The score is 4.5 -- rounded to 5. The latest comfort, quality, and ease make the RR5200 a true replacement or an add on -- for a tad price. I'm glad to own the RR5200 headset/receiver that works well/seamless with the TR5000 transmitter/charger. Sennheiser seems to really listen to previous customers on making vast improvements -- pulling out no stops. How to sink: first, just place RR500 headset/receiver on TR 5000 transmitter/charger for six hours. Next, wear RR5200 headset/receiver and turn on TV to check/hear audio, just make sure TV audio setting is set to PCM; Blu Rey player audio setting needs to be set to PCM, too. Finally, while wearing the RR5200 headset/receiver, press the volume up and volume down on headset at the same time -- this will ultimately sink RR5200 with the TR5000 (which blinks for confirmation) -- for the purist of perfection. Enjoy

This works beautifully. We bought it because we needed two headset receivers and the 5200 only comes with one. This receiver also came with an instruction booklet for the entire 5200 system, which helped a lot because the 5200 system did not contain any instructions beyond a "quick-start" type of guide!) . The 2000 had no instructions for that, and fortunately I was able to find them online. The 5200 had instructions but they did not work; again, the online instructions did the trick. I had one issue with the extra receiver. Extra receivers need to be paired with the original system, which was not mentioned until somewhere late in the instruction book (after I was convinced that the extra receiver did not work!). However, the instructions for pairing in the booklet did not work; fortunately, I was able to find accurate pairing instructions online.
