First thing is you need to have a signal going to the headphones for them to work.

If you are getting a signal the green light should be lit.

If only the red lamp is lit the headphones are not getting a signal.

If hooked into a television you should have them plugged into a Fixed Output not variable output..

If you only have a variable output then you must turn the speakers off on the television and then turn the volume up on the TV in order to send a signal to the headphones.

If you are using a amplifier make sure you are using the correct output. Tape Monitors generally will not work as this output is not amplified.

Lastly try using an rca to headphone adapter and plug them into a headphone jack.

Obviously your rechargeable battery isn't getting charged. It's probably a good battery as it recovers enough to run for 3 minutes after you try charging it. (all that's happening is the battery is allowed to rest and it recovers a little bit of it's capacity.)
As to why it's not getting charged, it could be the charger or the wiring in the headphones or the wiring in the base or a few other possibilities. You didn't give us a model number or any other details so we can't get any closer than that.

you might be better off increasing the pre amp gain before notching out frequencies. The area of hiss will be in the area of 5k to 8k which will harm the sound of your vocal recordings as that is also the area of clarity and intelligibility. Try the Triton Audio FetHead that will fix it for you. linkd is here:

They're very easy to open. You can pull the outer pads off by squeezing them at the bottom edge.
Inside, you can prize the speaker plate off the white plastic body with your fingers, and access the connectors if you need to.
The headphones all just clip back together.
Mine just stopped working in the right ear. I fixed them in about five minutes.

Search on internet for owners manual. There is usually a small set screw within mic to help with the gain/sensitivity.

Replace current speakers with speakers that use neodymium magnets.Audio quality and volume should improve drastically.

It is most likely just to let you know it has turned on.
