I bought the model ATW-2192 now discontinued, superseded by the newer model ATW-2192A. I don’t like it. A little drop-out here & there. Not a lot. It’s mediocre at best, and more susceptible to feedback. I don’t know about the newer one ATW-2192A if there’s an improvement.
I returned it after couple of weeks, replaced it with a Countryman E6 with Shure ULXP Receiver. ($800 on sale).
I love this headset. It’s comfortable & nearly invisible. I can shape it the way I want to fit my head perfectly. So lightweight I forget I’m wearing it. Voice pick-up is very good. Plus, I can hug the ladies left or right side without taking the headset off.
If you decide on a Countryman, don’t get the omni model. Get the directional. It has more gain before feedback.
