The FiiO EX1 design is an obvious combination of an in-ear headphone model, as well as an earbud. This only means that it is not completely sealed in the ear. Rather it sits there, supported through the tragus, as well as the anti-tragus. One thing I have observed upon using this earphone is that it is designed for use cable down. This is quite a popular design among Japanese companies.

I also like the fact that the earbuds are well made, with a housing which is completely made out of metal, making it really cool looking and sturdy at the same time. Each housing comes with a colored metal ring in order to differentiate it better, having L and R designations printed on its shell. As you pick these little, shiny earphones, you can immediately observe that they are amazingly lightweight, which is quite surprising, given the fact that it comes with solid construction material, as well as a big 13mm driver within.

Product Features

  • Sound Quality:What this in-ear monitor headphone is famous of is the fact that it can still produce high sound quality in most genres, from classical, to rock/pop music, and everything else in between. I personally love the bass produced by this IEM. It is not necessarily huge and overwhelming in its qualities, but it is clean, good and deep. The mids are recessed, and the treble is tolerable.The only issue with sound quality is its poor isolation. As such, it is not recommended for use outdoors, such as when you are in a subway, train or bus. Even though the sound leakage may not really be too bad, it may not perform well in noisy areas. However, if you are planning to use it indoors, no problem because it produces great sound.FiiO EX1 Nanotech Titanium Diaphragm In-Ear Monitors
  • Aerospace Nanotech Titanium Diaphragm: The model’s diaphragm serves as the heart of the production of sound. Since it uses titanium, a substance which is lightweight, and comes with good speed for sound conduction, it became possible to design a complete range of dynamic driver with this material, pushing the breakup frequency over the audible range, making sure of a smooth and clear high production frequency.FiiO EX1 Nanotech Titanium Diaphragm In-Ear Monitors
  • Dynamic IEM Earphones: This in-ear monitors use a top of the line, high quality dynamic transducer, that works together with a nano class titanium diaphragm. It is quite different from the standard dynamic transducer, as it has the capability of creating a perfect transient response while still retaining an energetic and natural sound, that is, producing a delicate and clear layering, powerful and thick bass response, together with great treble clarity.

It also comes with an outer sheath that is made out of medical grade TPE which makes it possible for minimum microphonics, as well as maximum bio-compatibility, thus avoiding issues, such as skin allergies.FiiO EX1 Nanotech Titanium Diaphragm In-Ear Monitors

  • Amazing Ergonomics: FiiO EX1 uses an amazing, and ergonomic nozzle design, working with a little, and rounded on-ear driver for its housing, together with a shallow in-ear nozzle, thus making sure of comfort even when worn for a long time.
  • Great Sound Quality: The sound provided is described as unique in the way that it excels really well with both bass and treble categories. This is something which is not really the standard with single driver units. Aside from high quality upper mids, it also supports really well on the lows, which are described as resolved, wonderfully tight and detailed.
  • Portable Overall Design: The appearance of this in-ear monitor is quite attractive. The earphones are shiny, and fairly lightweight, thus adding further to its convenience. Since the earphones are light, it is less prone to fall off from your ears as you keep moving around. The cable is also well thought of and lovely. The lower half of the cord is wrapped in a way that reduces tangle. On the other hand, the top half comes with a soft rubber coat that eliminates microphonics, thus creating a great combination.


  • Some issues with durability: According to some reviews coming from users, this in-ear monitor comes with some issues related to durability, such as the headphones breaking off. However, this issue can be addressed with extra care.

It is quite clear that the manufacturer behind the FiiO EX1 model takes a whole lot of pride in the process involved in tuning this unit in order to get the kind of sound that they are envisioning. The sound that this unit produces is really good. It is unique in a way that it works really great in both bass and treble. This is quite new for a single driver model. Also, the detailed upper mids level is quite similar to that of an old Hifiman REO, as well as an m3 earphone.  It does not offer too much decay or even sub bass, but it produces that kind of punch that can make you feel its hearty presence. This means that Rock genre songs would exceptionally work well with this model.

I personally believe that this IEM is a very promising option. It has managed to produce high quality sound which extends over the needed frequency. Fans of Asian music would certainly love this because it is almost perfect for the genre. At the same time, the fact that it is a budget in-ear choice, together with its amazing accessories and stellar build, makes this unit a great value option. Even though some may have reported issues when it comes to durability, taking the necessary steps to take care of this unit is the solution to the problem. All in all, I would recommend the purchase of the FiiO EX1 IEM earphones.
