Headphone recommendation for OLED C7P

I have a pair of wireless headphones from Sennheiser (RS160) and have trouble hooking it up to this TV as it doesn't have a headphone jack. Is there any way to get it working?. If these headphones are incompatible with the TV what headphones are recommended for watching TV/movies that will not mute the sound on my sound system?.

I don't think the RS160 has an optical input and buying one would cost as much as a pair of low cost bluetooth headphones.

The TV only outputs audio digitally and the 160 only takes it in analog. Maybe one of AVS's tinkers might suggest a DAC for you - I dunno.


Don't know why I can't load the LG's US model page, but look at what this AU LG site says in its footnotes:

Really?

I'd email LG to see if you have any limitations you'd rather be aware of...

at the very least a $10 optical dac and a 2x rca to 3.5mm or w.e the rs160 takes may work. Would have to confirm what audio stream the tvs optical port outputs. 2.0 pcm or 5.1 ac3. If its 5.1 ac3 then you would just need an optical dac with a decoder. decoder

It's an LG SJ9 soundbar i want to use headphones and also have sound from the soundbar at the same time. Some headphones will automatically mute the sound from the TV, i don't want that.

It's correct the LG C7 uses bluetooth technology to hook up wireless headphones. The DAC i was looking at costs as much as a bluetooth headphone so it's probably best i purchase new headphones. Do you have have suggestions for a good sounding one?. $100 Max.

K I think you'd need to use the tvs optical out to an optical splitter, one split to the SJ9, a second split to an optical dac

either something like this(no decoder)
https://www.amazon.com/PROZOR-Digita...0674941&sr=8-5

or like this(decoder)
https://www.amazon.com/Digital-Conve...0674961&sr=8-9

maybe better to go with the second one just in case some content is encoded only.

splitter:
https://www.amazon.com/LiNKFOR-Tosli...0675449&sr=8-8

2x rca to 3.5mm cable:

Did you catch those weasel words earlier, the part about "compatible LG home audio products" for bluetooth usage? Those words were copied from their Aussie site, and that's the part that had me skeptically confused; does LG have the ability to limit an LG tv bluetooth to only work with LG bluetooth headphones and LG bluetooth soundbars? (I don't know, but that's the kinda the inference...)

LG's U.S. C7P product page was worse than the Aussie site, nary a word re Bluetooth. For comparison my Sony's manual tells me it has Bluetooth version 4.1 with supported codecs SBC, AAC, LDAC.

Sony and Sennheiser have been making wireless TV/HT headphones for years now. One pattern I've noticed is: they use/used 900Mhz and 2.4Ghz and 5Ghz, but they NEVER use bluetooth, because of its inherent latency.


Somewhere along the way, Qualcomm developed the aptx low latency bluetooth codec. (Avantree has neat demo which anybody can replicate that shows off the efficacy of aptxLL versus other codecs->
)


OK i'm sold, I want aptxLL supporting headphones! Thing is, the transmitting source also needs to support aptxLL. My source doesn't support aptxLL, so I would need to buy a aptxLL supporting transmitter.

...And lately I've found out that its slim pickings when it comes to aptxLL supporting transmitters. Dolby and DTS to boot? Fuhgeddaboutit!

So all that is kinda why I don't have a BT recommendation, with me being stuck on aptxLL.

But one thing, I might suggest, if you can't get any love from LG customer support (Do I have aptxLL? Am I restricted to LG-branded kit?), is go to Best Buy and purchase a pair of cheapo BT headphones (I got beaters for ~$17), see if they pair-and-connect with your C7P tv, and -- if they do -- determine if you give a rat's behind about the lip sync issue.

As for traditional, non-Bluetooth TV/HT headphones system, I can offer a default recommendation:

Two years I recommended and hooked up Sony HW700DS wireless headphones for relatives. (They love 'em) IMO they really are the current TV/HT king of the hill (I don't count Realizer or PC-requiring solutions), but are long-in-the-tooth -- see the question I posed here https://www.avsforum.com/forum/90-re...l#post58564112 and Worf's response.

These (the Japan model; steer clear the UK model) will support multiple headsets and you can make work simultaneously with your sound system. At the time in 2014, Sony opened up the wallet and bought all the keys from Dolby Labs and DTS, Inc.

But I would recommend anybody wait and see what announcements early January 2020 brings, because I think its high time somebody (well, probably just Sony...everybody else seems to care even less) updates them to 2020 era buzzword compliancy with ATMOS and DTS:X and bigger HDMI plumbing.

Those prices are reasonable. I was looking on the Sennheiser website and it says "The alternate way to connect to a digital output is to use a digital to analog decoder which will take the digital signal and change it into an analog signal. When using a digital to analog decoder any analog headphones have the ability to be connected to a digital output. NOTE: The Digital to Analog Decoder we recommend is the OREI DA 34 as it is a good quality component that not too expensive but does not compromise the audio quality."

"The number of wireless headphones (regardless of manufacturer) that will connect directly to a optical audio output is actually quite limited. The Sennheiser RS 175, RS 185 and RS 195 Wireless Headphones have the ability to connect directly to a digital optical output that is outputting a PCM signal."


The RS160 i don't think connects directly. Which of those 2 links of the DAC's do you recommend for this headphone and do i need to buy extra optical cables or other accessories?. The OREI DA 34 is what Sennheiser recommends and is similar to the product you showed me but OREI DA 34 more expensive.

Here is the link to Sennheiser RS160 scroll down to FAQ https://en-us.sennheiser.com/wireles...digital-rs-160

The Orei is fine, it has a decoder and a 3.5mm output, so you can connect directly to the rs160s base. Youll need one optical cable from the tv to the orei. If you want to use the headphones and the soundbar at the same time, then youll need the optical splitter i linked, as I dont think the tv can output to multiple outputs at the same time.
