Bose QuietComfort Ultra Earbuds

CustomTune technology sends a chime into your ear canal to measure its unique shape. It then calibrates the audio performance to match your specific anatomy, ensuring the sound profile is optimized for your ears rather than a generic listener.

Yes, the earbuds feature noise-rejecting microphones designed to isolate your voice from background interference. This makes them effective for taking calls in busy offices, cafes, or while commuting.

Standard mode provides a balanced, direct sound profile. Immersive Audio uses spatial processing to create a wider, more expansive soundstage that makes music feel like it is coming from speakers in front of you rather than directly inside your head.

The earbuds come with nine different combinations of eartips and stability bands. We recommend testing different sizes for both the tip and the band to find the seal and grip that feels most secure without causing pressure during long listening sessions.

Yes, Bluetooth multipoint lets you pair the earbuds with two devices simultaneously. This allows you to seamlessly switch from watching a video on your tablet to answering a call on your phone without manually disconnecting and reconnecting.

ActiveSense monitors your environment and automatically adjusts the noise cancellation levels. When it detects a sudden, loud sound, it softens the spike to prevent it from being jarring, keeping your listening experience consistent.
