FiiO FD15 In-Ear Monitor

The Tesla Valve is an acoustic design that enhances low-frequency performance. It allows the earphones to produce deeper, more resonant bass without sacrificing the clarity or detail of the mid and high frequencies.

No, the FD15 is designed strictly for high-fidelity audio playback and does not feature a built-in microphone or remote controls.

The 316L stainless steel construction provides a rigid, durable housing that minimizes unwanted vibrations. This helps ensure the sound remains clean and accurate, contributing to the 'grounded' and dense auditory experience the FD15 is known for.

Yes, the FD15 features a detachable cable design. It comes with a high-quality Furukawa single crystal copper and silver-plated cable, but you can swap it out for other compatible cables if you prefer.

No, the FD15 does not have active noise cancellation. It relies on passive noise isolation, which is achieved by the physical fit of the ear tips within your ear canal to block out external sound.

The large 13.8mm driver combined with the Magnalium DLC diaphragm delivers a balanced, high-resolution sound. You can expect a bright, transparent signature with refined detail in the highs and a powerful, controlled low-end.
