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

OFHC stands for Oxygen-Free High Thermal Conductivity.
OFHC copper is also referred to as Oxygen-free copper (OFC). It is highly conductive.
Characteristics of OFHC copper are more ductility, high thermal & electrical conductivity, high impact strength, more resistance and an easier welding process. Conductivity in ordinary metals, such as copper or silver, is limited by the presence of impurities and other defects. By reducing the extremely low level of impurities the inherent properties of copper are enhanced to a high degree. The OFHC metals thus obtained have a copper content of 99.99%.
