That may be the case if your aircraft has wiring issues. While the cabin of a noisy piston-powered aircraft is perhaps the worst environment for listening to your favorite tunes, it’s often the aircraft wiring that makes the sound quality laughable by even the lowest standards. Bluetooth audio panels help because eliminating the patch cable that connects your music player to a music input jack can also eliminate noise. But they aren’t the cure-all for subpar music quality. Even with a flagship Bluetooth audio panel like Garmin’s GMA350C and PS Engineering’s PM8000-series, music playback quality will only be as good as the wiring between the audio panel and headset jacks, the health of the ignition system, charging system, grounds and a slew of other variables.
