JVC HAFX5 Overview An inner-ear version of JVC's original Gumy, the black HA-FX5 Gumy Plus Earbuds are for people who prefer an inside-the-ear design over traditional earbuds. Its comfortable fit provides insulated noise isolation, while its 11mm Neodymium Driver Unit delivers a frequency response of 10 Hz to 20 kHz (which, it should be noted, fully encompasses the spectrum of human hearing). Additionally, its standard gold-plated plug is fully compatible with mobile phones and other devices.
