The design and haptics are, in my opinion, very valuable. Beautiful faux leather and metal surfaces (?); for the price really good.
Comfort I find very good, the headset is easy and presses (me) not on the ears. Since I have worn it only a short time, I can not tell you how he feels after several hours on the head.
I have the headphones fired with a burn-in program about 30 hours, so that he einspielt itself. This is a common procedure to help speakers or headphones at a reasonable sound. Sometimes the differences are great, sometimes not at all audible - depends on the headphones / speakers.
Before the burn-in of the frequency response of the bass was clearly bent, just fat, a fat fold in the middle and ugly sounding highs. I wanted the listener already pack directly, but I thought to myself "Gibste him 'ne chance!".
The sound is, even after burn-in, still absolutely wrong. I did not even expect much for the price, but that bit was even undercut. The statement from Sony (Quote: "Look forward to headphones that can keep up with sophisticated hi-fi recording.") On the website is a brazen impudence.
Bass: on present, drowned out everything, very booming (no matter what kind of music); , this would have nothing to do with HiFi
Middle: significant elevation between (estimated) 3 to 5 kHz, sound corrections in this area by EQ impossible; again drowned out by the bass; Burn in has brought hardly anything
Height: Joah, there's was.Sprötzeln at the highest altitudes - that's it.
For all the love to the super haptics, but with the sound I can make friends not at all, and ever garnicht equalize with various EQs. Therefore, the headphones went back.
I have several other headphones listening test (Sennheiser, AKG, Beyerdynamic, Audio Technica), and each of these headphones has no straight frequency response; I'm aware! But as serious as the Sony was none of the other.
Bin then to the local high-end dealer I trust, and have had success there! Ultrasone HFI-15G for 80! Also, the headphones sound has weaknesses (is halt so in this price range to 100!), But with this handset, I can make friends much better.
For ZX600B: Theorem X, which was probably nothing!
