Sony has quietly announced a revised version of its popular WH-1000XM4 headphones, the WH-1000XM4C, featuring a removable battery. This change is a direct response to upcoming European Union regulations that require consumer electronics to have easily replaceable batteries by 2027.
The original WH-1000XM4, released in 2020, earned praise for its comfortable design, excellent sound quality, and top-tier noise cancellation. Despite newer models, many users still consider it a benchmark. The new "C" variant aims to extend the life of this classic while complying with the new rules.

Why the EU Battery Regulation Matters
In 2023, the EU passed a battery regulation mandating that all consumer products with integrated batteries allow for easy removal and replacement by February 2027. This applies to everything from smartphones to headphones, forcing manufacturers to rethink design.
The goal is to reduce electronic waste and promote repairability. Companies can comply by using less adhesive, designing for easier disassembly, or making batteries user-replaceable. Sony's approach with the WH-1000XM4C falls into the latter category.
What's New with the WH-1000XM4C?
Aside from the removable battery, the WH-1000XM4C appears to be identical to the original. It retains the same 30-hour battery life, industry-leading noise cancellation, and comfortable fit. The key difference is that users can now swap the battery themselves, extending the product's lifespan.
This move is significant because it shows how regulations can drive design changes even for established products. Instead of discontinuing the XM4, Sony chose to adapt it, likely to maintain a lower-priced option in its lineup.
Impact on Consumers and the Market
For consumers, a removable battery means you can keep using your headphones for years, even after the battery degrades. This is a win for sustainability and for your wallet. It also puts pressure on competitors to follow suit. The longer history behind the story is traced in Sony WH-1000XM4C: Removable Battery for EU Compliance.
However, the WH-1000XM4C is currently only announced for the European market. It's unclear if it will be available globally. Sony may be testing the waters or limiting the variant to regions where required. The background to this story is set out in Technology: latest articles.
