Bose QuietComfort Ultra Earbuds (2nd Gen)

Name: Bose QuietComfort Ultra Earbuds (2nd Gen)
Brand: Bose
SKU: 1308

Manufacturer: Bose

The Bose QuietComfort Ultra Earbuds (2nd Gen) are a fully wireless in-ear option in the wireless earbuds category, built around a compact, cable-free design that weighs just 15.4 g per earbud. They carry an IPX4 sweat-resistance rating, making them suitable for active use, and come with a charging case that extends total listening time to 24 hours combined. A travel bag is included in the box, and the earbuds support multipoint connection to two devices simultaneously.

On the connectivity side, the earbuds run Bluetooth 5.3 with aptX Adaptive and AAC codec support, covering a maximum wireless range of 10 m. A 9.3 mm driver handles a frequency range of 20 Hz to 20,000 Hz, while active noise cancellation works alongside passive noise isolation for additional sound blocking. The eight-microphone array includes noise-canceling microphone technology for calls, and the earbuds also offer an ambient sound mode, fast charging with a one-hour full charge time, and wireless charging support via the case.

Pros

Active noise cancellation is paired with passive noise reduction, providing two layers of sound isolation
An 8-microphone array with noise-canceling technology supports clearer call quality
Multipoint connection allows simultaneous pairing with two devices, useful for switching between a phone and laptop
Wireless charging on the case removes the need for a cable when topping up
A find device feature helps locate misplaced earbuds
Ambient sound mode lets external audio through without removing the earbuds

Cons

Total battery life of 24 hours combined is on the shorter side for true wireless earbuds in this category
No fast pairing support means the initial connection process requires manual steps
Wingtips are not included, which may affect fit stability during physical activity for some users
Spatial audio is not supported, limiting immersive audio experiences for compatible content
The 10 m maximum Bluetooth range is relatively short for a wireless product

Who is this for?

These earbuds are a practical fit for commuters, office workers, and anyone who regularly needs to tune out background noise, thanks to the combination of active noise cancellation and passive noise reduction. The IPX4 sweat resistance and true wireless design make them workable for light to moderate workouts, while multipoint connectivity suits users who switch frequently between two devices such as a phone and a laptop. The included travel bag, ambient sound mode, and find device feature add day-to-day convenience for people who use earbuds on the go.

Who is this NOT for?

Users who need extended listening sessions without access to a charging point may find the 6-hour earbud battery life limiting, particularly during long flights or travel days. Those who rely on spatial audio or immersive surround formats for gaming or cinematic content will find the lack of spatial audio support a notable gap. Additionally, users who prioritize a secure, sport-focused fit may be underwhelmed since wingtips are not included, and the design offers no enhanced stability features for high-intensity physical activity.
