NeverSleep Speaker

Prevents Bluetooth speakers and headphones from auto-powering off by playing inaudible keep-awake signals.

NeverSleep Speaker is a lightweight, privacy-focused Chrome extension designed to prevent Bluetooth speakers, headphones, and soundbars from automatically turning off when nothing is playing. Many modern audio devices have aggressive power-saving systems that shut them down after just a few minutes of silence/inactivity. This forces you to constantly turn your speaker back on, reconnect it, or listen to loud, annoying voice alerts like "Power Off" or "Bluetooth Disconnected." NeverSleep Speaker solves this problem by playing a continuous, completely silent sound in the background using Chrome's built-in audio system. Because this sound is played at a volume or frequency that human ears cannot hear, it keeps your speaker active and connected without making any noise. The extension features a beautiful dark-mode control panel where you can choose between four different silent signal modes, set a sleep timer (from 15 minutes to 8 hours) to save battery, and watch a live countdown timer. It runs entirely on your computer, tracks no data, and is the perfect tool for keeping your Bluetooth speaker awake and ready to play sound instantly. Best of all, keeping this active does not consume any noticeable CPU or battery power, ensuring your computer stays fast and efficient.
