Today while running (without navigation!) my headphones worked perfectly for the first time since I bought my Enduro 3 shortly after they were released in 2024. I enjoyed 70 minutes of music without any dropouts or crackling!
What had I done? I didn't change anything! Nothing at all!
Just yesterday I did a similar workout and had to switch the device from one wrist to the other several times, still experiencing pops and clicks. Apparently GPS, especially with navigation turned on, often interferes with the Bluetooth connection, which means you have to bring the watch within 30 cm of the headphones to ensure a connection, often of poor quality.
In my opinion, it's ridiculous that Garmin has no luck or doesn't even try to make the headphones work for everyone and in every case.
