Entry into the S-LOGIC

Natural Sounds, 01.04.2016
It all started with the first model for sound studios for 700 DM in a questionable prototype design (yellow plasik housing badly black painted) in a cart. With the thing I became old, but I could never perceive the "In Front Effect". The AKG K-290 Surround has fit better for me. Still a good overpriced working bull. Special feature was the stereo double plug at the end, whose meaning is still not clear to me today. Because the S-Logic effect is not perceptible to me, I have the simplest model as a fifth listener attached. In the price class the performance is in order and you can improve the wearing comfort with »Beyerdynamic DT-250 Ear Pads Softskin«. In addition, these are also cheaper than the pads of Ultrasone. When you first set up, the headphones crackle pretty. Also, the entire headphone is not decoupled. Any movement or touch will be heard! The plastic strap, which is also found on other brands and also used in higher priced models is probably a compromise to fold the headphone small. The cable is sufficiently thick and makes a good overall impression. On the Internet and also with Ultrasone itself, there was incorrect information regarding the cable. There stood 1m plus extension cable. 3m was delivered in one piece. The Thomann description was correct. There is no longer the basket. In their stead a thin plastic "gymnastic bag" has appeared, an annoying bad joke. Each linen bag is better, cheaper and air permeable. I have plastic bags which are better processed. So Ultrasone has not done a favor and I have disposed of it. The price of 4.95 euros is much too much for the unwanted and paid addition. At the baker I got a better processed cotton bag. From Ultrasone there is also a, with 30 euros too expensive to buy transport box. In fact, the headphone, like perhaps the »Superlux HD681«, forms the lowest edge of studio headphones. The sound is very material dependent. For some pieces of music, the listener sounded very »topfig« (S-Logic effect?). With film sound it was different and to use. The quality of the headphone amplifier must also be considered! When comparing with three different models I also had three different sound pictures! Tested with the headset and Audirvana Plus, Fidelia and Amarra players with these audio formats: CD-16BIT44kHz, Stereo Stereo Original Resolution, Stereo 24BIT192kHz, Stereo 24BIT352.8kHz, Stereo DFF-DSD-64-2.8224Mbits, DFF-DSD-256-5.6448Mbits, Stereo-DXD-24BIT352.8kHz, Stereo-FLAC-24BIT96kHz, Stereo-FLAC-24BIT192kHz, Surround 5.1-DSD-64-2.8224Mbits and Surround -5.1-FLAC 24BIT96kHz. Also good for testing the spatial image »Gravity«.

5 stars for the comfort because it closes very well and isolates well of the outside and in addition it is comfortable !! The leather earbuds look more solid than that of sony which quickly shreds.
The sound is very soft and very pleasant, that is what I searched for. Not very deep in the bottom by cons, from where my 4 stars.
I put 3 stars to the manufacture because it is only plastic and I wait to see how long it will last in time.
So overall for 88 euros it really is a very good product, better than the Audio technica in the same price range.
