Review on Experience Ultimate Freedom 🎧 with Sony WI XB400 Wireless Headphones by Riko Tateishi ᠌

Revainrating 4 out of 5

I expected mediocre quality, but the product was pleasantly surprised.

Considered to be a computer. They are quite content with it, it allows them to work for longer periods of time, and it lessens the ambient noise (passive noise isolation due to a snug fit). Sound? To be fair, this is a matter of opinion. The sounds do not interfere with one another in any way, and everything can be heard extremely clearly. The bass is present, it is more audible, and it does not interfere with the sounds in any significant way; rather, it merely makes them more pleasing. For those who are curious, a graph displaying an amplitude-frequency response can be found through a Google search. Lag: I read some reviews, and some of them say that the latency is "awful," as if the headphones were not designed for gaming. At the same time, I can say this: there are various wireless headphones in which the PPC delay is so noticeable that it is impossible to even watch the video, and in the same ones I tried to catch it - and I'll say that it is difficult to notice. However, there are also wireless headphones in which the PPC delay is not noticeable at all. It's possible that they won't function for super-fast games like Counter-Strike or other such competitions, where every microsecond counts for anything. On the other hand, sound is conveyed relatively quickly in all of the other uses, and any delays that may occur are completely imperceptible.

Pros
  • Extended shelf life of the battery. They are designed to fit snugly within the ear canals. sufficient to separate you from the ambient sounds. When I was working with a computer, I did not notice any lag in the process (more details in the comments). Minimal accoutrements for the sense of touch: the buttons are raised, and everything may be done by touching them.
Cons
  • The wires appear to be quite thin, and because of this, I am concerned that they will snap easily (although there are no problems). When you turn on the headphones, a female voice in English announces the charge level and then goes on to claim that the headphones are fatigued. While headphones can be magnetized to each other by clasping together, the pull-off force is weak and the headphones can be easily separated; nevertheless, I would like it to be stronger so that the headphones cannot be magnetized to each other.
