The processing of the headphone itself acts notch. First striking but is the purist design. Almost radiates the Sennheiser made a kind of retro chic. One is reminded of the devices, which were worn by the telephone operators of the early twentieth century. But even at second glance one falls for the rough charm of the part: Matter stainless steel shine at the temples, solid plastic to the earpieces (which are additionally protected by two foam plugs), the economical attached - but sufficient - padding the headboard, leather , with clean and firm set seams ... pride of ownership is spreading in one, if you hold it for the first time in his hands. What is still to come: The device is light and rather slim Seeming despite the extensive use of natural materials, which adds to its the fact that the ear cups the ear should not enclose but rest.
So this is the Sennheiser is a supra-aural system that still is closed because the device has an active (electronic) has noise cancellation, which ensures that you almost nothing heard from the area of interfering tones, even at a moderate level. It sets the phone down, turned on the music - and disappears into a different world.
I myself have the sound quality zunächt with a recording of the Goldberg Variations, played by Glenn Gould in 1955, tried. What a listening experience, you can only say; You could hear every little scratch, every tiny speck of dust in the sound groove. Clearly and unambiguously and the squeaking of the pedals or the muffled striking the keys of the piano - quite apart from the music itself.
In the song "Chestnut Mare" by the Byrds then the Sennheiser was able to prove that he again is also a bass faithfully. Again, in a very different kind of piece of music, to sound spaces, in which you could walk into the sounds opened, all of its well-defined place. Here no sound was washed out, nothing is ingested, on the other hand the sound space of the play but was not tinny dissected and broken down into its components. Even with stereo pieces of Sennheiser are one what his good name promises.
For Bluetooth connection, which is of course just a peculiarity of this headphone can say the following: the establishment is entirely easy. You press the Anschaltknopf right ear part for a few seconds while holding the device to the Bluetooth-enabled basis, ie on the laptop or Smartphon. Nice feature: power up sequence and Bluetooth pairing will be accompanied by a female voice in the handset, so you have to rely not only on the small little light on the side of the right ear. In addition to the on and off switch is also located on the right side of Lutstärkeregler and is easily found with his hands, even if you have the headphones on straight.
With regard to the distribution and size of the switching elements, so you can speak of a coherent design, particularly as it adapts to stresses minimalist line of the device.
The bottom line: The unit was decidedly konzipert as wireless high-end products primarily for the enjoyment of stereo music. And here the Sennheiser makes everything one can expect from his still slightly higher price. Who can afford it and love is willing to lie down one way or another hundreds more for the "finishing touches" on the sound quality, is well served determined with this device.
