Select your device and check to see if the stuttering goes away. Click the speaker icon in the system tray and from the list of audio input/output devices, check if your device is listed twice, or if it’s listed but the system’s built-in speakers are selected. They might register as both a speaker and as a headset. Some speakers and headphones end up registering as two different devices. Generally, if the Bluetooth driver is the problem, you will experience lag with other Bluetooth devices too like keyboards.
If you’re using the generic drivers that Windows 10 installs, try installing dedicated Bluetooth drivers released by your system manufacturer. If you’ve just started using a new Bluetooth audio device, it’s a good idea to check if you have the correct Bluetooth drivers installed. If your Bluetooth audio problems have been there since day one, try every fix in this section, and the next one. If you’ve just gotten a new speaker or headset or you’ve been using one for a while and the audio is choppy here are a few fixes to try. In both cases, there doesn’t seem to be an obvious cause to the Bluetooth audio problems. Some will stutter from day one while others will do it at random. Bluetooth headphones and speakers at times start to stutter.
Bluetooth speakers aren’t meant to work over long distances but most have good range.
