Now for the price, the Edifier H850 is possibly best in class, most headphones around this range have boosted bass, or non-existent highs, these do not. These actually have good balance across the board.
The Dunu DK-3001 is a very well done hybrid IEM, the bass is dynamic and punchy, with excellent and realistic body. The midrange is well layered and very detailed, with and hint of smoothness to it. The highs are always present, yet not fatiguing.
The Dita Dream are a fun sounding IEM where everything is on a level playing field, nothing sticks out and nothing is missing. They are incredibly detailed, yet not analytical, however they do allow great insight into the recording should you want to analyse it.
