Our Verdict
Bose QuietComfort Earbuds II Truly Wireless
Bose QuietComfort Ultra Earbuds Truly Wireless
The Bose QuietComfort Ultra Earbuds are the next generation of the Bose QuietComfort Earbuds II Truly Wireless. That said, the differences between them are fairly minimal. Both buds share a similar sound profile that you can further tweak via the Bose Music app, and they're both equipped with Bose's excellent ANC technology. The QuietComfort Ultra are equipped with Bose's new Immersive Audio feature, though, which can help offset the poor passive soundstage performance that's commonplace with in-ear designs.
