DrueMetal shells will electrocute you if you have bad grounding on the source device. I have that problem with my Tin Hifi T2 Pro's on Lenovo laptops when they are charging but not on my Dell.
QwervyUsed many different sources and it's the same issue on all of them. It's also unacceptable for any consumer product to electrocute you no matter what the end user is doing. It is poor engineering at best. There is no excuse.
Drueyeah really. I was planning to buy P1, but read quite a few comments in Drop - folks who bought it and could not get a replacement. So, dropped the idea.
