The August EP650B are over-ear wireless headphones connecting via Bluetooth 4.2 with aptX Low Latency support for reduced audio delay, making them suitable for video and gaming use as well as music. NFC on the left earcup allows one-tap pairing with compatible devices. Multi-point technology allows connection to two Bluetooth sources simultaneously, so switching between a phone and a laptop requires no manual re-pairing.

A built-in rechargeable 3.7V/220mAh lithium-ion battery provides over 15 hours of playback per charge, with a standby time of 30 days. For non-Bluetooth sources, a 3.5mm audio cable is included, and the headphones can also be connected via USB. The ear cushions are 12mm thick with a padded headband, and an integrated remote on the earcup controls track navigation and calls.
