JVC HARX900 full-size headphones

These wired over-ear headphones use a 6.3 mm gold-plated connector and a 50 mm neodymium driver to deliver stereo sound. They are built for listeners who want a long 11.48 ft cable and a wide 7 Hz to 26 kHz frequency response. The 64 ohm impedance and 106 dB sensitivity suit home audio equipment.

Wired 6.3 mm connector limits mobility

The fixed 11.48 ft cable ties the listener to the source device and the large 6.3 mm plug requires a matching jack or adapter. There is no wireless option, no inline remote and no microphone for calls. The open-back design leaks sound, so they are not suited for noisy environments or private listening in shared spaces.

64 ohm impedance decides amplifier pairing

At 64 ohms the headphones need a source that can drive higher-impedance loads cleanly; portable players with low-voltage outputs may not reach adequate volume. Buyers who only have a smartphone or laptop without a dedicated headphone amplifier should check compatibility before purchasing.

Questions about this item

Which impedance or driver-size version of the HARX900 should I choose?

The HARX900 is offered in a single configuration with a 50mm neodymium driver and a 64-ohm impedance, so there are no alternative versions to select.

What does the 7Hz-26kHz frequency response mean when I plug these into my amplifier?

The 7Hz-26kHz range indicates the headphones can reproduce deep bass down to 7Hz and treble up to 26kHz, covering the full audible spectrum and beyond when driven by a suitable source.

How does the 6.3mm gold-plated connector affect what I can plug these into?

The 6.3mm gold-plated plug fits professional audio equipment and dedicated headphone amplifiers directly; a separate adapter is required for devices with only smaller sockets.
