Restore your wireless freedom with our range of high-performance replacement batteries. If your headset is struggling to hold a charge or won’t power on at all, a simple battery refresh can return your headphones to their original runtime. We stock premium, high-capacity cells for Bose QuietComfort 35, Sony XM4, Beats Solo 3and many more ensuring you can keep your music playing without the cost of a new headset.

At Fix Headphones, we exclusively stock Cameron Sino batteries. While they may not be a household name, they are the industry leader in high-capacity cells for premium audio gear. We choose them because they are precision-engineered to match the exact voltage and safety standards of your Bose, Sony, or Beats hardware—offering a much safer and longer-lasting alternative to unbranded, generic batteries. Replacing a failing battery is one of the most effective ways to refurbish a premium headset, and we are proud to support users from the tech hubs of Manchester and Birmingham to the creative sectors of Bristol.

All our batteries are held in UK stock and are eligible for same-day dispatch if ordered before 12pm. Please note: Some battery replacements require technical skill or soldering. If you prefer a professional fix, please see our Mail-in Repair Services for expert installation.
