FiiO FT1 Pro Open-Back Planar Alternatives: 6 Similar Picks Compared

How each alternative compares

HIFIMAN Open-Back Planar Magnetic Headphones

The HIFIMAN HE400SE uses a planar magnetic driver in an open-back design, similar to the FiiO FT1 Pro. It weighs 13.8 ounces, which is significantly lighter than the FT1 Pro at 2.29 pounds. This makes the HIFIMAN option better for portable listening sessions where carrying a heavy pair of headphones is cumbersome. The FT1 Pro offers a wider lateral soundstage due to its larger 95x86mm driver and specialized coatings. If you prioritize long-term comfort and reduced neck strain during extended home listening, the HIFIMAN HE400SE is a practical choice. It sacrifices some of the massive soundstage width for a more manageable form factor and lower weight.

Fosi Audio 97mm Open-Back Planar Headphones

The Fosi Audio i5 features a 97mm planar magnetic driver, which is slightly larger than the FiiO FT1 Pro’s 95x86mm unit. Both are open-back wired headphones designed for studio use. The Fosi model is described as having a large driver for expansive sound, targeting critical listening. The FT1 Pro emphasizes a 1μm ultra-thin diaphragm and dual-coating technology for high-frequency resolution. If you prefer a driver size closer to 97mm for potentially broader acoustic coverage, the Fosi Audio i5 is a strong alternative. The FiiO FT1 Pro remains the better option if you value the specific 28-nanometer chip-level manufacturing process and the detailed sapphire and aluminum coating technology for improved audio clarity.

HIFIMAN Edition XS Open-Back Headphones

The HIFIMAN Edition XS is an open-back planar magnetic headphone with a stealth magnet design. It weighs 14.3 ounces, making it much lighter than the FiiO FT1 Pro at 2.29 pounds. This weight difference is significant for users who find the FT1 Pro too heavy for extended wear. The Edition XS is ideal for home listening and critical audio evaluation. The FT1 Pro offers a wider soundstage and more detailed high-frequency response due to its specific driver coatings. If you want a lighter, more portable planar option that still delivers accurate full-range audio, the HIFIMAN Edition XS is a suitable swap. You give up the FT1 Pro’s massive driver size and specialized coating tech for better comfort.

HIFIMAN Sundara Closed-Back Planar Headphones

The HIFIMAN SUNDARA is a closed-back planar magnetic headphone, unlike the open-back FiiO FT1 Pro. It weighs 15.2 ounces, which is lighter than the FT1 Pro’s 2.29 pounds. The closed-back design provides sound isolation, which the FT1 Pro lacks due to its open acoustic design. If you need to prevent sound leakage or block out external noise during studio monitoring, the SUNDARA is the better choice. The FT1 Pro offers a wider, more natural soundstage typical of open-back designs. The SUNDARA sacrifices that expansive acoustic space for a sealed package. It is best for users who prioritize driver quality and isolation over the open, airy feel of the FiiO FT1 Pro.

ASUS ROG Kithara Open-Back Headphones

The ASUS ROG Kithara features a 100mm planar magnetic driver, which is larger than the FiiO FT1 Pro’s 95x86mm unit. It weighs 11.2 ounces, significantly lighter than the FT1 Pro. This headphone is designed for gaming and includes a microphone, which the FT1 Pro does not list. The open-back design shares similarities with the FiiO model, but the Kithara offers multiple plug options and a robust metal build. If you need a microphone for voice chat and a lighter pair of headphones for long gaming sessions, the ASUS ROG Kithara is a practical alternative. The FT1 Pro is better for pure audio fidelity and studio monitoring without the gaming-specific features and included microphone.

Philips Over-Ear Open-Back Studio Headphones

The Philips SHP9500 is an open-back over-ear headphone that weighs 1.19 pounds, which is lighter than the FiiO FT1 Pro at 2.29 pounds. It is designed for home and studio use, offering a wide, natural soundstage. Unlike the FT1 Pro, which uses a planar magnetic driver, the Philips model is a dynamic driver headphone, though the data does not specify the driver type beyond the acoustic design. The SHP9500 prioritizes comfort and wired reliability. If you want a lighter, more comfortable option for general home listening without the weight of the FT1 Pro, the Philips SHP9500 is a solid choice. You give up the specific planar magnetic technology and ultra-thin diaphragm details of the FiiO model.
