Our Verdict
Bowers & Wilkins Pi7 True Wireless
Bowers & Wilkins Pi7 S2 True Wireless
The Bowers & Wilkins Pi7 S2 True Wireless are the next generation of the Bowers & Wilkins Pi7 True Wireless. Both buds have a premium design, bass-heavy sound profiles, and great noise isolation performances. Just like their predecessor, the S2's carrying case also acts as a wireless transmitter, so you can connect them to devices that otherwise don't support Bluetooth. That said, the S2 have an improved battery performance and now support aptX Adaptive, which allows you to stream high-quality audio or keep lower latency, depending on your content. However, the first gen support aptX-LL, which is designed primarily to lower latency for streaming video.
