I ordered this item (S1D TWS) on 21 July. It didn't arrive. I have emailed 4 times to various addresses at KZ but not received a reply. So finally I'll leave my review. I am disappointed, to say the least. KZ have asked for my review thus think (or thought) it had arrived. I have emailed 3 times since that review request. Is no-one there? Not a peep. Suffice to say I am mightily disappointed with some extremely poor service.
Everything works as it should
I really liked these headphones. For 1.5 K good sound and they came to my ears that for me a very big problem.
Good product! Ok sound quality for the price.
