Thanks to Amazon, I was able in September buy this helmet (new and guaranteed) in Germany at Eager to 159 shipping included !!! I have owned several headphones, wired and wireless, stereo or 5.1 (Sony, Phillips, Sennheiser). This is absolutely the best. Apart from a slightly shortened dynamic range (no ear fatigue), everything is there. Every detail is audible. The separation L / R is very good, also spacialisation. The medium is a bit emphasized, very pleasant on jazz or folk. Very good also classical, I found a less convincing hair on electronic music. Excellent for home theater (voice and bass very robust), untreated 5.1 is absolutely not annoying.
Never any parasite, despite several wifi networks nearby, I only had to plug for perfect sound at first. Listening is no problem in all parts of the housing.
Lightweight and very comfortable, I can support the several hours straight.
His only shortcoming, in my opinion, in the absence of digital input. I had to connect at the "pre-out" of my preamp (NAD home cinema). But it apparently does not allow all sources ... However, there are adapters.
In conclusion, the Sennheiser RS 180 headphones, is, in my opinion, the best Q / P / comfort / free market, all technologies. And besides, it's beautiful ...
