Unpacking the Audio Fidelity: Sound Signature and Codec Support

The core appeal of the Bowers & Wilkins Pi7 S2 lies in their commitment to delivering exceptional audio fidelity. This isn’t just about loud bass.

It’s about nuance, clarity, and a faithful reproduction of the original recording.

B&W has a long-standing reputation in the audiophile world, and they’ve clearly aimed to translate that heritage into these true wireless earbuds.

Dual-Driver Technology for Rich Detail

One of the standout features contributing to their sound quality is the dual-driver design. Unlike many true wireless earbuds that rely on a single full-range driver, the Pi7 S2 employs a two-way system:

9.2mm dynamic driver: This handles the bass and mid-range frequencies, providing a solid foundation and warmth to the sound.
Balanced armature tweeter: Dedicated to the high frequencies, this tweeter ensures crisp, detailed highs without harshness.

This separation allows for a more articulate and expansive soundstage, preventing frequency ranges from interfering with each other.

The result is a sound that feels more open and less congested, even in complex podcastal passages.

You’ll notice better instrument separation and a clearer presentation of vocals.

AptX Adaptive: The High-Resolution Wireless Edge

For true wireless earbuds, the quality of the Bluetooth codec is paramount. The Pi7 S2 supports aptX Adaptive, a significant advantage for Android users and anyone with a compatible source device.

What it does: AptX Adaptive is a dynamic codec that adjusts its bitrate based on the content and surrounding RF environment. This means it can deliver up to 24-bit/48kHz high-resolution audio when conditions are optimal, approaching CD-quality and even beyond.
Benefits:
- Lower Latency: Important for video watching and gaming, minimizing audio lag.
- Better Reliability: Adapts to interference, ensuring a more stable connection.
- Higher Quality Audio: When bandwidth allows, it can stream significantly more data than standard SBC or AAC codecs.

While Apple users will still rely on AAC, which is excellent in its own right, the aptX Adaptive support truly unlocks the Pi7 S2’s potential for high-fidelity audio from Android devices, high-res audio players, or PCs with compatible Bluetooth transmitters.

Tonal Balance and Listening Experience

B&W’s sound signature typically leans towards a balanced, natural presentation with a slight warmth. The Pi7 S2 largely adheres to this.

Bass: Present and impactful, but not overwhelming. It’s articulate and well-controlled, avoiding muddiness. You can feel the thump without it bleeding into the mids.
Mid-range: Clear, natural, and expressive. Vocals come through with excellent presence and detail. Instruments like guitars and pianos sound lifelike.
Treble: Detailed and sparkling without being fatiguing. The balanced armature driver does an excellent job of reproducing cymbal crashes and high-hats with precision and air.

The overall impression is one of sophistication and accuracy. These aren’t earbuds designed to heavily color the sound. instead, they aim to present it as faithfully as possible. This makes them versatile across genres, from classical to rock to electronic. For critical listeners, this neutral-ish but engaging sound profile is highly desirable.

Noise Cancellation and Ambient Passthrough: Silence or Awareness?

In the increasingly crowded premium earbud space, effective noise cancellation ANC and transparent ambient passthrough are no longer just nice-to-haves. they’re essential.

The Pi7 S2 aims to deliver on both fronts, providing options for immersive listening or staying aware of your surroundings.

Adaptive Active Noise Cancellation

The Pi7 S2 features adaptive active noise cancellation ANC. This means the earbuds continuously monitor the environmental noise and adjust the level and type of noise cancellation in real-time.

How it works: Microphones on the exterior and interior of the earbuds pick up ambient sound. The earbuds then generate an inverse sound wave to cancel out the incoming noise.
Effectiveness:
- Low-frequency rumble: Like airplane engines, bus hum, or HVAC systems, are significantly attenuated. This is where most ANC excels, and the Pi7 S2 performs admirably.
- Mid-frequency sounds: Such as chatter or keyboard clicks, are reduced, but not entirely eliminated. This is typical for most earbuds, as these frequencies are harder to cancel without affecting audio quality.
- High-frequency sounds: Sharp, sudden noises like a car horn or a dropped object will still be audible, though their impact might be lessened.

Compared to the absolute best in class like Sony’s WF-1000XM5, the Pi7 S2’s ANC is very good, though perhaps not industry-leading. It provides a noticeable reduction in ambient noise, creating a quieter canvas for your audio. The adaptive nature means you don’t have to manually switch modes as your environment changes, which is a convenient touch.

Ambient Passthrough Mode

Sometimes, you need to hear what’s going on around you. This is where ambient passthrough or transparency mode comes in.

Functionality: External microphones pick up surrounding sounds and feed them into your ears along with your audio.
Quality: The Pi7 S2’s passthrough mode sounds quite natural, avoiding the overly digitized or tinny sound sometimes found in lesser implementations. Voices come through clearly, allowing for conversations without removing the earbuds.
Use cases:
- Public transport: Hearing announcements.
