Actually, im pretty content with my kz bt cable. Aside from that stupid gain problem (which takes 10 seconds to fix) it's working well, very high volume,good connectivity and good SQ.
Seems completely crazy they are letting TRN dominate the tws adapter market with the bt20s/pro, which has many unsatisfied users ATM.
Better battery life, better connection stability, LDAC support and a non-screwy tuning and I'd be on board.
I think it's hilarious that with the release of the ASX, the latest reviewer ends up looking fondly upon the AS16. Almost makes me want to give them a shot.
That's true. Sadly we do not have an option for a trial per se in the Philippines. As far as I know we do not have Azla's merch. So shotgun buying it is. Lol
Yes the sound is wider too. I am not sure if it is intentional, but both ways do sound good and not weird. OR maybe they messed up and wired it wrong in the production line lol.
I tested the polarity and phase of my ASF with the cable it came with and everything seems a-ok.
There are some youtube videos with test sounds.
Now back to the music!
Yes and no, KZ uses a reversed polarity QDC as it's connection. So the cable and wiring inside the IEM have the + and - flipped compared to any other IEM using QDC. This has been measured by someone on this forum but can't find the post atm. This can in certain circumstances lead to issues, luckily not like the ESC's on my rc cars. Yes it'll do 120A continuous and 760A burst but if you flip the + and - on a 5.8A battery it will go up in smoke instantly. Had this happen multiple times when preparing a car for a race under stress

So I think QDC usually has a reversed polarity compared to a non-QDC 2-pin connection, but you are saying KZ reverses the QDC polarity, so that would make it the same polarity as non-QDC. Is that correct?
So any generic 2-pin non-QDC cable should work fine?

Not sure as I don't have a ASF or ASX yet. Whether it works better with 2 pin or QDC is dependent on the crossover pcb I think. Some don't care, some are fussy.
Neither have I, that said I've only got two balanced Tripowin C8 cables that terminate in 2.5mm and 4.4mm respectively. So power is going to both + and -. And I only use them with the ZSX which if fine with just about any cable it seems.
I read something yesterday that made me think most of the QDC cables on AliExpress aren't actually the official QDC cables which have reversed polarity.
They have same shape and sleeve, but not reversed polarity.
Not sure if this is true or not, but it makes sense as it seems QDC reversed polarity IEM's are kind of rare, but QDC cables are numerous with budget cables on AliExpress.
All this "hobbyism" and "audiophilism" may enhance the market, but it really doesn't help sound quality to develop. I know, audiophiles tend to call people, who care about technical accuracy, audiophiles. But in reality, if you apply logic, audiophiles are the people who believe audio equipment is a piece of art itself, rather than a sound reproduction instrument. Thus, people who believe that earphones make music more "fun", "groovy", "exciting" or "musical" are the veriest audiophiles. Music, as it was created, not being alterd in some way by earphones, is "flat", "boring" and... "not musical" for such people!
Looking at reviewers and just regular users, you can see strange things. Neutrality is not considered a defining criterion of sound quality. Some people even talked themselves as far as considering it unwanted!!! Resolution is also something not absolutely necessary for high quality. Then there are people, who say some earphones have "too fast atack/decay". What? I mean, attack and decay could be slow, but can someone even explain, what are too fast attacks anyway? Like, they are faster than signal itself? And of course, short treble extension is also "good" for bad recordings. (We are talking about times when you can store hundreds of albums even in high resolution on a card in size of a nail!)
The accuracy in all possible aspects is not demanded and is not considered the absolutely necessary criterion of sound quality by too many people. You know what, guys? With those stereotypes there is no way of telling a good earphone from a bad one. Its all down to subjective opinions that way. I can call EDX the best earphone in the world, way better than any fancy things for thousands of bucks. This opinion would be as good as any other. There are $1000+ earphones that have bloated bass and treble peaks for pseudo-detail and still getting good reviews.
So what manufacturers, like KZ and other chi-fi, should do really? What aim they should pursue?

Sounds logical as KZ and CCA are probably the biggest users of the QDC style connector so it seems logical to make polarity the same as the standard KZ/CCA cable.
Talking about this QDC polarity vs 2 pin and the reversed polarities is making my head spin so quick summary (to the best of my knowledge);
True QDC = reversed 2 pin polarity
KZ/CCA QDC = 2 pin polarity
