Medley Pebble – How to Improve Sound Quality

Use these steps if TV sound is distorted, too strong, or unclear.

Using Optical? Start with Step 1. Optical Volume Boost is available on Batch T24L2 and later.

Find Your Batch Number

Step 1 – Turn OFF Optical Volume Boost

If you are using Optical, press the transmitter’s OPT Volume Boost button once to turn Volume Boost OFF.

Sound clearer? Leave Volume Boost OFF. Use Volume Boost only when the TV sound is too quiet.

Step 2 – Check the TV Audio Format

If you are using Optical, open your TV’s Sound / Audio Settings and set the Digital Audio Format to:

PCM / Stereo

Avoid Dolby, DTS, or Bitstream. TV menus vary by model; this setting may also be called Digital Sound Out or Digital Audio Output.

Step 3 – Adjust the Earbud Volume

If sound is distorted or uncomfortable, lower the earbud volume a few levels. If voices are difficult to hear, increase the volume gradually until speech is comfortable.

Something Doesn’t Look Right?

Sound Is Bad on Only One Earbud

Put both earbuds back on the transmitter, wait a few seconds, then remove both together. If the same side still sounds different, follow the one-side sound guide.

Fix One-Side Sound

Sound Cuts In and Out

Keep the transmitter away from Wi-Fi routers, other Bluetooth transmitters, and large metal objects. Keep the earbuds within normal range of the transmitter and test again.
