FiiO FT15 Over Ear Headphones - Black

Built for better listening. Combining cutting-edge planar magnetic technology with the natural beauty of North American black walnut, the FiiO FT15 is a premium open-back headphone designed for listeners who want detail, scale and a more engaging connection to their music. Its huge 101mm planar driver and ultra-thin, diamond-coated diaphragm bring advanced driver engineering to a carefully finished design, while the included alternative ear pads let you tailor the presentation to your listening preferences.

At the heart of the FT15 is an 800nm-thick diaphragm — an exceptionally thin membrane designed to respond rapidly to changes in the audio signal. FiiO’s full-surface diamond coating adds rigidity to the structure, helping control unwanted vibration and high-frequency breakup. Combined with a precision-formed voice coil and a specially developed uniform magnetic field, the driver is engineered for fast transient response, low distortion and precise reproduction of musical detail.

The expansive 101mm planar driver provides a generous vibrating surface, giving the FT15 the potential for deep bass extension, dynamic impact and a broad, open presentation. From the weight and texture of bass instruments to the detail in complex arrangements, its design aims to preserve the scale and contrast of the original recording. The open-back construction also allows air to move more freely around the driver, contributing to its spacious character. As with other open-back headphones, sound can travel both ways, so a quiet listening environment is ideal.

Despite its substantial planar driver, the FT15 has been designed with everyday comfort and compatibility in mind. A carbon-fibre headband helps keep the weight to approximately 425g, while the 24Ω impedance and 95dB/mW sensitivity make it easier to drive than many traditional planar magnetic headphones. It can work with capable portable players and dongle DACs, as well as dedicated desktop headphone amplifiers, giving you flexibility over where and how you listen.

includes fabric storage caseTwo sets of ear pads are included to let you adjust the presentation to your taste. The fitted suede pads favour fuller bass, warmer vocals and smoother highs, while the protein leather alternatives bring additional treble clarity and vocal definition. Swapping pads offers a simple way to fine-tune the sound for different genres and preferences.

The supplied 4.4mm balanced cable uses 6N monocrystalline copper and is accompanied by adapters for 6.35mm and XLR-4 connections, making it straightforward to pair the headphones with a range of compatible equipment. A fabric storage case completes the package, helping protect the FT15 when it isn't in use.

For listeners looking beyond conventional dynamic headphones, the FiiO FT15 combines large-format planar technology, natural materials and useful tuning options in a distinctive open-back design. It's a carefully specified choice for focused listening, whether you're exploring familiar recordings or working through a high-resolution music collection.
