If you want to listen to music using your i7s tws headphones, you need to make sure that both earbuds are connected. This is necessary so that you can hear the music clearly and not get any ear fatigue while listening to it.
Connecting the Headphones
You should first turn on your i7s tws Bluetooth headphones by pressing and holding their power button for about 3 seconds or when the blue light is on and also prompted by the “the power on” voice. You should then follow the instructions in your user manual to pair them with your mobile device.
Reset the i7s TWS Earbuds
If the earbuds do not work after a while, you can try resetting them to see if they are working correctly. There are a few different ways to do this, including using a micro-USB cord and resetting them through the Bluetooth menu on your phone or tablet.
Unplug them and then place them in the charging case (they should be in the slot). Leave the lid open for a few minutes to let them charge and reset.
Plug them in again and this time they will be ready to use. You should be able to pair them with your device by following the same steps as before but now you will need to search for their names in the Bluetooth menu on your phone or tablet.
Reset the Volume of your i7s TWS Earbuds
The i7s tws earbuds have a multi-function button that allows you to change the volume on either earbud. Press the multi-function button on one earbud to decrease the volume, and then press it again to increase the volume.
You can also press the multi-function button on both earbuds to answer or reject calls. You can short-press the buttons on either earbud to hang up calls and long-press them to reject calls.
Reset the Language Modes of your i7s TWS Earbuds
In the Chinese mode, the flash will glow red and blue when you press and hold the multi-function button on each earbud for about 3 seconds. This will then be remembered for future pairings.
How to Change the Language Modes of your i7s Bluetooth Earbuds
The i7s TWS headphones will enter the language pairing mode when the flash glows red and blue, and you can change it by press and hold the multi-function button on both earbuds for about 3 seconds. This will then be the default language setting on your i7s tws.
You can also change the language on each earbud individually by double-clicking any of them. This will change the language on each earbud to the same language as your phone.
