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.
I selected this mic to use with the System 10 Pro , just purchased. Sound for a Presenter ! Very, very Good - Excellent !
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.
i am a legal video specialist and need a rugged wired mic that rejects background noise and delivers clear crisp speech. I have used the AT831b for nearly 20 years, and they get dropped, abused, yanked and spit on and give many years of good service.
Small and out of sight, great quality. Just like The Tuck Pendleton machine: zero defects.
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.
Used to pick up audio from witness at video depositions. 100% reliable and sound quality good.
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 like everyone says... Great sound, affordable price, reliable. I would buy it again in a second.
