Our Verdict
Bose QuietComfort Earbuds II Truly Wireless
Bowers & Wilkins Pi7 S2 True Wireless
The Bose QuietComfort Earbuds II Truly Wireless are slightly better earbuds than the Bowers & Wilkins Pi7 S2 True Wireless. The Bose are more comfortable, and are more customizable, thanks to their companion app's graphic EQ and presets. They're also able to block out a bit more background noise and their battery performance is significantly better too. However, the Bowers & Wilkins are better-built, support aptX Adaptive codec for streaming high-quality audio and lowering latency, and their carrying case can be used as a wireless transmitter.
