Hi everyone,

Today morning, it came to my attention that there was a new firmware update for the Hidizs AP80 Digital Audio player. I downloaded and installed it, and surprise! We have LDAC support now! This means that it can be used as an LDAC bluetooth receiver and should also work as a transmitted, altough I haven't tested this mode yet.

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:

Unboxing the Hidizs AP80 Digital Audio Player

Hi everyone,

Yesterday, I received the Hidizs AP80 Digital Audio Player from their kickstarter campaign. After that, I received a tracking number which is of no use because of course, I already have the unit here and it shows as "Delivered", so it came as a surprise and was shipped by Amazon since they fullfill US orders from them.

So, here's my unboxing video that I recorded of this tiny (smaller than I expected) audio player. Enjoy!
