Replacement dual 2.5mm cable for HIFIMAN HE400i and HE560 with a stretchable 6-16ft coiled extension
- lost or damaged original headphone cable
- need for longer reach from headphones to amplifier
- cable clutter on the desk
- connector mismatch with 1/4-inch amplifier outputs
Reach your amp across the desk with a cable that fits
Your HE400i or HE560 cable is frayed, lost, or too short for the amp. This dual 2.5mm replacement stretches from 6ft to 16ft and keeps the desk clear.
Dual 2.5mm plugs, marked left and right

Dual 2.5mm plugs, marked L and R
Each headphone cup takes its own 2.5mm TRS plug. The L and R markings show which plug goes to which cup, so there is no guessing when you swap cables late at night.

Coiled reach, up to 16 feet
The coiled PVC extension stretches from 6ft to 16ft, so the amp can sit on a shelf or credenza instead of crowding your keyboard. When the amp sits close, the coil takes up the slack. Run the leads through a desk wire organizer to keep the run tidy.
Braided leads, reinforced strain relief
Braided nylon sleeving covers the headphone-side leads, and reinforced strain relief sits at each connector, where cables usually fail first. The gold-plated 3.5mm plug on the amp end keeps the connection clean over time.

The cable that let you down

The cable that let you down
The original cable usually gives out at the connector, after months of plugging and unplugging. Then the headphones are either out of service or stretched across the desk to reach an amp that sits too far away. Both problems start at the same weak point.
Reach the amp, keep the desk clear
A dual 2.5mm replacement with a coiled extension closes both gaps. The coil reaches up to 16ft for the amp, the 6.35mm screw-on adapter covers 1/4-inch outputs, and the desk stays clear for your keyboard and notes.

Questions and answers
Yes. The headphone end uses dual 2.5mm TRS plugs marked L and R, sized for the HE400i and HE560 cups. Match the markings and seat both plugs fully.
Only if your amp uses a 1/4-inch output. The 3.5mm amp plug connects directly to a 3.5mm jack. For a 6.35mm input, screw the included gold-plated adapter onto the plug.
The coil collapses back to a short run when the amp sits close, so the slack stays off your keyboard. Stretch it only as far as the amp needs.
Yes. It replaces a lost, cracked, or frayed headphone cable, and it gives the headphones a longer run to the amp than the original.
The amp end has a gold-plated 3.5mm plug, the leads are braided nylon, and each connector has reinforced strain relief. Those are the parts that wear first on a cable, so they get the attention.
A spare costs far less than replacing the headphones, and it lets you keep the amp in its spot while the main cable is repaired or cleaned. Most owners who buy one keep it in a drawer for the day the first one fails.
