Sony WF-1000XM6 vs. Bose QC Ultra Earbuds: Sound or Silence?

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 $329.99 list on Amazon, they launched thirty dollars above the outgoing XM5 and carry the higher of the two prices compared here.

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 $299 list and routinely $249 to $269 on sale, per Sound Advice’s pricing checks, the Bose is also the more frequently discounted of the two.
