Sony True Wireless Earbuds with Charging Case, Silver, WF1000XM4/S

Hi Tokki17, Thank you for sharing your experience with the Sony WF-1000XM4 earbuds. We're very glad to hear that you consider them to be among the best sounding headphones you've owned. But we're sorry to learn that the battery life is not keeping up with your demands. Here are some troubleshooting steps that can help resolve this problem: 1. Update Firmware: Ensure your earbuds are running the latest software, as updates often include battery and power management improvements. Connect your earbuds to the Sony | Headphones Connect app and check for any available firmware updates. 2. Initialize the headset to restore factory settings. This will delete all pairing information and take the headset to factory settings.
