Since I can not afford a 5.1 surround system by roommates in the house, of course, needed a Kofhörer!
My first was a set of headphones that I had bought at ALDI, I did away after a few weeks quickly because flabby bass and no Surround button or option again. After that I bought the Sennheiser RS 130 with which I was basically satisfied I kept this a while. Then after a while I wanted more bass power, wherefore I me now to Sennheiser RS 170 ordered. Now that I am a movie fan, I wanted to have the sound close to the theater sound. The RS 170 has with activated bass button and surround button almost a perfect cinema sound. The volume can be far enough turn the RS 170 in the Height (Which in turn was a criticism of the RS 130).
Conclusion: If his films / DVD / Blu-rays as close as possible you want to experience the theater sound, and can afford, for various reasons no surround system, is operated with this headset great!
No noise, Super Bass, Class surround! Tip !!!
