Question about JVC Audio Players & Recorders

1 Answer

My newly bought JVC Wireless Headphones (model: HA-S20BT) do not want to charge when connected to a USB port or 5V adapter. Any suggestions would be appreciated.

I recently bought JVC Wireless Headphones (model: HA-S20BT). I could charge the headphones one time after purchasing it. After the battery ran flat I tried to charge it by connecting it to a USB port as well as an adapter. None of these are working and the red charging light is not going on per the instructions.

SOURCE: Setup Bluetooth Wireless headphones

Each brand has it's own peculiarities and you did not specify the brand. I would suggest turning off the headphones, resetting the transmitter (turn off and on again for separate devices) and then pressing and holding the 'on' switch for 15 seconds or so. You may see (in some models) a light start to blink blue then red and back. This should indicate that the receiver (headphone) is trying to find a transmitter to pair with. Hope this helps.

SOURCE: Headphones has red light

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...

They need a minimum level of signal to switch on the transmitter.
Verify if it works on yet another system.
Make sure you have the right output on your Samsung.
Try to increase the output level of your Samsung...(up the volume, but it may be a fixed output..)

The following procedure will re-establish the communication link between the Headphones and the Wireless adapter, this is called "pairing". Before you start please make sure both the headphones and the wireless adapter are fully charged and turned off.
Note: The headphones and the wireless adapter come pre-paired from the factory.
1. Press and hold the power button on the headphones. See Figure 1.

Figure 1

2. Continue to hold the button down until the LED starts flashing red/blue in an alternating pattern. Release the button when the LED starts flashing red/blue. See Figure 2.

3. Once the headphones LED is flashing red/blue, press and hold the power button on the wireless adapter. See Figure 3.

Figure 3
4. Hold down the button until the LED starts flashing red/blue in an alternating patter. The LED will blink blue, then turn off for a few seconds then blink red/blue. Release the button when the LED starts flashing red/blue. See Figure 4.

Figure 4
5. Once both the headphones LED and the adapter LED is blinking red/blue, press the volume up button once on the headphones. See Figure 5.
headphone-volumeup.jpg
Figure 5
Once the headphones is paired with the adapter, the LED on the headphones will blink blue once every two seconds. See Figure 6.
headphone-flash2.gif
Figure 6
When the adapter is paired the LED will be solid blue. See Figure 7.
receiversolid.jpg
Figure 7
The adapter may continue to blink red/blue for a few seconds even after the headphones LED starting blinking blue. This is normal; the adapter may take a few additional seconds before the LED turn solid blue.
Once the headphones and the adapter are paired, it is not necessary to pair them again even if the batteries on both units are completely drained.
Additional Note: Repeated pairing will not improve the sound quality or give the headphones and the adapter a cleaner connection.

Hi there!
OK I know it is little late to response but if someone will google it, might find the solution, they are still selling it though. I just got my set as a xmas present so here is the way it works..
First plug the batteries into the headset, there is gonna be small power in it, however you have to charge it. So connect the small charging cable into the base unit and the headset and make sure the switch on the head set is off. Green LED light will appear on the base unit. Let it charge for 16 hours. After is charged you can unplug the small charging cable.
OK now how it works.
The base unit needs to be always plugged-in to the electricity supply. Connect the audio connector from the base to the e.g. TV, PC, DVD player, mp3 player... After you plug-in the audio connector red LED light will automatically light on the base unit.
There is is two channels what you can use, that's in case if you have two of the same wireless sets. So if on the base is set to # 1 the headset needs to be also on # 1. Then if you have second headset choose channel # 2 on the base and also on the headset # 2, so they are not crossing each other.
Now press switch on button on the headset and red LED light will appear. There is nothing wrong with the red light. That's just the way it is..
OK that's it. Adjust the volume on the headset and you should be able to listen to the music.. :)

Hope it was helpful.

Charging problem?


The battery in the headphones is most likely not taking a charge anymore and will need to be replaced with an equal value rechargeable battery

Straight up- I do not understand myself nor know how to fix your headphones retractable cord. I however instead of skipping your question chose to give you some informational insight or clues on how to gather your answer.

I have seen that no one has posted to help you as of yet so I figured giving some information on how to find your answer is best rather than to ignore your question. Here are some things that you could type into search engines which will directly take you to either or both reading and video tutorials, which will tell you how to take the headphones apart to fix their cord and or will actually show you the steps to take to fix them.

