Active noise cancellation, Bose Immersive Audio support.

Top in-ear TWS earbuds from the reputable audio brand Bose. The headset has a memorable appearance, offering high-quality sound and excellent noise cancellation. But let's go through everything in order. The model stands out with its vibrant look compared to the multitude of other TWS earbuds. As for the "internals," it features traditional dynamic drivers covering the frequency spectrum from 20 Hz to 20 kHz.

The "highlight" of the sound is the support for Bose Immersive Audio spatial audio technology, which operates in two modes: Still and Motion. The earbuds are also equipped with CustomTune calibration and the Bose Aware mode with ActiveSense, which automatically adjusts the intensity of active noise cancellation. The model quickly pairs with audio sources via Google Fast Pair. The average battery life of the Bose QuietComfort Ultra Earbuds is approximately 6 hours of audio playback. The case for the TWS headset charges through a USB type C port. Each earbud includes touch controls and basic water resistance rated at IPX4.

Perfect Fit

The premium TWS earbuds Bose QuietComfort Ultra Earbuds impress with thoughtful ergonomics. Although they are in-ear type, a comfortable fit is provided not by deep insertion but by a special design of the casing. The set includes replaceable silicone ear tips of different sizes and additional stabilizing attachments (“fins”), which guarantee secure fixation without pressure on the ears. Thanks to this, the model is suitable for workouts and an active lifestyle, and the IPX4 protection will keep out moisture and sweat.

Great Noise Cancellation

The active noise cancellation system is based on proprietary ActiveSense and CustomTune technologies. It allows flexible adjustment of the ANC level—from complete suppression of external sounds (the "quiet" mode) to a transparent mode, providing natural perception of the surrounding environment. The noise cancellation efficiency of the Bose QuietComfort Ultra Earbuds is considered one of the best in their class: the earbuds effectively cope with city background noise, transport hum, and office noise. The microphones are also equipped with their own noise cancellation, improving voice communication quality and reducing wind impact.

Benchmark Sound

Dynamic drivers deliver balanced and detailed sound with clear highs and rich lows. The distortion level is minimal even at high volumes, and touch control allows convenient volume and playback mode changes. The sound quality of the model is rightfully considered a benchmark in the premium TWS earbuds category.

The support for Google Fast Pair ensures instant connection to Android devices, and the Multipoint feature allows switching between two sound sources without delays. The autonomy reaches about 6 hours without the case, and the case provides several additional charging cycles. Full energy recovery via USB-C takes about 2 hours. Bose QuietComfort Ultra Earbuds are expensive but rightfully among the best earbuds with outstanding noise cancellation and impeccable sound.
