JBL Tune 520BT

The new model delivers up to 57 hours of wireless music playback, a significant improvement over the previous model’s maximum of approximately 40 hours. No need to worry about running out of charge frequently, even when commuting to and from work or school, taking online classes, or taking long calls.
The new model also supports a quick charge function that enables 3 hours of continuous use from a 5-minute charge, so you can use it even in unexpected situations, such as when you forget to recharge the battery in time.
This model also supports a volume limiter function that can be set via the app to prevent the volume from exceeding 85dB, allowing users to adjust the volume so as not to strain their hearing even after long periods of use.