I am assuming that your question wasn't answered either because no one knew how to fix them or that because they don't know how to fix them they assumed not to make any suggestions since maybe they would had felt bad if they were to tell you to do something in which could ruin the headphones. Here is the following suggestions to go by to fix your head phones: I hope this helps:)

A. Search Engine; GOOGLE.. Search " JVC Ha-nc100 headphones needs fixing to retractable cord".
B. BING SEARCH ENGINE: " WATCH MOVIE ON HOW TO REPAIR JVC HA-NC100 HEADPHONES RETRACTABLE CORD."

HOWEVER IF NONE OF THIS WORKS FOR YOU OR IF YOU PREFER FOR MY ASSISTANCE TO GET YOU THE LINKS MYSELF SO THAT ALL YOU WOULD HAVE TO DO IS TO CLICK ON THE BLUE LINKS WHICH WILL DIRECTLY TAKE YOU TO THE SITES THEN PLEASE LET ME KNOW AND I WILL FURTHER HELP YOU.

I THINK THAT THERE IS AN WAY TO COMMUNICATE WITH ME AND OR TO REPLY BACK TO ME. I HOPE THESE SUGGESTIONS HELP. JUST DIDN'T WANT TO LEAVE YOU ALL ON YOUR OWN TRYING TO FIX YOUR ISSUE WITH YOUR HEADPHONES:) HAVE A GOOD DAY/NIGHT.

Jvc headphones retractable cord


The JVC HA-NC250s are a new version of their previous model 100, and JVC claims that they will cancel up to 85% of ambient noise, coupled with better sound. In this case, JVC claims up to 16.5 db reduction at 150 kHz. These on-the-ear headphones are very lightweight at 5.3 ounces and are extremely comfortable. The head band has a reasonable amount of sliding expansion for bigger heads, and the oblong ear pieces themselves rotate and fold flat for storage. JVC uses memory foam on the earpieces, as well as double housing, for extra noise isolation. The earpieces have 40 mm neodymium drivers, which are the same size and type that the Creative Aurvanas offer.The JVC HA-NC250 noise canceling headphones. Note the ear-cushion instruction tab that explains how to replace the hidden battery.

The NC250s come in a semi-rigid black case with a dual airline-plug adapter, a mini-to-RCA phono plug adapter and a 4' detachable headphone cord. JVC includes one AAA battery, which should last approximately 50 hours. A simple sliding switch on the right side turns the noise reduction on along with a small red LED. Learning how to add the battery to the headphones required that I study JVC's user manual. The process involves having to remove the earpiece covering to get to the battery compartment, which isn't at all obvious.

Bought a set of wireless headphones but they only have a small headphone jack (size of Ipod headphones) to connect the transmitter to dvd player. How do I connect?


Get an adapter to convert whatever stereo plug you have to whatever stereo jack you want it to mate with. I imagine the wireless headphone documentation discusses that.

I have a wireless jvc headphones, the item is 110 volts but was accidentally plugged in to a 220 volts socket. can this still be repaired? thank you.


It no doubt can be repaired, but chances are it's going to be pricey. The power input circuit will be blown for sure, and probably most everything ahead of it, since voltage came in on the ground side also (a 220V line is just 2 120 lines, and it's usually more like 228-240). You would be better off trying to get one off ebay, or on sale, than to repair this one. Sorry to relay the bad news. Of course, the headphones will still be good, that's the good news.

i have seen issues with wireless USB adapters. Can you try another USB port on the computer? Also delete the adapter and let it br reinstalled. If this does not help, I would suggest returning it and getting a Linksys adapeter.

Chargind psp


If it’s the 2000 series (PSP Slim), then yes. Connect your PSP system to an available USB port on your computer. Turn on your PSP, then under “Settings“, select “USB Connection”. Your PSP should connect to your computer and start charging. It may take awhile, but it will charge it all the way. Hold the display button (The button with the rectangular shape at the bottom of your PSP) until the screen goes black. This will speed up the charging process and is a good method of prolonging battery life when listening to music or other things.

If that doesn’t work, try looking for an adapter lying around your house that matches the volt numbers. The PSP takes 5V. Most portable CD players use 5V adapters and are usually the same size as needed for the PSP. I suggest using an adapter that matches the volt number and fits without trouble. If the orange light doesn’t come on or the PSP acts weird after charging, I’d stop using the adapter. Ask me any questions if you have any. ;)
