Bowers & Wilkins Unveils PI7 S2 And PI5 S2 True Wireless ANC Earphones for 2023

In April 2022, Bowers & Wilkins announced the Pi7 and Pi5 noise-canceling earphones. This was the first time B&W had entered the TWS (True Wireless Stereo) earphone market.

Building on the foundation of those models, B&W has announced new upgraded versions, the Pi7 S2 and Pi5 S2 that are intended to replace their well-received predecessors.

What Both Models Feature

Although a lot remains the same, the Pi7 S2 and Pi5 S2 provide some subtle improvements over the Pi7 and Pi5. 

Improved Wireless Connectivity: The Pi7 S2 and Pi5 S2 incorporate upgraded wireless connectivity with a new antenna design that supports increased Bluetooth range (up to 25m).

Improved Battery Life: Both new models provide up to five hours of listening time before needing to be recharged. Also, the 15-minute quick charge function provides an additional two hours of listening time. In addition, the charging cases provide additional battery life (16 hours for Pi7 S2 and 19 hours for the Pi5 S2).

Music App: Pi7 S2 and Pi5 S2 are the latest earphones to be fully integrated with the Bowers & Wilkins Music App. The app provides a seamless user experience that includes set-up, configuration of noise cancellation modes, wear sensor adjustment, and a range of additional audio settings. The app also supports hi-res streaming direct from your mobile device via Qobuz, TIDAL, Deezer, and other select services. The Bowers & Wilkins Music App also offers additional user adjustments.

One Button Control: Both models include an easy-to-use one-button user interface.

The button allows listeners to perform multiple tasks. 

Voice Assistance: In addition to one button control, these earphones also provide Siri or Google Assistant voice support, depending on the connected device. 

Features on the Pi7 S2

The Pi7 S2 continues to offer Wireless Audio Retransmission, which was introduced in the original Pi7. This enabled users to connect to an external audio source – such as an in-flight entertainment system – and then retransmit audio wirelessly from that source to the earbuds, via the Smart Charging Case.

The Pi7 S2 also continues to provide Qualcomm® aptX™ Adaptive. This allows Hi-res audio to be transmitted from compatible streaming services and devices. 24-bit/48kHz wireless transmission between each earbud is provided.

Pi7 S2 features 9.2mm drive units, joined by a high-frequency “balanced armature” driver, with each of the four drive units (2 for each earbud) actively driven by its own amplifier. 

The Pi7 S2 also offers Adaptive Noise Cancellation to automatically monitor, analyze and adapt to its surroundings. That ANC system incorporates six microphones (3 on each earbud). In addition, to supporting ANC, the microphones optimize phone call sound quality.
