Custom articulated dual drivers for incredible separation and beautiful detail in the high end with lush well-defined response in the lower and mid frequencies.

Magnet TypeNeodymium

Audiofly headphones use a neodymium magnet for longevity; the alloy has a unique crystalline structure that has a greater resistance to being demagnetized.

Frequency Range18-22KHz

The AF78 has an extended frequency response across the entire spectrum with a range of 18Hz - 22Khz for a massive soundstage with impressive detail and separation.

Cable Length1.2m

Our high spec Audioflex braided cable not only has kevlar reinforced conductors, but a CORDURA® brand Nylon outer sheath for superior strength and amazing durability.

Plug Type3.5mm gold plated

We use gold plated plugs not because they look good, but because gold is the best conductor with the greatest resistance to corrosion giving you better sound transmission that is durable.

Impedance16 Ohms

The AF78's dual drivers have a low impedance of 16 Ohms. This is ideal for low powered devices like iPods® and iPhones® giving enough headroom so they have no trouble producing plenty of volume.

Sensitivity108dB at 1kHz

At a rating of 118dB, our drivers have a higher than average sensitivity. This means they are efficient with the power they use and don't need to be driven as hard to sound their best, making them ideal for modern portable music players.
