More than one year ago i spent more than an hour to listen to the ed10, really wanted to give that headphone a chance,
i left the hifi shop with a hd 800, i would not have paid even 100 whatever currency for the ed10.
Last year i spent half an our at the high end munich to listen to ed8, sig pro an ed10. While ed8 and sig pro sounded ok but no wow effect the ed10 for me was as bad sounding as before.
I left the high end with a new t5p.
This year i listened to the ed12 at the high end munich and was even more dissapointed. Stopped listening after some minutes.
I went home with my new final audio piano forte viii.
May be next year i will listen to the new ed14 and go home with an agk k6006.
Usually when you listen to a new headphone, you get an initial impression about the sound, also with the ed8 or sig pro that was possible to get an impression of the general tonality, soundstage, bass .. but with the ed10 and now the ed12 the only impression for me was and is that this sound has nothing to do with sound and how the screw ( sorry for that word not written completely) can any manufacturer release such a product.
What i don't like is that ultrasone difference between theory and reality, sound description vs listening experience, unproven theories vs sonic result, and the neverending ultrasone headphones argument that the headphone is excellent but my unability to get used to their whatever logic plus prevents me from accepting that they sound excellent.
By the way, i love headphones and listening to music with hedphones starting nearly 30 years ago with stax sr lambda, srm-1 and nakamichi dragon with dual highcom ii, but have never heard something like the ed10 and ed12 in a bad way.
I really want want want an ultrasone ed whatever with the build of the ed10, the quality, the look, the materials, comfortable, light, ... but
If you call ultrasone for information, contact them via email etc, they are fast responding, friendly, helpfull, really nice guys.
But for me it is impossible to understand or hear why the ed10 or ed12 ever were released as a product .
