I just bought a Sennheiser RS 180 wireless headphone. I was looking forward to listening to music wirelessly from my Mac, which is connected to a DAC > Amp, and controlling it with my iPod touch in different parts of my home. 
 
Alas, there is a very loud hiss on the headphones; which, considering that the many reviews I've read say doesn't exist, is surprising. I've tried turning off all my other wireless devices - wifi and phone - and the hiss is still there.
 
I would have like to contact Sennheiser to see what they suggest, but they don't offer any support (I'm in France; this may differ in other countries). 
 
Before I send them back to Amazon, are there any suggestions as to what I should look at to get rid of the hiss? Has anyone else had this problem?

Make sure you find a good match between the source volume and headphone volume.
Try to turn up or down the source volume and adjust the headphone volume accordingly.
 
Even with digital transmission, finding a adequate source volume is still the key of audio quality for wireless phones.

No, my source is clean; with other headphones, there's no noise.
 
Altering the volume did alter the level of the hiss, but at normal volume, the hiss was notable.
