Why is My JBL Reflect Flow Not Charging?

A JBL Reflect Flow not charging problem is not unusual. Your device may stop charging or not charge at all due to: 

Dirty Earbuds

The JBL Reflect Flow comes with a charging box for recharging the earphones. The case has several metal pins that supply current to the earbuds during charging. If the metal contacts or earphones are dirty, they might not charge correctly.

Faulty or Incompatible Charging Cable

The earbuds use a USB-A to USB-C charging cable, which can break or become faulty over time. For this reason, consider checking the cable for damage. 

Try a different charging cable if you notice any defects on the original one. Most importantly, ensure it is compatible with the earphones for optimal charging performance. If using an AC adapter, confirm it meets your earphones’ power requirements.

Damaged Charging Port

If the charging port has some damage, e.g. bent pins, the charging case won’t receive adequate current, meaning your JBL Reflect Flow earphones might stop charging or fail to charge at all. 

In this case, you can use a tweezer to straighten the pins. If the damage is severe, you may have to replace the entire port.

Firmware Malfunction

The software in your JBL Reflect Flow earphones might develop temporary glitches and bugs. These firmware malfunctions can cause your earphones to behave strangely and not charge as expected.

You can fix software malfunctions by resetting your JBL earphones to factory defaults

A reset will clear cache issues and correct minor bugs. It will erase all custom settings, meaning you may have to set up your earbuds afresh.

Here is how to reset your JBL Reflect Flow wireless earphones:

  • Place the earbuds in the corresponding slots in the charging case.
  • Plug the charging case into a power source.
  • Press the button on the right earphone.
  • Maintain this position for 5 seconds.
  • Release the button when the LED light turns off and on.
Note: Ensure the earbuds have some charge before performing a reset.

Disconnected Power Source

Your JBL earphones might not charge because of a simple mistake. You might have accidentally disconnected the charging cable from the USB port or AC adapter.

A faulty socket or a loose connection can also cause your JBL Reflect Flow earphones not to charge. Ensure that the charging cable is firmly in place to resolve the issue. If the wall outlet is defective, try a different one.

Over-discharged Battery

Sometimes, your JBL Reflect Flow earphones only need time to activate. If you haven’t used your earbuds for a while, the battery might over-discharge, leading to charging issues later. A deeply discharged battery requires time to recharge the internal cells.

Place the earbuds in the corresponding slots in the charging case and then plug in the charger. Wait for the earphones to charge for about one hour and see if this makes a difference. If there’s no change, you can leave the earbuds to charge overnight. If that doesn’t work, consider replacing the battery.

Incorrect Earbud Placement

The JBL charging box has two slots for your earbuds and each bud has a corresponding slot in the case.

As such ensure each earbud is in the appropriate slot to recharge your JBL Reflect Flow. Placing the right bud in the left slot, for instance, will cause your JBL Reflect Flow not to charge. The earbuds must also have contact with the charging pins inside the case to charge.

Hardware Failure

The JBL Reflect Flow is renowned for its solid build quality and durable design. However, this does not mean your earbuds are indestructible. Hardware failure can cause your JBL Reflect Flow buds not to charge. 

Inspect the earphones for visible damage and contact JBL support for help. If you don’t notice any damage, the battery might be dead. 

JBL earbuds use rechargeable Lithium batteries which can only survive 300-500 charge cycles before requiring a replacement. Visit a JBL service center to get a battery replacement for your earbuds.
