2.5 mm to 4.4 mm balanced adapter

This short adapter cable converts a 2.5 mm balanced male plug into a 4.4 mm balanced female socket so you can use 4.4 mm terminated earphones with players that only offer a 2.5 mm balanced output. It is aimed at portable-audio enthusiasts who want a simple, high-purity connection without carrying a bulky dongle. The 5.1 inch length keeps the signal path short and tidy for pocket or bag use.

Thermals noise and power draw

As a passive copper and silver conductor the cable generates no heat, emits no noise and draws no power of its own. The four cores each contain 19 strands mixing single-crystal copper and single-crystal silver, terminated with gold-plated plugs to maintain low contact resistance. Normal use is limited to the output capability of the source device and the sensitivity of the connected earphones.

Bundled accessories and software

The package includes only the single 2.5 mm male to 4.4 mm female upgrade adapter cable; no headphones, pouches or software are supplied. The manufacturer highlights low-frequency control, wide sound field, natural tone and high analytical detail as the sonic character of the cable. A free replacement is offered if the cable stops working within six months.

Questions about this item

How do I connect the 2.5 mm male plug to my player and the 4.4 mm female socket to my headphones without reversing them?

Insert the 2.5 mm male end into the balanced output of your audio player, then plug the 4.4 mm male connector of your headphone cable into the 4.4 mm female socket on the adapter; the gold-plated plugs only fit one way.

Will the four cores with 19 strands each of mixed OCC copper and silver need any cleaning or re-termination over time?

The gold-plated 2.5 mm and 4.4 mm connectors resist oxidation, so no routine cleaning or re-termination is required under normal indoor use.

At what point does the 5.1 inch length become a limitation during extended listening sessions?

The short 5.1 inch cable keeps the adapter close to the player, so strain on the 2.5 mm jack is minimal; the practical limit is the reach between your player and headphones.
