Notice: Please turn on the amplifier for about 15 seconds before you connect the audio source and put on the headset. We recommend using 24~600Ω headphones, while armature earphones and headphones that have low resistance and high sensitivity are not suitable. As there will be tube Microphone effect, please keep the amplifier steady while using it. For noise issue, please keep it away from devices like routers, mobile phones or something that may interfere in the audio signal. If there are no interference, please remove all input and listen to see if the noise still exists. If so, the device may be defective and you can contact us to get support.
