Sony has been making the best-selling ANC headphones on the market for four generations. The WH-1000XM6 makes one change that's immediately obvious when the box arrives: the carry case is genuinely smaller. Not slightly smaller — it went from a medium-size oval puck that barely fit in a backpack's laptop compartment to something you'd comfortably toss in a daypack side pocket without rearranging everything else.

I ordered the XM6 in Platinum Silver from Sony's website ($349). The outer shipping box is small enough that I initially thought Sony had sent the wrong order. Inside was Sony's product packaging: a matte grey outer sleeve that slides off to reveal a sturdy grey box with a simple Sony logo stamp.

Everything in the Box

  • WH-1000XM6 headphones — folded into the carry case, ear cups stowed flat
  • New compact carry case — hard-shell clamshell design, roughly 22cm × 17cm × 7cm. Previous XM5 case was 23cm × 19cm × 9cm. Doesn't sound dramatic, but the reduction in depth is the part that makes it fit in more bags
  • USB-C charging cable (1.5m) — no braiding, which is a minor complaint at $349
  • 3.5mm audio cable (1.2m) — for wired listening on in-flight entertainment
  • Airplane adapter — dual 3.5mm plug for older seatback systems
  • USB-C to USB-A adapter — a nice inclusion for people whose laptop only has USB-C ports and whose airplane USB charger is USB-A
  • Quick start guide

No power adapter, which has been consistent across Sony's headphone line for years. USB-C charging means any USB-C adapter works; the included cable handles data and charging.

The New Case in Detail

The XM5's carry case was one of the chief complaints in user reviews — too big, didn't fit comfortably in most bags without awkward orientation. Sony listened. The XM6 case has a revised fold mechanism that tucks the headphones tighter: the ear cups now fold at an angle rather than rotating flat, which is a slightly different fold than the XM5 but ends up taking less overall volume.

The case zipper has a smoother action than the XM5's. The exterior fabric is slightly softer — less of the rubbery feel that picked up lint from bags. Inside, there's a small mesh pocket for the cables and adapters. The headphones sit snugly; there's minimal movement inside the case when you shake it.

The one thing the new case loses: the XM5's case had a small loop for attaching it to bag straps. The XM6 case doesn't. If you commute by train and like clipping things to your bag exterior, you'll miss this.

Build Quality First Impressions

The XM6 headphones themselves look very similar to the XM5. The headband has been slightly revised — the underside cushioning is 2mm thicker, which you can feel immediately when putting them on. The ear cups are the same 40mm driver configuration but the earpads have been updated to a synthetic leather that Sony claims is more breathable. After an hour of wearing, there was noticeably less warmth buildup than I typically get with the XM5.

The headband adjusters have a tighter click mechanism than the XM5. This sounds trivial but it matters: the XM5's adjusters would occasionally slip under sustained movement. The XM6's don't, at least in the first few days of use.

Touch controls are on the right ear cup, same as XM5 and XM4. The XM6 adds a swipe gesture for adjusting noise cancellation levels directly on the cup, which was previously only accessible through the Sony Headphones Connect app. First-generation owners: you can now cycle through NC modes without taking out your phone.

Noise Cancellation First Impressions

Sony claims the XM6 uses an updated QN3 processor with "next-generation beamforming microphones." I tested noise cancellation on a commuter train and in a busy coffee shop for this unboxing write-up — more rigorous testing will come in the full review. Initial impression: the ANC is at least as good as the XM5's, which was already class-leading, and the transition between modes is faster. The wind noise reduction improvement is the one I've found most noticeable so far — windy outdoor use with the XM5 would sometimes trip the ANC in an audible way; the XM6 has been more stable in the same conditions.

What Didn't Change

The touch control layout is identical to the XM5. Sound quality from the first listen is Sony's house sound: full-bodied bass, slightly smoothed treble, good instrument separation. If you know what the XM5 or XM4 sounds like, you'll feel immediately at home. Sony hasn't dramatically retuned the sound signature, which existing fans will appreciate and people who found the XM5 bass-heavy will not see resolved.

Battery life is quoted at 30 hours with ANC on, same as the XM5. Charging to full takes about 3.5 hours; 10 minutes of charging gives roughly 5 hours of playback. Also the same as XM5. These aren't complaints — 30 hours is excellent — but if you were hoping for a leap to 40+ hours, this isn't the generation for it.

The Box Verdict

The XM6 box includes everything you need plus a few thoughtful extras (airplane adapter, USB-C to USB-A adapter). The new carry case is the most immediately useful improvement Sony has made to the package in two generations. Build quality feels solid, the fit improvements are real, and the ANC first impression is strong. Full sound and ANC evaluation in the forthcoming review.
