Panasonic Active Shutter 3D Glasses (TY-ER3D5MA) These came with a Panasonic Viera GT60 plasma back in 2013 ISH. But as far as I understand these are compatible with a wide range of Panasonic TVs from that era - do you own research! These are labelled as Full HD 3D RF. so I believe they are the RF/Bluetooth type not the infrared earlier ones. I can't see a Bluetooth logo though, so again, do your own research! I've replaced both batteries with a fresh new one and the LED power light is active, so glasses should still be working fine. As you can see from the pics, they are basically brand new, no marks, battery corrosion or scratches to the lenses. Listing is for 1 pair, but have 2 for sale.
