Review on 🎧 Winter Unisex Bluetooth Beanie Hat with Wireless Headphone Headset Earphone Stereo Speaker Mic Hands-Free - Ideal for Outdoor Sport, Skiing, Snowboarding, Skating, Hiking, and Camping by Oscar Ferrell

Turns out it's a pretty good hat. My expectations were low for the advertised price. However, it is functional and has silent prompts when Bluetooth is on and connected. The audio is punctuated with stuttering without a word note as they are thankfully separated by 150 feet plus the outside walls of the house. Battery life with constant music playback in a quiet office at 33% full load is about 5 hours. The electronics can be taken off for washing and I can imagine that with some work Bluetooth gear could be put into other things like motorcycle helmets, Santa hats and whatnot.
