The JBL Synchros E50BT could probably explode your head if you turn them at full blast. Your physician will definitely advice against that. Well, you can still enjoy the PureBass Performance at moderate levels and let it envelop your ears with a clear and precise sound. Also, your ears will feel comfortable thanks to the ergonomic headband and 3-D hinges. They comes with Bluetooth® for wireless connectivity so you can walk around your home freely and still enjoy your favorite tunes with a reduced passive noise.
