Our Verdict
Bowers & Wilkins Pi7 S2 True Wireless
Denon PerL Pro True Wireless
The Denon PerL Pro True Wireless are better than the Bowers & Wilkins Pi7 S2 True Wireless. Both are premium earbuds designed for sound quality, but the Denon can stream higher-resolution audio with the aptX Lossless codec. They give you more options for customizing the sound profile, including a personalized EQ feature and a graphic EQ. Otherwise, they have a longer battery life and support multi-device pairing. However, the Bowers & Wilkins' case acts as a wireless transmitter, granting them extra versatility since they can receive audio from Xbox and PlayStation consoles. Their noise isolation is also much better.
