If I have to choose one word to describe the sound of the Shape 50s its will be the word warm. I can listen this monitors hours with no fatigue. They work very well, even with low volume. I already made 5 mixes and all they translate well. The noise level is very low, almost identical to Yamaha HS50. Some people complain about auto standby, but it doesn't bother me. if you are in small room i strongly recommend using the monitors with the Low Shelf filter to -4db.
Pros
-They look very cool with the flax woofer and front wood finish
-The sound is natural and warm
-The mixes translate well
Cons
-A bit pricey
-The auto standby switch its located inside of the monitors.
