Why can't I get sound in from my headset mic?

Applies to: all audio interfaces

We have had many users enquiring about using 3.5mm headset microphones like these, with our interfaces.

While these can physically be plugged into the combi-XLR inputs on our interfaces, they have power requirements different to that of standard microphones that connect via XLR. These headset mics that connect via TRS 1/4" jacks are primarily intended to be plugged into the 3.5mm mic inputs on computers and thus, have very low power requirements (normally around 5-10 volts).

Standard (condenser) microphones on the other hand require 48 volts of phantom power to operate, which is what our interfaces and all other standard audio interfaces with mic inputs, provide. 

We are aware that there are some 3.5mm female to XLR male adapters available on the market that step down 48 volts to around 5-10 volts, that the headset mics can make us of. We can neither recommend nor confirm the compatibility of any such adapters for mini microphones when used with our interfaces, as we have not tested any adapters.

We would like to point out that our interfaces (like other standard audio interfaces), are designed to be used with standard dynamic/condenser/ribbon microphones that connect using XLR cables.

If you have any further questions regarding the compatibility of headset microphones with our products, please contact our Technical Support Team.
