Lenovo x4 bone conducting headphones

So after all the hype and crazy pricing is over, I decided to get a pair of Bluetooth bone-conducting earphones.
The idea is, that instead of speakers, these headphones have some sort of coils that supposed to resonate your jaw to make sound.
I like the concept that it leaves your ears open to be better aware of your surroundings.
I also like the low weight and the nice battery life .. and its very quick and easy to put these on, as opposed to my True Wireless JBLs, which take much longer to put on and adjust.
However, there are some limitations to these.
The overall volume level is relatively low and makes these unsuitable for noisy environment.
The sound is not very discrete and can be easily heard by others.
And the Bass is pretty weak.
Also, the touch button is too smooth and hard to find and it often being pressed by mistake.
And.. There’s a constant vibration on your face when you listen to music.
