First of all, I want to praise MusicTeck for amazing service and thank Andrew for quick and on-point responses. After just one week after the order I've got my IEM via international shipping. You are guys are amazing, and I'm not saying that to everyone! Will definitely purchase again at your store.
Now regarding the MEST MK2 - they delievered exactly what I was expecting from them. Clean, very detailed sound while keeping the fairly fun and engaing signature. I would say, however, this isn't the most versatile IEM in my collection, but if you listen to acoustic music, jazz, rock, classical - this is a no-brainer, especially for the 1k$ price point. If you're a bass-head or listen to electronic genres more, I don't think this would be your cup of tea.
