i walked around my large apartment and didn't notice any drop-outs until i got close to my wifi access point, which also operates on 2.4ghz.
the frequency that it uses is way better then infrared because you can walk anyone in your house and not have to be in the line of sight.
sony provides an option to mate that headset to this base and avoid running extra cables or daisy chain them together as each base also has an optical output jack.
but when i get up an and walk i can go everywhere in my 1 bedroom apt and hear just fine.
these go well with my sony core mp3 player.
i use these at the gym and find them to be comfortable, sturdy and compace\.
i take these to the gym every day and they easily collapse to fit in the pocket of my sweatshirt.
