Review on Headphones 1MORE Quad Driver In-Ear E1010, grey by Kichiro ᠌

If you connect it to a laptop that is charging (mbp 16 ”in my case), then periodically the left earpiece is shocked. It appears as a slight tingling sensation. The manifestation of this is also affected by the shoes in which I am, and the surfaces that I touch. Yes, the laptop is not grounded, but, nevertheless, I do not think that headphones for this amount should have such problems. Using external DACs between laptop and headphones does not solve the problem.
