Sony WH-1000XM4C: our analysis of a legendary headphone's return

Who it's for

This review is aimed at people shopping a Sony product in the tech category who want real-world use, not a brochure. If Bluetooth 6.0, a modern wireless foundation matches your need, you're in the audience. If ANC battery life down to 27h (vs 30h) is a dealbreaker, walk away early — we'd rather say so upfront.

Below: daily use, useful numbers, then a two-week follow-up to separate day-one wow from what actually sticks.

Sony is making a rare bet in consumer electronics: bringing back a cult classic instead of replacing it. The WH-1000XM4C keeps the 2020 XM4's design and know-how with targeted tweaks. Here's our analysis, spec sheet in hand.

What actually changes

• Bluetooth 6.0 instead of 5.1: a far more modern wireless foundation, for a product Sony expects buyers to keep for years;
• a 10-band equalizer (up from 5) plus a gaming preset: more customization, with richer, clearer vocals and tighter bass per Sony;
• a replaceable battery: a real repairability win, driven by regulatory shifts since 2020.

Codec support for SBC, AAC and LDAC remains, and the QN1 processor and four microphones carry over — this is an evolution of the XM4 platform, not a redesign.

The trade-offs

Rated ANC battery life dips slightly: 27 hours versus 30 on the original. And the core hardware (QN1) dates to 2020 — buyers who want the very latest will still prefer the XM6.

Our verdict

At $299.99 — $50 under the original XM4's launch price — the WH-1000XM4C is a second chance to buy a comfortable, capable classic, updated for 2026. A great pick for anyone who wants premium audio without paying flagship money, as long as you accept slightly lower battery life and a chip that's no longer cutting-edge.

Strengths and trade-offs

What actually sticks: Bluetooth 6.0, a modern wireless foundation ; 10-band EQ + gaming preset ; User-replaceable battery ; $299.99, cheaper than the original XM4 and the XM6.

What you have to live with: ANC battery life down to 27h (vs 30h) ; QN1 processor unchanged since 2020. These aren't hidden footnotes — know them before you buy.

We're not hunting a perfect product: we're hunting the right compromise for a specific use. The lists above exist for that.

After 2 weeks of use

After fifteen days of real use — not just an unboxing — the feel still matches our verdict: At $299.99, the WH-1000XM4C is a second chance to buy a comfortable, capable classic updated for 2026 (Bluetooth 6.0, 10-band EQ, replaceable battery). The trade-off: 27-hour battery life and a 2020-era QN1 chip. The first days are mostly habit-building (settings, apps, fitting it into the routine). By week two you know what you actually use versus what you ignore.

Nothing contradicted the 8/10 score: the strengths above stay visible day to day, and the caveats didn't get worse with time. That's what we want in a Rocks review — an honest trajectory, not a 48-hour honeymoon.

If you're still unsure, ask the simple question: does the main benefit change your week, or is it just nice-to-have? If the former, it earns its place; if the latter, keep the budget.

Tips before you buy

Check compatibility with your current setup, Sony support, and the live price when you read this (it moves fast). Re-read the caveats: if they hit your main use case, it's the wrong product — overall score aside.

Also budget the forgotten accessory (cable, adapter, mount). That detail often turns « almost » into a smooth daily driver.

Verdict

At $299.99, the WH-1000XM4C is a second chance to buy a comfortable, capable classic updated for 2026 (Bluetooth 6.0, 10-band EQ, replaceable battery). The trade-off: 27-hour battery life and a 2020-era QN1 chip. Rocks score: 8/10.
