The product is a rare replacement magnetic earpiece for the Astro A40 headset, specifically designed for the PAX West 2017 edition. It features a black color and comes in a pair of earcups with a headband form factor. The wireless technology is infrared, with a 7ft cable length and a 3.5mm jack connectivity. The earpieces also include a built-in microphone for convenience. Perfect for those looking to replace worn out or damaged earcups on their Astro A40 headset. There is slight damage to the plastic case but it’s not bad (see last picture) (I do not see any of these on the market at the moment and I haven’t seen any sold recently either, so these are the only ones for sale!)
