Product Q&A

Q:Does the kit include a power supply?

No, the kit does not come with a power supply. You need to buy a 3V power source separately from our store.

Q:What should I do if the headset screams when powered on?

Do not put the headset in your ear. Adjust the potentiometer until the screaming stops, then put it in your ear and adjust until the sound is clear.

Q:What is the recommended welding order for components?

Components on the board should be welded from small volume to large one.

Q:What happens if specific components like resistors are out of stock?

We will send components with nearby values instead. For example, blue metal film resistance may be replaced by gray carbon film resistance, which has the same effect.

Q:Does the seller provide welding assistance or guarantee success?

We can help check problems if welding fails, but we cannot guarantee successful welding as errors often occur due to wrong component placement.
