Superb fidelity and response. Best in class at a reasonable price.
Best in class dynamic IEMs. Of all the dynamics I've ever owned these are the best, even at high volume. I own and have owned a lot of headphones and IEMs ( I mean a LOT!). And these are the best at this price point or any other. I own quite a few of these Sennheiser IEMs including the very respectable IE 100 PRO. But over their whole range I think the 600 hits the sweet spot as to response, linearity, distortion, build quality and fitment for this price. You won't find better. Personally I prefer BA IEMs and use many different models. But when it comes to pro quality dynamics these are my favorite.
