Bowers & Wilkins Pi6 review: great sounding earbuds with a classy build, but too few features to trounce rivals at the level

Bowers & Wilkins Pi6: Two-minute review

The Bowers & Wilkins Pi6 are a more 'budget' alternative to B&W’s big flagship pair for 2024, the Bowers & Wilkins Pi8. I put budget in quotation marks, because despite undercutting their siblings, the Pi6 are still a premium pair of buds in their own right when you consider that rivals come in at almost half the price – and some of those offer hearing tests, proprietary spatial audio solutions and personalised sound profiles.

Bowers & Wilkins is a name revered for top-tier audio, even if you’re getting the company's ‘budget’ option, and that’s emphatically the case with the Pi6. As soon as you start listening to them you’ll be serenaded with a detailed soundstage, a zealous sound and smart ANC that’ll strip away any distractions.

If you're all about audio and can't quite stretch to the premium B&W Pi8, these earbuds are still a viable option. But to start with the sound quality might be getting ahead of ourselves, because you certainly won’t start there – like me, you’ll probably begin by hitting your shins on the harsh edges that B&W has left about the place. These buds have a surprising number of cut corners for earbuds that cost this much.

Sadly, I found pairing with the Pi6 a torturous and ongoing process. I realise it's one person's experience, but nonetheless I reviewed over 30 pairs of wireless headphones and earbuds last year and I'm not slouch on this. It was difficult. For me, the initial set-up was a time-consuming struggle, which I went through on multiple devices to check whether it was just my phone being problematic. And sadly, the connection wasn’t 100% reliable even once the buds were paired, because Bower & Wilkins’ app would reliably fail to recognize the buds if I put them in my ears once the app was already open.

The app doesn’t offer any scope for Spatial Audio or otoacoustic hearing profile curation, which is fair enough, but there are one or two standard quality-of-life perks missing, such as ‘find my headphones’.

Fortunately, the Pi6 are nice and light to wear, making them comfortable to wear and reliable to place in your ear. Honestly, the great audio quality here could very well offset the omission of a few personalisation perks and my connectivity issues, and this review was initially meant to have a 4.5-star score. However, near the end of the testing I was having trouble getting the Pi6 to work before leaving home, once again, and so despite the fact I was meant to be testing the Pi6 I had to leave the house with another pair of buds. And if I choose not to use the Pi6, despite the great-sounding audio, then it makes it hard to wholeheartedly recommend them to someone else.

Bowers & Wilkins Pi6 review: Price and release date

• Released in September 2024, after Pi8
• Costs $199 / £219 / AU$449

You can buy the Bowers & Wilkins Pi6 for $199 / £219 / AU$449, so they’re mid-range buds that act as cheaper – though not ‘cheap’ – alternatives to the Pi8.

The Bowers & Wilkins Pi8 sell for $399 / £349 / AU$599, which is a big step up, and so people who don’t need the very best and want to save a few pennies will find it a tempting option, and they are absolutely worthy of consideration.

Both earbuds were announced at the same time in August 2024. The Pi8 were put on sale straight away while the Pi6 were released in September.

Bowers & Wilkins Pi6 review: Features

• App doesn't offer the plethora of features others can
• Persistent connectivity issues
• Quoted battery life is 8 hours, but didn't reach that

The Bowers & Wilkins Pi6 easily takes a top-three spot in my all-time ranking of the most troublesome earbuds to pair with.

Devices just refused to recognize the Pi6. That’s plural devices – I tried to connect to a smartphone, a laptop and an iPad during testing. On all occasions, the device stalwartly refused to ‘see’ the buds via Bluetooth, and I’d have to keep turning Bluetooth on and off before the planets aligned and the device found the Pi6. Mercury must have been in retrograde or something when I was trying to connect the buds to my iPad, because I simply never managed it – not once.

When I first paired the Pi6 to my smartphone, the right bud wouldn’t work, a process which was only fixed when I went through the entire process all over again and re-paired them to my mobile. And when it did work, the connection wasn’t always reliable, with the app not always recognizing the buds and the left earbud continuing to give up the ghost from time to time. Again, it's important to note this is my personal experience (and it's very different to the one Becky Scarrott had when testing the flagship Pi8) but still, it's valid: I'm a regular TechRadar audio tester and in this particular area, the B&W Pi6 were unusually troublesome.

Another weak link is the battery life. Bowers & Wilkins quotes the Pi6 as having an 8-hour battery life but from my testing, it fell an hour or so short each time. Seven hours is still just above average, but the case was the real issue. The charging case is meant to provide 24 hours of listening time but I found that the power on this would be much less than that.

I’d sometimes put the earbuds in after a few days of not using them, to find that the battery had fully drained, even if it was powered up before. I’d need to charge the buds back up again before using them.

