What it is and who it suits

The Bose QuietComfort Earbuds 888507-0400 are true wireless in-ear headphones with adjustable noise cancellation and Bluetooth 5.3 connectivity. They deliver up to 8.5 hours of playtime per charge and come with a charging case that holds 2.5 additional charges for a total of 31.5 hours. The IPX4 rating makes them suitable for workouts and daily commuting in Twilight Blue.

Practical limits of Bluetooth 5.3

The earbuds maintain a stable connection within 30 feet of the source device. Multipoint pairing allows simultaneous connection to two devices, but audio quality and latency depend on the source codec support. The USB-C cable provided is 12 inches long, so charging from a wall outlet may require an additional adapter or longer cable not included in the box.

Installation experience

Three sizes of eartips and stability bands are included to help you find a secure, comfortable seal; achieving that seal is essential for both noise cancellation performance and bass response. The touch controls are customisable through the companion app, though new users may accidentally trigger commands while adjusting the fit. The compact case measures 1.38 by 2.76 by 1.90 inches and weighs 0.104 lb, so it slips easily into a pocket.
