Please note that at the time of this writing, the R6 is no longer available for purchase on Indiegogo and impressively ended up being funded 582%.
This Hiby R6 was purchased as a backer on Indiegogo for the purpose of a review, and thus there is no monetary incentive for providing a positive review. My model is the Black Aluminum, has over 250 hours of clocked usage and it's pictures may not look exactly like others due to sample variance (and maybe lighting). More information on the how I arrived at my findings are at the very end.

The Hiby R6 came in a sealed hard cardboard box where the DAP sits on top of the other contents (from top left to right): Black thin cardboard separator with the micro SD card ejector pin clipped on it, a Quality Control pass card, (bonus) tempered glass cover, plastic screen protector, manual, warranty booklet. (Bottom, left to right) DAP foam Tray, 3 extra Hi-Res audio stickers, the branded Hiby charging cable, 3.5mm to COAX cable and (bonus) silicone case.
The Hiby R6 itself is a solid piece of milled aluminum with no jagged or sharp edges that feels good in hand with enough heft and weight to be significant but not a burden when carried. When you first get it, there's a matte protective sticker on the screen with printed guides for the R6 parts. Note that a screen protector should have been factory installed on the R6 but mine did not have one, this is fine since I would have removed it anyway in deference to the tempered glass installed above (I like the smoother glide on glass than plastic).
So on the right side from top to bottom:
Power - For turning the unit and screen on or off, it has a little LED indicator that shows the status of the R6 (Red blinking is charging, solid white is DSD audio playing, green is 24bit, blue is 16bit and lower) and this light can be turned off if you wish.
Previous - With the screen on, holding it down pauses playing and "rewinds" the time bar till it is released. If pressed once with the time bar at 10 seconds or more, it will go to the start of the song, otherwise it will go to the previous track. With the screen off, pressing it once does the same thing as when the screen is on, but holding it down (no matter how long) will move the time bar around 3 seconds back, you can repeat this to be able to go back through a song.
Play/Pause - is self explanatory and does as advertised with screen open or closed.
Next - With the screen on, holding it down pauses playing and moves the song "fast forward" till you release it. Pressing it once will skip to the next song whether the screen is off or on. When the screen is off, holding it down will move the time bar forward by 3 seconds while the song continues playing. You can repeat this quickly several times to move the time bar forward.
USB C port - For charging, USB output (transport) and DAC (usb input).
From (bottom) left to right:
2.5mm Balanced Output - Plastic rubber ring around the plug is not so pretty but it works.
3.5mm Single Output - Gold ring makes it look sturdy and pretty.
3.5mm Line-Out/COAX - By default the software is at Line-Out mode for this identical gold ringed plug, which means max ear busting volume, be careful!
Volume Up - Turns the volume up once per press, holding it down moves the volume continuously up but only when the screen is on.
Volume Down - Just the reverse of Volume Up.
The glass back is covered by a plastic screen with 2 stickers, (white sticker) barcode with model number & date of production, (black) is the same info found in English printed under the glass. As much as I like the feel of a glass screen over plastic, I just took the 2 stickers off and kept the plastic to help protect the beautiful glass back as there is no included back protector. The front and back glass panels are 2.5D curved glass, which may make fitting a generic, cut to fit protector fiddly as there is no defined edge and that it may look like a floating square panel (you'll see it here and in subsequent pictures.)
