Hidizs AP80 Copper Review

Hidizs AP80 Copper Review




Hidizs Technology Co. Ltd. was founded early in 2009 and is specialized in portable audio equipments such like DAC’s, DAP’s and IEM’s.

Hidizs has released the Copper and Stainless Steel versions of the original AP80 which has had an Aluminum chassis. The AP80 Copper which I will now review for you is an ultra portable DAP that has the same internals like the first AP80. It has some nice features like the ES9218P DAC Chip, Native DSD Support, 2.45 inch Touch Screen, Bi-Direction Lossless Bluetooth Connectivity, FM Radio and a Step Counter..


I would like to thank Hidizs for providing me the AP80 Copper as review sample. I am not affiliated with Hidizs beyond this review and these words reflect my true and unaltered, opinions about the product.

Design, Buttons and Build Quality:

The Hidizs AP80 Cooper is a Digital Audio Player with a very compact design and small size by 58x49x13.5 mm. It is a bit weighty (approx 100gr) due to the copper chassis but feels very solid in my hand. The overall build quality is pretty good, while the slightly aged surface and the natural cooper color of the chassis is quite beautiful.

On the front of the device is the 2.45 Inch Touch Screen of the company Samsung with a Resolution of 480×360 Pixel. The screen is small but quite responsive and visible under direct sunlight conditions.

At the back of the AP80 Copper is a glass panel that shows the product brandings and some of the industrial certifications.

The top of the device is blank while the right surface features the volume wheel that acts also as power on/off (long press action for 3 seconds) and screen on/off (short press action) button. The volume wheel is fairly precise. Here are also the next/fast forward, play/pause and back/fast back buttons that are small but easy to press.

On the left side of the AP80 Copper is the micro SD card slot that supports cards up to 1TB.

At the bottom of the device are the USB Type-C female connection that reacts as digital out for USB DAC/USB Audio functionalities, charging port/data transmission and the 3.5mm TRS headphone jack that shares also the LO (Line Out) output that you can select from the settings.

Hardware and Software Features:

The Hidizs AP80 Copper is a very compact Digital Audio Player with a pretty small size which has some nice hardware & software features that I want know share with you.


A. Processor:

Under the hood of the Hidizs AP80 Copper is the X1000 CPU of the company Ingenic Semiconductor with a processor speed of 1.0 GHz. It has an energy efficient MIPS32 XBurst RISC core with double precision hardware float point unit for low power consumption.

The X1000 was good enough for a fluid operation of the AP80 Copper.


B. DAC/AMP Section:

The Hidizs AP80 Copper has the ES9218P SABRE HiFi SoC under the hood which features the company’s patented 32-bit “HyperStream” architecture that can support up to 32-bit 384kHz PCM and DSD256 to deliver up to 130 dB SNR and -114 dB Total Harmonic Distortion plus Noise (THD+N). It also supports popular high resolution and lossless audio formats including DSD, DoP, FLAC, ALAC, AIFF and WAV.

The Output Power      PO      : 90mW@16 Ohm / 80mW@32 Ohm
Output Power             BAL     : 240mW@16 Ohm / 240mW@32 Ohm
Output Impedance     : PO≤1.0Ω(32Ω loaded) /BAL≤2.0Ω(32Ω loaded)

The AP80 Copper has a build in amplifier and LPF (Low Pass Filter), which is implanted to the SoC (System on a Chip) together with the ES9218P and output Switch. The amplifier has an output impedance of <1Ω and a power output of 70mW + 70mW @ 32Ω (THD+N<1%).


C. Connectivity:

1. Wired:

The Hidizs AP80 Copper features a 3.5mm unbalanced (TRS) headphone out that works also as Line Output (LO) that can be easily switched over the short settings menu.

The Hidizs AP80 Copper can also be used as an asynchronous USB DAC with both Mac’s and Windows PC’s. With Mac computers, you can just plug-and-play the AP80 without the need of a driver installation. With Windows PC’s you need to install the driver, which you can find on Hidizs website.

2. Bluetooth & Bi-Directional USB Connectivity:

The Hidizs AP80 Copper uses Bluetooth 4.0 and supports also “Bi-Direction Lossless Bluetooth Connectivity” which can be used to transmit or to receive/stream your music from any compatible device. This is a nice feature if you want to listen songs from streaming services like Spotify, Tidal, Apple Music, etc. The actually supported codec’s are LDAC/aptX/aptX HD and SBC.

