This model of intra is not without its minor flaws: an aesthetic "cheap" and a fair sound isolation "in the middle" for ITE (but still excellent compared to other types of headphones)
But apart from these small insignificant default for my taste, the rest is great for the price: top ergonomics, holds very well with the many tips provided. The single balanced sound of its kind in that price range, ideal for those who like me listen to everything from jazz to rock to classical, etc. very versatile neutral sound unlike any other intra this price range that are biased to low and forget the rest.
