Astro has a downloadable app that I can use to adjust thumb-stick sensitivity, and even remap the UL/UR buttons. I have washed them in the washing machine, left to air dry about 3 times, clean up nicely when needed. Ive bought a few pairs of Rainbow sandals in the past because theyre comfortable and they last for years even if they take some abuse. I will say that you have to get used to them. The ZEROs win hands down in comfort; its like soft, leather-wrapped pillows around your ears, and theyre large, but my ears got very hot very fast (and I was wearing them in a ~55-60 degree house). Perfect support for my feet. The Ulele pair was extremely comfortable right out of the box. I wholeheartedly recommend this product! - Connectivity is miles better than Ive had before. Durable, and easy to use, easy to clean.
