DUNU’s a Chi-Fi company that’s been in business for more than twenty years – that’s longer than I’ve been alive! Of course, the star of the show today is the Luna. This is their flagship DD IEM that uses a beryllium driver. In theory, this is the ideal driver material in that it’s extremely static. As for how that translates to practice…well, you’ll see. Or rather you’ll read. The other two IEMs I was sent, the DK-2001 and DK-3001 Pro, are more standard hybrids. I don’t think I’ve done a “lineup” review before, so to keep things simple, I’m going to group the tangible stuff together and then analyze each of their respective sound signatures separately. There’s definitely some interesting stuff going on with this lineup, and if anything else, I’m glad to see that DUNU’s keeping things exciting.
In the interest of full disclosure, I want to thank Tom of Dunu for sending these along to me for review. At the end of the review period, they’ll be returned of course.
I was sent the IEMs themselves as well as a few accessories. So no fancy packaging. Maybe when I make it big, I’ll get sent all that stuff! Just kidding. I don’t fancy paying the return shipping costs. Here are some brief comments on the build and whatnot:
- Great cable quality and pouches for the IEMs. DUNU clearly cares and is putting in a good deal effort here.
- All of the IEMs are quite small. This is definitely a plus for smaller ears. However, if you have larger ears, it might feel like the IEMs are a bit loose (although I doubt they’ll actually fall out). None of them isolate particularly well.
The Luna’s build is noteworthy to me because DUNU’s using titanium. This is the metal of the gods: It’s hypoallergenic, essentially rust-proof, and has an extremely high tensile strength ratio. And even better? They didn’t cheap out and run with Grade 2 titanium which is considerably more malleable and easier to machine. DUNU’s making sure their stuff lasts a long, long time.
Lets’s quickly talk about their proprietary output swap system. This is a really simple, yet cool feature that the DUNU cables feature. There are 2.5mm, 3.5mm, and 4.4mm plugs that you can swap at will. All you have to do is line up a small notch and from there it’s plug-and-play.
