  • Charging your headphones:

Even though your headphones will come with some battery charge, it’s advisable to fully charge them before first use. Connect them to a suitable USB power source using the USB lead provided and leave charging for around 2.5 hours or until the red charging LED goes out. After fully charging you should get around 10 hours of playtime before you need to recharge the headphones, always try to avoid letting them go totally flat to deter internal battery damage.


  • Bluetooth mode:

Press and hold the Multi-function button to turn on the headphones and enter Bluetooth pairing mode, this is indicated by an alternating flashing red and blue LED. Open your device’s Bluetooth mode and search for the pairing name “Sonun Y9” and select. If your device asks you for a pairing code enter “0000”. Once paired successfully a tone can be heard and the LED indicator

The headphones will flash blue intermittently. Use the earcup control buttons (2, 3 & 4) to play, pause or navigate up and down your tracklist. Short press MFB  to play and pause the current track, short press button (2) for next track or button (4) for previous track, and long-press button (2) for volume up or button (4) for volume


  • AUX (3.5mm) mode:

Use the 3.5mm cable provided to connect your headphones to any compatible audio source. The headphones don’t even need to be switched on, but the track control and volume buttons won’t work and must be controlled at source using this method.


  • Handsfree calls:

These headphones are also capable of handling hands-free calls from your mobile device whilst connected via Bluetooth. To accept or an incoming call press the MFB button once, to reject it press twice. To redial the last number stored in the phone’s memory (incoming or outgoing) press the MFB button twice while you are not on a current call.

A) Check that the headphones are in pairing mode; Bluetooth is enabled on your device, and the device is set as ‘discoverable’.


Q) The Bluetooth headphones disconnect with my device within the stated 10m transmission distance.

A) The maximum transmission distance stated is dependent on a clear line of sight between the headphones and your device. If there are large metallic objects or other devices transmitting radio or wireless signals in the vicinity, they may impact the reception of the headphones.


Q) The Bluetooth headphones won’t reconnect with my device.

A) On occasion, your Bluetooth device or the headphones may enter a locked state and need resetting. To do this, turn the headphones off, find them in your device list and select “forget this device”. Then, follow the pairing instructions described in Bluetooth mode
