Hi,
With the question about the Clarity Aloft headset.... I found the lead quite long but you can coil it up quite easily or get it shortened by someone like Headset services and also have a heli plug fitted to save the bulk of an adaptor. It comes with a couple of plastic crocodile clips for your shirt to stop the cable tugging the back of the headset down or you can use them to tidy the cable where necessary. I really can recommend these headsets so if you get one let us know how you found it in the R22 (it'll definately be quiet enough in that machine).
