Our Verdict
Bowers & Wilkins Pi7 S2 True Wireless
Devialet Gemini II True Wireless
The Bowers & Wilkins Pi7 S2 True Wireless and the Devialet Gemini II True Wireless are both premium earbuds. While both buds are well-built, the Bowers & Wilkins are a bit unique as their carrying case doubles as a wireless transmitter so that you can connect the buds to things like in-flight entertainment. They also support aptX Adaptive, which is a codec that dynamically adjusts its performance based on the content you're listening to, so you get either lower latency or better sound quality. However, the Devialet are more comfortable and stable in-ear. They also have a longer continuous battery life and a better overall noise isolation performance. Their companion app also offers a graphic EQ and presets so that you can adjust their sound.
