Only the right side works

Hi friend, 

Thanks for choosing EarFun. Sorry for the inconvenience caused.

Could you please send us your order number to check and describe the specific issue of the malfunctioning earbud so that we can provide the corresponding suggestions to you?

The earbuds can't turn on and charge? The earbuds can connect to your device but there is no sound out of it? 

Please email our customer service team via service@myearfun.com or submit the warranty ticket on our official website: https://www.myearfun.com/process-warranty so we can respond to you ASAP. EarFun provides an 18-month warranty for every product. Your satisfaction is always greatly important to us.

Sincerely,

EarFun Customer Service Team
