Question about Sony MDR-RF970RK Headphones

1 Answer

Headphones has red light

Have plugged in our headphones to the same jack as the others and we can't get past the charging stage. The red light never turns green and no sound comes from the headphones. Have we connected it incorrectly? We are plugging them into a Yamaha Receiver. HELP.

    It use to indicated it was engaged by soundin off up the scale four notes. Now when I try to connect it is those same up the scale four note the pause it sounds to down notes? IPad is not connecting with Sylvania SBT214-White Bluetooth Stereo Headphones, and it thinks it is not within range. Have I over charged the headphone?

Hello, I believe I just figured out the solution to this problem. I was experiencing the same thing, and as I was just showing my friend the problem I noticed that the green light came on after I turned on the music on my computer.

So, after removing the headphones from the base, the green light will come on only if there is sound playing from the computer (It takes a few seconds to turn on). It seems like they should have mentioned this somewhere in the manual...

Sennheiser RS 120 headphones won't work, only hear static

Set up the transmitter. Wireless headphones rely on a transmitter that sends audio via infrared or radio waves to your headset. Use the digital audio output (coaxial or optical), RCA outputs (red and white) or headphone jack on your TV to connect the transmitter. The connection will depend upon which outputs are available on your TV and/or the transmitter.
Use an RCA-to-headphone adapter. If you don't have a headphone jack on your TV and the transmitter includes only a headphone connection, connect an RCA-to-female headphone connector. This will allow you to plug the wireless transmitter into the female headphone end and then hook the RCA ends into your television's audio outputs. You may also need a 3.5 mm (mini jack)-to-1/4-inch adapter if the headphone plug on the transmitter doesn't match the television jack.
Read more :
Set the transmitter on top of, or next to, the television. For infrared transmitters, you'll need a direct path between the headphones and the transmitter. Placing the transmitter on or near the TV will allow you to take advantage of the clear path you already have.
Plug in the transmitter and turn it on. Charge the headphones if necessary.
Turn on the headphones. Adjust the volume and settings and you're ready to watch TV.

Why do I only hear static

Hi Cathy.. it sounds like you might be connected to the wrong jacks instead of the output that the headphones need.

Most high quality stereo headphones have a single 1/4" stereo plug that would readily plug into a 1/4" jack on the front of the stereo labeled "PHONES" or HEADPHONES".

Many lower quality "computer headphones" or headsets have two 1/8" plugs. One is often black or red and is for an included microphone that may be a boom type (shown below) connected to one of the speakers or an "in-line" type built into the cord itself. The headphone speakers in the headset get their signal from the other plug - which is usually green; but could be any color really. There should be 3 metal parts on the stereo headphone plug. The tip, the middle ring and the bottom ring. Many times the mic is mono (not stereo) and only has only a tip and a bottom ring on the plug. You can see stereo headphone and microphone plugs he picture below:

Computer Headphones or "Headset" with mic and phone plugs.

Your Yamaha stereo will probably NOT have 1/8" jacks to directly plug the headphone into. You can buy an adapter that you would plug your headphones into and then plug the adapter into the 1/4" jack on the stereo. One is pictured below:

Front and rear views of a "1/4" to 1/8" Stereo Adapter Plug" The front plugs into the stereo and the the smaller 1/8" headphones plug into the rear.

I hope this helps & good luck!

I am attempting to use my sennheiser rs 110 headphones with my lcd-led tv. the componet jacks coming out of the transmitter are red and black. All my componets on the tv are red and white. so when i plug...

What are you plugging your 2 RCA connectors (from the headphones) into on the television?
You are correct, usually:
White = Left Red = Right

In this case
Black = Left Red = Right
Not sure....guess some manufacturers need to be different...
Back to the issue,
You to need to connect the Black to White and Red to Red to the TV BUT you need to make sure you are connecting to an OUTPUT and not to an INPUT on the TV. Most newer TV's do have an "audio out RCA jacks" on the TV but not all. It should be labeled at the connector if it is an output, or just another input. You can always consult the TV manual to be sure.

Few things you can do to test
  • Does your TV have a "headphone jack", use the adapter (2 RCA female - 3.5mm connector) to plug into the headphone jack and see if there is sound
  • Connect the Black and Red RCAs from the headphones directly to the another output, like a DVD player, CD Player etc....

I hope this helps,

One earbud stops working

-Have you try this headphone plug to other device to find out it does the same thing or not.
-If it work with other then that meant your device's jack is worn out.

Good luck

Using headphones

You can get a set of speakers that has a headphone jack on front (it will shut off the speakers when headphones are in) or you can unplug the speakers and plug in the head phones. Some PCs have a red and green jack in front - plug in headphones to the green, you should have the speakers shut off till you unplug. All else fails they make a headphone/mic extender that sits like a hockey puck on the desk, has cables to the mic and speaker jacks on back of the PC and on the puck part has a jack for speakers, mic and headphone - some switched manually by you, some switch when the headphones plug in. If you had posted the model I could see if your machine has front red and green jacks.

Sentry HO900 headphones

The H0900 should come with a mini-plug adapter. The headphone jack in my TV was deeply inset, so I kinda reversed it. The adapter plugs into the transmitter, then the Red/White plugs, into that, then the long end of the cord into the TV.

Works fine for me. My problem will be posted seperately.
