Nice build. The buds are lightweight and seemingly well built. I appreciate the variety of swappable tips and tuning filters. The default installed was way too heavy in the bass and drowned out the mids/treble. Swapping in the neutral filter helped, but the sound still sounds a little muddled. Maybe, these will improve with more than a couple hours of listening (or I am supremely spoiled by my HD600's).
