I needed some compact and easily portable wireless headphones for work. Since I had, or still have, but waiting for repair, headphones SONY MDX XB950, so I again reached for headphones of this series from this manufacturer. It was already clear to me that these earbuds would not, during bass, "walk" back and forth on my head, as it was with the 950, however, I counted on the sound being tuned according to the XB series. I let the headphones "burn in" for about 3h, when they played without being in my ears, so as not to evaluate completely unplayed headphones. After I figured out the size of the plugs I could finally move on to the music.
Unfortunately, here came quite a disappointment. Bass is present in adequate amounts for earbuds, but what I really didn't like was the overdriven highs. So much so that some genres were unlistenable. Which leads me to my next problem: It seems to me that every genre has a completely different sound, which I don't understand how that's possible. With the XB950, the sound characteristics were more or less the same across musical genres. Here, the sound is OK for electro, but for rock or metal it was disappointing - flat sound with screaming highs. Also, don't expect to hear everything you're supposed to hear. As soon as multiple instruments come on stage, the headphones bring them together. For example, the sound of the drums was "interesting": the pedal was fine, the rest of the drums were very strange and the cymbals almost made my teeth fall out. Electric guitars are a shame to describe.
It should also be noted that even though I have big ears, these headphones started to hurt my ears after 4h.
Well, for the successful completion of this review, I would like to point out that after a week the sound started to "hiccup" quite often (about 0.5s long sound dropout) after which there was an indescribable disgust of the sound, which in about 1s leveled off again.
Bottom line, tried, returned.
