Bose QuietComfort Ultra Earbuds vs Sony WF-1000XM5 UK

The Bose QuietComfort Ultra Earbuds go head to head with the Sony WF-1000XM5 in the most asked premium earbud question in the UK right now, and the honest answer depends on whether you care more about silence or sound. Both earn five stars from the specialist press, and both are easy to find at Currys, John Lewis and Amazon UK. This comparison runs them through seven rounds so you can see which pair deserves your money.

One thing to get straight first. The Bose here is the QuietComfort Ultra Earbuds 2nd Gen, launched in 2025, so it is the newer product. The Sony WF-1000XM5 dates back to 2023 and was succeeded by the WF-1000XM6 in February 2026, which means you are weighing a fresh Bose design against a previous generation Sony flagship that has dropped a long way in price. That age gap shapes almost every round below.

Bose QuietComfort Ultra Earbuds vs Sony WF-1000XM5 specs at a glance

Before the rounds, here is how the two pairs line up on paper. Figures come from the Bose and Sony spec sheets, with measured numbers attributed in the rounds that follow.

Round 1: Noise cancelling

This is the round Bose is built to win, and it largely does. What Hi-Fi described the Bose effect as a cocoon that shuts out traffic, chatter and low rumble across the full frequency range, which matches the brand’s long reputation for shutting the world off. The Sony is not far behind, though, and the lab numbers tell a more nuanced story than the listening notes.

SoundGuys measured 87% average noise attenuation for the Sony and 85% for the Bose, with the Sony avoiding a small dip in the mid frequencies that the Bose shows. In practice both pairs erase most commuter noise, but the Bose wins on the feeling of sealed quiet while the Sony edges the raw measurement. For the daily reality of a London train or an open office, the Bose remains the one that disappears the outside world most convincingly. The Bose also benefits from CustomTune, which sends a tone into your ear at every insertion and tunes the cancelling to your individual ear canal, and that personal calibration is a big part of why its silence feels so complete. The Sony leans on its Integrated Processor V2 and twin feedback microphones, and while it is excellent, it does not quite match the Bose for that wall of quiet. If wide soundstage matters as much as silence, our look at the Sonos Arc Ultra covers the home side of the same trade off.

Winner: Bose. Its cocooning seal feels quieter even though the Sony posts a marginally higher attenuation figure.

Round 2: Sound quality

Here the older Sony pulls ahead. What Hi-Fi called the WF-1000XM5 more open, agile and articulate than the Bose, with extended treble and strong rhythmic precision. The 8.4mm Dynamic Driver X gives the Sony a tight, textured low end and the clarity to separate busy mixes. SoundGuys also gave the Sony higher objective sound scores in its testing.

The Bose is no slouch and many will prefer its smoother, weightier presentation with more powerful bass, which suits relaxed listening. But for outright resolution and rhythmic drive the Sony is the more capable pair, and its LDAC support gives Android owners a genuine hi-res path that the Bose cannot match without a Snapdragon Sound phone. If you are weighing over-ear options too, the Nothing Headphone 1 brings a different tuning at a lower price.

Winner: Sony. More detailed, more agile and better served by hi-res LDAC on Android.

Round 3: Calls and microphones

Call quality is close enough that the verdict shifts depending on conditions. What Hi-Fi found the Bose made voices weighty and prominent, while the Sony was the stronger performer at suppressing wind. SoundGuys leaned towards the Sony for outdoor and windy calls, which is where most people struggle.

The Bose 2nd Gen does add AI based background noise suppression for calls, a genuine upgrade over the first generation, so indoors it sounds clean and natural. Outdoors, though, the Sony still copes better with gusts. Most callers will be happy with either, which is why this one is a near draw rather than a rout.

Winner: Sony, narrowly. Better wind handling outdoors tips a very close round.

Round 4: Comfort and fit

Fit is personal, but the Bose has the edge for security. What Hi-Fi praised its slender stabilising wings for keeping the buds locked in during movement, and the second generation refines the shape with a rubberised guard that helps keep ear wax off the nozzle. For workouts and walks, the Bose feels the more dependable.

The Sony answers with sheer lightness. At 5.9g per bud it is among the smaller premium pairs, and it ships with four ear tip sizes against the Bose three, which helps awkward ears find a seal. Comfort over long sessions is excellent on both, so this comes down to whether you value a locked in feel or a barely there one. We give it to Bose for stability.

Winner: Bose. Stabilising wings hold firmer, even if the lighter Sony suits more ear shapes.

Round 5: Battery and charging

Sony takes the stamina round clearly. It rates the WF-1000XM5 at 8 hours per charge with noise cancelling on, and SoundGuys recorded an impressive 9 hours 32 minutes in its own test. The Bose is rated at around 6 hours, and SoundGuys measured 5 hours 34 minutes, with the case adding three full recharges.

Both cases reach roughly 24 hours in total and both support wireless charging, so the difference is really about how long you go between case visits. The Sony comfortably clears a long haul flight on one charge, while the Bose asks for a top up sooner. For frequent travellers that real world stamina lead is worth noting.

Winner: Sony. Longer single charge life in both the official rating and independent testing.

Round 6: App, EQ and extra features

Software is another Sony strength. The Sound Connect app offers a six band custom equaliser, adaptive sound control that switches modes by activity, Speak to Chat, and 360 Reality Audio with head tracking. SoundGuys flagged the wider EQ as a clear advantage over the more limited three band control in the Bose app.

The Bose counters with its Immersive Audio spatial mode and a new Cinema Mode in the 2nd Gen that widens stereo into a theatre style image, plus that AI call processing. It is a tidy, polished app, just less flexible for tweakers. If you want to compare how rivals approach features, our Soundcore Liberty 5 Pro guide shows what cheaper buds now offer, and the AirPods Pro 3 versus AirPods 4 piece covers the Apple side.

Winner: Sony. Deeper EQ and richer feature set, though Bose Immersive Audio is the more fun party trick.

Round 7: UK price and value

This is where the two year age gap becomes decisive. The Bose holds firm at £299, while the Sony has slid to roughly £179 to £199 and dips lower in sales. You are paying around £100 to £120 more for the Bose, and for that you mainly get the better seal and fit rather than better sound or stamina.

What Hi-Fi made the same call, handing value to the Sony despite its age. Unless ultimate noise blocking is your single priority, the price gap makes the Sony the stronger buy on paper. For broader options at this level, our best wireless earbuds in the UK list keeps track of where prices land.

Winner: Sony. Markedly cheaper for performance that matches or beats the Bose in most rounds.

Our verdict

Add up the rounds and the Sony WF-1000XM5 takes five to the Bose two, winning sound, calls, battery, features and price while losing noise cancelling and comfort. The newer Bose is the better engineered product in 2026 and the clear pick if blocking out the world is your one non negotiable, but for most UK buyers the older Sony delivers more for a good deal less money.

Choose the Bose if you commute through constant noise, want the most secure fit, or love the cocooning silence and spatial audio. Choose the Sony if you want the best sound, the longest battery and the strongest value, which describes most people most of the time. It is also worth remembering that the Sony’s price keeps falling while the Bose stays planted at £299, so the gap between them tends to widen rather than close as the months pass.

Our score: 9/10 (Bose QuietComfort Ultra Earbuds)

Our score: 9/10 (Sony WF-1000XM5)

Both earn a 9, but the Sony wins on value and the Bose on isolation, so the overall nod goes to the Sony WF-1000XM5 for the typical UK buyer.
