These cans are fantastic - great sound quality (big 50mm drivers give a full frequency response and BIG explosions etc. in movies). They have excellent range and the 2.4GHz wireless means you can put the transmitter wherever you like and not have to worry about being 'line of sight' as you do with IR cans. The downside to this unit over the previous model is that they work on the same frequency as other wireless devices (such as my XBOX) - the two interfere with each other so either the headphones keep 'clicking',... hunting for new channels or, occasionally, the XBOX wireless controller shuts down saying signal has been lost. So.... few issues for gamers but great for late night movie buffs.
