I just wanted to echo
@Dramlin since this thread is pretty dead and these headphones deserve a shout out.
I've been through a large number of Ultrasones, I generally love the way they are tuned.
The
Signature Natural is one of their very best. It has a very clean but tight sound revealing a ton of detail in recordings. They are not bass light - they have a perfect level of bass that is very impactful but does not muddy up any of the beautiful crisp details these headphones provide in the mids and highs. I don't think they need any more or less bass then exactly how they are tuned. The imaging is stellar and the drivers reveal so much detail.
I had a Signature Master and sold it in favor of the Natural. I would put them pretty even with one another, both are great. The Master has some more bass but it clouds up some of the rest of the frequencies vs. these Natural. I preferred the Natural overall and again, would recommend to anyone looking for a do it all closed back. I would say the sound is in line with an improved 780. I really love the 780 and still think those are a great buy for a very fun sounding headphone so that is saying a lot for these.
Out of all the closed backs I have owned or heard, I think these are my favorite and the 780 is a "fun" alternative.
I think it's sad they don't get the recognition they deserve in this community.
Ultrasone just doesn't seem to do any advertising at all for their headphones so you just have to find them to reap the rewards.
