I bought these headphones when they were just on the market.
I ordered this by chance because there were no reviews yet.
I certainly don't regret this! What a beautiful headset!
Before this I had a Sony mdr-ds6500. The Sony is finished talking when the RS175 comes into play.
First I tested it with different music genres. The bass is phenomenal without distorting.
The surround is of course not like a real 7.1 speaker setup. However, this is played truthfully.
The wearing comfort is optimal. The shells rotate well with the shape of your head.
The RS175 uses regular AAA batteries. If you run out of juice during the film, you can replace it effortlessly.
The headphones moderately cut off the outside noise.
The headphones are not cheap, but they are well worth it!
Sennheiser is known for German reliability!
