How to get Ace 130 into Bluetooth Pairing Mode?

When using two earbuds

For first use

1. Open the charging case.
2. Wait for a few seconds until the LED on the R side flashes RED & BLUE alternately.

For subsequent use

1. Open the charging case.
2. Long press the button on the charging case to get the earbuds into PAIRING MODE - indicating by R earbud flashes RED & BLUE alternately.

Note: R earbud acts as the default master earbud until you use the L earbud standalone with the R one powered off – the master earbud will change to L then. For subsequent use, the L earbud will enter pairing mode, i.e. the master one will enter pairing mode.

When using one earbud

1. Make sure all the previous paired devices are Bluetooth-OFF!
2. Remove one earbud from the charging case only and keep the charging case close
3. Wait until it says PAIRING and LED flashes RED & BLUE alternately

Note: If 3 does not happen, turn the earbud OFF and ON again, wait for 8-10 seconds until it flashes RED & BLUE alternatvely.
