Just got the ZEN in yesterday and took a bunch of photos for anyone who's interested. Nice stuff! Mine was a pre-order so I also got a free case and USB-C quick-switch connector. Here are some of the quick pics I took yesterday while opening everything up:

So, let's ignore the fact that I went straight for the USB-C connector and opened that up first. (Heh).

Lets get the plastic off the box and take a look inside:

And behold!

Under the ZEN, you'll find your quick-switch connectors, a nice plastic container for tips (labelled S/M/L too!), and a black box, containing more goodies:
IMG_3033.JPG

Black box contains the case, inside of which you will find additional accessories shown below (including some additional eartips):

Interesting foam tips, I'm not familiar with these. Also, a nice touch for the plastic eartip case to have the S/M/L indents on it!

Some additional photos of the body, including the bore length:

The ZEN is actually quite shiny - note the flash creating a little effect here (and the fact that my macro lens shows my fingers smudging up things slightly). Since this is a pretty close-up macro lens, I wouldn't worry too much about the ZEN looking smudged later on, but I appreciate the reasoning behind including the soft cloth for wiping the ZEN down - it's very high quality and a nice touch.

With eartips on, and a picture of the USB-C quickswitch connector:

And with my custom eartips on - getting ready for a listen!

IMO the ZEN is really pretty - it feels very well made, of high quality materials, and the finish is quite nice. I think the pictures I saw before didn't quite do it justice.

Time for me to do some listening to see what the ZEN is all about : ).

Cheers all!

I appreciate DUNU's build quality (a characteristic I am constantly surprised many enthusiasts can be pretty casual about). I care about design and fit & finish; call me shallow, LOL.

design, fit, and finish are usually highly correlated with reliability.

Interested to compare notes with you on the ZEN vs. the Luna.

I also got a camo green case as an extra- it has some neat color shifting (?) qualities that I didn’t quite notice as much before until I put it under camera/light:

Quick video of how it looks as I rotate it with some direct overhead light:

Neato!

I pop the Zen in my ears, before an overnight seasoning session tonight and Zen has caught my attention.
