Frequently Asked Questions

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

A: This microphone uses a standard 3.5mm jack, making it compatible with most voice amplifiers, portable PA speakers, karaoke machines, and conference devices that feature a 3.5mm microphone input. Always confirm your device supports plug-in power (1.5V) to power the electret capsule.

Q: Does this headset microphone require batteries?

A: No — there is no built-in battery. The microphone draws its operating voltage (1.5V) directly from the connected device via plug-in power through the 3.5mm jack, so it's ready to use straight out of the box.

Q: What is the benefit of a cardioid polar pattern for speaking?

A: A cardioid pattern captures sound primarily from the front (your mouth) and rejects noise from the sides and rear. This makes it ideal for presentations, teaching, public speaking, and conferences where you want your voice to be heard clearly without picking up excessive room noise or feedback.
