The C6 model by gorsun offers a well-balanced, almost flat audio experience. Many people might dismiss it without looking twice, but in all sincerity, with a decent audio source, these earphones' level of clarity in the mids and highs is extraordinary. The bass, however, could be better both in depth and stability.
If you appreciate a neutral, smooth and peak-free sound and don't listen to bass-heavy tracks, you will be surprised how lovely these earphones sound for their price.
Excellent flat sound signature with no noticable peaks at all.
Very decent build quality for such cheap earphones.
The over loudness isn't that great.
Could use some extra warmth and sub-bass.
A flat cable is always a bad idea. They are usually less durable than normal cables.
The inline remote is placed way lower than it should be.

Comfort & Fit
I had some issues keeping these earphones inside with a good seal for an extended time with the included tips because the profile of these earphones is quite short. I had to use tips from other earphones instead, and I advice you to do so as well. Maybe some nice foam tips can do a better job.
Lows / Bass
The lows are somewhat present, but are unimpressive and not the most stable I've heard. They are moderate with a flat mid-bass and absolutely no sub-bass. Enough for warming up the mids but not enough for bass-heavy tracks. Stability-wise, they are not the cleanest either, but if you're going to listen to tracks that don't require mindblowing bass performance, these will be more than enough.
Mids / Vocals
The mids are quite smooth, unexpectedly clear for such cheap earphones. They are not recessed at all, and are pretty well balanced with the lows and the highs. Tonally they sound about right, not dark and not that bright, just... neutral.
Highs / Treble
I found nothing negative to say about the highs, really. Level of detail is actually very impressive for such a dirt-cheap price, there's way more shine than I could have ever expected. No sibilance, no harshness. Just pleasant.
