NOTED: This product is a Bluetooth-compatible receiver (non-Bluetooth-compatible transmitter), which is generally wirelessly connected to Bluetooth-compatible devices such as mobile phones and tablets, and wiredly connected to speakers or headphones without Bluetooth-compatibletooth, and converts it to have Bluetooth-compatible function. Q: The sound is not clear when the volume is too low or too high. 1. when the volume is too high: Similar to A-ndroid phones when using headphones it will warn you with a beep when you set the volume beyond what the World for Health Organization considers safe for headphones use. 2. when the volume is too low for you to hear, it may affect the quality of the sound you hear. So we are not recommended to adjust the volume of the speaker or mobile phone to the maximum or the minimum, which may damage the hearing and sound quality. It is best to adjust to moderate and not affect the hearing effect. (For better sound quality, please also adjust the volume of your device.)
