Our Verdict
Anker Soundcore Space Q45 Wireless
Sennheiser ACCENTUM Wireless
The Anker Soundcore Space Q45 Wireless have the edge over the Sennheiser ACCENTUM Wireless. The Anker are more comfortable, have a significantly better noise isolation performance, and support LDAC, which is Sony's proprietary codec for streaming audio in higher resolutions. However, the Sennheiser have a more balanced mid-range out of the box, and their continuous battery life is longer.
