Bluetooth Headphones Cut Out During Podcasts Only When Charging

I recently got a pair of Bluetooth headphones that are great for my daily podcasts during my commute. However, I noticed a weird issue: whenever I plug them in to charge while listening, the audio cuts out every 10-15 seconds. It doesn’t happen if I’m just using them unplugged with decent battery left, and the connection to my phone stays strong when not charging. I’ve tried resetting the headphones and updating their firmware, and I tested them with two different phones (an Android and an iPhone), but the problem persists. The charging cable and port seem fine, no loose connections or visible damage. It’s frustrating because I like to top up the battery mid-trip without losing my podcast stream. Has anyone seen Bluetooth audio cut out like this only during charging? Could it be interference or a hardware defect? What are some good troubleshooting steps or fixes to try before considering a warranty claim?
