MEET UP MORNINGS NEAR FORT AND COOK This was around $500 new but it’s old technology now and won’t work on smart TVs without an analogue digital converter thing. Smart tvs don’t have a headphone jack. My friend chucked out a lot of the stuff in the box so it works great by just plugging it into the headphone jack on the TV. It has 2 batteries installed, one is in the headset and the other is in the base charging, you switch them when you need to. Listening time is long, I don’t know, maybe 10 hrs or so. The batteries last at least a few years I think. When you set the headphones back on the base it recharges. It cannot overcharge. Really great for hard of hearing folk. When the headphone jack is used it cuts out the TV speakers so it’s good for a single person! . I see little RCA type cords but I don’t know how they work, I couldn’t make that work but it does work well in the headphone jack. Here’s the manual but you just plug into the wall with one cord and the headphone jack with the other so you don’t need the manual as it’s just the headset base and 2 cords for connection! https://assets.sennheiser.com/global-downloads/file/6630/Set830TV_Manual_08_2016_EN.pdf
