The XM6 is Sony's newer, pricier flagship, and the natural assumption is that it simply beats the XM4 across the board. Owner data doesn't fully back that up: the XM4 actually carries a higher ClearPick score (8.3 vs 8.0) built on a larger set of owner mentions, and it costs roughly $175 CAD less. This guide compares what owners of each headphone actually report — noise cancellation, comfort, and value — to sort out where the XM6's premium is earned and where it isn't, and where owners say the XM4 still holds up better than a spec-sheet comparison would suggest.

Noise cancellation and sound quality
This is where the XM6's upgrade is real. Its noise cancellation subscore (9.5) edges out the XM4's (9), and owners notice it in practice — one XM6 owner writes that the noise cancellation is next-level and the overall sound quality is fantastic. That said, the XM4 isn't a weak performer by any measure: its own ANC draws strong praise from owners, with one describing it as making airplane cabins silent, and another naming the XM4 their preferred pick for audio quality and ANC against other headphones they own. Sound quality tells a similar story — the XM6 scores 9 versus the XM4's 8.5, with owners crediting Sony's re-tuned drivers for a warmer, less harsh top end. XM4 owners, meanwhile, lean on the headphone's in-app EQ to shape the sound to their liking, with several mentioning specifically that the EQ unlocks a level of tuning that makes the older driver hardware feel current.
Comfort and fit
Comfort is the clearest regression in the XM6 lineup. Its comfort subscore (7.5) sits well below the XM4's (8.5), and the verified product data attributes this to thinner ear pads and an ANC microphone that protrudes into the cup, causing rubbing on larger ears during extended sessions. The XM4 isn't complaint-free here either — one owner says outright that the earcups are fairly shallow and don't fit larger ears well at all — but the balance of owner sentiment favours the XM4 on long sessions: one owner reports falling asleep on a 14-hour flight while wearing them, with 5–6 hours of continuous wear at least, and another names the XM4's battery life, noise cancelling, and sound quality together as the reasons it works best for office and travel use. The subscore gap and this pattern of long-session reports both point the same direction for anyone doing multi-hour sessions.
Price versus what you actually get
At roughly $373.60 CAD against the XM6's roughly $549 CAD, the XM4 costs about a third less while still posting the higher ClearPick score of the two. Its value subscore (9) reflects that gap directly, against the XM6's 8. One XM4 owner put it plainly: they were honestly shocked at how cheap these are, calling it a steal, and another calls the pair perfect for public transit, planes, and general public use at that price. The XM6's premium buys measurably stronger ANC and smoother sound — one XM6 owner, comparing it directly against the AirPods Max, says they returned the AirPods Max for the XM6 and found it lighter and easier to travel with — but on the data available, the premium doesn't buy a higher overall score or better comfort, which makes the case for upgrading conditional on how much those two specific gains matter to you.
Who It’s For
Owners consistently call it a steal at its current street price, and it posts the higher ClearPick score of the two while doing well on comfort for long sessions.

It has the strongest noise cancellation and smoothest sound in the lineup — worth the premium if you're not sensitive to the thinner ear pads.

Common complaints
Fit issues for larger ears
I wanted to like these so bad but they are fairly shallow and don't fit larger ears well at all.
r/buildapcsalesCrackling sound defect
I had to return mine. There was a crackling sound in one ear
r/buildapcsalesThe data doesn't support an automatic upgrade. The XM6 wins clearly on noise cancellation and sound tuning, and owners who prioritize those two things at almost any price will be satisfied with it. But it loses on comfort, costs about $175 CAD more, and currently carries a lower ClearPick score than the headphone it's meant to replace. Owners who already have a working XM4 and don't have a specific complaint about its ANC or sound have little owner-backed reason to spend more for the XM6. Buyers shopping new, without an XM4 already in hand, should weigh the XM6's stronger ANC against the XM4's better comfort and clearly stronger value story before paying the premium. If you're the kind of owner who runs the app EQ to dial in your sound anyway, that closes part of the sound-quality gap too, which tilts the decision toward the XM4 even further unless ANC in difficult environments is a daily need.
