WESTONE UM PRO 10 BLUEWestone
On tracks with intense sub-bass content, like The Knife's "Silent Shout," the UM Pro 10 suffers from a bit of distortion at absolute top volumes. At less intense, but still loud volume levels, the UM Pro 10 settles down and delivers a refined low frequency response. There's enough sub-bass definition there, so you hear the power of The Knife's electronic kick drum beat, but the rest of the frequency range gets more attention than the sub-bass realm. So, we have a crisp sound, with a healthy presence in the lows, but nothing approaching what today's bass-heavy earphones often conjure.
