Low sound quality
- If the size of the earbud tips does not match the size of your ear canals or the headset is not properly worn on your ears, tap operations or the speech detection of Speak-to-Chat may not be successful, or you may not obtain proper sound qualities, noise canceling effects, or call performances.
If any of this is the case, try the following.- Change the earbud tips to ones that fit more snugly in your ears. When changing the earbud tips, try the earbud tip sizes in order from the larger ones to the smaller ones. The size of the left and right earbud tips may be different.
The “Sony | Headphones Connect” app will help you to determine which earbud tips are most suitable for you to achieve the optimal noise cancellation effect. - Check if the headset is properly worn on your ears. Wear the headset so that the earbud tip is comfortably situated as deep in the ear canal as possible.
- Change the earbud tips to ones that fit more snugly in your ears. When changing the earbud tips, try the earbud tip sizes in order from the larger ones to the smaller ones. The size of the left and right earbud tips may be different.
- Turn down the volume of the connected device if it is too loud.
- Switch the Bluetooth connection to A2DP with the connected device when the headset and the transmitting Bluetooth device are connected via an HFP or HSP Bluetooth connection.
- If the headset connects to the previously connected Bluetooth device, the headset may only establish the HFP/HSP Bluetooth connection when it is turned on. Use the connected device to connect via an A2DP Bluetooth connection.
- When listening to music from a computer on the headset, the sound quality may be poor (e.g., difficult to hear the singer’s voice, etc.) for the first few seconds after a connection is established. This is due to the computer specifications (priority on stable connection at the start of transmission and then switches to priority on sound quality several seconds later) and is not a headset malfunction.
If the sound quality does not improve after a few seconds, use the computer to establish an A2DP connection. As for the operations on your computer, refer to the operating instructions supplied with the computer.
