These wireless headphones are really awesome! The base unit comes with a phono plug to 3.5 mm headphone jack adapter, and then a 3.5 mm headphone jack to left/right RCA audio adapter. The base unit has nice, long RCA cables on it. They are not heavily shielded or anything, but they are on par with a good set of headphone wires.The wireless has worked awesome for me! No static or noise or any interference! I was worried that there might be a slight amount of static due to all of my computer and electronic devices planted only inches away from the Sennheiser base unit. I have not had a single issue at all! Amazing!The headphones have a on/off switch on the left ear cup. It also houses the 2 x AAA batteries (rechargeable ones that were included). The right ear cup has two dials. One for volume, and one to tune the headphones. The volume is fine, no problems. However, I find the "tune" dial to be a little archaic. The base unit itself has a toggle switch that lets you select between 3 channels. I have 3 units, all set to different channels, so I can tune into which ever one I want to at the time, and my brother and sister can too. I would have preferred a similar switch to have been present on the headphones, even though it is easy as pie to tune the signal in, and you have a good wide range where you get superb sound (unlike some tuning devices where you have that magical sweet-spot that is harder than a fruit-cake to get perfect so you don't have static). The headset itself is also a bit heavy, so if you plan on leaning forward with them on, be ready to keep them from sliding off your head. Not too bad, considering they have batteries and all.The price is not too bad! And, being made by Sennheiser, these headphones are great! If you are looking for a wireless headset, I recommend these, unless you are looking to spend MUCH more, or are willing to gamble on quality. I was amazed to find the Sennheiser RS120's at such a great price and such awesome performance!
