This is the ASTRO A50 X. I purchased it last month and have opened it to confirm its functionality. It has been confirmed to be working. I was planning to use it with my PC, but I've decided that earphones are better for me, so I'm selling this. This is my first post in quite a while, so please let me know in the comments if there's anything I've missed. To avoid any misunderstanding, I'll add that I only used it once to confirm its functionality after opening it, and it has been stored in its packaging since then.
