Rated 5 out of 5 by from Cost every coin i spent I use them for a year or so. They recharging fast and survive long, not even noticed battery getting weaker. Great sound, nice range and signal stability with my phone. Comfy and stylish. Whats bad? Dunno, problems with windows 7, but it is software problem, not headphones. Nice piece, JBL

The headphones don't charge, the led remains dark when I connect it to the wall charger or computer. I also couldn't find any hint anywhere what the led is supposed to show when connected to the power source. Tried two dfferent chargers and the computer. 

Asked by: Uiglr
What you are experiencing is not normal. The E50BT should display a solid red light on the BT symbol when charging. When it is fully charged, it displays a solid white light. Try using a different charger at an alternate power source and let it charge. I noticed that you are in Germany. If you are still having issues, please contact the store where you purchased it from or contact your local JBL Customer Service for technical support, thank you!

I recently purchased the E50BT headphones and when I plug them to my phone, I only hear out of one side (left). T.he same happened wireless. Now this was before I charged them for the first time. Is this normal? And how can I get the owners manual.

Asked by: bkhoward1
Please try to pair the E50BT with a different phone. Also check if your device has an EQ setting to balance the audio. For the Owner's Manual, or if you are still experiencing issues, please submit a case at www.jbl.com/support-contact.html and our Customer Service team will be glad to assist you.
