It worked great!

It was exactly what I needed. After ordering the incorrect item and having a great experience returning it - and I'm sincerely saying great experience - I chatted online with a service person and they told me exactly what I should order. It is perfect.

Part missing. B&H unwilling to help.

The mic is fine. However, after receiving the package, there was no clothing clip included. Contacted B&H and they suggested I contact the manufacturer. Bad form.

Replacement Audio Technica microphone

Microphone works well and is a good replacement. Image shown not representative of mic received. The tie clip mic holders are different. Would have preferred the tie clip shown but can work with the one received, thus only 3 stars.

I used this mic for pastors officiating weddings and other public speaking events. Excellent gain before feedback. I would recommend this highly over the AT829CW. Minus one star for flimsy cord. Take care wrapping it and handling it and it will perform great.

I have a TV show with wired versions of this lav. I went to wireless for one mic, and it worked exactly like it should. Excellent.

question

I need to practically swallow the 831cW for it to pick up my voice. Is there a omni-directional mic that would work better? What am I doing wrong here?
Asked by: Anonymous
We have not had that issue with our mic , it was purchased as an upgrade from the mic that came with our wireless unit. It was a big improvement . It has always been clipped on tie not the lapel. Cables are very sensitive on all units we have used so don't wrap them. A lot depends on receiver position & how much power you have for system.
