The Pro equivalent of the excellent Sennheiser HD 560S
eric-65 14.12.2021
More sober look (than the HD 560S); 2 cables instead of 1 (including 1 of 1.8 m; the other is coiled and is 3 m).

Less resolute than a Stax SR-009 (which I have owned), but more neutral (better tone) and more pleasant to hear.
Excellent and sufficient resolution, although there is even better.
Spacious and pleasant soundstage .
Respect for the timbre of voices and instruments, among the best.

Points for improvement: clamping a little too hard for big heads;
A little coquetry in the treble at 4.5 KHz, quite punctual, sensitive mainly for the cymbals, a bit too present; the rest of the tone is "perfect"; good extensions in the sub-bass and the upper-treble.

My best headphones (with the Sennheiser HD 560S), ahead of headphones costing more than 10x more expensive, significantly less balanced for tone.
