AZ09 Pro into wireless headphones? Possible?

Submitted by xthakx t3_1261h6a in headphones

I have a AZ09 Pro that snapped on me so I took it apart into a project. I was thinking is there a possible way to get the internal of AZ09 Pro and power headphones such as HD 560s with it. Hope this post summon all of the electronic engineers in here.

In the picture, the two wires represent 2 pin connector. So I wonder is there a way to connect it to headphones

they will lack power to drive a big headphone like those, could try to use them to drive another iem since those use less power.

Yeah maybe I just try to fix it by connecting it to another 2 pin cable

The HD560S is 120Ω and quite high sensitivity, many people report running it off a phone fine and the AZ09 Pro has more power than most phones, even more so in high power mode (triple click on the left). I don't have the HD560s but it almost certainly would have enough power for them.

That good to hear, I still wonder how convert headphone like 560s into wireless with the AZ09 Pro

It wouldn't be trivial, you'd need to open them up and find some space for the unit inside, wiring the + and - to the driver. You'd need to mod the case to connect the charge points to something on the outside to charge them. Having these modules in there could affect the frequency response too as it's an open back.

Someone did a very involved mod with the TRN BT20S Pro and the HD660S, which involved 3D printing a load of parts and re-fitting these into them

Even in this case though it would be easier as the 660S is at least a dual sided headphone to start with, the HD560S is single sided so you have two mono adapters (for L and R) but you only have a port on one side. So you'd need to get more involved than that and I think re-wire it internally.

If you're super into modding/DIY projects. But it's not some easy thing to make this work.

Easiest way to make the HD560S work, as it's single ended, is use a single cable output stereo BT adapter and plug it into the one side, and then tie the adapter to the headband or something.

Very informative. Thank you! I will see what I can do

I have tried putting kz wireless aptx cable modules into headphones (on 32 ohm ones). While it works and sounds great, the battery is just too small. Maybe good for just a couple of hours and that's it. Replacing a bigger battery isn't also guaranteed to help, if the module will just charge for a specific amount of time and will not fully charge it. If you really want I suggest you test it.

Plus, usually you can't connect both gnd/negative of the left and right outs (probably th + side too on these tws). So if you plan to still connect via a trs ended cable, use a trrs jack or balanced connections on the headphones.

Your battery looks swollen up. If that's the case, immediately remove it as they can blow up and contaminate your headphones with acid. You don't want that.

That what I thought as first but I’m not sure if it actually swollen up because it still fix in the case.

I would put some kind of bag around it because these boys literally explode and spread their gunk everywhere. Be careful
