The good news is that this set does have a pair of Audio Out jacks.

But no manual I found showed how to turn them on. The output is at most 500mV so I can't guess if that's enough for your headphones but ASK SONY if you have to turn on some External Speakers menu thing.
I read one manual but that's it for me.

Hello,
I am a newbie here and I have a technical question.
I have a HX800 that I purchased a couple of months back but already the headphone jack no longer works!
Anyway I purchased a RCA to headphone (female) cable and have connected this to the two RCA outputs (red&white) but this does not work. I tried with simple headphones and with sennhiser wirleless headphones (with voloume control) and no sound??
Anyone know if this is a problem with my equipment or do I need an amplifier or something??
Thanks for your help.
Regards
john