There’s a smartphone app to provide some extra controls over the buds. However, this was chock-full of adverts for things like streaming service free trials and podcasts that B&W sponsors, and so the actual features feel somewhat hidden. You can turn on ANC or ANC pass-through, play with a simple equalizer (you can increase or decrease treble or bass), turn off or on the wearer detection and customize the touch controls.

Most of these are listed under the ‘Discover More’ section of the app’s home page, as though they’re optional extras instead of the main reason you’d download said app. That’s only if you have the buds paired though and remember, several times in my testing the app wouldn’t recognize that the buds were connected.

• Features score: 3.5/5

Bowers & Wilkins Pi6 review: Design

• Premium-feel, compact case
• Handy touch controls
• Four color options to pick from

The Bowers & Wilkins Pi6 come in a small pebble-like charging case. It measures 6.5 x 2.9 x 5.2 cm and weighs 46g so it’s nice and small. I had no issue popping it in a trouser pocket and forgetting about it for a day. The case doesn’t seem to have an IP rating.

The buds themselves are fairly light in weight, tipping the scales at 7g each. I found the fit to be comfortable and reliable, staying in my ears during a gym session amongst other activities, but several different ear tip sizes come in the box with the Pi6.

Each bud has a sensor on the top plate that you can use to control your music. Using these took a little bit of getting used-to (to figure out where to tap and how firm to be) but after a while it became a convenient way to handle the playback of my music. Using the app you can choose for the hold options to be to change the volume, or to handle ANC and summon your voice assistant.

You can pick up the buds in four colors. I used Cloud Gray but there’s also Glacier Blue (pale blue), Storm Gray (black) and Forest Green (olive).

I mentioned that the case doesn’t have an IP rating, but the buds do: they’re certified at IP54, which is a good dust-resistant and water-resistant rating – but I hope it goes without saying that you shouldn’t submerge them in water.

• Design score: 4.5/5

Bowers & Wilkins Pi6 review: Sound quality

• 12mm driver, but misses the Pi8's custom one
• Hearty bass and mid, treble falls a little short
• Support for a range of codecs

Bowers and Wilkins has managed to get a 12mm dynamic driver into each of the Pi6 buds, and they support SBC, AAC, aptX Adaptive and aptX Classic codecs.

The Pi6 sound great for their price, which is just as well given the lack of a hugely meaningful equalizer to let you fix any issues. I really enjoyed listening to music with them, when the buds worked.

The buds took a zealous approach to my music, with a meaty but not overwhelming bass and full-bodied mids, and a detailed soundstage helps you appreciate these elements. For certain kinds of music, the Pi6 were some of the best buds I’ve tested in some time.

If there’s an Achilles’ Heel, it’s the treble, which I found to lack an extra ounce of sparkle as well as prevalence in the mix. I found myself wishing female vocals and harmonising instruments were a little more prominent, and even maxing out the treble in the equalizer only went so far towards fixing the issue.

At least for the music I listen to, however, the treble was never a huge issue, but it’s something worth flagging to prospective buyers. A few features are missing in the Pi6 that show up in the Pi8, including aptX Lossless support, an advanced DAC and bespoke drivers, but those are pretty niche features that only certain audiophile-grade fans will really need.

• Sound quality: 4.5/5

Bowers & Wilkins Pi6 review: Value

• Don't offer fantastic value for money
• Hunt around for sales to save

The B&W Pi6 have great audio for the price and a nice light case design, but the value proposition is knocked by the limited feature set.

I’ve tested plenty of earbuds that cost a third of the price of the Pi6 and have more impressive feature sets, more detailed equalizers and apps that don’t attack you with advertising for music services, playlists or podcasts.

You’re paying a fairly high price for the audio tech here and even non-audiophiles will enjoy the sound quality. But you can definitely find earbuds that sound almost as good for around $120 / £120 / AU$300 if you shop around. You can even find the Pi6 for a lot less in sales, despite writing this review only a few months after their release, so shop around.

• Value: 3.5/5

Should I buy the Bowers & Wilkins Pi6?

How I tested the Bowers & Wilkins Pi6

• Tested for over three weeks
• Tested at home, in the office and at the gym

I tested the Bowers & Wilkins Pi6 (when they weren't testing me...) for roughly three weeks, due to the testing period falling over the Christmas break.

I've detailed lots of my testing process above; I used them alongside my phone, an iPad and a laptop, in a range of environments including my home, the office, public transport and the gym. I streamed music, played games and watched some TV too.

I've been testing gadgets for TechRadar for almost six years now, and in that time have tested a huge range of headphones and earbuds, so I'm used to troubleshooting and fixing faulty tech.
