Both flagship earbuds sit within about $30 of each other, so this is a tradeoff, not a splurge decision. We compared sound, noise cancelling, comfort and battery life to find out whether Sony's detail and longer battery beat Bose's comfort and real-world noise handling.
Our verdict
Get the Sony WF-1000XM6 if you listen critically and want the longest runway between charges; get the Bose QC Ultra Earbuds if fit and cancelling in layered noise matter more.
Best overall
~$280–330
Get it if you listen critically, want the longest battery runway of the two, and accept paying the higher of the two prices for it.
Most comfortable
~$250–300 Lowest price
Get it if comfort during long wear and cancelling noisy, layered spaces matter most, and you would rather buy the pair that goes on sale more predictably.
The price gapThe two ranges overlap
Each bar is an estimated price range, on one scale from ~$250 to ~$330.
Either way: Both sit near the top of the category, so neither is a mistake.
We compared measured noise-cancelling and sound-quality testing from What Hi-Fi, SoundGuys and Sound Advice against the price ranges we publish for both earbuds. We haven’t listened through either pair ourselves; the noise-cancelling and sound-quality findings come from What Hi-Fi’s, SoundGuys’ and Sound Advice’s measured testing, all linked where we cite them. Prices are always moving, so every button and link pulls the live listing.

The most complete-sounding earbud of the two, with more battery to spend
Get it if you listen critically, want the longest battery runway of the two, and accept paying the higher of the two prices for it.
Skip it if you wear earbuds for hours at a stretch, or you would rather take the softer fit and the pair that discounts more often.
Reviewers keep landing in the same place on sound: the Sony WF-1000XM6 is the more neutral, more detailed listen of the two. Sound Advice’s side-by-side found the Sony “more even-handed and natural-sounding,” with fuller mids and cleaner separation, while RecordingNow scored it ahead on sound quality outright, 8.6 to 7.9 out of 10.
SoundGuys’ measurements agree: the XM6 tracks close to their reference curve, where the Bose deviates further at both the bass and treble ends. A new driver and a genuine 10-band EQ, against Bose’s basic three bands, mean there’s real room to shape the tuning rather than accept it as given, and Sony’s LDAC codec adds a hi-res option that Android listeners on the Bose don’t get.
Noise cancelling is close enough at the top that What Hi-Fi and Sound Advice both call the overall gap small, but the two pull ahead in different situations. The XM6 adds an extra microphone per bud, eight total, and a new processor, and testing found it particularly strong against low, droning noise like a plane cabin or a train carriage. That mic array pulls double duty on calls too: AI beamforming isolates your voice from wind and background noise noticeably better than the outgoing XM5 managed.
Battery is the cleanest edge Sony holds: eight hours per charge with ANC on, against six for the Bose, for the same roughly 24-hour total once the case is counted. The tradeoff for all of this is comfort. The XM6’s hybrid tips and elongated shape create what Sound Advice describes as “subtle-but-constant pressure” during long sessions, a real step down from the Bose’s more forgiving fit. At ~$280–330, they launched above the outgoing XM5’s usual price and carry the higher of the two ranges compared here.

Softer, more secure, and the stronger pick in real-world chaos
Get it if comfort during long wear and cancelling noisy, layered spaces matter most, and you would rather buy the pair that goes on sale more predictably.
Skip it if you want the longest battery life or the most editable sound signature. The Sony holds both.
Comfort is where the Bose QC Ultra Earbuds (2nd Gen) put real distance between themselves and the Sony. Softer silicone tips, a shape Sound Advice calls more ergonomic, and included wingtips for extra security add up to earbuds several outlets describe as easy to forget you’re wearing after a few hours, a genuine advantage on long flights or full workdays. CustomTune, Bose’s auto-calibration routine, plays a short tone at every wear and adjusts both the noise cancelling and the sound to the shape of your ear canal, which is part of why the fit feels tailored rather than generic.
On noise cancelling, the Bose’s advantage shows up in specific, real-world settings rather than lab tone tests: SoundGuys and RecordingNow both found it holds up better than the Sony in busy, layered environments, cafes, streets, the clink and chatter a steady lab tone doesn’t reproduce.
SoundGuys measures the second-generation Bose at roughly 85 percent of outside noise removed, among the best figures it has recorded from any earbud. Sound-wise the Bose leans warmer and more consumer-friendly, with Immersive Audio spatial processing that widens the soundstage on supported content, though its three-band EQ leaves far less room to retune the signature than Sony’s ten bands allow.
The second generation fixed the previous model’s most annoying gap: the case now charges wirelessly, and Bose’s SpeechClarity processing makes outgoing calls clearer, an area where reviewers rate the Bose slightly ahead of the Sony. Battery remains the honest weak point at roughly six hours with ANC on, two behind the Sony, though the case makes up the difference for a matching 24-hour total. At ~$250–300, often toward the low end on sale, per Sound Advice’s pricing checks, the Bose is also the more frequently discounted of the two.
Strengths
Tradeoffs
Yes, for long-wear comfort and noise cancelling in busy, layered places. SoundGuys measured the second generation removing roughly 85 percent of outside noise, among the best figures it has recorded from any earbud, and the edge shows up in cafes, offices and streets rather than against a steady cabin drone. They list at $299 and routinely sell at $249–269, so ~$250–300 is the working price. They are not the pick for battery (about six hours with ANC on, two behind the Sony) or for an editable sound (a three-band EQ against Sony’s ten).

| Buy them if | you wear earbuds for hours at a stretch and firmer designs ache by hour two, or you take calls in noise; reviewers rate Bose’s SpeechClarity processing slightly ahead. |
| Skip them if | battery runway or a neutral, adjustable sound matters most. The Sony WF-1000XM6 wins both at ~$280–330. |
| Wait if | you are not in a hurry. The Bose discounts more predictably than the Sony; $249–269 is the price to plan around. |
7 common questions, answered.
It depends on the noise. Independent testing has the Sony slightly ahead against low, constant rumble like plane cabins and trains, while the Bose holds up better in busier, layered environments such as cafes and city streets. Neither is a clear overall winner; the difference shows up in which specific noise you’re trying to cancel.
The Bose, by most accounts. Its softer silicone tips, included wingtips and more ergonomic shape make it easier to forget you’re wearing them over a full flight or workday. The Sony’s stiffer hybrid tips and elongated shape create a subtle but real pressure that some listeners notice after a few hours.
Mostly, yes, both pair over standard Bluetooth and cover the basics on either platform. The gap is codec support: Sony’s LDAC hi-res codec only helps on Android phones that support it, and Bose’s aptX Adaptive has the same limitation. iPhone owners get neither codec’s hi-res benefit on either pair, since Apple doesn’t support LDAC or aptX.
The Sony, by two hours per charge: eight hours with ANC on against six for the Bose. Both land at roughly 24 hours total once their charging cases are factored in, so the practical gap is mostly about how often you need to drop them back in the case during the day.
They carry an IPX4 rating, the same as the Sony, which covers splashes and sweat but not submersion. That’s fine for a gym session or a light rain shower, but neither pair is built for swimming or a proper dunk.
The Bose discounts more often and more predictably, dropping to roughly $250 to $300 outside major sale events. The Sony WF-1000XM6 launched more recently and hasn’t settled into the same discount pattern yet, so patience pays off faster with the Bose if price is the deciding factor.
Rarely. List is $299, but they sell at $249–269 outside the major sale events, so full price is the wrong moment. At $250–270 they are the comfort-and-cancelling pick; at $299 the Sony’s longer battery and ten-band EQ, at ~$280–330, make it a much closer call.
