1 Voice Wireless Bluetooth Earphones

Anyone have any info on these? I can’t find a thing on them. From what I have seen/read, most totally wireless units just don’t work that well.

This is the only thing I have found (the battery only last 3.5-4 hours, if that). There are no reviews of the product anywhere. https://www.tomoson.com/promotions/view/wireless-bluetooth-headphones-1
