Just the looks alone justify a purchase in my opinion. Images don't do them justice.You really have to see them in person.
Regarding the sound... I will keep it simple. They have a very prominent mid bass punch that is quick and which is more than the B&W P9, Denon 9200 and Ultrasone edition 15 but from memory not as much as the Campfire Cascades. Sub-bass is slightly elevated but not like the 9200. Mids are slightly recessed and highs are a little elevated in the upper registers but not detailed as the 9200, P9 or Edition 15. So i get the feeling that this a warmer tilted signature. Pardon the pun but this punches above its price. The mid bass, portability and looks are the defining characteristics for me.
