Initially, I was fully expecting there be a significant ?trade-off? in performance, particularly with a more budget-minded model of earphone, but after week or so of playing, I am yet to really find it. It?s cute, I?ll give you that. COOL. I use this to power off my chest freezer which I have converted into a beer/keg fridge. Really expected more from this brand, very disappointed I had registered my Trekz Air to the Aftershokz warranty website the day I received the product, and when I placed a warranty claim, Aftershokz allowed me to receive a replacement product after I had sent in my old Trekz Air headphones with a shipping label provided by the company. 5 or 1 in childrens shoes. But it is distracting. None of the holes in the cheap plastic brackets were correct allowing you to put together. The only thing Id like to see, is to have an option without hook on the side.
