Great Headphone, with also mod, go on next level.
Another little pearl, from ESS.
I summarize quickly, the excursus on this headset.
As soon as I took it out of the box, and also listened to during the burn-in, something didn't convince me.
The 2 drivers, dynamic 40mm and the driver from Hell, were fighting over some crossover frequencies.
Phased the driver of Hell, by inverting its polarities, for the phase shift of 180 ° introduced by the filter capacitor, things have settled down.
The 2 drivers "speak" in unison, and they do it well.
Further steps that made me change my opinion on the little ESS, to the point of defining it as a small pearl, a unique object of its kind, were:
1) the introduction of make-up removal pads inside the pavilions
2) the change of the original pads, quite horrible both in terms of comfort and acoustics, with angled oval hybrid pads.
made this way, this ESS can be listened to for many hours, comfortably, and above all with a realism of the instruments up to now the prerogative of the magnetoplanars.
As I said, this is asap mod, take these impressions of mine as such, and especially after making the recommended changes.
Would recommend to a friend.
