I use one and am very happy with it. Though to get the best sound quality I plug my headphones into the headphone socket on the receiver unit rather than use the loop. You also need to watch out for a very slight audio delay, not an issue if you turn the sound off on the tv, but this is may not be possible if someone is watching tv with you. However, to get around this most modern TVs have a delay option. I have a samsung tv and go to TV, Sound, Additional Settings, SPDIF output (my Sonumaxx is plugged into the SPDIF output) and set the delay to 10 or 20 milliseconds as appropriate. This all sounds very technical but in practice it just takes 10 secs max. Hope this helps
