After the first hearing with the new Sony headphones my impression is mixed. The processing is highly satisfactory and at the price! They sit without pressing, close well and allow any volume of outside of the ears. Particularly outstanding is the processing of the cable. It is thicker than conventional sheathed headphone cord and the plug is bent and has a longer stalk, so you have to have absolutely no worry, someday to have a loose connection or cable break in the connector. And it also looks chic pending.
The sound, however, is rather poor. It lacks the ups and downs and everything is quite Bass watered and not as clear as with more qualitative headphones. Especially classical is not sonderlicher enjoyment. If we use an iPod, you can with the Equaliziern ("Less Bass" for example) to control something.
My conclusion: For the way perfect headphones because they are inexpensive, fit for purpose and built exactly in the right places robust. At constant packing and unpacking the way you will keep a long time. However, anyone who wants to use at home in peace headphones and much emphasis on good sound, definitely should dig deeper into their pockets. Go but really good.
