It's good for laptop or pc bug your phone.. Mehh..

I love the quality of cable and the sound. It increases the sound stage and clearity of your iem a lot. It just makes you like them more. I would have loved to give 5 stars but don't know why it works fine on my latop and pc but on my Android phone it some time gives a hissing and popping electric sound. It eventually goes away but it just annoys because it comes after some time again. I don't know if it's something wrong with cable or my phone otherwise a great product.

Thank you so much for taking the time to leave us this review.
