  What do you guys think, do those 7 driver IEMs have crossovers etc, or will it be another QT5 with just a bunch of drivers crammed in?

After my experience with the z2016 I'll let others be the guinea pig.

 
Agreed!  That's the way to fly!

Today I got my budget price TY Hi-Z HP-32 earbuds. The first buds that have good bass without eq.
 
Piano sounds realistic but no "air" in the treble which is a bit weak, needs some eq. But this is fresh out of the box mind ...
 
Burning them in now, but already I can tell they are waaayyy better than the in-ears I got with my hi-end Nokia phone. The Nokia N8
has just enough power to drive the 32 Ohm buds to a volume I wouldn't want to increase any further.
 
Bottom line: great value for the ridiculous price of 4 US$ plus 3 $ shipping. Plus they came with 4 sets of foam covers instead of
the advertised 2 sets. So I got some cheap replacement covers for my old hi-end Sony bio-cellulose buds.
 
After the burn-in I'll compare the Hi-Zs with my Sony MDR E-888 but the Sonys definitely need some bass boost which the TYs don't. If I set my phone eq to +3 or 4 @53 Hz I get a nice strong dry deep bass, too. So even medium bassheads could enjoy the TYs I guess ...
 
If you look for dirt cheap, don't look any further LOL.

The electronic product sheet from Zorloo themselves lists 4 ohms, did they update that value elsewhere? I was looking but I didn't find the 4.7 ohm number anywhere else. TIA

Really? In my product sheet, there is no mention on output impedance, and I can't find any information about it on their website either. Granted, the 4.7 ohm is second hand information, people quoting the answer they have received from Zorloo when they've asked.
 
Actually, @HiFiChris calculated the output impedance in his review. I have never measured it myself, but to quote his review: "With this, the output impedance can be calculated and what I get for the ZuperDAC is a little below 7 Ohms – for in-ears that have a capricious impedance response (about all multi-driver in-ears), this is obviously somewhat too much."
 
Anyway, I don't have any first hand solid proof, so I'm not going to stick too firmly to the 4.7 ohm statement..
 
Would be interesting if you are able to measure the output impedance of yours. Might have mentioned this already (I'm too lazy to check), but I'm having some 16 ohm IEMs on the way that I hope will pair well despite this.. If I would have bought the IEMs before the DAC, I would have probably looked into other alternatives because of this.. Oh well, so far it sounds brilliant with everything I've tried it with.

Based on my feedback, no additional resistors (or at least fewer, not 100% sure myself) are used in the signal path anymore, so the newer batches should indeed have a lower output impedance than the sample I got to try. If I recall correctly, something around 4 Ohms should be the OI of the newer units.

Thanks, both for the answer and for managing to get them to lower the OI on the final product. Still wish it would have been even lower, but there might be technical difficulties in achieving that, I suppose.

 

[HiFiChris]

The ~ 7 Ohms were due to a short protection circuit recommended by ESS's spec sheet that Zorloo then implemented. I pointed out that there are other applications with the same chip but without the additional short protection. Based on this feedback, the ZuperDAC was redesigned, went through stress testing and has got a lower output impedance since then.

Might be a lot to ask, but if you have any contacts at Zorloo, could you ask them what the OI on the release version is? Or maybe ask them to send you one for measurements..?

 I asked Zorloo for a full spec sheet and they emailed me a PDF with the relevant information, and it was there it was listed at 4 ohms. I emailed them to clarify it.

I am not even sure how I would go about measuring the output impedance as I don't have the tools for it I would imagine. Perhaps you can point me in the right direction. Is your incoming iem an all BA or hybrid iem?

  How can You tell? Only by looks? There are many drivers that look exactly same. Might be just a selling trick again.

  Yes, but as far as I remember there were fakes also.

 
 
The ones on Ali that these guys are buying are real. The fakes don't have the rotating nozzles.

Nice! Thanks! The lower the better, as far as I'm concerned
 
I've never done it myself, but maybe someone like @HiFiChris can give you some tips? I was going to give it a shot, but then my multimeter broke, so I never got around to actually doing it.. Given the tools I have(/had), I'm not sure how exact I would've been able to measure it, but I was sort of thinking about starting out with trying to measure something where I already knew the OI and see how close I got.. Anyway, I will have to get a new multimeter eventually, I might give it a try when I do.
 
When I was looking into information about methods I stumbled across threads like http://www.head-fi.org/t/739322/how-do-you-measure-a-headphone-amplifiers-output-impedance
 
It's a hybrid, 1DD+2BA.

If you look for dirt cheap, don't look any further LOL.

I'm so curious to hear my pair, ordered some days ago... So still some time waiting...

I quite like the look of these and that leather carry case is really nice. 1DD+1BA? Hard to tell from the specs.

Simgot has a chinese web site. It's a single DD.
 
I was going to sample it, but I put a lot of that on hold for now as my confidence (and credibility) was shaken a bit in reviewing with the QT5. Brooko's FP post is pretty spot on with how I'm feeling.
 
In time I'll be right back at it, looking for more diamonds in the rough.

DD good for produce good Bass
BA better for clarity of details, such as mids or treble.

Single DD usually can't last you more than a 6 mths IMO.

Multi-BAs good but not exactly for fun

Edit :
Single DD sounds to me won't last longer
