Well, I now have 4 cables. So I thought I would write about them.
From left to right, stock moondrop blessing 2 dusk cable (2-pin), dunu duw-02 (2-pin), dunu duw-03 (mmcx - stock cable with zen), dunu blanche (mmcx). And a bunch of the dunu interchangeable connectors in different colors with a BTR5 my primary listening device.
I am not going to comment on sound. If they sound different, it does not matter at all to me. My primary focus is which cables are more usable (Like most everything else I look for in audio enhancements). I have no opinion on the “cables make a difference” debate one way or another. I am not even a/b testing these.
Let me start with the moondrop standard cable (2-pin - free). If I did not obtain the others, I would have very few complaints about this. There are advantages to having the fixed and smaller connector on a thinner cable. It’s a bit more prone to kinking and maybe tangling (you can see it kinking a bit more in the picture), but the way I use cables, that is a problem on all of them. For a stock cable at the dusk price point, I honestly don’t have any complaints. It doesn’t have a chin choke thing? (what’s that called?) It’s not the best, but it’s not bad either. I bought the dunu duw-02 simply to get the connector system.
The duw-02 (2-pin $80 with 3.5 connector only) is the bar all cables should hit. There is basically nothing wrong with it. I mean, if someone could come up with a slightly smaller modular connecting system, sure, that would improve things. On the BTR5, that connector can be just slightly more annoying than the moondrop stock cable. But, what you get for that is very nice. I leave connectors with their devices and move the cable. So there is a 3.5mm in my apple dongle, 2.5 in my BTR5 and pentacon in the dap (if I have one). This is wonderful. I am tempted to buy another one in mmcx as backup/extra. One gripe, charging $20 per connector for the extras is just ridiculous. Just up the cost of the cable and include them all like you do on the duw-03 and blanch.
The duw-03 (mmcx - free with Zen & SA6 - $189 separately with all connectors). Again, if I didn’t have this one, I wouldn’t notice what was inferior about the duw-02. And that is largely build materials. Metal connectors and choker thing (really, I need a name for it). It does have one potential downside: It’s much thicker and stiffer. This may be a positive or a negative depending on how you use it. It’s very sturdy, which does make it a touch less flexible. Not really an issue for me, but it’s something that could make a cable at that cost not worth it.
The dunu blanche (mmcx - $329 separately with all connectors). This cable may be the perfect balance between duw-02 and duw-03. It’s a bit thinner, so if the thickness of the duw-03 is a thing for you, this is good. However, it costs the same as the dusk IEM, and that seems a bit pricey to me. Now, it should be noted, it is a pure silver litz type 1 cable. If that’s a thing you care about, there it is. Do I care? probably not. I think it is slightly more kink prone due to it’s thinner nature, and possibly more than the duw-02.
All of them had roughly similar (and low) amounts of telephonic noise from movement. All have that additional plastic molding around the ears that seems to alleviate that. All worked well.
I find the three dunu cables to be very attractive. While the duw-02 is less flashy and inherently more my style, the other two don’t go overboard for me. In the picture, the blanche looks very white, and it is, but it has far more depth and coloration than that picture really shows. In fact, it almost looks closer to what the duw-03 looks like in the picture (which has even more depth/texture/coloration in real life). Whatever color the moondrop cable is doesn’t really appeal to me.
It’s pretty clear to me that if I were to pick the highest value cable, it would be the dunu duw-02. Assuming you are willing to spend money on a cable, this is my standard goto. If it were mmcx I would probably give it a run on my Zen and see if there is any difference to the blanche.
Also, headphones.com provided the Dunu Blanche cable as a solution to a problem I was having with the included duw-03 connectors with the zen. It was not free, but it was not full price either. I am very happy with the service!
