Switching on and off the device

The LED indicator (6) keeps flashing white while the headphones are on. Press and hold the Multifunction button (2) for 2 seconds to switch off the headphones. You will hear a sound when you switch them off.


Auto power off

To optimise battery life, your headphones turn off automatically after 5 minutes in Bluetooth® search mode, if not synchronised with any other device.


Charging the battery

When the battery level is below 10%, the LED indicator (6) starts flashing red. When the battery level is below 2%, you will hear a sound to remind you to charge it.

The LED indicator (6) lights up red while charging the device and turns off once the charging process is complete. To charge the battery, plug the USB Type-C end of the provided USB cable to your headphones' USB Type-C charging port (7) and the other USB end to any device with a USB charging port (PC, USB wall charger, car charger, etc.). The charging time is approximately 2 hours.

Note:

  • To optimise battery life, do not store or leave the device completely discharged for a long time.

Caution: Do not charge your headphones with fast charging adapters or dedicated laptop charging adapters, Because their output voltage exceeds 5V and the device may become unusable.


Bluetooth® wireless connection

Press and hold the Multifunction button (2) for 2 seconds, until the LED indicator (6) starts flashing white. Your headphones are now ready to be paired with your Bluetooth device. Once Studio Plus/Power Radio Headphones appears on your source devide screen, press "connect". You will hear a confirmation sound when both devices are paired.

Once your devices are synchronised, you can control basic playback functions such as turning up/down the volume and skipping to the next or previous track directly from your headphones.

Press Volume + / Next (1) to turn up the volume or Volume - / Back (3) to turn it down. You will hear a sound when reaching the maximum volume level.

Press and hold Volume + / Next (1) to skip to the next song. You can also press and hold Volume - / Back (3) to skip to the previous track.

Press the Multifunction button (2) once to pause or resume playback.

Note: If you're using the audio cable instead of the Bluetooth wireless connection, you will have to control music playback from your music player and not from the headphones.


FM radio

Press Change function (4) and select radio mode. Press and hold Change function (4) once again to start searching for FM radio stations. The process may take a few minutes. Once the search has been completed, press and hold Volume + / Next (1) or Volume - / Back (3) to select the radio station you want to hear from all saved radio stations.

Your Studio Plus/Power Radio Headphones save the last selected radio station when you turn them off. This way you will hear it when switching on the headphones once again.


Micro SD player

Play .mp3 and .wav files from Micro SD cards (up to 128 GB). The contents play automatically a few seconds after inserting the storage unit.

The track you're listening to will be saved to the internal memory when turning off the headphones or removing the storage card. If you connect the same removable storage unit once again, playback will resume from the last track you listened to.

Press and hold Volume + / Next (1) or Volume - / Back (3) to switch to the next or previous track.

The folders and files stored on your removable storage units will be read in chronological order.

Press and hold Change function (4) to move to the next memory card folder.

Press Change function (4) twice to enable shuffle mode. You will hear a "beep" indicating shuffle mode has been enabled. Press the very same button twice to disable this mode. You will hear two "beeps" indicating that this mode has been disabled successfully.


Call control (hands-free function)

Once your headphones are paired with your smartphone via Bluetooth connection, simply wear the headphones and answer calls with the built-in Hands-free microphone (8).

Press the Multifunction button (2) to answer an incoming call. When receiving a call, the song you are listening to stops and the ringing tone sounds instead. You can also press and hold the very same button for 2 seconds to reject a call.

Press the Multifunction button (2) once again to hang up. Playback will resume from where it stopped.

The built-in microphone is designed to answer conventional phone calls from the smartphone. If you intend to connect these headphones to your Windows PC or MAC and use them for home office purposes such as video calls (Teams, Skype, Zoom, etc.), we recommend purchasing this add-on specifically designed for optimal performance: https://www.energysistem.com/headphones-microphone-1-45265-en
