Introduction

Are your speakers having trouble producing sound? Is the sound muffled or non-existent? If yes, this replacement guide can help.

For the Audio-Tecnica ATH-M20xBT, speakers are a necessity. Speakers take electrical signals sent from the battery, and convert them into sound waves through electromagnetism. If the connection is faulty or not properly done, it can cause sound waves to move differently to your ear where a problem can be sensed.

Make sure to identify the problematic speaker before you start. To determine if replacement is necessary, view our troubleshooting pages:

Beware! This guide involves desoldering. Take care to avoid contact with hot solder, as it can cause burns or damage internal components. Ensure the device is powered off and fully disconnected from any power source before beginning work. The speakers are also held in by sticky adhesive easily weakened by heat.
