Great lapel for the price. The squelch is a nice feature to help get rid of any static noises or outside frequency interruptions.

We used this for in house video. Far better than camera Mic or zoom built in mics.Connected to base nicely. Will pickup clothing noises and breathing if record level too high.Good quality for this level of video shooting.

The audio quality is amazing with this product and the ability to scan for open frequencies allows for no interference.
