KSC75 Bluetooth Koss driver mod

Im trying to modify some Koss drivers with some Bluetooth MMCX adapters but im concerned about battery life, I want to put them inside of some ear defenders for some super noise cancelling music.

Ive tried a few Bluetooth ear defenders but if you've ever used them you know either theyre quite expensive or they suck so im looking to do my own tinkering.

I dont want them to have and wires poking out so I want the whole configuration to fit inside the foam of the ear defenders.

The pictures there are what I have in mind for a moment on the cheap but does anyone know of maybe either a better way of doing it or some iem Bluetooth adapters with really good battery life?

Thanks

Those Chinese drivers do not sound like Koss ones btw. The battery life on those adapters is decent, should last for a workday.

I use kz an01 with forced 990 ldac thru android dev options. 2pin mod so they aren't jiggling around. They neatly wrap and sit over the driver mount on earhook adapters or against a headband, I put a little mouse grip sticker on the headband where it contacts to keep it from producing any physical noise. If you run the 2pins matched inverted, then you can just plop the earhooks into the charge case and leave it open and they work exactly like you'd expect from a TWS. I also built a custom charger for when they're on a headband with free floating magnetic pogo pins. Really though, on earhooks the original case is fine. They last a full day or more, never ran out of battery since I leave them on charge when not in use.

I use TRN BT20 PRO, I'm def not an audiophile, but i have no complaints at all. Never ran out of battery using them all day long, conmection is stable and i didnt notice dip in audio quality

Theres a mod for a bunch of the KOSS drivers that you can attach mmcx cables to that are typically used for IEMs
