We are looking for an individual to help us with selection of microphone/microphone array for our consumer electronics product. The product is used outdoors and is mounted to a helmet. We have 2 designs - one we're using a codec, the other a Bluetooth module (codec built in). We are looking to identify the optimal design that will give us very good quality (good voice pickup and low noise). Ultimately, we need the mic(s), specs, additional components like amplifier identified based on theoretical design - we will obtain product and test ourselves.
