Forgot to add, I recently bought some Outdoor Tech Chips bluetooth speakers for use in my ski helmet. The damn things lost connection with line-of-sight and about 3ft between my head and my phone in the pocket. If I sat down, they dropped. If I turned my head right instead of left, they crackled and stuttered. It felt like 2002 all over again. Returned, replaced with Sena Snowtalk.
