Bose QuietComfort Ultra Earbuds (2nd Gen) - Black

Product Description:

The Bose QuietComfort Ultra Earbuds (2nd Gen) are Bose's flagship true wireless noise-cancelling earbuds — the absolute best noise cancellation, sound quality, and spatial audio Bose has ever put into an earbud, now refined with ActiveSense adaptive ANC technology, CustomTune ear profiling, and aptX Lossless wireless support. Every feature Bose makes for in-ear listening lives in this product: TrueSpatial Immersive Audio that places sound in front of you like speakers in a room, CustomTune that adapts audio and ANC to the unique shape of your ears, and the deepest noise cancellation of any Bose earbud — delivering a listening experience that separates the QC Ultra Earbuds from everything else in the true wireless category.

CustomTune™ fires a brief calibration tone each time you insert the earbuds, analyzing the acoustic response of your individual ear canal in milliseconds and automatically adjusting both the EQ and the noise-cancellation profile to match. The result is sound that's optimized for your anatomy — deeper bass where your ears naturally lose it, clearer highs where your canal shape attenuates them, and noise cancellation that's calibrated to the exact seal your ear tips create. No two people hear these earbuds the same way, because no two people have the same ears.

ActiveSense™ is the 2nd Gen's upgrade to Bose's noise-cancellation intelligence. In Aware mode, ActiveSense automatically detects and smooths sudden spikes in ambient sound — a car horn, a jackhammer, a subway screech — reducing them before they reach your ears without blocking the steady environmental sounds you need to hear. The result is a transparency mode that's actually comfortable to use in unpredictable environments, not one that amplifies every startling noise alongside the conversation you want to hear.

Three listening modes cover every scenario: Quiet mode delivers Bose's best in-ear ANC for maximum isolation — reducing 85% of external noise according to independent testing. Aware mode lets environmental sound through with ActiveSense spike protection. Immersion mode combines noise cancellation with Bose Immersive Audio, engaging TrueSpatial spatial processing that takes the music out of your head and places it in front of you in a virtual speaker arrangement — creating the natural, open, speaker-like listening experience that headphones traditionally cannot replicate.

Bluetooth connectivity is flagship-grade: Snapdragon Sound certification with aptX Adaptive including aptX Lossless for wireless hi-res streaming up to 24-bit/96kHz from compatible Android sources. SBC and AAC codecs ensure universal compatibility with all devices. Multipoint connects to two devices simultaneously. IPX4 water and sweat resistance covers workouts, commutes, and rain.

The wireless charging case holds three additional full charges for up to 30 hours of total listening time (6 hours per earbud charge in Quiet/Aware, 4 hours with Immersive Audio). Charge via USB-C cable or any Qi wireless pad. Nine fit combinations — three ear tip sizes times three stability band sizes — ensure a secure, comfortable seal for every ear shape. Touch controls on each earbud handle playback, volume, calls, and mode switching with customizable gestures. Available in Black, White, Desert Gold, and Midnight Violet.
