Bose's new flagship TWS earbuds are now officially Ultra as well as QuietComfort-series flagships. They are rated for the same high-end specs as their Headphone counterparts - first-gen Immersive Audio included - just in a TWS IPX4-rated package. Then again, potential customers may find their battery life does not match up to their sky-high pricing.

The "iconic" Bose QuietComfort name is officially back in TWS earbud form. They are also Ultra for the first time, due to signature "realistic" sound augmented with an upgrade to Immersive Audio. This OEM's long-awaited take on spatial audio has "Motion" and "Still" modes, rated to keep the impression of a "wider, more spacious soundstage" constant should the user move around or not respectively.

The QuietComfort Ultra Earbuds also support specs conferred by the same internals as the new flagship Headphones, not to mention the same CustomTune sound calibration. They also boast mics and internal filters touted to adapt "dynamically" to wind noise for ideal vocal audibility during phonecalls.

The latest Bose flagship earbuds look a lot like their predecessors, although there is a new "metallic treatment" to their wide touch-responsive stems intended to help them match the new QuietComfort Ultra headphones. They are now available to pre-order direct from the OEM in the same Black or White Smoke colorways for US$299.

Nevertheless, Bose only mentions a total of 6 hours of use per charge for that price in relation to its new Earbuds - which drops to 4 with the fancy new spatial audio setting on.

Then again, the Ultra Earbuds do charge wirelessly now - albeit only when inserted into their "optional new wireless charging case cover", priced at US$49 on It is, however, also compatible with the previous generation, which might encourage QC II owners to keep those buds going for longer.
