I paced the perimeter of my house and yards and found that the connection began to cut out at around a 65-70 foot radius. Loveeeeee, comfortable great for long walks or small hikes. We have not slammed them. And both pack and buds have lights to show you if and when theyre fully charged. Plugged it in and reassembled the console. For delivery, the company I ordered from was great. But thats not Billys real problem. I l love a shoe that puts good air between my toes. I do have wider than average feet but I can barely squeeze my foot in. My coat closet in this apartment was overstuffed with boots, shoes, gloves, etc.
