Got my pair of V7's about a week ago. Paid 74 euros per speaker as they were b-stock. In a small room they do really sound excellent for the price, when you get positioning just right. I can only compare to old B&W DM110i's and AKG 712Pro headphones directly though.
Compared to the B&W there is no comparison. These Swisssonics are fullrange speakers where as those B&W's are mostly ear piercing treble. Still highs have way better detail on the cheeses. Lower frequencies really suprised me and in a 4mx5mx2,3m room there really is no need for subwoofer when listening to music casually. Movies would benefit but these do suprisingly good job. If phone microphone measurements are anything to go by, they go to down to ~35hz before dropping off. But overall they are pleasing to listen even at higher volumes. Detail is decently close to AKG 712's when you get positioning just right, but still a clear (hehe) win for the headphones.
My pair does hiss quite a bit, but these were b-stock so who knows if that was the reason they were returned. I can hear the hiss even outside of the room through the door opening. So atleast ~6m of hisssssss, although this is basicly at complete silence(140mm PC fans at 450rpm are louder for context), and the hiss is not terribly annoying pitch. Can't hear any hiss when playing at low volumes, so personally it is fine.
Build quality is decent and nothing wrong in that department. I guess we will see in couple of years how durable these are, but if they don't release the powering blue smoke anytime soon they are amazing performance for the money.
The status indicator LEDs are pretty damn bright and obviously blue when on ON. So make of that what you will. Wake up time is around a second and in 15 mins of non acticity they will go to sleep with big red light to show it.
Would be intresting to see if these are actually any good compared to the A series
