As one of the many fans of the CX200 / CX300 line of senkhs (I'm talking about those who have already demolished not the 2nd or 3rd such pair), I can say that these are the same ears, only in a wireless format. I'm terribly pleased. Of course, there is less bass, but this is apparently a consequence of the fact that the diameter of the speaker is also 2 times smaller than in 300x. But otherwise the same sound. I took it for sports and everyday life - that's it.
