Less well finished and less comfortable than the previous model it replaces: RP HS45. Equivalent to the latter the audio point of view. The reduction in thickness is visible but of limited interest. The thread of 1,20m length (equal quoted 2, unlike the HS45 that offered 1.25m 1.60m left and right) is a little short for my taste. In practice, if there were replacement pads for HS45, that would be a better option to renew them.
