Demoed this set. To describe it in one word I'd call it "fun".
This set from Moondrop won't set the world on fire like their variations and blessing 2 did, but it's not garbage either like some reviews have portrayed it to be.
With a warm tuning with an upper mid range boost, vocals and percussion instruments pop. I was particularly impressed with kick drums in rock tracks. However none of these were to the point where it was fatiguing, I'm sure I could listen to this for hours on end. Midrange was transparent, instruments and vocalists there didn't feel dry or thin. Treble presentation was controlled, no sibilance with female j-pop vocals. Overall it's well tuned for what it is with no offensive timbral issues.
The set struggled in tracks with lots of layered sounds. Staging wise it's intimate, horizontal and accurate enough.
The fit was not good on my head at all, would be suitable for those with narrower heads, On my head the clamping force focused above the temple and was uncomfortably noticeable at the end of 30 mins of listening. Also it weighs next to nothing so if it fits it wont fatigue your neck.
The build won't impress anybody but it doesn't feel like it would fall apart either. It should be able to cop some abuse but without long term impressions we can't be certain.
It was ran to appropriate volume by a dongle DAC. I imagine it would be fine of a smartphone or PC output.
