The microphone is built into the speakers like many other Uclear models. Installed correctly, they work reasonably well. There’s an upgrade speaker that puts small mics in the brow of the liner and they work better.
I run Uclear exclusively in my helmets currently. I think they sound good and work well. I like their pricing as well. Are they as good (well before this new model came out) as high end Sena and others? Probably not but they do all the same stuff and cost way less. I haven’t found anything lacking in features, and it’s easy to move the unit from helmet to helmet once you get an extra pair of speakers. If you need to do a lot of talking or recording videos, something with a boom might work better, but I rarely need that so they work great for me on all incoming audio sources.
