Query: Great sound - a little scary

I purchased this product to listen to music / watch videos while on my bicycle trainer. My setup requires me to plug it at the back of my computerThe sound is great and the retention mechanism works as advertised.The length of the cable is a little on the short side, but that may depend a lot on the use you plan for your product. More importantly, after working a good sweat I am sorry to report I got shocked. The headphones started buzzing and I felt a minor, but very clear, electric shock. Needless to say, the headphones went flying and have not been used since. People might point out that the likely culprit is my computer, not the headphones. All I can tell you is that the experience was a little scary.
