BE Headwear Bluetooth Headset for Universal/Smartphones - Retail Packaging - Black

I use this beenie under my bike helmet on cold morning commutes. The Bluetooth pairs easily and has great sound! Ive only had it for about a month, but the battery life has been excellent. The only negative would be the button locations. They are way too close together and difficult to feel from underneath the beenie fabric. When I think I'm pressing the power button, it's actually the volume. Or vice versa. I'm considering gluing a nub to the power button just to make it easier to distinguish. Overall a great product!

I use these mainly for my snowboard helmet and in the hat when I run in the cold. They are perfect because my ear usually gets pretty sore when I use earbuds during exercise.

I love this hat!

once you super glue a round lego piece on the middle button, these things work great for listening to music, pausing, and answering calls -- and they're nearly 70% less than other bluetooth speakers sold for that purpose. :)
