Could be a battery problem, ut is usually a problem with the charge cable or connector. Try a different charge cable, they are usually Micro USB connectors, and check if the power (MaH) Matches what your phone needs. Otherwise you might need to repair the port. Try this.

Whatdo i do if my skullcandy headphones dont charge?

Are these amplifing headphones or ? Most headphones use the devices power source to make the headphones work, they use very low voltage and various ohlms to make the earpieces vibrate and make sound. If they are not working try pushing the connection in all the way, or try another set of headphones to see if the problem is with the device. Sometimes we get defective headphones right out of the box, Skull Candy is usually very reliable and quality checked before shipping, but it can happen with all manufactures. Gool Luck.

If there is a battery in the earpiece; is it safe? There is some controversy about the safety of holding a cell phone to one's ear for extended periods; that's why I wanted an ear piece.

Yes it is perfectly safe. The easiest way to identify whether a bluetooth set is malfunctioning or unsafe is - HEAT. Normally batteries which are about to die or devices malfunctioning will heat up quickly when you charge it.

So unless you dont feel abnormal heat.. they are perfectly safe. Try to remove the BT earpiece when not needed. Your ear canal needs natural air flow. Blocking it with a prolonged use of a BT device could heat up the ear canal. That's where the problem starts! :-)

Lost manual need to charge my earpiece

Need more information...what earpiece are you using? Does it have the same charging port as your phone? Chances are your earpiece charges through a micro-usb port. If this is the case, you can easily find a new charger that is of size micro-usb (that is the same size as the charger of most new cellphones).

Lg ku990 heats up.... i dont know why but every time i charge my phone it always heats up

LG phones have this weakness of getting heated up while charging and even sometimes while on a call. Try to put charging on the power socket that has enough grounding
