If they stop making this kind - I?m sunk! it did not line up with the bottom piece and it kept coming off. However, once I started using it, I had overheating problems with both the pad and the phone (both got really hot), and I swore off wireless charging for fear of a fire hazard. I prefer male vocal on the hd600 because it sounds fuller, and I prefer female vocal on the Ety because it sounds sweeter. I was so impress that I even forgot to remove the plastic cover -_-5 stars. I had a problem with one side falling out but once I changed the tip size they fit much better. Works great and is very accurate, the only problem is I cant get it tight enough in the tracks of my DeWalt saw but in all fairness the problem is more with the tolerances of my saw tracks. It had left some permanent abrasion on the Airpod case itself somehow and now cant be wiped off. recommend purchase ! Love the simplicity of these slides, as well as the comfort and fashion.
