That's odd about ruthenium. Ultrasone claims they have the safest headphones. Perhaps there is a way to treat it to make it safe?

IMO- I would describe the ultrasone as a open sound- not surround. You might want to try the pioneer wireless system. The headphones are a bit bulky but they are very comfortable. The sound is amazing. It sounds so live- I sometimes have...
