Some companies treat small reviewers like myself not too nicely, to be frank. Everyone should treat my reviews of AFUL IEMs with some reservations since (1) my ears pretty much align with their tuning style, (2) I pretty much supportive of how they approach technical aspects of IEMs and (3) whilst I have never talked to AFUL directly, their rep via Hifigo is friendly, respectful, and never push for positive reviews, so I like them. It does not mean I will lie to get AFUL and Hifigo more sales, but I do have a positive regard about both.
For transparency, small channels like mine would not have “sample” of something as expensive as Cantor and up. I did pay for my unit, though Hifigo immediately intervene and gave a good discount. The lack of reach and my way of ranking IEMs do get me cut off from certain sources of products, but it’s okay. No hard feeling.
When I said I’m getting more AFUL IEMs, I do mean it as there are still gaps in my collection I want to fill in, and AFUL tends to deliver. Say, I need a technical IEM like U12t, I found that in Cantor. Now I want something with good “vibe” like P7 but with good technical performance. Finger crossed the quadbrid would deliver that.
Btw, I checked with YouTube policy. All reviews here, as soon as a free sample or discount involves, is legally a sponsored / product placement / ads

All of it.
I’m still bracing myself for an inevitably bad release from AFUL. Hopefully it would be the planar rather than the quadbrid

I will review everything carefully and let you know.
