Smart playback, high-quality listening, and clearer speaking without wires are the hallmarks of the PI7 Noise-Canceling True Wireless In-Ear Headphones from Bowers & Wilkins. Utilizing Bluetooth 5.0, your favorite music, podcasts, and other audio content is streamed and played back via two drivers per earbud for a richer soundstage. Each have a dynamic 9.2mm driver for mids and bass, and a balanced armature tweeter for the highs. Both also sport four dedicated amplifiers and 24-bit/48 kHz resolution. To further improve wireless quality, PI7 supports various aptX codecs (Standard, LL, HD & Adaptive). A 24-bit connection helps to ensure this vibrant audio is properly synced between the earbuds. Your listening experience is further improved by what you don't hear, as each earbud has a microphone and adaptive active noise cancellation technology. This monitors ambient noise levels, adjusting to filter out distracting noise. With the PI7, audio clarity goes both ways. You can use the PI7 earbuds to make hands-free calls and each earbud has two cVc mics to better pick up your voice when speaking. All of this and more can be done for up to 4 hours on a full charge, with an additional 16 hours of charging power available in the included wireless charging case.
