an excellent iem, practically everything he does very well or excellently, outstanding in tonality and timbre, with dynamism.
I have been using single-driver reference monitor IEMs for over 20 years (mostly Etymotic). After many hours of research, I chose the RSV as my first multi-driver. Perfectly tuned for my taste, and the improvements in timbre and staging are much greater than I expected. The big surprise for me has been the total lack of fatigue - You can listen to these all day. A great value and highly recommended.
One of my best iems for the money. Top item from MusicTeck for value.
