The Bose QuietComfort Ultra Earbuds Black are the first-generation QuietComfort Ultra Earbuds from 2023 in their plainest finish. Bose built them around two things: noise cancelling that CustomTune calibrates to your ears each time you put them in, and Bose Immersive Audio, which places the sound in front of you instead of inside your head. Bose rates them at up to 6 hours per charge with Immersive Audio off, or up to 4 hours with it on, and the case adds up to three more full charges.

Immersive Audio on the Bose QuietComfort Ultra Earbuds Black
Normal stereo in earbuds sounds as if it comes from the middle of your head. Immersive Audio processes the signal so it seems to come from a pair of speakers in front of you. Bose gives it three settings in the app: Still, where the sound stays in place and recentres on you once your head stops moving; Motion, where the sound follows your head as you walk; and Off, for standard earbud audio.
Still suits a desk or a plane seat. Motion is the one to use on a walk or a commute, because the stage does not swing each time you turn. Keep in mind that Immersive Audio costs battery: the Bose QuietComfort Ultra Earbuds Black drop from up to 6 hours to up to 4 hours per charge with it switched on.
Noise Cancelling Modes and CustomTune
The Bose QuietComfort Ultra Earbuds Black come with three preset modes. Quiet runs full noise cancelling with stereo sound. Aware lets outside sound in, with ActiveSense smoothing sudden loud noises such as a passing siren. Immersion combines full noise cancelling with Immersive Audio in Motion. In the Bose app you can also build your own modes with the cancelling level and Immersive Audio set how you like.
Each time you insert the Bose QuietComfort Ultra Earbuds Black, CustomTune plays a short tone, measures how it behaves in your ear canal and adjusts the sound and cancelling to match. A good seal matters for this, so try the other tip and band sizes before you judge the noise cancelling.
Nine Fit Combinations
The Bose QuietComfort Ultra Earbuds Black ship with eartips in S, M and L and stability bands in sizes 1, 2 and 3, which gives nine combinations; XS and XL tips are available through Bose support. The stability band rests in the ridge of the outer ear to hold the bud in place. With the Bose QuietComfort Ultra Earbuds Black, start with the medium tip and the size 2 band, then change one piece at a time until the fit feels secure and sound stays full when you move your jaw.
Battery and Charging
For the Bose QuietComfort Ultra Earbuds Black, Bose lists up to 6 hours of play with Immersive Audio off and up to 4 hours with it on; a fully charged case holds up to three extra full charges. A 20-minute charge in the closed case gives up to 2 hours of listening. Charging from empty takes up to 2 hours for the earbuds and up to 3 hours for the case, which charges over USB-C and has a 680 mAh battery according to Bose’s owner’s guide.
Bose does not list wireless charging for this first-generation case, so plan on a USB-C cable.
Connections, Codecs and Controls
The Bose QuietComfort Ultra Earbuds Black support multipoint, so they can stay connected to two devices at once — a phone and a laptop, for example — and they remember up to 6 devices in their pairing list. The Bluetooth range is up to 9 m (30 ft). They carry Snapdragon Sound certification with Qualcomm aptX Adaptive for phones that support it, and Google Fast Pair on Android 6.0 or newer.
Touch controls on the Bose QuietComfort Ultra Earbuds Black let you swipe to change volume, tap to play or pause and skip, and call up your voice assistant. The water rating is IPX4, which covers sweat and splashing water from any angle; Bose notes that this resistance is not permanent and can decrease with normal wear.
Why Black
Black is the safe pick among the first-generation colours. The Bose QuietComfort Ultra Earbuds Black look the same in a meeting, on a flight or at the gym, and the dark case hides the small scuffs that pockets and bags leave behind. Earwax and skin oils also show less on dark tips than on light ones. Wipe the case with a dry cloth now and then, and clean the tips and the nozzle mesh gently so the sound stays clear.
Who This Is Not For
Skip the Bose QuietComfort Ultra Earbuds Black if you want wireless charging — Bose does not list it for this case. If you plan to use Immersive Audio all the time, 4 hours per charge may feel short on long flights. IPX4 is fine for sweat but not for swimming or rinsing under a tap. And if you want the newest version, note that Bose has since released a 2nd Gen model, which is a separate product.
