. There's no requirement to use an app, and since the earbuds draw power directly from the connected device, there's no battery to charge either.

The earbuds use Bose's proprietary Sound Design digital signal processing technology to deliver crisp and clear audio, alongside support for lossless audio playback. They support the USB Audio Class 2 protocol and have dedicated microphones for reducing unwanted noise.

The Bose Noise Cancelling Wired Earbuds come with soft silicone ear tips and are rated IPX4 for water resistance. They will be available in Black, White Smoke, and a limited-edition Dewdrop Mint colorway, with pre-orders starting through Bose and Best Buy and shipping beginning on October 15.
