Thank you for viewing. This is a listing for the Astro MixAmp Pro TR unit only. I haven't used it for 5 years, and I have no way to confirm its current functionality. I used it for FPS games in the past, so I think there might have been some settings that made certain sounds, like high-pitched noises, more audible. Please initialize it before use. I have only confirmed that it powers on when plugged in with a charger. Basically, I hope you will purchase this assuming it's a junk item. However, if it's completely unusable upon arrival and you wish to return it, I will accept returns, but the buyer is responsible for the return shipping costs. In that case, please contact me before leaving feedback. m(__)m
