Earbuds come with a charging cable. It is a specialized cable that will only work with these earbuds. The earbuds snap into the charger which has a USB connector that you plug into your computer and/or USB charger. Takes an hour or so to charge them. Charge seems to last about 6 hours. In one of the reviews of this product, the reviewer noted that the charger is unique so you need to be careful not to lose it. This reviewer noted that if you do lose it the only way to charge the earbuds is to contact Jaybird and buy a new one from them. I went on the Jaybird website and found that a replacement charger for the Tarah earbuds is $5.99 plus shipping.
