User Reviews
6 April 2017

I purchased this microphone to use on a guitar for live sound. Works great for live and recording. It's quick and easy. It has a warm and natural sound. I would purchase another if needed. As with all AT mics I've owned, great quality and value for the price.

I bought this for recording and performing with several obscure African instruments (segaba, karimba, and chipendani). These are instruments with very hard to reach "sweet" spots; normal mic technique did not do them justice. Has met all expectations.

26 April 2013

This extremely small lav delivers great audio, and its diminutive size allows for it to remain virtually unseen in the shot. I highly recommend it for controlled interviews.

the sound of this microphone is warm and it has a good presence in the low medium, It's a complementary solution to other more aggressive products of the market. It can be used in noisy conditions.

I like the clarity. Not quite as compact as I'd hoped, but if you're not trying to hide, it does the job well.

1 May 2012

This is a good lav for the money. It has a nice warm sound and is very durable. We have these all over the studio and they never give us any trouble.

Just what I wanted

19 February 2015

I purchasedd the AT831B to be used as a microphone for live streaming broadcasts. The microphone sounds great and has performed up to expectations.

17 July 2014

Small and out of sight, great quality. Just like The Tuck Pendleton machine: zero defects.

23 April 2012

Just like everyone says... Great sound, affordable price, reliable. I would buy it again in a second.
