now if only they made a wide sandal my shoe collection would be complete :P I have never used a powerful callus remover before buying this. I LOVE THESE! They play a long time on one charge and have a great range. Ive travelled with it, moved apartments, and I admit I havent been all that gentle with handling it on a daily basis, so I can definitely see how the electronic cables in the mic could be getting worn at the hinge from so much up and down, brash movement. (great for DD tables). -The way this sits around your neck, the controls hang upside down with the +volume button being at the bottom. Happy with my purchase ! This insert will fill up the shoe or sneaker near the toes and push the foot up into the top of the shoe. Even still, overall a great product.
