Frequently Asked Questions

Q: What devices is this wired headset microphone compatible with?

A: This headset microphone uses a standard 3.5mm audio jack, making it compatible with most voice amplifiers, portable PA speakers, conference systems, and computers or laptops that feature a 3.5mm microphone input. Always check that your device supports a 3.5mm mic input before use.

Q: Does this microphone require batteries?

A: No — this microphone does not have a built-in battery. It operates on a plug-in voltage of 1.5V supplied by the connected device, so there's nothing to charge or replace. Simply plug it in and it's ready to use.

Q: What is the cardioid polar pattern and why does it matter?

A: A cardioid polar pattern means the microphone is most sensitive to sound coming directly from the front (i.e., your voice) while naturally rejecting sounds from the sides and rear. This helps reduce ambient noise and feedback, resulting in clearer, more focused vocal capture — ideal for presentations, teaching, and amplified speaking environments.
