The sound of this InEars is impressive in the price range. The whole thing is quite bass heavy (it can be seen as a negative point) and the bass is also quite busy and not sounds dull, just like in cheap headphones unfortunately often. But otherwise, it is now sound not necessarily perfect. If you want it even louder, can quickly come to the heights clink times. But as I said, for the price I do not expect the sound quality of a high-end headset for 3-digit amounts. The price-performance ratio is quite good and in my opinion better than eg the Sennheiser CX 300 II (about 38) which, although the sound of her is better, but not more than twice as well ...
