JBL Tune 510BT Wireless vs JBL Tune 520BT

The JBL Tune 520BT are the updated version of the JBL Tune 510BT. The Tune 520BT have a much longer battery life and support the brand's app for greater flexibility, including an equalizer. On the other hand, both headphones have many of the same features, like button controls, and are similarly lightweight with unstable on-ear fits. That said, the Tune 510BT have a better-sounding microphone. Otherwise, they're very alike.
