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® JET 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.
