You’ve narrowed it down to two headphones. The Sony WH-1000XM5 and the Bose QuietComfort Ultra sit at the top of every “best noise-cancelling headphones” list, they cost roughly the same, and they both promise to block out the world so you can enjoy your music in peace. The reviews are split. Your mates have opinions. And you just want someone to tell you which one to buy.

I’ve used both for over six months — the Sony on my daily commute into London and the Bose at home for evening listening. Here’s what I’ve found.
Quick Verdict
The Sony WH-1000XM5 wins for commuters and travellers who want the best noise cancelling, multipoint connectivity, and a lighter build. The Bose QC Ultra wins for music lovers who prioritise sound quality and want spatial audio that actually works. Both are excellent. Neither is a bad choice.
If you’re buying one pair for everything, the Sony is the safer bet. If audio quality matters more than anything else, the Bose edges ahead.
Noise Cancelling: The Main Event
This is what most people are buying these headphones for, so let’s start here.
Sony: The ANC King
Sony’s noise cancelling has been best-in-class since the XM3, and the XM5 maintains that lead. Eight microphones and two processors work together to analyse and cancel ambient noise. On a train, it reduces engine rumble to a faint hum. In a busy office, it’s like someone turned the volume down on the world. The auto-optimisation feature uses a sensor to detect whether you’re walking, sitting, or on transport and adjusts ANC accordingly.
The “Speak to Chat” feature pauses music and lets ambient sound through when you start talking — handy at coffee shops. After six months of commuting with these, I still find the ANC impressive every time I put them on.
Bose: Close but Different
Bose’s noise cancelling is very good — perhaps 90% as effective as Sony in most situations. Where it differs is in how it handles mid-range frequencies. Sony is better at blocking low rumbles (engines, air conditioning). Bose is slightly better at handling voices and mid-range clatter. In a busy café, they’re almost indistinguishable. On a plane or train, Sony pulls ahead.
Bose offers a transparency mode called “Aware” that’s more natural-sounding than Sony’s equivalent. When you need to hear an announcement or chat briefly, the Bose lets the outside in more convincingly.
Sound Quality: Who Sounds Better?
Here’s where opinions diverge, and it depends on what you listen to and how you listen.
Sony: Detailed and Bright
The XM5 has a V-shaped sound signature out of the box — boosted bass, slightly emphasised treble, with a slight scoop in the midrange. Vocals sit a touch behind the instruments rather than front and centre. For pop, hip-hop, electronic music, and anything with a strong beat, this sounds fantastic. For acoustic, classical, or vocal-heavy music, it can feel slightly thin.
Sony’s LDAC codec supports high-resolution audio up to 990kbps over Bluetooth (the What Hi-Fi LDAC explainer breaks down why this matters) — notably better than standard SBC or AAC. If you’re streaming from Tidal or Apple Music in lossless, the XM5 can actually take advantage of that.
Bose: Warm and Spacious
The QC Ultra sounds warmer, wider, and more natural than the Sony. Vocals are fuller, the soundstage feels more open, and there’s a richness to the midrange that makes acoustic instruments sound beautiful. Bass is punchy without being overwhelming. If you care about how music sounds — not just that it drowns out noise — the Bose is the more rewarding listen.
The standout feature is Bose Immersive Audio — their spatial audio technology. Unlike some spatial audio implementations that sound gimmicky, Bose’s version genuinely makes music feel like it’s in the room with you rather than inside your head. It works with any audio source, not just Dolby Atmos content.
The EQ Factor
Both headphones can be equalised through their respective apps. Sony’s EQ is more granular with a 5-band customisable equaliser plus preset profiles. Bose keeps it simpler with bass, mid, and treble sliders. If you’re willing to spend ten minutes tweaking the EQ, you can get both headphones sounding closer to each other — but out of the box, the Bose wins on sound quality for most genres.
Comfort and Fit for Long Listening
If you’re wearing headphones for hours at a time, comfort stops being a nice-to-have and becomes the deciding factor.
Sony: Lighter and Softer
At 250g, the XM5 is noticeably lighter than the Bose (roughly 18g difference). The ear cushions use soft synthetic leather that moulds to your head shape. The headband has minimal clamping force — comfortable for extended wear but they can shift if you’re moving around a lot. After a full day of wearing them in an office, there’s no discomfort. I’ve fallen asleep in them on more than one late train home. For a deeper understanding of what makes headphones comfortable, our complete headphone buyer’s guide covers fit, weight, and clamping force.
Bose: Heavier but Secure
The QC Ultra is about 268g — not heavy, but you notice the difference after two or three hours compared to the Sony. The ear cushions are plush and deeply padded, creating a good seal without excessive clamping. The headband distributes weight well. For gym use or active movement, the Bose stays put better thanks to slightly firmer clamping.
Both headphones fit glasses wearers well. Neither creates significant pressure points on the temples. If comfort is your top priority and you wear headphones all day, the Sony’s lighter weight wins.
Battery Life and Charging
Sony: The Marathon Runner
- With ANC on — up to 30 hours
- With ANC off — up to 40 hours
- Quick charge — 3 minutes of charging gives 3 hours of playback
- Full charge time — approximately 3.5 hours via USB-C
Bose: The Sprinter
- With ANC on — up to 24 hours
- With Immersive Audio — closer to 18 hours
- Quick charge — 15 minutes gives 2.5 hours
- Full charge time — approximately 2.5 hours via USB-C
Sony wins on total battery life by a significant margin. If you’re a frequent traveller or just hate charging things, the XM5 goes longer between charges. The quick charge on both is useful — Sony’s 3-minute top-up for a short commute is particularly handy.
Call Quality: Working from Home
With remote work now standard for millions of UK workers, call quality has become a genuine buying factor for headphones.
Sony: Improved but Still Behind
The XM5 improved call quality considerably over the XM4, with four beam-forming microphones and AI-based noise reduction. In a quiet home office, calls sound clear and professional. In a noisy environment — a café, a busy street — callers can still hear some background noise. It’s good enough for most work calls but not class-leading.
Bose: Better for Calls
Bose has traditionally been stronger on call quality, and the QC Ultra continues that tradition. Voice isolation is more effective in noisy environments, and callers consistently report a clearer, more natural voice. If you take a lot of work calls from varying locations, the Bose handles it better.

