Headphone Adapter 2.5/3.5mm to 4.4mm
Convert your 2.5mm or 3.5mm headphones to fit 4.4mm Pentaconn balanced outputs.

2.5/3.5mm to 4.4mm? No problem
The use of 4.4mm Pentaconn outputs is becoming more and more common, and not just in iFi products. Fed up of not being able to use your beloved 2.5/3.5mm single-ended headphones with devices sporting a 4.4mm Pentaconn output? Well, now you can. Our specialist 2.5/3.5mm to 4.4mm Headphone Adapter allows you to do just this with ease.

Please note: negative balanced signals are not connected to ground in the adapter, enabling a 3.5mm single-ended headphone connector to be converted for use with a balanced 4.4mm output without risk of damage to the amplifier. This adapter does not convert a single-ended connector into a balanced one. The connection remains single-ended.

Ruby ★★★★★ Oct 22, 2026

Wasn't sure a little adapter could make this much difference, but plugging my 3.5mm headphones into the 4.4mm Pentaconn output on my amp gave me noticeably cleaner sound. Connection is tight with no wiggle, which is exactly what I wanted.

Eli ★★★★★ Oct 20, 2026

Finally got rid of the adapter mess on my desk—this little thing takes both my 2.5mm and 3.5mm cables and slots them cleanly into a 4.4mm balanced jack without any wiggle. The grip is tight enough that I don't worry about it coming loose mid-session, and it's solved my connectivity issues instantly.

Finally an adapter that handles both my 2.5mm and 3.5mm headphones without any fuss—plugged my IEMs into a 4.4mm balanced amp and the connection is snug, no crackle when I move around. Takes up almost no space in my bag, which is a huge plus.
