Review on 🎧 Wireless Bluetooth Beanie Hat 5.0 - Winter Knit Hat with Speaker and Microphone, 8 Hours Working Time for Outdoor Sports by Jeremy Lane

Very clear, annoying and possibly hearing-damaging (at higher volume/time of use) electronic hum during audio playback from the left (control) Speaker. When the sound is paused, the beep will last for 10 seconds and then stop. once you continue, the sound will return. As someone who has had tinnitus (tinnitus) for 10 years already, I can immediately say that this is only going to get worse. I suspect it's because the speakers are cheap, but I bought a Pococina cap for the same price and it works great without the odd sound. Who knows, maybe a replacement would work better. Buyer Warning. I can't rate the battery life as I sent it back immediately.
