Dual Jet technology is precise pressure balancing across all frequencies. This technology allows us to match the air pressure in front of the driver, to the rear of the driver. As a result, we are able to release a build-up of pressure, or use it to maximise the front output of the earphone. Flares® PRO uses this technology to maximise the front output of the earphone. This reduces distortion levels and boosts overall volume enabling the driver to perform as efficiently as possible.
