It also beats out the Sony WF-1000MX3, which I purchased on Black Friday but returned after it failed to impress. Literally my favorite sunglasses ever. Si adattano bene lo stesso, si cammina bene Perhaps it would be a good idea to spend a couple of extra bucks and get a new Ooma instead of these factory refurbished units. This is simply my favorite feature of this band. We drove on the highway and it held up even with the high speeds. I didnt notice a significant different in sound quality or volume level, but I am also not sure how much the guard does. Only complaint is that his toes did get little blisters, but they obviously didnt bother him because he wore them every. Shoes were marked 10. I am returning and asking for a refund ASAP!
