Thanks for the review. A couple of comments. Having now used these for quite a lot of hours with a better cable and better tips (Spiral Dots), I think it is important to mention the much more open and 3 dimensional soundstage that that Blon 05 has. Blon had suggested the new Chamber shape would make a difference and they are telling the truth. It is just that much more 3d and a great improvement.The general warmth that the 03 bass brought to the table is mostly missing, but the 'cleaner', mids work well with most vocal music and timbre is still A+.. Like many IEMs, long listening periods are important to get used to the IEM...brain burn in, and then on to the empirical burn in.

Thanks for the Review
