Therefore I decided ultimately for the Sennheiser PX 200-II. Also if you do not consider him, he covers the whole ear opening on so that you is being protected well against ambient noise and is being protected especially the outside world before our own sounds. You can use it in a library with no problems! The ears remain free total, so you do not sweat too much.
For sound: The sound is really fantastic! You can hear nuances that are very balanced the ups and downs, there is no exaggerated bass as today, unfortunately, is the case with many headphones. The sound is clear, nuanced and multifaceted. In the price range you will find nothing better!
For seat: The strap is made of durable and elastic stainless steel, according to internal soft lining abfedernd. It does not express, you forget temporarily that you ever aufhat headphones.
Go to Product: The really practical at the PX 200-II is the collapsibility. You can fold it to a very small size and fast with a handle and then keep in a (supplied) small synthetic bag. Which may seem somewhat noble, but that's the only complaint about the product.
For appearance: The PX 200-II is really chic! Black, silver, minimalistic, no frills. Falls on Duch unobtrusiveness!
Overall, strong buy recommendation!
