The WH-CH510 headphones are designed for a mobile lifestyle. Thanks to the light and compact design that fits the ear, the headphones are pleasant to use. The long battery life of the WH-CH510 headphones, up to 35 hours, guarantees that there is enough power even for a long journey. If the headphones run out of power, a 10-minute quick charge gives you 90 minutes of playback time. The buttons on the headphones allow you to start and stop playback, browse songs and adjust the volume. Thanks to the fixed microphone, hands-free calls are easily managed without you even having to take the phone out of your pocket.
