FiiO FT5 Headphones

The open-back design allows air to pass through the earcups, which prevents pressure buildup and creates a wider, more natural soundstage. While this provides an immersive, speaker-like experience, it also means sound will leak out and you will hear ambient noise from your surroundings.

With an impedance of 38 Ohms and a sensitivity of 105dB/mW, the FT5 is relatively efficient for a planar magnetic headphone. While you can drive them with a phone or laptop, using a dedicated DAC or amplifier will help you get the most out of their dynamic range and detail.

The FT5 weighs approximately 456 grams. While the magnesium-aluminum alloy construction keeps the weight manageable, they are substantial headphones; the 3-axis swiveling earcups help distribute that weight evenly for a more comfortable fit over time.

These drivers are designed for speed and precision. You can expect a highly detailed, fast response across the frequency spectrum, with tight, controlled bass and a clear, expansive presentation that is characteristic of high-end planar magnetic technology.

Because of the open-back design, these headphones offer no active or significant passive noise isolation. They are best suited for quiet, indoor environments where you can fully appreciate the soundstage without outside interference.

The FT5 comes with a high-purity, silver-plated monocrystalline copper cable. It features interchangeable audio plugs, allowing you to easily switch between different connection standards depending on your source equipment.
