Our Verdict
Sennheiser MOMENTUM True Wireless 3
Bowers & Wilkins Pi7 S2 True Wireless
The Sennheiser MOMENTUM True Wireless 3 have a slight edge over the Bowers & Wilkins Pi7 S2 True Wireless. While both buds are decently comfortable and have premium builds, the Sennheiser sound a bit more neutral but can be customized using their companion app's graphic EQ and presets. The buds have a significantly better battery performance, too. Conversely, the Bowers & Wilkins's case also doubles as a wireless transmitter, and they have a better noise isolation performance.
