Review on Headphone player Sony NW-WS413 by Agata Gajda ᠌

The first headphones worked for 3 years, in the mode 3 times a week in the pool for 1 hour. Then the red light came on and it stopped charging. The service center said that they are not repairable. It's a pity of course, but the result, in principle, suited me. Bought a second headphone. These worked for 1 year and 3 months and started to fail while sailing. And then they turned off completely. I think for 7 thousand they could have worked longer. Still SONY. I will try to look for a pool, something else. But something doesn't work. Maybe someone will advise?
