Bowers & Wilkins Pi6 Review: Big Sound, Small Feature List

Bowers & Wilkins sells the Pi6 as its step-down true wireless earbuds, below the Pi8. This review brings together Bowers & Wilkins' own specifications and published reviews from What Hi-Fi?, TechRadar, Trusted Reviews, Hi-Fi Choice and Sound Advice, plus owner summaries from Best Buy and Crutchfield. JudgeAny runs no test lab, so every measurement and listening impression here belongs to one of those published sources, not to this site.

Sound: powerful, full-bodied, and best with energetic music

What Hi-Fi? describes the Pi6 as powerful and full-bodied, with good detail and bass that stays taut rather than turning bloated. Rock, hip-hop and heavy metal get the most from that character, while strings and vocals still come through with lifelike depth. TechRadar agrees on the broad shape — meaty bass and full-bodied mids — but finds the treble short of sparkle, so female vocals and harmonising instruments sit a little further back, and even the treble control in the app only partly fixes that. Trusted Reviews hears a more balanced and controlled performance than the Pi8, with an expansive soundstage, clear highs and strong, firm bass, and rates only the Technics EAH-AZ100 as better around this price. Hi-Fi Choice, listening across classical, electronic and dense guitar music, found the Pi6 able to pick out individual instruments without losing the low-end drive. Sound Advice reaches a similar place, calling the sound clear and balanced, with vocals and the top end given equal weight and bass that stays audible without crowding the melody.

Noise cancelling and calls: effective for steady noise, uneven for voices

What Hi-Fi? found that most background noise is softened if not entirely eliminated, while noting that the Bose QuietComfort Ultra Earbuds still set the standard for an all-encompassing cocoon of calm. There is no way to adjust ANC strength in the Bowers & Wilkins Music app, and only two modes are offered: standard ANC and a more transparent pass-through setting. Trusted Reviews used the Pi6 on planes, buses and shuttles and never felt let down, but judged the suppression a step below Bose, Technics and Sony, and found the transparency mode clear enough for conversation yet less detailed than Sony's and Bose's. Hi-Fi Choice makes a similar distinction: aircraft engine rumble is handled respectably, but voices and higher frequencies in a busy airport leak through quite noticeably. Sound Advice puts it more plainly, saying the ANC could not hold its own against a busy high street on a Saturday morning. On calls, the record splits. What Hi-Fi? heard voices that were clear, expressive and articulate, with some background noise even in quiet surroundings, and Sound Advice found both parties comprehensible without distortion. Trusted Reviews, by contrast, took a call at a noisy train station and was told its voice sounded distant, with surrounding noise dominating whenever it got loud.

Battery: the rated 8 hours is a moderate-volume figure, not a guarantee

Bowers & Wilkins rates the Pi6 at up to 8 hours per charge with ANC on, plus 16 hours from the case, for 24 hours in total, with a 2-hour full charge and a 15-minute charge worth 2 hours of playback. What Hi-Fi? found those numbers rang true in its testing, with the buds lasting to around their stated duration. TechRadar fell about an hour short each time, at roughly 7 hours, and reported a worse problem with the case: after a few days unused, it had sometimes drained completely, so the buds needed charging before use. Trusted Reviews measured a similar shortfall, with an hour of Spotify streaming at 50% volume using 14% of the battery, which points to just above 7 hours, and noted that its pair raced through the remaining charge once below a certain level, with the Android battery readout differing from the app's by as much as 4%. A Crutchfield owner reported the same pattern: a case charged the night before a trip held no charge the next day, while the buds themselves were down to 73%.

Fit, controls and the app: comfortable, but thin on customisation

At 7 g per earbud, with four ear tip sizes from extra small to large, the Pi6 is comfortable for long sessions in every published review, and TechRadar's reviewer kept them in through a gym session. The fit has limits: Trusted Reviews found the buds a little loose at times and needing a twist and push to tighten, Hi-Fi Choice doubted they would stay secure through energetic jogging, and there is no ear tip test in the app to confirm a seal. Controls are tap-based and, once learned, handy, per TechRadar, but the app only allows two paired choices for the hold gesture — ANC and voice assistant, or volume — with no double or triple tap, per What Hi-Fi?. The app itself is the thinnest part of the package: a 2-band EQ for bass and treble only, no spatial audio, no find-my-headphones feature, and, per TechRadar, streaming-service adverts that bury the real settings under a Discover More section. Trusted Reviews adds that wear detection works as it should, and that the Bluetooth connection itself held up, even if the soundstage sometimes compacted under interference.

Pi6, not Pi8: what the step down actually removes

The Pi6 shares the Pi8's shape, dimensions and weight, per What Hi-Fi?, but the internals and the case are different, and buyers should not expect flagship features at this level. The Pi6 uses 12 mm bio-cellulose drivers, while the Pi8 uses carbon cone drivers, per Bowers & Wilkins and Hi-Fi Choice. The Pi6 supports aptX Adaptive, aptX Classic, AAC and SBC, but not aptX Lossless, which is a Pi8 feature. The Pi6 case is a plain charging case: it does not retransmit audio from wired sources, as the Pi8 case does, and it does not support Qi wireless charging, per Hi-Fi Choice and What Hi-Fi?. The EQ is 2-band rather than the Pi8's 5-band, per Notebookcheck. The step down gains battery life: the Pi6 is rated at 8 hours per charge against the Pi8's 6.5 hours, per Hi-Fi Choice, and Bowers & Wilkins itself acknowledges that the Pi6's noise cancelling is not quite as effective as the Pi8's.

The conflicting evidence, and why the verdict still holds

The published record pulls in different directions on four points, and each one is worth naming. On battery, What Hi-Fi? matched the rated 8 hours, while TechRadar and Trusted Reviews both landed near 7 hours and reported case drain when the buds sat unused. On calls, What Hi-Fi? and Sound Advice found voices clear and comprehensible, while Trusted Reviews found its voice distant and swamped by station noise. On noise cancelling, Trusted Reviews was satisfied on planes and buses, while Sound Advice would not rely on the Pi6 on a long-haul flight and Hi-Fi Choice found airport voices leaking through. On connectivity, Trusted Reviews reported a strong Bluetooth connection with no real faltering, while TechRadar struggled to pair the buds across a phone, a laptop and an iPad, never managing the iPad at all, and What Hi-Fi? saw intermittent dropouts, once or twice over several weeks, in which sound moved from one ear to the other. None of these conflicts overturns the core claim, because the verdict does not rest on class-leading ANC, call quality, or hitting 8 hours exactly. Every outlet that criticised battery, calls, ANC or pairing still praised the sound and the comfort, and the step-down price against the Pi8 is the point of the product. The verdict survives as a conditional recommendation, resting on sound and comfort rather than the feature list.

Who should buy it

Buy the Pi6 if music comes first, especially rock, hip-hop and other energetic genres, and you want a comfortable, premium-feeling pair of earbuds with solid ANC for steady background noise and a longer rated battery life than the Pi8. It suits listeners who are happy with a simple app and a simple set of controls. Skip it if your day is mostly calls in noisy places, if you need adjustable ANC, spatial audio, wireless charging or a retransmitting case, or if trouble-free pairing matters more than sound, since TechRadar's pairing experience was unusually difficult and Best Buy's owner summary flags connectivity stability alongside the premium price. Bowers & Wilkins now files the Pi6 specification page under its archive section, so check availability as well as the current price on Amazon before buying. Best Buy's owner summary for the Cloud Grey version reported 44 reviews with 86% recommending the earbuds, praising sound, comfort, battery and fit — a picture that matches the published reviews more closely than any single complaint does.
