There may be many reasons for the low volume of Bluetooth headset calls, including microphone blockage, poor signal quality, or volume settings.To solve this problem, the following measures can be taken: 1. Cleaning the microphone hole: When the hole of the Bluetooth headset microphone is found to be blocked by foreign matter, you can use a toothpick or needle and other sharp objects to clean it to ensure its normal operation. 2. Optimize signal reception: if the signal is poor during the call, it may affect the voice heard by the other party.Therefore, try to choose an open place or high place when talking, and avoid using Bluetooth devices in a narrow and closed space to ensure good signal reception quality. 3. Adjust the microphone volume: Sometimes the microphone volume of the Bluetooth headset itself is set too low, which will also cause the call volume to be low.In this case, you can try to increase the clarity and loudness of the call by adding the microphone volume control key on the Bluetooth headset. The following items should also be noted when using Bluetooth headsets: 1. Rain proof and moisture-proof: Try to avoid using Bluetooth headset in rainy days, because the water vapor in the rain may enter the equipment interior, thus damaging the components.At the same time, please ensure that the volume is adjusted to an appropriate level before use to avoid excessive stimulation to the ears. 2. Avoid strong magnetic field interference: The Bluetooth headset in motion should be as far away from the strong magnet as possible, because the magnetic elements in the device will decay over time, and the sensitivity will also be reduced.All of these factors may lead to poor call quality or equipment damage. To sum up, when the volume of the Bluetooth headset is low, we can solve the problem by cleaning the microphone holes, optimizing signal reception, and adjusting the microphone volume.At the same time, pay attention to rain and moisture protection and avoid strong magnetic field interference when using Bluetooth headset.
