In general 3 STARS. * I´m happy with the seller´s logistics* BUT when I received the inears .. I noticed due to a internal sound, that there's a loose part inside of the left earbud. Fortunately this don´t affect the sound but still sometimes it clicks inside of my left ear, and is annoying. the Right one is OK.
Those IEMs are AMAZING! I was a bit worried that by having to drive 6 drivers the volume sensitivity was going to be a problem but somehow the components within the IEM are super sensitive and they sound way louder than any other headphones I own, plus clarity, soundstage, and overall audio quality is sublime!
