Got this BT earpiece for use on my old car without BT function. It works great function-wise, no problem connecting to my iphone 7p at all. It's larger and heavier than AirPods, that's because it needs larger battery to support longer listening time and standby time. If recharging a couple times a day won't bother your daily life, you can go ahead and get the lighter ones. But, if you need to spend hours driving or it's more convenient to use earpiece for longer time, this one is a good choice. One thing that I think to be improved is that it needs to be redesigned to accommodate people with larger ears. I believe that a certain percentage of adults, especially male adults, might feel it doesn't fit quite well on their big ears.
This is the only thing that I think needs to be improved on their future versions. Other than that, I have no concerns.
