The GIGAS Series takes its inspiration from the Greek word "GIGAS," meaning "giant," which symbolises high output power.

This product series was born out of our release of the JT7 planar over-ear headphones. The JT7 has a relatively low sensitivity and demands high output power from the source device, but source equipment on the market with sufficient power are often quite expensive. To address this, we have tailored the GIGAS Series specifically for entry-level planar headphones from FiiO and other brands, delivering massive driving power at an affordable price—to fully unlock the true sound quality of full-size planar headphones.

The GIGAS 1 is a compact, high-power headphone amplifier specially designed for desktop usage.
