Plenty of good features packed in so small ultraportable DAC. When looking at stated figures and comparing to other DAPs in Hidizs lineup it gets obvious that AP80 stands in between AP60Pro enhanced entry-level player and flagship AP200 DAP. Sound quality is what bothers us the most and we would investigate on it a bit later.

BTW: LDAC function in AP80 is also expected in the nearest time as Hidizs already applied for the certification process.

Box contents:

Hidizs sticks to their recent brand design guidelines and ships AP80 DAP in black satin box with logo and technical specifications embossed with silver paint. Strict, neat and solid box to prevent the device during the delivery process. In addition to that, AP80 is securely held by foamy podium.

Box contents are regular:
AP80 DAP with preapplied screen and back glass panel protectors
Extra screen protector
MicroUSB type-C ->USB A cable (file transfer, charging, USB DAC)
MicroUSB type-C ->microUSB cable (USB DAC for microUSB OTG devices)
Warranty and QC cards
There is no microSD card shipped along with the unit, neither it features internal storage. It means that you should bother to get one up to 512GB and feed it to player.

Design and materials:

We like the overall approach of Hidizs to design as well as we like the new tendency towards implementing more complexity… Very familiar feel of perfectly crafted alluminum case with the introduction of further tiny details and much more efforts spent to shape the right part that includes jog dial and additional control elements.

Not a mere squre or rectangle anymore but the new complicated and organic look that attracts the attention from the first glance.

AP80 has unibody alluminum chassis with gorgeous screen almost covering the entire space at front and curved edge glass panel covering its back. It looks astonishing and creates an image of very valuable possession. Total device weight of 70g and cold solid feel in hands also add up to build perfect first impression. All elements are perfectly aligned, having no free play.

MicroSD card slot is located on the left edge, microUSB type-C port and 3.5mm headphone output at the bottom. But the most important is the right side — it has newly introduced volume jog dial and 3 additional control buttons which are:
Next (long press: seek forward)
Back (long press: seek backward)
Besides volume control, jog dial elements serves the funtion of ON|OFF switch. Press and hold to switch ON and OFF. All buttons have pronounced clicks and are easy to operate in pocket.

Jog dial is a good addition to such kind of device and serves its role well. Although, we would say that it is a bit smaller than expected and people with large fingers would have some hard times operating it. Rough and textured jog dial edges should help with that. The good news are that when you’ve turned jog dial a little bit to change the volume — you can contunue changing it on screen by moving finger up and down.

What really shines in this unit is a its screen. A giant step ahead comparing to AP60 series DAPs or even to AP200. 2.45″ size, touch-sensitive, 360×480 dots resolution, IPS panel with large viewing angles, excellent crispness, high contrast and brightness values… When placed next to prior DAPs, AP80 screen revelas all advantages over previous models. It has the largest brightness and contrast levels plus the extreme viewing angles won’t invert or bleach the image. Touchscreen sensitivity is high. We haven’t spotted and problems or difficulties while operating UI smallest elements.

In overall, AP80 is the most universal and convenient DAP from the whole Hidizs lineup. It features physical control elements along with the sensitive touchscreen and it also introduced a new beautiful design with handy volume jog dial element. Hope to see the future product from Hidizs utilizing the same approach.

UI and performance:

BASED ON 0.07beta FW

Perhaps, the most responsive DAP from Hidizs until now. Even the initial loading animation is unexpectedly fast… as well as total OS loading time of <8 seconds.

AP80 features modern Linux-based HibyOS UI with logical touch control gestures. If you are using any smarpthones based on iOS or Android — you’d feel like being home. Each feature or program is represented by a separate icon. All general device and audio settings are gathered in Settings Menu, whereas all deep and more precise audio preferences like EQ and filters are located only in HibyMusic application. By the way, HibyMusic looks very similar to its versions for other platforms. No surprises here. It also features such function as HibyLink that allows you to control this DAP from a smartphone.
