when you are 50cm away from the HD300T microphone, the microphone can withstand a 120-decibel cap. (The effect of distance is different) But we need to remind you that long-term screaming into the microphone can easily cause damage to the microphone. If you have any questions about the product, please contact our after-sales team or the official website. The after-sales team will provide you with a corresponding solution according to your problem.
