I guess Skyzone rushed the release of the Cobra X and forgot to design the earphone jack unless they were unable to reliably fit it in the pcb design.

This was not their first google and its a surprise they didn’t realize including such a feature.

I agree that it's not an ideal solution but at least there is an option to tap into the audio feed of AV jack rather than no option at all. I'm sure it wouldn't have taken much for Skyzone to just put an additional mono or stereo 3.5mm jack socket and a simple inline rotary volume control knob on the goggles even if it was just on a mini daughterboard rather than the mainboard, so it's a bit disappointing they didn't do that especially as the Cobra X is considered to be premium goggles in the box goggle line-up.

@Cyfly - that's great write-up on your blog Hopefully it will help out some others who want the same functionality.

FYI

Snow melted in april and since then I used the Cobra X about 8-10 times, relatively problem free.

I only had hot battery, very short battery life happen once. Power off, swapped battery and it was OK.

I am using Sanyo 3500mah GA. I estimate 40min, maybe less with DVR recording. I swap out when OSD shows yellow low battery. At home, the 18650s charge aboit 1600-1800mah... ie half capacity.

These goggles dont like "saggy" 18650 like Samsung 3000mah 30Q. You need lion that maintains high voltage under load.

I have bunch of LG MJ1 3500mah, but havent tested them.

Im also considering 3D printing adapter for 26650 (5200-5500mah!!!) or 21700.

great to hear some people could enjoy the goggles i couldn't, skyzone "support" are not willing to repair the v1 goggles, i was very patient with them, until my patient ran out, i resend all the emails to getfpv where i bought the goggles, they respond that were very sorry for what i passed with the product and they refund me all the amount!!!
I bought some 1.3ghz stuff and i am waiting for the release of the new fatshark googles.
I am not going to buy anything from skyzone again

The goggles are supposed to charge the internal battery, right? At least I remember them doing it in the beginning but now it doesn't seem to work. No lights light up to indicate charging.

 I have CobraX V1 and they are supposed to charge 18650 but since 18650 in CobraX causes nothing but problems I only use external battery packs.
  Once I stopped using 18650 in CobraX they started working consistently and predictable.
