Step-by-Step DIY Guide to Replacing the Batteries in the Bose SoundSport Wireless Free Earbuds at Home

In this detailed DIY repair guide, we show you how to replace dead or dying batteries in the Bose SoundSport Wireless Free earbuds yourself. The repair process is identical for both earbuds. Follow each step carefully and use the accompanying images as a visual guide to complete the repair with confidence.

Step 1: Remove the Exterior Cover

1.1. Set your heat gun to 140°F (60°C) and 70 airflow, and apply heat to the earbud housing.

1.2. Once the earbud gets warm and the adhesive softens, insert a flathead screwdriver into the seam between the outer cover and the earbud housing, then gently work the tool around the perimeter until the cover separates.

1.3. Remove any old adhesive from the earbud housing with precision tweezers. This ensures a proper seal during reassembly.

Step 2: Extract the Dead or Failing Battery

2.1. Disconnect the ribbon cable connecting the button to the main board with a flathead screwdriver.

2.2. Lift the PCB from the earbud housing with a flathead screwdriver to reveal the soldered connections for the battery. Be careful not to damage the battery terminal as you pry it out.

2.3. Apply heat to the battery to soften the adhesive securing it to the PCB. Move the heat gun around to avoid heating a single area, as it may damage the battery, wires, or the circuit board.

2.4. Apply soldering flux to the battery terminals, then desolder them from the PCB.

2.5. Hold the battery and PCB securely with your fingers, then gently pull them apart. If needed, use a flathead screwdriver to carefully pry them apart without damaging either component.

2.6. Desolder the other wire connected to the battery.

Step 3: Install a New Battery

Grab a new battery, align the terminals with the PCB, then solder the wires to form a secure connection.

Step 4: Reassemble the Bose SoundSport Wireless Free Earbuds

4.1. Place the PCB back into the earbud housing, then tuck the battery wires safely into the grooves. Make sure the battery terminals and wires are perfectly aligned to ensure a secure connection.

4.2. Reconnect the power button ribbon cable to the PCB.

4.3. Apply a thin line of Joe’s cold press glue along the perimeter of the earbud housing.

4.4. Align both parts of the housing and press down for the adhesive to cure.

4.5. Use a cling wrap or rubber band to apply constant pressure on the earbuds while the adhesive cures for the next 24 hours.
