I use it since January 2008.
Same opinion as arouzy ( https://fr.audiofanzine.com/membres/a.play,u.375275.html ) . It's very good.
I simply add that this headphone has 124dB sensitivity. Thus, a sound you consédèrerait "low" with headphones lambda is significantly amplified for the same thing ... breath ... which can be annoying ... it important to have a clean source and carefully select its HF system.
The investment result was: 923 € in my case (the headset (890 €) + shipping (13 €) + borrow (20 €)), but I wanted to direct a high-end headphones, rather than putting € 400 in a headphone molded base and make a new investment later to ultimately buy the top model ... and lose the 400 € first headphone ...
I hesitated with EM2pro, but saw the reviews for 150 € and more, I took the leap ...
Today I am very pleased with these headphones: the finish bouhaha auditoriums poorly equipped than the single acoustic drums, the amps too hard and finished colleagues struggling to hear what I play!
