Frequently criticized
Some users report needing to reset the headphones periodically, including one who needed to reset every couple of months and another whose long-working unit suddenly required a reset after years of use.
Frequently criticized
Users describe inconsistent or unclear indicator behavior during reset, such as needing to press the power button for the LED to turn red or having to hold three buttons until the LED turns greenish instead of following expected steps.
Strongly criticized
The manual claims 40 hours of listening time, but one user testing a new unit found real performance closer to 8 hours or less. This is a substantial shortfall from the marketed battery life.
Generally negative
One user notes that the JBL Headphones app is not compatible with the Tune 570BT on Android, leaving them without official companion app support and searching for alternatives.
