Sony XM4 headphones reboot falls flat: why reboots are so hard

Show summary Hide summary

Sony has revived a fan favorite by reintroducing a refreshed take on the WH-1000XM4 lineup. The new WH-1000XM4C (second generation) aims to marry familiar comfort with updated audio tuning — all while sitting below Sony’s current flagship price. I spent two weeks with the headphones to test sound, noise cancellation, battery life, and whether this reboot is worth your attention.

What the Sony WH-1000XM4C brings to the table

The XM4C keeps the shape and feel many users loved, but adjusts the sonic profile and app features to meet today’s expectations. This is not Sony’s top-tier model. Instead, it is a reworked version of the XM4 designed to be a more affordable, modern option.

Technical highlights and essential specs

Below are the most important specs to know before deciding.

  • Processor: QN1 used for active noise cancellation (ANC).
  • Battery life: 27 hours per charge under typical use.
  • Equalizer: 10-band adjustable EQ in the companion app.
  • Microphones: Four mics for calls and ANC.
  • Multipoint pairing: Connects to two devices at once.
  • Colors available: Black, lavender, platinum silver.

Sound quality and software: what changed

Sound tuning is where the XM4C shows its biggest updates. The audio leans closer to Sony’s more recent flagships, offering clearer highs and fuller mids than the original XM4 out of the box.

EQ and app improvements

  • The app now features a 10-band equalizer, up from five bands.
  • New presets include a dedicated gaming option.
  • Fine adjustments let listeners tailor the profile for music, podcasts, or games.

Across tests — from live recordings to jazz and gaming audio — the XM4C performed as a balanced, everyday headphone. It rarely astonished, but it reliably delivered detail and a pleasing tonal balance for its price range.

Design, comfort, and portability

Physically, Sony stuck with the XM4 silhouette. The result is a lightweight, compact pair of over-ears that fold easily for travel. Padding is soft and supports long listening sessions without fatigue.

  • Low-profile earcups make the headphones less obtrusive.
  • Construction favors comfort over flashy materials.
  • They fit easily into a day bag or carry-on.

Noise cancellation and battery trade-offs

ANC remains powered by the same QN1 processor and a set of four microphones. Performance is still solid and competitive with many rivals.

However, Sony did not advance the ANC hardware significantly. That choice keeps costs down, but it feels like a missed chance to push the tech forward.

Battery life dipped slightly versus the first XM4. The new model provides 27 hours, compared to about 30 hours from the original. It’s a modest decline, but noticeable on paper.

Price positioning and how it compares to Sony’s current flagships

The XM4C launches at $299.99, meaning it undercuts the WH-1000XM6, which currently lists for around $459.99. That price gap is the main selling point.

  • The original XM4 can still be found discounted, sometimes below $230.
  • XM4C sits between the older model’s value deals and the latest flagship’s higher feature set.
  • Compared to mid-range competitors, the XM4C often costs less than similar offerings from other brands.

Who the WH-1000XM4C is made for

If you want a comfortable, travel-ready pair with improved tuning and a fuller app-based EQ, the XM4C fills that role well. The headphones are tailored for users who value balanced sound and solid ANC without paying flagship prices.

For bargain hunters, older XM4 units on sale remain tempting. For buyers seeking the absolute newest ANC tech, Sony’s WH-1000XM6 still holds an edge.

Real-world impressions and deal potential

During everyday use, the XM4C proved to be a dependable workhorse. Calls were clear, music sounded engaging, and the multipoint option made switching between laptop and phone seamless.

With Black Friday approaching, pricing could improve. That makes the XM4C an appealing candidate for shoppers looking to maximize value while getting a near-flagship listening experience.
