I have these and I have to say I am very impressed; especially for the price point here. I have other iem's costing much more but the Primo 8's punch out of their weight class. they are neutral and handle instrument and voice timbre very well with a good soundstage. I like these so much, I bought another pair! Fit and proper amplification are important but I've been using a Sony ZX2 with great results. Highly recommend unless you really want a bass heavy deal or a sharp v shape sound.
