As I bought the really expensive Airpods and had them fall out on my first run I was desperate for anything that worked. Luckily for me AhaStyle Earbuds work perfectly and means I no longer worry about losing my awsome Airpods. Arrived quickly and have nil complaints.
My wife is very happy in the way it fits and does NOT fall off. Also (after a little bit of trial and error) she can hear music on both the ears and the sound seems to be pretty decent. Happy with the product.
