Samsung earbuds sound bad when paired to Galaxy watch

• The watch and headphones must be within Bluetooth range (about 30 feet). 
• The distance may vary depending on the environment and if there are obstacles, such as metals, walls, and electrical equipment between the devices. This could cause an echo while on a call.
• Make sure there aren't any other Bluetooth devices being connected at the same time.

Restart your watch and the headphones. If your watch is connected to a phone, you must restart the phone as well.

Once the devices are powered on again, check if they need to be charged. If the battery is critically low on either device, the audio quality may sound choppy or make weird noises.

From the watch's Home screen, press the Home key (Power key). Navigate to and tap Settings, tap Sounds and vibration, and then tap Volume. Tap Media, and then drag your finger across the volume bar to the right to increase the volume. 

If your watch only has a vibration option, you won't be able to adjust the volume from the watch. Instead, you can increase the volume within the app you're using to output audio to the headphones. 

Pairing a second set of headphones will help you determine if the problem is with the original headphones.

You can find instructions for pairing Bluetooth headphones to your watch here.

• If the second headphones are working properly, but the original headphones still have poor audio quality, contact the original headphone's manufacturer for further support.
• If you're experiencing the same issues with the second headphones, continue to step 6.

1. Navigate to Settings.
2. Swipe down to and tap General. 
3. Tap Reset. Tap Reset again to confirm.
4. If your watch is connected to your phone, you should get an option to back up your watch before resetting. Be sure to do this so you don't lose any data. Otherwise you will have to set up your watch again from the beginning.
