Two used Astro A50s of two different styles. The black set has a fairly abysmal battery life and the white set stays going a little longer. The white has stains from use that I couldn’t clean out. Both of cloth ear and head pieces that need to be cleaned/washed.
Please note pictures for how cables attached. Highly recommend that you replace them. Two had some cuts from being closed into a drawer, and the yellow ended one was made by myself and worked but is behind to age and tear open. Please see pictures and contact me with any questions. Used for a long time on my Xbox360 and XboxOne using the optical cable.
Outside of battery life they both worked when synced to the base station and sound good still. It’s been a while since I charged and tried them so I don’t have an exact battery life time. The grey USB to micro usb is what we would leave plugged in to get power. There is a kit to replace these batteries but I’m not that good to do it. Seems like a good project to tinker with.
