FiiO FH5s/FH5s Pro In-ear Monitors

Experience and expertise in tuning

Excellent materials and solid data are important parts of a good foundation for sound. FiiO headphones have been sold in more than 70 countries around the world, allowing us to accumulate a large amount of user opinion data. This data has helped us to continuously improve the sound of our headphones, and the FH5s represents our best work to date. It's easy to become a fan of its sound, but hard to get tired of it!

Relieving stress to protect your hearing

The semi-open design at the rear cavity was refined through computer simulations to ensure the air pressure at the front and rear cavities are balanced – resulting in larger soundstage, more comfortable listening, as well as a natural sound.

Fine-tuned to perfection

Within the FH5s, we have accurately calculated how each driver should focus on the low, mid, high, and ultra-high frequency response ranges for great sound. The results? Robust bass, clear mid-range vocals, and exquisite yet non-fatiguing highs and ultra-highs.

8 exciting ways to listen

3 tuning switches for lows, mids, and highs

While the default sound tuning will suit the taste of most audiophiles, there are also three tuning switches controlling the bass, mids, and treble for further customization. Whether due to listening to a certain kind of music or due to your taste, find a sound that perfectly fits you with the tuning switches.

TRISHELL Acoustic Design

Technology inspired by supercars

The FH5s employs the TRISHELL "sandwich" structural design, with the 5-axis CNC machined aluminum-magnesium alloy rear shell, body, and front covers solidly fixed together at 3 points to greatly reduce excess resonance and distortion. Just like an exotic supercar with its super-rigid chassis to maximize performance.

Impressive in-hand

The shell is made of CNC-machined aluminum-magnesium alloy, which is firm enough to even reduce the unwanted resonances within! Here, the sturdiness of the shell actually improves your music.

Massively comfortable in the ear

The third-generation ergonomic curve is optimized for a perfect fit around the human ear for an extremely comfortable experience.

Magnificent at first sight

The open-air mesh guides perfectly blend with the layered "dragon scales" on the faceplate of the FH5s to give it a powerful, stunning design. Whether you choose the black and gold or silver and gold colors, the FH5s maintains its striking looks.

Better sound in a brand new 2+2 architecture

A new double dynamic driver and double balanced armature acoustic architecture was developed for the FH5s. Replacing the balanced armature used for mid frequencies in the original FH5, the new mids dynamic driver provides better vocals and soundstage in the FH5s. The dual dynamic driver setup connects the bass and mids together more smoothly and coherently, as well as covers a wider range of frequencies and provides a larger soundstage. It simply creates a better sense of atmosphere and truly envelops you into the music!

12mm beryllium-plated dome + PU gasket dynamic low frequency driver

The third generation 12mm Tesla low-frequency dynamic driver is engineered to give extremely high-quality bass. With its rigid yet flexible polyurethane polymer surrounding gasket + beryllium-plated diaphragm dome and N52 magnets capable of 1.5 Tesla, this driver is capable of some seriously deep and potent yet controlled bass.

6mm beryllium-plated dynamic mid frequency driver

The low and mid frequencies are also taken care of by beryllium-plated diaphragm dynamic drivers, which are carefully tuned to smoothly connect to the other drivers. The results are luscious yet pure vocals that are easy to get addicted to but hard to stop listening to!

Time-tested Knowles TWFK-30017 high frequency driver

Treble is handled by the Knowles TWFK-30017 balanced armature driver, which has proven to be wildly popular among music listeners. This driver is placed directly in the sound tube to be as close to the ear as possible for less high-frequency loss and better extension, giving the FH5s its exquisite treble.

One worthy upgrade！Standard FH5s VS Premium FH5s Pro

In addition to the standard FH5s, there is now also the more premium FH5s Pro – more options for more ways to listen!
