Our take on the JBL Synchros E40BT Wireless Bluetooth Headphones with FM radio Mic

The JBL Synchros E40BT is an on-ear wireless headphone with 40 mm drivers, Bluetooth audio and a built-in FM radio and microphone. It folds flat for travel and runs on a rechargeable battery rated for many hours of listening. Its sound is bass-forward and lively, which suits pop, hip-hop and casual listening more than critical or studio work. Against newer on-ear Bluetooth models it lacks active noise cancellation and modern codecs, and owners note the on-ear clamp and modest isolation.
