Our Verdict

Bose QuietComfort Earbuds Truly Wireless

Bose QuietComfort Ultra Earbuds Truly Wireless

The Bose QuietComfort Ultra Earbuds Truly Wireless are a newer version of the Bose QuietComfort Earbuds Truly Wireless, and are quite similar. Both have an excellent noise isolation performance and a somewhat bass-heavy sound profile out of the box. The Ultra are equipped with Immersive Audio, which can help improve their soundstage performance compared to other in-ears.
