Buy microphones


Micbooster make microphones based on the excellent Primo capsules. They have the best quality for the cost available, we think.

You can also buy microphones from us. 
contact@soundtent.org
grant@soundtent.org
We use very good cable and connectors, which may make our microphones more resistant to EMI. This can be relevant for broadcasting / streaming.  Our microphones (and streamboxes) come with an indefinite commitment to replace, repair and/or help with any issues you encounter.

MICROPHONES

The Primo EM272Z replaces the legendary Primo EM172! They seem just as good. The PUI is a cheaper alternative, which gives more tolerance for learning. They also sound excellent, and work particularly well with the IQ Audio Codec Zero for running live streams – maybe better than the Primo’s. Otherwise, they may lack some detail and refinement, but opinions vary.
