Overview

Before First Use

Even though your InSound earphones will come with some battery charge, it’s advisable to fully charge them before first use. Connect the power-case and earbuds to a suitable USB power source and leave for around 2 hours to ensure they are ready for first use. When charging, the power-case charge indicators will flash white in sequence to show how much charge is in the case. The more LED’s lit means the more the case is charged. When fully charged, all 4 indicators will be lit.

Pairing in True Wireless mode

On first use, you need to pair the earbuds to each other and then your device, this procedure will need to be repeated every time you pair them with a new device. Simply remove the earbuds from the power-case and they will automatically enter pairing mode and the LED indicator will flash red and white on both earbuds. Once they have paired with each other, only the right (master) earbud’s LED indicator will flash red and white and you will hear a voice message saying “pairing mode”, to indicate they ready to connect to your device. Open the Bluetooth device list on your phone or tablet and search for the pairing name “AV:Link-InSound” and select. If asked for a pairing code, enter “0000” and your device should then connect with the earbuds and produce a voice message saying “connected” as confirmation.

Play/pause
Each earbud has a multi-function (MF) touch button which is located on the top outside surface of the earbud (see above diagram). To play or pause the current track, press the MF touch button on either earbud firmly once.
Increase/decrease volume
To increase the master volume, press the MF touch button on the right earbud twice and to decrease the master volume repeat the procedure on the left earbud.
Next track/previous track
To move to the next music track, press the MF touch button on the right earbud three times and to move to the previous track repeat the procedure on the left earbud.
Voice assistant
To activate your device’s in-built voice assistant (Siri, Alexa etc), press and hold one of the MF touch buttons for around 3 seconds then release. You will hear a beep sound prompting you to give your voice command. You can then ask anything you want the device to do, such as tell you the weather, move to the next track, play a specific track or album or even find your way home using maps. NOTE: This function is only available on compatible Apple and Android devices, check your device’s handbook for more information.
Turning the earbuds on and off (auto and manual)
To turn the earbuds off whilst they are connected to your device, simply remove them from your ears and return to the correct ports in the power-case.
To turn the earbuds on again, simply remove them from the power-case and they will switch on and automatically pair with the last connected device, providing it’s within range and Bluetooth is turned on. It’s also possible to manually switch the earbuds on and off without inserting them in the power-case. To turn on, press and hold the MF touch button on both earbuds until you hear the power-on sound then release. To turn off, simply press and hold one of the MF touch buttons until you hear the power-off sound then release.
Hands-free operation
When you receive a phone call during audio playback, a ringtone can be heard in the earbuds. To accept the call, press the MF touch button on either earbud once. To reject the call, press and hold the MF touch button on either earbud for around 3 seconds then release. When you have completed the call, hang up by pressing the MF touch button on either earbud once.
Charging the earbuds
To charge the earbuds, carefully place them in the corresponding magnetic ports of the power-case so that the charge indicators on the case light up and the earbuds light up red. When charging is complete, the LED indicators on both the earbuds and power-case will go out. It usually takes around 1 hour to fully charge the earbuds from ‘flat’.
The power-case
The power-case is a compact, magnetic carry case and power bank, with capacity to fully recharge the earbuds up to 3 times. To charge the power-case, connect it to a compatible USB power socket using the charging cable provided. When charging, the power-case’s white charge indicators will flash in a sequence to show how much charge is in the case. The more LED’s lit means the more the case is charged, when fully charged all 4 indicators will be constant white. NOTE: It’s important to always keep the power-case charged to avoid the issue of losing the ‘auto power on and off’ functions of your earbuds.
Resetting the earbuds
Should you wish to reset the earbuds and unpair them from your device, press and hold the MF touch button on both earbuds at the same time for around 5 seconds, then delete them from your device’s Bluetooth list and start again.

  1. I have used these headphone for sometime, and when i put them in the case thinking that they will charge, only when i go to check the earbuds in my ears and look on the phone Samsung note, it says it is only 30% charged when i know the unit is charged up, rather annoying. Do i need to do something, as I cant use them when they have been on a full charge for hours on end? yet says only 30-40% sometimes.
