Sennheiser RS 120 Wireless (RF) for $60

If you are looking for RF wireless headphones (not bluetooth), the new condition Sennheiser RS120 with a 2-year warranty is on sale for $60 with free shipping and free returns at Groupon Goods. The free returns are handy because there are a couple of potential issues with this, the way the AC input connects to Base is wonky and the audio times-out quickly when there’s silence. The Base has to be connected to AC, while the headphones need two AAA batteries (either the included set or your own). The headphones only work with the Base, you can’t use them as a normal 3.5mm input headphone.
