I bought a pair of M6 Pro IEMs and, while I think they are well made and comfortable, the sound is problematic. It has good bass and mids but the highs are piercing and harsh. Even after hours of burn in I am still experiencing unpleasant highs. After switching tips back and forth from Comply tips to various silicone tips, I finally threw in the towel and bagged them. It's too bad, really: I thought they had real potential as IEMs for traveling but, Holy Shlomoley!, those shrieking high notes! The M6 Pro is not for me.
