Bose QuietComfort Ultra Wireless Earbuds, Blue

The Bose QuietComfort Ultra are true wireless earbuds designed for audio playback and voice calls. They connect to devices using Bluetooth 5.3 and feature an in-ear design intended to create a seal within the ear canal. For a secure and stable fit during use, the earbuds are supplied with three sizes of soft silicone ear tips and stability bands. The audio system incorporates sound personalization technology, which measures the acoustic properties of the user's ear to tailor the sound profile, and includes spatial audio processing to create a wider soundstage.

These earbuds are equipped with adjustable active noise cancellation to reduce ambient sounds. The built-in microphones feature noise-reduction technology for clearer voice transmission during calls. On-earbud touch controls allow for management of playback, volume, and call functions. The battery provides up to 6 hours of continuous use, and the included charging case extends the total playback time to 24 hours. A 20-minute fast charge provides additional listening time, while a full recharge takes 2 hours via the USB-C port. The construction is rated IPX4 for resistance to sweat and water splashes.