The connection between the AP80 CU and my Samsung Galaxy S9 Plus was pretty stabile during my tests, without to show drops and noise issue from a distance up to 9-10 meters.


3. UAT (Ultra Audio Transmission) Support:

The Hidizs AP80 Copper supports the so called UAT codec (Ultra Audio Transmission), an audio coding technology that was self-developed by HiBy that supports up to 192 kHz sampling frequencies or up to 1.2Mbps bit rates which is a pretty interesting feature.


D. Battery Life:

The battery life of the Hidizs AP80 Copper is quite good for such a small device with a build in battery of 800mAH and output power of 70mW per channel @ 32ohm.

I have tested the battery life of the AP80 Copper under the following condition and file formats.

DUNU Titan 6 / Volume 65 out of 120 / Screen Off

  • Flac 16bit/44kHz        : approx 10 hours
  • Flac 24bit/192kHz      : approx 7 – 7.5 Hours
  • DSD64 (.dsf)              : approx 6 – 6.5 Hours


E. Other Features:


1. Pedometer:

The Hidisz AP80 Copper has a built-in step counter sensor, while the program will run in the

Background after activate it under the step counter APP. You can view your steps in real time and it supports also the viewing of historical actions.


2. FM Ratio:

The AP80 Copper features a FM radio function unlike many other product in the market. To activate the function you need to insert an earphone that will be used as antenna. The radio signal and sound quality is on an average level.


F. The Software:

The Operating System (in short OS) of the Hidizs AP80 Copper is HiBy OS 3.0 which is a Linux based software that was developed by the company HiBy. The GUI is pretty fluid with minimal/low lags and should satisfy most of its users.

The Main Menu shows you some icons/shortcuts like Player, FM, Step, Bluetooth, System Settings and About.

The Player shortcut links you to the player interface which is minimalistic but clean. Here are a number of swipe gestures you can do to open some new windows.

If you swipe from left to right, it will appear the player fine tuning menus where you can see the Hidizs logo and some settings like Update Database, MSEB (Mage Sound 8-Ball DSP Tuning), Equalizer and Play Settings.

If you slide up from the bottom of the screen, you will see shortcut functions which will give you access to quick adjustments like screen brightness, volume, gain, Bluetooth on/off, play/pause, etc.

You can set your EQ settings manually or can use some presets like Rock, Pop, Dance Metal, etc.

Normally, I don’t like to use any EQ settings, but the MSEB (Mage Sound 8-Ball) feature of the AP80 Copper, which is a combination of multiple algorithms based on parametric equalizer (PEQ) and sound field adjustment (in short a DSP tool) works pretty good If you like to transform the sound of your device.

You can turn on and select several Bluetooth functions under the Bluetooth Menu. As I have mentioned before the AP80 Cooper supports lossless transmission protocols like apt-X, LDAC, etc. and features two-way Bluetooth transmitting which can transform it to a so called Bluetooth DAC. These features can be enabled under this menu.

Other options like the FM radio, Step Counter and System Settings can be activated and adjusted under the main menu.

The Hidizs AP80 Copper has also a clock feature that is implanted to the main screen.


HiBy Link Application:

You can control the Hidisz AP80’s music wireless directly from your phone with the HiBy Link applications. I have tested only the Android version that you can download from the Google Play Store.

The Sound:

The Hidizs AP80 Copper is a DAP with a slightly warmer than neutral tonality that shows deep lows, a soft and musical midrange and a treble range with good extension and control.



The AP80 Copper shows a good subbass depth and extension, with an intensity that is not too high or to little. The tonality of this area is in general soft and warmish, while it has enough depth from instruments like cross drums up to the synthesizers.

The Hidizs AP80 Copper doesn’t add additional subbass coloration to your earphone/headphone/iem, which means that the performance strongly depends of the gear you will use with it.

The midbass region on the other hand sounds pretty strong and emphasized and shows a lightly warmish, smooth and musical tonality. It shows slightly more quantity than the subbass range and is in many situations quite controlled.

The bass of the Hidizs AP80 Copper is controlled and pretty successful in terms of clarity & detail, which is one of the important plus points of the AP80 Copper.
