Hidizs DH1000

The Hidizs DH1000 is a DAC/Amp that uses a balanced circuit, featuring Dual ESS ES9018K2M and Dual ESS amps, it provides balanced audio as each DAC decodes each channel. You also benefit from the Balanced 2.5mm audio jack to get the best, balanced audio quality, or you can use your current 3.5mm headphones or cables with it.

The Good:

  • Awesome, balanced sound.
  • Excellent channel separation.
  • Extended trebles.
  • Compatible with USB Audio Class 2 devices like Android and PC.
  • Zero delays.
  • ASIO Driver is available.
  • 2.5mm balanced and 3.5mm audio jacks

Hi everyone,

Today, I’d like to show you some pictures of the Hidizs DH1000 Circuit Board.

We need to take out the top and bottom glass first. You can remove the top glass if you want to see the main chips, and you can remove the bottom glass to take a look at the battery. Please note that the glasses are completely glued, not just the borders, so you’ll need something that you can use to carefully remove the glue behind:

Once the glass is removed, there’s a metal shield protecting the circuit board. Removing it is as easy as taking off the 4 screws it has. Note that the surface is full of glue:

Once removed, the beauty of the circuit board awaits:

The main chip is a Hiby Music HBD150A:

The second chip is a SmartAction SA2000 chip. From there, it goes to the dual ESS ES9018K2M DAC’s (Digital Analog Converters):

Here’s a closer look to the dual ES9018K2M decoder chips as well as the dual amp chips:

On the other side, there’s the battery. It can be detached but it seems to be glued, so it needs to be carefully removed:

Here I have the unit connected to my PC using both USB’s and a headphone connected:

And here’s the battery side:

It’s difficult to know if the unit is charging or not, because my unit has a fault in which the LED is always turned on, and the charging is extremely slow. Also, for now, the only way to power it is to disconnect the battery, press and keep pressed the power button, then quicly connect the Power USB cable without having the data cable connected. This will make the unit turn on. Once it’s on, the battery can be connected and once it is connected, the data cable can be connected. Otherwise, the unit will turn off almost immediately, maybe because it doesn’t have enough power to be kept on, which is why the battery needs to be connected.

I wonder if Hidizs will release an updated version (maybe a Hidizs DH2000?) which fixes this battery defect which some users have been facing. It’s just a matter of time to see what amplifier they do next, as this one sounds very good and I enjoy the sound. It’s unfortunate that it has such a battery problem. Anyway, I’ll keep using this product, again, because I enjoy the sound 🙂

Hope you enjoyed the photos and if you did, don’t forget to follow me on Instagram!

The UGREEN USB to Micro USB Y Cable

The UGREEN USB to Micro USB Y Cable

Hi everyone,

Today, I received the UGREEN USB to Micro USB Y cable and I’m going to show it to you and also my use of it.

The UGREEN USB to Micro USB Y cable is a USB cable that splits into 2, and yes, you can use it to connect 2 devices simultaneously and transfer data to them because the cable acts as a USB Hub. This is the cable:

Now, this is where I show you my usage of it. As you may know from an earlier post, I own a Hidizs DH1000 Digital-Analog Converter and Amp. This Amp that I have has a problem with charging, and that’s where this cable comes handy. The DH1000 has 2 USB ports, One is for data and the other is for charging. This cable is the perfect solution to keep it powered on while enjoying music.

Here’s a picture of the cable connected to the DAC/Amp turned off and charging:

Now, it’s important to know that this cable consumes around 0.05 to 0.08A (amps), so keep that in mind. This is due to its integrated Hub.

With the Hidizs DH1000 turned on, it consumes around 0.20A:

It works wonderful!

Here it is connected directly to a USB port of my laptop:

And of course, it’s compatible with my Hiby R3. Notice the USB logo on the top left, meaning it has a USB DAC connected to it:

And there you have it. The cable does the purpose it’s meant to do. It’s working fine with my amp, and that’s a wonderful thing. However, when it’s connected to the Hiby R3, the DAP’s (Digital Audio Player, the R3) battery will discharge more quickly. Still, it’s a very nice cable for short listening sessions.

