Our Verdict
Anker Soundcore Space Q45 Wireless
Bose QuietComfort Ultra Headphones Wireless
The Bose QuietComfort Ultra Headphones Wireless are better over-ears than the Anker Soundcore Space Q45 Wireless. The Bose are premium headphones with a more comfortable, well-built design and better overall noise isolation performance. They can access an Immersive Audio feature, which allows audio to follow your head movements, and they support aptX Adaptive, a codec that automatically adjusts to your content, ensuring either low latency or high audio quality. That said, the Anker are still worth considering if you're looking for significantly cheaper over-ears with excellent noise cancelling.
