EU Battery Rules Force Redesigns of Headphones' Sealed Designs

21 October 2026

Article 11 of Regulation 2023/1542 requires portable batteries in products placed on the EU market to be removable and replaceable by the end user. Published in July 2023 and consolidated in EUR-Lex documents, the EU regulation gives some exemptions for safety, but the rules affect much of the headphone and portable audio market.

The regulation, which applies to products placed on the market incorporating portable batteries, covers categories as diverse as electric toys, medical devices, and smartwatches. Devices such as over-ear headphones marketed in the EU must have their batteries made accessible to end users.

The global headphone market reached 563 million units in 2023, according to analysis from Futuresource Consulting. True wireless devices accounted for 67% of shipments, while over-ear and on-ear headphones had a much smaller share.

Manufacturers of true wireless earbuds face significant challenges. These tiny devices use compact designs to fit all necessary components and a battery inside a lightweight shell. Multiple manufacturers use glue to secure the battery and solder joints that complicate disassembly.

True wireless stereo systems and headphone models also use adhesives and seals to maintain water resistance and ensure smooth surfaces. More significantly, the compact assemblies of true wireless earbuds require specialized manufacturing processes to integrate components.

In contrast, larger over-ear headphones have more internal space to accommodate user-accessible battery compartments. The required redesigns create operational challenges for global headphone brands across all product categories. These changes demand additional testing, may cause production delays, and disrupt optimized supply chains.

Furthermore, implementing solutions like detachable fasteners while maintaining water resistance and product integrity will increase manufacturing costs. An unexpected outcome of the regulation is that headphone repairability improvements are now driven primarily by EU compliance rather than consumer cost savings.

The European Commission designed these rules to promote better repairability, reuse, and durability. EU statistics show nearly six million tonnes of electronic-waste batteries were generated in 2020. This environmental impact motivates European lawmakers, even as manufacturers face redesign challenges.

Additional exemptions now apply to wearables like smartwatches, electric toys, and products covered by the ATEX Directive. Medical devices and certain household appliances including electric toothbrushes must only simulate removable batteries.

The regulatory landscape remains complex. While reserve-charging power banks receive exemptions, manufacturers must develop multiple strategies to comply. Some brands may redesign products for user-replaceable batteries, others may leverage repair networks, and some may create EU-specific product versions.