You can buy this cable on Amazon at the following link:

Hi everyone,

As you may have seen from my previous posts, I’ve been developing GUI’s for FLAC and Opus, which are 2 great audio formats. This, of course, means I listen to music, and to enjoy them, I use my Hidizs DH1000 USB DAC/Amp. The sound it produces is awesome, but I’ve been having issues lately due to it charging very slow.

Because the unit charges very slow, at just 0.09A according to my meter, I needed to figure out a way I can keep using my DH1000 without sending the unit back to China for replacement. Of course, this is easy, because the unit features 2 USB, you can just connect 2 MicroUSB cables and have the problem solved. This would send power to the unit while you enjoy music, but what if you only have one USB socket available? Yes, you can use a USB hub, but I don’t think it’s recommended to use one because it would have a Hub in the middle and not a direct connection to the DAC, and also you’ll have several cables around.

To do a simple test, I purchased the PortaPow USB Meter which features 2 USB-A ports. One is for charging only and the other allows data transfer and charge, so the connection I’m using is the data port to the DH1000 data port and the No Data + SmartCharge port to the DH1000 microUSB charge port:

Using the PortaPow to provide Data and Charging to the Hidizs DH1000

With the meter, I could see that the unit is working and it is also drawing power from the USB port, which is what I initially wanted.

I also tested this with my Hiby R3 as you can see below:

Using the PortaPow with the Hiby R3

The Voltage seems to be below 5V, but it’s working fine. The downside is that the R3 battery drains faster, but for short-term music listening, this is fine.

My next step is to find a good USB-A to Micro USB Y Cable that provides charging and data to keep using my DH1000 for as long as possible.

I hope you enjoyed this post and found it useful. I know there’s some of you that have the DH1000 Blue Light issue, and that’s why I also have the rubber band that came with my unit in the DH1000, because I also have that issue. But hey, at least the DH1000 is still working great!

See ya in my next post!

The Hidizs DH1000 DAC / AMP

The Hidizs DH1000 DAC / AMP

Hi everyone,

In this post, I’d like to talk about the Hidizs DH1000 which is a Digital to Analog converter and an Amp for headphones.

This device is a USB digital to analog converter (DAC) that can improve the sound quality of the music thanks to its advanced dual ES9018K2M DAC chips as well as its dual Amp chips. It features a balanced 2.5mm headphone jack as well as the standard 3.5mm headphone jack and works with any device that supports USB Audio, be it a PC, Mac, Android, or a music player that supports USB DACs.

As you may have seen in my previous posts from several months ago, I like to listen to music a lot, so I decided to pledge to this product originally launched in Kickstarter.

Here are some pictures of the DAC:

Plugged via MicroUSB to my PC

Plugged to a USB 2.0 hub and also to a charger

Plugged to the Hiby R3

The device features dual USB ports for simultaneous music playing and charging. It has to be noted that this is not only for music but for anything audio-related since it is detected as USB Audio Class 2.0 device in Windows as well as an audio output in Android. For iOS devices, you must use the Hiby music app.

The other device shown alongside the Hidizs DH1000 is the new Hiby R3 player, which I’ll show you in another post.

How’s the sound quality?

Way better than using the headphones plugged into my phone or other audio devices. For me, everything sounds very detailed and impressive. You can head the vocals very clearly, be it a male or a female singer. The treble also sounds very nice, and the bass is perfect. Of course, everyone will have different opinions on audio quality, but for me, this sounds very authentic and provides an awesome sound.

One thing that I also like about this DAC is that the volume buttons are independent of the source device. This means you can change the Hidizs DH1000 volume and it will not change the volume of the device it is connected. I usually just set the device to output audio at 100% and then control the volume in the DH1000 DAC.

Where did I heard about this product?

Kickstarter. I always browse the “Technology” category in Kickstarted and almost every month I find something I like. That’s where I found this DAC there:

To conclude this post, here’s the unboxing video that I recorded which shows the DAC, the box, and its content. Enjoy!

In the next few days, I’ll share with you the unboxing video and photos of the Hiby R3, an awesome portable music player filled with lots of features.

See ya next time!
