SOURCE: I need ni-cad battery specifications for Acoustic

The AR AW721 headphones require 3 AAA NiMH batteries, not Ni-Cad. The original batteries are 1.2 volt, 550 mAh. I replaced mine with Energizer 850 mAh AAA batteries, which work well and actually last longer per charge than the originals.

How do I turn on my headphones?


Those are Bluetooth headphones. You have to pair and connect them to a Bluetooth-enabled device, such as a cellphone or tablet, as per the instruction manual that came with the headphones (where you will also find out about the buttons on the headphones, including the power button). And don't forget to charge them before using them.

Can you confirm if you are able to put the BTH220 headphones in pairing mode. Please try the following steps and see if works:
  1. Make sure that the headphones are fully charged.
  2. Switch off the headphones.
  3. Put the headphones in pairing mode by pressing the MFB button (center) for 7-10 secs till you see the red and blue LED blinking alternatively. Please do not leave the button as soon as blue LED appears.
  4. Follow the operating instruction of your Bluetooth device to start the pairing process.

Headphone for DVD on 2006 Chrysler Town and Country


Just found this and it worked! Hope it does for you as well:
There should be a button on the DVD remote control with a headphone symbol on it. Make sure the headphones are turned on(red indicator on earpiece) and push the headphone button on remote. The headphones will only work in the back seats of the vehicle. Once you have audio to the headphones, you should be able to hit the AM/FM button on the radio and listen to the radio while back passengers use the headphones for video.

Hi, I buy a new Plantronics Backbeat 903, but right now it's unrecognizable by any movile, can you give some hints on how to fix that problem. I try with an LG P500 and Nokia 6110, no answer...


Delete the device from the phone, then re-pair the headphones with the phone. If you just turn on the headphones, the device cannot connect because the headphones store the information that you already deleted it on the phone. To pair again with the other device (like a computer, phone, etc) you need to turn off the headphones, then turn on the headphones but press the power/pair button and hold until the led flashes red and blue (like 10 sec after the led turn only blue) to put it in discovery mode. Then turn on your phone and follow the instructions for finding (discovering) your bluetooth headset.

Good luck from Headsets Direct!

Not enough sound from the headphones.


Every time you add another set of headphones it will cut the power sent to each headphone down as the power is shared between all the headphones being used. If you need it louder simply use less headphones as the unit does not have enough power to run all 3 at the volume you desire.

Tip of my headphones popped off in the headphone jack


The easiest way to get it out would be to use a couple of long sewing needles and put them in the jack on either side applying a little pressure (Not to much or you'll have broken needles in there too1) like chopsticks try and pull it out. Make sure you do this with the power off. If you want to salvage the headphones the connector will need replacing, they can be bought at most electronic stores. It's a 3.5mm headphone jack that your after. They can give you instructions for fitting at the shop, it varies depending on the connector.

Logitech Freepulse headphones won't turn on


There is a reset button on both the headphone and the transmitter. Try to reset them both before attempting to pair them again. Since the led won't turn on there is a possibility that the battery is not charging. Is the orange light working when the headphones are charging? It should be and then it should turn off when the battery is full.
