    My dad is slightly deaf, which he's entitled to be because he's 92. This means the TV can be on very loudly at times, which annoys my mum, and probably the neighbours too. I looked at branded bluetooth TV listener devices, but I'm reluctant to spend £300+ on a pair untested.

    I bought a pair of bluetooth headphones for about a tenner, and I bought an audio to bluetooth adapter which plugs into the TV's audio output (RCA) connectors. The problem is connecting (pairing) the two items over bluetooth. Both items need to connect to a bluetooth device that can input the pairing code (0000), neither has the means to generate or input that code.

    Any ideas how I can pair these together, particularly methods with which I can instruct him over the phone, in case they become 'un-paired' in the future? He does not have a smarty-pants phone.

    I am in the same boat with your dad, the rest of the family complain at how loud I have the TV too.

    Bluetooth is carp!
    You have to keep reconnecting the headphones to the sending device which is a right pain.

    Get your dad a pair of RF headphones, they will be constantly connected to the transmitter which (if you get the right ones) can connect to your TV via the optical port which should then still allow audio out of the tv speakers at a lower volume for the wife.
    This is the solution I am looking to get for me and another for the MIL who has a similar issue.

    I was looking at bluetooth headphone reviews on Which. Some of them have an app which is difficult to use or doesn't work, and there is reference to using a phone or laptop to make the devices connect. It varies by Alexa, Google or the other one.

    I thought that once you have linked them, they stay linked. If so, you or some person with a smartphone might be able to call in and do it.

    There lies the problem; each item will connect to a smarty-pants phone, because a phone has the means to input the pairing code (0000). Neither the headphones nor the transmitter have the means to enter that code, so I can't pair them to each other.

    Anyhow....
    Thanks to all for their contributions.
    I have just bought him a set of secondhand wired headphones from fleabay for £20. If he gets on with these I'll probably hunt around for some expensive digital rf or Infra-red headphones so there's less chance of tripping over the cord....and if he doesn't use them the cord is long enough for my mum to throttle him. Either way the problem is solved!:sneaky:

    Over and out..

    Are you sure these are audio OUT and not audio IN?

    There are very few TVs made within the past decade which still feature an analogue audio out connection on RCA (phono) connections. Your dad's could be the odd exception of course, or the TV could be old enough that it does have audio out, but it's worth checking. You didn't list your dad's TV model, so it's a bit of a question mark and a possible roadblock to getting BT working for him; or any external audio device via this connection.

    Lots of folk assume that the red and the white RCAs they see on the back of a telly will give them a signal out. They don't realise that these connections are directional i.e. if it's marked "AUDIO IN" then it's for getting a signal IN TO the TV. They aren't bi-directional.

    The Techwalla article even gets this wrong(!), or at least gives very confusing information, especially if you're trying to get audio out from the TV to a speaker or a pair of headphones

    Any port on the TV which is marked "(something) IN" is not a connection for getting anything OUT unless it's the HDMI ARC connection. That's the only modern bi-directional connection. Fully wired SCART - something else very rare on modern-ish TVs - is the other possibility, but only for sound from the internal tuner. It wouldn't work for externally connected sources or streaming apps for example.


    List your dad's TV model, and if you want then I or someone else here can check for you.


    Checking this is pretty much essential before then going on to try to get BT working. Even if you establish a BT link, if there's no signal getting from the TV to the transmitter then you won't get anything in to the 'phones, and then probably think it's a BT problem when it's really a source signal issue.

    You can separate the headphones jack volume from the TV volume and run the cables around room to the seat. This works better for some vs wireless.

    Also Bluetooth adapters can be senders or receivers. You need a sender which tend to cost more. That will send the sound via bluetooth signal and the headphones will get paired following the headphone pairing guide, and to date not any of my headphones or Bluetooth ear buds need a code as there is no way to enter a code on headphones. Double check you have a bluetooth audio sender plugged in TV...

    @Lucid, thanks for your detailed post (number 6), but it has somewhat missed the point. I will address the source of the output from the TV (whether from RCA, headphones jack, SCART, or other) once I have bluetooth connection between the transmitter and the headphones.
    I don't have dad's TV model (yet), he lives 200 miles away. I'm using my own TV (Hitachi 48HK6T74U) in lieu of this. My TV has a 3.5mm stereo jack headphones socket, and I feel sure dad's will have the equivalent...the only thing which may cause a problem is if the headphones socket on dad's TV mutes the main speaker when it's plugged-in (which it does on my Hitachi), meaning that mum can't hear it when dad can! This may be overcome by breaking out of the SCART lead from his Humax PVR9300T (hard disc recorder) before it gets to the SCART to HDMI converter (his TV has no SCART connector). I'm capable of doing that; it's just the original question that remains.

    I want to close this thread now, and come back to it when on-site in a few weeks.

    In the TV sound settings separate the jack and TV volume. This won't mute TV when you insert 3.5mm jack, so TV speakers and headphones work at the same time. Most Tvs have had this functionality for years plus a hidden hotel settings that can be useful for some if you look online but that's not what you are asking. Look for don't mute TV when jack is interested in settings

    Wayners, what you are saying is that when plugging in a headphone, the TV speakers will not mute.

    This is just not the case!
    While there may be some TV's where you can still get sound out of the speakers in general plugging in headphones will mute the speakers.
    I was looking at new TV's in curries recently and despite looking for it I could not find this functionality on any.

    Sony Tvs are best for this option. Our old Panasonic plasma will but out cheaper LCD Panasonic in kitchen won't
