Yes. S-Logic is designed to give you a much broader soundstage in a closed headphone. It uses a driver that doesn't hit the ear canal directly, but that is slightly angled to use the ear's outer rim in order to add some depth. Depending on the headphone model it works very well. Ultrasone sells a lot of different headphones that target different audiences. For instance, the Edition models tend to be very design-oriented and typically get very mixed reviews in terms of sound quality (I can't confirm that from my own experience). Others are for the pro market and tend to sound much more balanced. I own the Signature Pro, which has the newer generation S-Logic Plus, and I'm extremely happy with it. The soundstage is as wide as that of great open-back headphones (e.g. Sennheiser HD650, which I also have), but you get the isolation and bass punch of closed headphones. I retired all my older headphones (HD650, Grado RS1, Shure SE-535) after getting the Signature Pro. Unfortunately, this model is not exactly cheap ($1300 list price) and quite ugly, but I've never heard better music reproduction.
