Frequently Asked Questions

• Is it possible to replace the battery in the earbuds?
  While Bluetooth headset batteries can be replaced, most wireless earbuds cannot. Although battery change is possible in some earbuds, it is not only a do-it-yourself activity, but it is also rather complex.

• How long do the batteries in earphones last?

• Most Bluetooth earbuds can last for 4-6 hours on a single charge, whereas Bluetooth headsets can last for 6-12 hours. A decent quality Bluetooth headset from a premium brand can last 20-22 hours on average, and up to 30 hours if features like active noise cancellation are turned off (ANC).

• Are earbuds harmful to your ears?

  Yes, the higher the mAh rating, the longer the duration between charges. A battery’s larger mAh rating has no effect on electronic gadgets other than allowing for extended use.

• Should I keep my earbuds on all the time just in case?
  Lithium-ion batteries are used in almost all wireless earbuds, and they are engineered to stop charging once they are fully charged. Your earphones will be protected if you keep them in the case.

  The quick answer is that you should charge as needed. Earbuds can last 1.5 to 3 hours after being removed from the case, depending on the battery. The case can last up to 24 hours before needing to be recharged. As a result, you must charge your earbuds at least every 24 hours.

  The unit mAh stands for milliamp Hour and is used to measure (electric) power over time. It is widely used to determine a battery’s energy capacity.
