FAQs

Question 1: Why can't I record properly after connecting to my phone?

Answer: 1. Check if the connection lights on both the microphone and receiver are solid blue. 2. Ensure the microphone has enough battery. Charge it if the battery is low. 3. Ensure that mute mode is off. 4. For some Xiaomi and Huawei phones, update the phone's software (Settings > About phone > System update). 5. For brands like VIVO, OPPO, Realme, OnePlus, iQOO, etc., enable "OTG" and external recording devices: Step 1: Enable "OTG": Settings > Other settings > OTG > On (or search "OTG" in Settings and enable it). Step 2: Enable external device: Go to Settings > Sounds & Vibration > More Sound Settings > Default Recording Device > External Device.

Question 3: Why can't the microphone record with the device's camera app?

Answer: Some phone systems restrict audio permissions for external microphones. Contact the phone's manufacturer for assistance. Try using other compatible apps, as this product works with most apps on the market.

Question 4: Why is the recorded audio volume low?

Answer: 1. Move the microphone closer to the sound source to avoid distortion. 2. Press the volume button on the phone receiver to increase the volume. 3. For brands like VIVO, OPPO, Realme, OnePlus, iQOO, etc., enable "OTG" and external recording devices (follow the instructions in the first FAQ).
