A hat with reflective material that keeps you warm and from which music comes, that is the Bluetooth Music Beanie from Kalinin. Running be put me on!
The elastic hat stretches smoothly from head circumference 55 centimeters to 58 centimeters. Thanks to the wireless connection with your Smartphone, you also listen to your favorite music via this hat. Charging for 2 hours via the supplied USB cable guarantees 5 hours of listening pleasure.
The manual also teaches me how to operate the hat. That goes pretty smoothly. It takes some getting used to the speakers that push the height of my ears, but I forget that quickly, because the sound quality is certainly sufficient. I notice little to no disturbances. An extra asset is the visibility. The hat has two reflective strips and a loop at the back. You may attach a flashing light to this.
