Where do you charge the headphones up. - Sennheiser HDR 140 Consumer Headphones

This behavior can indicate an issue with the battery of your headphones, as it may not be able to hold a charge or may have other internal problems. It's also possible that there's a software issue or a problem with the connection between the battery and the headphones' components. Here are a few steps you can try to troubleshoot the issue:

1. Check the charging cable: Make sure the charging cable is in good condition and properly connected to the headphones and the charging source.
2. Clean the charging port: Dust and debris can accumulate in the charging port, which can prevent a proper connection. Use a soft-bristled brush or a toothpick to gently clean the port.
3. Try a different charging source: If the issue persists, try using a different charging cable or a different wall adapter to see if the issue is with the charging source.
4. Reset the headphones: If the previous steps didn't solve the issue, try resetting the headphones by removing the battery or holding down the power button for 10-15 seconds.

If none of these steps work, the issue may be with the battery or the headphones' components, and you may need to contact the manufacturer for repair or replacement.

If the bluetooth you are referring to is a bluetooth earbud, the batteries may be dead. You may need to buy a new earbud.

Kathleen, what do the user guide instructions list as the normal charging time? Is there a light that changes colour when the headphones are charged?

You haven't listed the make and exact model of headphones in your question. Please add these details.

If the red light is on for such a short period of time, it probably means that the headphones are charged. The red light will flash for a long time and then turn green only when you charge on the dock headphones that need charging. I suggest to try to use them without charging them and see if the headphones work.

Charge your headphones and while they are charging press the call button and the volume up button and you problem is solved. After that just let your headphones charge.

if these are older headphones it's likely that the batteries have gone bad or are defective, if this is a new unit, (aside from returning it for working one) it could still be the batteries, but the other likely issue is the charging unit is defective. you could test with a volt meter to see if it's getting juice. you could also have a short in the headphones somewhere.

It sounds like the wireless headphone battery isn't holding a charge anymore. You will have to contact the company for a replacement battery. In some cases (depending on the model), the unit will have to be shipped back to the company for the installation. If your headphones are under warranty, you shoudl receive a replacement battery free of charge.

you need to replcae the charging pin of your head phone, it is having loose connection............

Didyou try taking the battery out of the headphone and replacing it? This may act as a reset and allow charging. I'm assuming that these headphones are not brand new, and that you are lining up the arrow on the one side with the arrow on the charging base. This is the only way the inductive charging can occur. Good luck!
