This is an auction for the Pioneer SE-DIR1000 expansion headphones. These are expansion headphones for a wireless headset I bought a long time ago. When I sold the main unit, I looked for these expansion headphones but couldn't find them. They turned up during a recent move. *Although they worked at the time, I can't confirm their functionality now, so please understand that this is being sold as junk. I tried putting batteries in and checking, and it seems the power turns on (see photo). It's an old product, but if anyone is still using it and looking for one, please consider it. Thank you, and I look forward to your consideration. - Model: SE-DIR1000 - Type: Digital Headphones - Right Side Indication: RIGHT - Features: Open-air design - Ear Pads: Soft cushion
