The Yinyoo IN8 (also sold as Aigo A680 in China), is a nice pair when it comes to bass. Their mids, however, are not what I would expect from hybrid earphones, and their highs are rather disappointing and unnatural. For these earphones' price, I expected some higher level of audio transparancy and definition, but what I got was more like a louder and upfront version of YINJW P8.

Comfort & Fit
The IN8 come with the cheapest, most generic translucent white ear tips that is possible to get. The pre-applied M sized tips are so thin and soft that I found them to be quite useless when it comes to getting a seal. The L size tips are narrow-bore, but they did the job. Overall, the earphones are light but quite long, which means they stick out a lot and there's nothing besides the tips that's keeping them inside your ears.
Lows / Bass
The bass sound quite nice and warm. The lows are mainly focused on the mid-bass, rather than the sub-bass, which inflates the sound a bit. The bass does sound impactful, but there's barely any sub-bass to speak of. Eveything is driven by the mid-bass.
Mids / Vocals
The mids sound a bit recessed and constipated, with some bump in the upper-mids/lower-highs which creates a weird disbalance between the mids and the treble, to the point of being overwhelmed both by the bass and the lower to mid-highs. With all that, not much impressive detail to be expected as a result of lackluster discolored treble. The positioning of vocals sound weird to me, sounds too close and in a weird direction. Soundstage feels super condensed.
Highs / Treble
The weirdness of IN8 begins in the treble. The upper-mids and lower-highs are very emphasized and even somewhat harsh, but not in a fatiguing way. The timbre is just not right - it's overly dark. The best subject for comparison is Tennmak Pro. While Tennmak Pro keeps a balanced and natural experience of mids and treble, the IN8 just doesn't have that shine and sparkle in its treble and the detail isn't that impressive.
