Using hybrid noise-canceling technology and supporting the aptX codec, the spring lilac Pi5 S2 Noise-Canceling True Wireless In-Ear Headphones from Bowers & Wilkins can deliver high-quality music reproduction without distraction. Hybrid ANC technology uses two microphones per earbud to listen and filter out exterior ambient noise, and correct for errors by listening to what you're hearing in your ear. This technology is also useful on hands-free calls when paired with a smartphone, letting you better hear the conversation in crowded spaces. The Pi5 S2 earbuds deliver up to 5 hours (ANC off) of power, with another 19 hours available inside the included wireless charging case.
