We used this for my sons Astro a40 headset. I just ordered my 4th pair. It seems like most of the gadgets I use these days need the same type of charger: Phone, tablet, ebook and even my toothbrush! Great deal so far, hopefully it lasts longer than 2 weeks. Martens site instead of Amazon. I had sore feet a few times after wearing longer than an hour on my feet. But the car is the same and the packaging was nice. For audiophiles, the choice might be harder. I am normally a size 8. Theyre perfect.
