The Bose QuietComfort Earbuds (2nd Gen) use an in-ear fit and come with wingtips included to help keep them in place during use. They are true wireless earbuds, meaning there are no cables or neckband involved. Weighing 17 g, the earbuds carry an IPX4 rating and are sweat resistant, making them suitable for physical activity. Each earbud houses a stereo speaker, while features such as RGB lighting, a UV light, and a display are not part of the design.
The earbuds support both active noise cancellation (ANC) and passive noise reduction, providing two layers of sound isolation during use. The frequency response spans the full audible range from 20 Hz to 20,000 Hz. Spatial audio, Dolby Atmos, and Dirac Virtuo are not supported, and the drivers do not use a neodymium magnet.
The earbuds offer 8.5 hours of battery life on a single charge, with the charging case providing an additional 23 hours for a combined total of 31.5 hours. A full charge takes 1.5 hours via the wired connection, as wireless charging is not supported. The battery is rechargeable, and a battery level indicator is included, while solar charging is not a feature of this product.
The earbuds connect wirelessly via Bluetooth 5.3 with a maximum range of 9 meters, and USB Type-C is available for wired charging. Advanced audio codecs including LDAC, LDHC, AAC, and the full aptX family — covering aptX, aptX HD, aptX Adaptive, aptX Low Latency, aptX Lossless, and aptX Voice — are not supported. Bluetooth LE Audio and Auracast are also absent, and the earbuds do not offer fast pairing or NFC-based pairing.
The earbuds include a solid set of practical features, among them ambient sound mode, in-ear detection for automatic music pausing, a mute function, voice prompts, and a find device function for locating misplaced earbuds. They support multipoint connectivity for up to two devices simultaneously and can be used as a headset for calls. Controls are handled via a panel on the earbuds themselves rather than an in-line cable control. Fast charging is supported, and a travel bag is included in the box. Notification reading, a body temperature sensor, and a built-in camera remote are not available on this model.
The earbuds feature a three-microphone array with noise-canceling capability, allowing them to reduce unwanted background sound during calls and voice interactions.
