Professional USB Condenser Microphone

Online meetings, podcasting, Twitch streams, YouTube content - you can do it all and much more with cosMik uCast.

This USB microphone combines ESI's characteristic outstanding sound quality with a bundle of powerful software so start recording or streaming straight out of the box.


Perfect control

cosMik uCast can be connected to any modern Mac or PC using the included USB cables (USB 2.0 and USB-C). It also works seamlessly with your iPhone or iPad with an appropriate adapter.

The cardioid polar pattern captures musical details, harmonics, and subtle nuances crystal clear, while background noises from behind the microphone is nearly inaudible.

Controll your sound with the help of user-friendly knobs on the front of the mic. You can adjust input gain and output volume for the headphone output seamlessly or mute your own voice while still hearing the computer signal. Realtime hardware input monitoring can be controlled via the included software.


As a podcaster or content creator you often need to record your voice and edit or master your track before providing it to your audience. With cosMik uCast, there is no need to look for external software, because it's all included: WaveLab LE for audio editing, Bitwig Studio 8-Track as a multitrack digital audio workstation (DAW), inTone 2 ESI Edition to play files and prepare streams for online broadcasting as well as Cubasis LE, an optimized multi touch sequencer for iPad and iPhone users.

Live broadcasting

Enrich your live streams on Twitch, Facebook or Instagram: the ASIO driver based on ESI's own EWDM technology guarantees extremely low latency, so you can interact with your audience immediately. Moreover, the ESI-only feature DirectWIRE enables you to integrate external sound sources in your live performance (e.g. background music or effects such as laughter or applause). You can even run your voice through a DAW and alter it in the process (e.g. a reverb or other effects and plugins).

Online meetings and more

The DirectWIRE technology can help you to avoid feedback in your online meeting on Zoom or Skype. By using the DirectWIRE virtual channels, it is possible to separate the signal that is being played out on the monitors from the streamed signal. Unwanted mixing and feedback can be eliminated completely.

The ASIO driver and the DirectWIRE feature can be used with any modern Windows PC. Users of a Mac benefit from the plug & play experience and mobile users of an iPad or iPhone have even access to the powerful Cubasis LE App.

Included accessories

cosMik uCast does not only come with the cables needed to connect it to any USB 2.0 / 3.0 or USB.C (3.1) port of a modern PC or Mac, it also includes a tripod table stand and a microphone holder clip which helps to mount it to a common microphone stand.
