Geekria Apollo 4.4mm Balanced Adapter

The Geekria Apollo adapter connects a 4.4mm balanced male plug to a 2.5mm balanced female socket. It lets owners of compatible Sony, Lotoo, HIFIMAN, FiiO, Cayin and iBasso digital audio players use headphones terminated with a 2.5mm balanced connector. Gold-plated contacts and a copper body aim to preserve signal integrity in portable setups. The compact barrel measures 1.81 by 0.24 inches.

Suited for balanced portable audio

This adapter suits listeners who already own a player with a 4.4mm balanced output and headphones with a 2.5mm balanced plug. It is not for buyers whose source uses a different balanced connector, nor for anyone whose headphones terminate in a single-ended plug. It does not convert an unbalanced signal to balanced or vice versa.

4.4mm male to 2.5mm female balanced

The decisive specification is the connector pairing: a 4.4mm 5-pole male plug on one end and a 2.5mm 4-pole balanced female socket on the other. Only this exact combination allows the listed players and headphones to mate directly. Verify both connectors on your gear before purchasing.

Questions about this item

What does the 4.4mm balanced male connector do when plugged into my Sony NW-WM1A?

It connects the player's balanced output to a 2.5mm balanced cable, carrying left, right, ground and separate return signals through five poles for full balanced audio.

Which balanced standard does the 2.5mm female socket follow?

The socket uses a four-pole 2.5mm balanced layout, matching the pin-out used by Sony, Cayin, iBasso, FiiO, HIFIMAN and Lotoo portable players.

Will the 1.81 by 0.24 inch barrel fit through the cut-out on my FiiO M11 case?

The adapter measures 4.6 cm long and 0.6 cm wide, so it clears most recessed 4.4mm jacks on portable players and typical case openings.