Build Quality and Design
Sony: Sleek but Fragile
The XM5 has a minimalist, modern design with a smooth headband and clean lines. It looks premium. The downside is the hinge design — unlike the XM4, the XM5 doesn’t fold flat. The carrying case is bigger as a result. The plastic construction feels solid but lighter than you’d expect at this price. Some users report the headband cracking after heavy daily use — something to be aware of.
Bose: Robust and Classic
The QC Ultra feels more solidly built, with a combination of metal and plastic in the headband. It folds flat for storage, and the included case is more compact. The design is more traditional — less fashion-forward than the Sony but arguably more timeless. Build quality inspires more confidence over the long term.
Commuting and Travel
For daily UK commuters — trains, the Tube, buses — the noise cancelling performance matters enormously.
Sony: The Commuter’s Choice
The combination of superior ANC, lighter weight, longer battery, and adaptive sound control makes the Sony the better commuter headphone. On a packed Northern Line train, the XM5 reduces the roar to a whisper. The auto-pause when you remove the headphones means you never miss a station announcement.
Bose: The Traveller’s Pick
For flights and longer journeys, the Bose’s fold-flat design and compact case give it a practical edge. The noise cancelling is very good on planes — not quite Sony-level on engine noise, but the more natural transparency mode makes interactions with cabin crew easier.
Music at Home: Critical Listening
When you’re sitting at home with a good album, priorities shift from noise cancelling to pure audio quality.
The Bose QC Ultra pulls ahead here. The wider soundstage and Immersive Audio make evening listening sessions really enjoyable. Put on a well-recorded album — Pink Floyd, Norah Jones, anything with good production — and the Bose makes you notice details you’ve missed before. The Sony sounds good at home too, but it’s designed for the noise and distraction of the outside world. The Bose is designed for the quiet of your living room. If you’re interested in how ANC technology actually works, we’ve covered the science in detail.
UK Price and Value
Current UK Prices
- Sony WH-1000XM5 — about £280-320 from Amazon UK, John Lewis, Currys, or Richer Sounds

The Value Equation
The Sony is £50-80 cheaper at typical UK prices. For most people, the XM5 offers better value — you get slightly better ANC, longer battery life, and a lighter build for less money. The Bose justifies its premium if sound quality is your priority and you’ll use Immersive Audio regularly.
Both headphones go on sale during Black Friday, Amazon Prime Day, and seasonal Currys promotions. The XM5 has been spotted as low as £230 during sales. Worth waiting if you’re not in a rush.
Frequently Asked Questions
Can the Sony XM5 and Bose QC Ultra connect to two devices at once? Yes, both support multipoint Bluetooth connectivity. You can pair them with your laptop and phone simultaneously and audio switches automatically between devices. Sony’s switching is slightly faster in practice.
Are the Sony XM5 good for the gym? They work for low-intensity gym sessions, but they’re not designed for exercise. There’s no IP rating for sweat or water resistance. For gym use, dedicated sport earbuds like the Sony WF-1000XM5 or Jabra Elite 8 Active are better choices.
Do the Bose QC Ultra have a wired option? Yes, both headphones include a 3.5mm cable for wired listening. This is useful on flights where Bluetooth might not be available, or when you want a zero-latency connection for watching videos.
Which headphones are better for phone calls? The Bose QC Ultra edges ahead for call quality, particularly in noisy environments. Both are fine for quiet home offices, but the Bose handles background noise more reliably during calls.
How long do these headphones last before needing replacement? With care, both should last 3-5 years. Battery degradation is the usual limiting factor — expect capacity to drop to about 80% after 2-3 years of daily use. Both have replaceable ear cushions, which extends comfort life.
