Just received Yincrow RW-3000 from aliexpress summer sale. Quite amazed, the most natural and balanced sounding earbuds in my collection, very smooth with nice visceral bass, unoffensive treble, and surprisingly spacious soundstage. They just sound big, like good full size headphones.
The others in my collection:
- ATH-CM700Ti - great details, elevated mids, not super bright, but almost complete absence of bass
- Smabat ST-10s Gold (150 Ohm) - more technical than ATH, almost perfect except that treble spike that depending on the source can be quite fatiguing, FiiO bass foamies tame it to more or less tolerable level.
Yincrow seems like the best tuned earbuds so far, almost ThieAudio Monarch MK2 neutral, in fact I think they are extremally close timbre wise.
Great build and packaging, supple, nice looking modular cable, leather case, comes with a bunch of different foamies, but I just went for FiiO balanced tips right out of the box.
EDIT: Thanks ARES 35, samandhi, baskingshark, and all other users from this thread for their recommendations and help navigating through the sea of earbuds offerings.
