Sound Booster uses the microphone of your device to pick up sound and then wirelessly transmits the sound to a Bluetooth headset so that people with hearing impairments can hear more clearly or to a Bluetooth speaker for it to be played more loudly.

Application scenarios:

• When watching TV together, give a Bluetooth headset to an elderly person with a hearing impairment and then place your device below the TV set to pick up sound and transmit it to the Bluetooth headset.

• In a noisy environment, use your device as a microphone and connect it to a Bluetooth speaker for sound to be played more loudly.

1. Connect your device to a Bluetooth headset or speaker.

2. On your device, go to Settings > Sounds & vibration > Sound Booster to enable Sound Booster. Touch the device you want to connect to.

3. When connected to a Bluetooth headset, place your device near the sound source. When connected to a Bluetooth speaker, hold your device and speak into the microphone.

4. Wear the headset or place the speaker in an appropriate position. Make sure the distance between the speaker or headset and your device does not exceed 10 m (about 33 ft.).
