On headphones
-
Be sure to match the right and left side of the headphones with your ears.
-
When the volume is too high, the sound leaks outside the headphones. Be careful not to raise the volume so high that it bothers people around you. There is a tendency to raise the volume when using in noisy places. However, for reasons of safety, it is advised to keep the volume at a level whereby you can still hear sounds around you.
-
The earpads may deteriorate due to long term storage or use.
On the built-in rechargeable battery of the headphones
-
Charge the battery in an ambient temperature of between 5 °C and 35 °C (between 41 °F and 95 °F). If you charge it outside the recommended temperature range, the charge indicator flashes and the battery may not be charged.
-
If you store the headphones for more than a year, charge the battery once a year to prevent over-discharge.
-
If the length of time you can use the headphones became extremely short, the rechargeable battery should be replaced with a new one. Please contact your nearest Sony dealer for a battery replacement.
