Sennheiser RS 170
The headphones could convince me in any form and can not agree with the many good recessions.
The headset has a relatively sound boards, which brings no real ups and downs, although you can optionally functions,
Dynamic Bass and Surround Sound switch, the tone will be a little richer, but a real bass is also not generated and surround is nothing to feel, which is probably because of the fact that the audio input only a stereo signal (chinch) can be used. The sound will total just floored and disappointed for headphones in this price range.
Even the comfort did not convince me, and this is of course subjective and depends strongly on us by the head shape.
The operation as a whole is somewhat tricky, especially when spoken and quietly ask one often gets off switch, as it all is key.
Sennheiser RS 180
The headphones are of the fit and the operation is basically the same as the RS170, also here you have the problem with the fiddly operation of the volume control. Good solution is that you also can operate with batteries headphones for emergency times, so you can sometimes pass the time for charging the batteries.
Unlike the RS170 has give the RS180 velor ear pads that are a little more comfortable to wear, but also a lot of sound to the outside, but only annoying is when you are not alone and must listen to all other forced.
From the sound of her RS180 to worlds better than the RS170, for pure music enjoyment, it is the first choice for the wireless headphones, he brings clean highs and the lows (bass) are clear. The headset features an automatic modulation which prevents oversteer and you can even adjust the balance, which is a great thing since this can not be more to the modern stereo and AV receivers.
For cineastes but also these headphones is rather unsuitable, unfortunately he has only a stereo input (RCA), which, although you get a quite passable sound, but not "surround sound".
Sony MDRDS6500
The Sony headphones inspired me from the very beginning, visually it looks very high quality, as well as the dock by the piano lacquer, also inserting the headphones into the charging station is consistent, he adapts to the station and the top ends with the charging station from.
Also was the comfort, for me at least, significantly better than in the two Sennheiser models, it is very comfortable, the ears are fully enclosed without which it expresses somewhere and even after several hours I had neither hot ears, headaches, by the way I am 1.85m and had hat size 60th
The sound is in Dolby or DTS movies in just fantastic, I am indeed of the opinion that even here, in comparison to my home system with AV receiver, not a 100% Surround sound is generated, but it's pretty damn close.
The headset produces a correct surround sound with rich bass and clear language, one partly noted. Not that you only have a headset on. The volume control is simple and straightforward with a brightness regulator adjustable.
The docking station has its own sound processor and you can select different modes.
Unlike Sennheiser you can at Sony except 2 Chinchkabeln also an optical cable (supplied), which explains why the Sony headphones can deliver the only proper surround sound.
I could see live concerts with no real disadvantage compared to the Sennheiser equipment even in music DVDs, depending on the type of music and personal preferences but you should try doing the modes of your processor.
Only in the case of pure music that comes from a CD, the Sony a disadvantage compared to the RS180, but that's about the only thing I did not like.
Therefore, I can wholeheartedly recommend the Sony MDRDS for sale, just for film buffs there is the case of radio headphones in this price range is nothing better !!
