Acoustic Research AW772 Wireless Headphones

Sometimes when I place the head set in the cradle the green light goes out and sometimes it stays on even with the TV off.
With the head set in the cradle is the green light supposed to be on or off.

Also, where can I get a set of instructions for these wireless headphones?

Thanks so much.

    I'm having the same problem. When I place the headset in the cradle, sometimes the green light stays on and some times it goes off. When the green light turns off, the red charging indicator light is supposed to light up but it does not.

    On Acoustic Research AW772 Wireless headphones the left earpiece got pulled off and the wires are intact but disconnected. How can I find out where I solder them back in?

    Phone does not seem to be charging. The red charge light is always on. The green button on the base station is always on. Shouldn't the red charge light turn green when it is charged?

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.

NEED INSTRUCTIONS FOR HOOKING UP WIRELESS HEADPHONES FOR VIZIO TV


From the manual:

1. Plug the stereo audio cable into the headphone jack of your audio
source (e.g., stereo, TV, CD player, DVD, etc.). If your audio source
has two RCA output jacks instead of a headphone jack, use the
supplied Y cable to connect your headphones to the two (red and
white) RCA jacks.
2. Connect the other end of the stereo audio cable to the AUDIO IN
socket at the back of the recharging cradle/transmitter.
3. Connect the AC/DC main power adapter to the DC IN power
supply socket at the back of the recharging cradle/transmitter. Then,
connect the adapter to an electrical outlet.
Important: This power unit is intended to be correctly oriented in a
vertical or floor mount position.

I hope this one is not kept too long idle and without charge. Check on the points and the connections and try again maybe put it on for sometime to enable time for triggering any low voltage stage from where it has to recoup. Hope this will help

Operating manual


After connecting all cables.... try channel 1 at the receiver... then move tuner up and down until the green light on the left headphone lights up and you can hear whatever you are listening to. If channel 1 doesnt work, try 2 and 3...... mine is set on CH3.

Good luck
