As they say "if it aint broke, dont fix it". first pair I have ever owned. Edit on July 14, 2019:Its been almost a year since Ive bought this bag. Bottom line, I like the look, simple operation, very identifiable lighting when you are on mute - and most importantly, the sound - AMAZING. After our last trip with lots of walking, I came home with mild plantar fasciitis, and I was NOT going to have that again. Gifted this to a friend of mine and got only positive reviews from her. When ear plugs are used (a pair is provided with the Aftershokz) the base returns, although it is a little muddy. Other than that, it works very well! Finally the fix Ive been looking for! I got no compensation for my reviews.
