I got the Model 3 (single driver) about two years ago. Good overall build quality and the sound is great for the price.
Backed 2 pairs of their first TWS model and those were a little dissapointing. Charging did not work for the left pod from the start and i ended up returning them. Year later the second pair developed same issue.
Nismo Jr. I use for teams meetings on the road but they are very uncomfortable and i can't get a good seal with any tip size.
I also have the TWS ciem's and been very happy with those. Actually i haven't seen any other tws ciem's on the market.
That's my experience with ADV products so far.
I know next to nothing about this company. I believe they crowdfunded their first product, but never heard anything after that. I would love to know more, if anyone has the 411.
Picked these up from them about a month ago. They are well worth the price. Very comfortable and the mic quality is great. The cooling pads actually work and are not a gimic which was nice.
Overall they are a great value and would be an excellent replacement.
They are definitely bass heavy, typical of more gaming headsets. The audio positioning and imaging is great for the price imo.
