Here is the unboxing for the Dunu Alpha 3. I actually really like this set. I can see it doing well with flatheaders but not sure how much of an impact it will make in the mainstream market. Overall great package and sound. Dunu did a great job.
It's been frustrating reading about all the praise for the Yinmans as I agree that they sound wonderful, when working. I've even thought about trying another pair but am decidedly leary.
I wonder if any others have had QC issues with them?
I've had the Yinman 600 ohm for almost 6 months, using it every week in my rotation and so far haven't had any QC issues (touch wood).
I'm sorry to hear about yours and @prakasitp 's issues, seems like an unlucky CHIFI luck of the draw thing. Would u be able to send it back to the seller for repairs or perhaps ask one of our helpful forum members here to see if it is repairable?
Undortunately, once i hook up with Mojo2 then I experience the crack sound when it goes to heavy bass and high pitch music note. Only on left side though
.
Does anyone experience this issue? or anyway to solve it?
I haven't posted here in a while as I got really frustrated with my set of Yinman 600s not working and just bailed on the thread for several months. I've had problems with other earbuds also which contributed to the frustration but the fact that the Yinmans were significantly more expensive upped the annoyance factor.
I bought my pair from the same store and they went bad on me after owning - but not using them much - for a few (maybe several) months. In my case it was the face of the right earbud loosening up from the rear and the channel cutting out. Then a while later the right channel came back on and the left one cut out. Unfortunately I didn't consider that the seller would do anything about it (at least without my shipping them back which I didn't think would be worthwhile) and just tuned out.
A few members here offered to try to fix them for me and I'd like to thank them now, which I neglected to do previously. I figured I'd try to get a tech to look at them locally, to not burden anyone if I didn't have to. I haven't yet done so but will shortly as I have a major piece of equipment that also has to be repaired.

Gosh, that is sad to hear. Unfortunately, and very sad to say, we all must accept a level of risk when purchasing anything from China. It is a real bummer at any cost... whether ~US$150 for the Yinman 600 in your case or the ~US$600 Ks Bell-Ti that royally failed in my case .
Since 2016 when Yinman (Longyao-Yinman) launched these have been the only two (2) serious QC cases reported that I know of thus far... plus one (1) case of the wrong impedance model version being sent to a customer (don't know if it was a nefarious "bait n' switch" event or a genuine accidental mix-up at the store and/or maker-brand level).
That all said, we will need to carefully monitor this and see if any more such QC issues and/or mix-ups occur especially when the new model lines launch (metal shelled 150Ω coming any day now and the reminder of the series in August/September timeframe).
I've been trying out so many buds in the last 6 months it's been kinda crazy. There's a few standouts though. My current obsessions are TGX Ear Sunniva and Rikubuds Alter Rider 3 (releasing soon). If looking at lower prices I like Rikubuds Lancer 1, Nice HCK EB2S Pro and Yincrow X6. I have a video where I went over most of the buds I've tried this year as well
Great video and worthy insight on flatheads. There's so much variety out there and quality is so variable it's hard to know where to start. From the sets on your list that I've heard, I largely agree with their placement. I'm also glad to see the love of my life, APWS, up there near the top.
