Thank you for viewing. I used it once after purchasing. It can be connected to a smartphone, etc., and used as an external microphone. It can also be used for ASMR! I am selling it because I no longer use it. [Driver-Free Plug and Play USB C Microphone] - No additional power or drivers are required. Simply snap the microphone on, and you can easily record on the go, capturing better audio quality than the built-in microphone of your USBC device. [Hi-Res ADC for Professional Recording] - The built-in high-resolution ADC supports 48 KHz/16-bit studio-grade sound quality and cancels out unwanted ambient noise. [Crystal Clear Sound Quality] - Adopting a high-sensitivity omnidirectional ECM unit, it picks up loud and clear sound from all directions, meeting all your recording needs. [Hands-Free Clip Design] - With the collar clip, you can clip the MIC to your shirt collar or buttons, freeing your hands when recording for your YouTube channel or vlog. - Model Name: MLC-1 - Connection Type: USB-C
