Review on Sony WI-C310 wireless headphones, blue by Micha wierczewski ᠌

More over two years have passed since I first started using these headphones. Never before have I owned headphones that were able to last for so long. They functioned correctly, and the battery was, of course, of the highest quality. However, after some use, it became obvious that the battery could keep less of a charge than before; this was not an emergency situation. They were actively used for more than two years, practically every day for four to seven hours of listening to music, and in principle, they were turned on for at least six hours every day and played music for at least two hours every day. And now, two years later, I am able to charge them every two days; in other words, they were sufficient for two days' worth of labor, despite the fact that on the evening of the second day, they reported that they would soon be discharged. This was possible because I had waited two years. My ears were comfortable with the form of the headphones, and even at 80% volume there was no outside noise that could be picked up. Even though they do not have active noise cancellation, the fact that they are earbuds means that their design alone is sufficient to block outside noise even when the music is playing. In general, I was satisfied with the headphones, and considering the price, I think they are rather good.
