How to Fix Sennheiser PXC 550 Charging Problems


If your Sennheiser headphones are not charging, it could be due to a number of factors. Here are a few troubleshooting tips to help you get your headphones back up and running:

When experiencing problems charging your Sennheiser PXC 550 headphones, an important first step involves a thorough check of both the charger and the charging cable. These components form the basis of a successful charging process and warrant close attention.

Check the charger and charging cable


Start by making sure you’re using the original charger that came with the headphones or an approved Sennheiser replacement. Using incompatible chargers with different voltage and amperage specifications can compromise charging or cause potential damage.

Also, check the charging cable for any visible damage, such as frayed wires, bent connectors, or compromised insulation. Even seemingly minor damage can significantly prevent proper charging functionality, in which case, it is advisable to replace the cable with a new one.

Remember to securely secure the cable to both the headphones and the charger, checking for any loose connections that could hinder efficient charging.

Additionally, inspect the charging port on the headphones, as the presence of debris, dust or foreign particles may impede the charging process. Using a can of compressed air or a light brush, carefully clean the port to avoid damage.

Perform a hard reset


A hard reset involves the deliberate action of resetting the headphones’ internal electronics, often fixing minor glitches that may be causing the charging problem.

  • Ensure disconnection: Unplug the charging cable from both the headphones and the power source to ensure complete disconnection.
  • Press and hold buttons: Find the power and volume buttons on your headphones. Depending on the model, specific buttons may vary. Press and hold the required combination of buttons simultaneously. Typically, this involves holding down the Power button and the Volume button.
  • Hold for duration: Press and hold the buttons for about 15 to 20 seconds. During this period, you will see various indicators such as lights blinking or the device powering off and then on.
  • Release Buttons: After the elapsed time, release the buttons. The headphones should now reset.
