Review on OKCSC Bluetooth Intelligent Waterproof Microphone by Eathan Wilson

So for some reason you can only use the left ear, the right ear can only be used in combination with the left. So if you intend to double the battery usage, use it one earbud at a time, you are deeply mistaken. The other problem is that the touch design works, but you just have to pierce your own eardrum in the most painful way possible. as expected for wireless Bluetooth, i.e. at eye level. I just can't/use them the way they are.
