  • Hi-Res Audio Certification
    The EX1II has been “Hi-Res Audio” certified by the prestigious Japan Audio Society, which means that it has passed certain audio quality tests, including being able to produce 40kHz sound tones. With this certification, you can be sure that the EX1II has a natural, cohesive sound that lets you listen to high-resolution audio the way it was meant to be listened.

    All Metal in a Sexy Black Housing
    The EX1II utilizes in its shell both stainless steel and aluminum alloy, giving it a pleasantly textured yet stylish look and feel. While the EX1II’s exterior is of a different color scheme compared to the original EX1, its lustrous black color is sure to capture the attention of many.

    Superb Sound Quality from Aerospace Materials
    The EX1II employs a titanium driver diaphragm, a material commonly used in the aerospace industry. This exceptionally lightweight material allows the EX1II’s driver to better handle transients and to overall give a more clear and powerful sound than the typical dynamic driver. With the EX1II you get both robust, full bass and stunningly clear treble, allowing you to be immersed into the music as if you were there with the artist.

    Better Vocals for More Pleasant Listening
    The EX1II has been specially tuned for more realistic and better-sounding presentation of human voices compared to the original EX1, making for a more neutral yet more satisfying listening experience.

    Controls to do it all
    The EX1II incorporates in-line music controls, a crystal clear microphone, and a call button. The in-line music controls perfectly work with the X1II, X5III, and other new FiiO products. In addition to the in-line music controls, the microphone and call button are also compatible with both the iOS and Android operating systems, which allows you to get outstanding sound quality without missing your calls.
    *Actual control scheme of the in-line controls will depend on the device’s system settings
    *Volume adjustment is not available for iOS devices

    Tilted In-Ear Design for more Comfort
    Compared to the traditional non-angled in-ear monitor, an IEM with a slightly-tilted design makes it easier for the wearer to get a more comfortable fit. And once you get it into your ear, you can easily wear the EX1II for hours without discomfort due to the angled design not requiring deep insertion for a good seal and thus sound quality.

    Tough yet Lightweight Polyurethane
    The EX1II employs a polyurethane cable, specially chosen due to it being light, flexible, but yet tough against scrapes. This ensures the EX1II is ready to go when you are.

    Leaving No Stone Unturned
    From the 3.5mm L-type gold-plated plugs, to the left/right channel splitter, to the left/right identification logo, every single last detail on the EX1II has been specially designed to give you an exceptionally pleasant experience.

    Strict Quality Testing for True Reliability
    Swing testing, Unit life testing, Button life testing, Material testing, Sound quality experience check, Cell phone compatibility testing, Wire durability testing, Fit testing, High temperature resistance testing, Anti-oxidation testing, Vibration intensity testing, Temperature testing, Anti-aging testing

    Multiple Ear tip Sizes
    Included with the EX1II are three different sizes of ear tips, allowing you to not only choose the most comfortable size for you but also allowing you to tune the sound the way you want it.

    The accessory pack is the same as with the Dunu Titan 1 or Fiio EX1, with a nice variation of eartips and a solid case. The box and packaging is similar to identical to the F1 and F3 models, which are nice and hassle free.

    The newer version of the EX1 maintains the same design as the first gen. which was made in collaboration with Dunu, meaning it keeps the identical form factor and excellent build quality from earpieces to plug. The shells are of excellent quality, mixing stainless steel and aluminum alloy giving the EX1ii an elegant and yet discreet appearance. Currently it is only available in black color.
    Despite the large 13mm driver the shells’ size is very compact, easy to fit and very comfortable on the ears. The design is of an open half-ear IEM with an angled nozzle, meaning the fit is very shallow and isolation level is on the low side, but this usually helps for a more open and airy sound presentation. It’s a good option for those looking for a middle ground between more traditional earbuds and in-ear sets, having some more isolation but a less intrusive fit.
    The cable is the same one used on the new F1 and F3, which is already of good quality. It’s thick enough, well behaved and almost tangle free. The attached cable wrap is a huge advantage as well. The L-angle plug utilizes in a TRRS (CTIA) to be used with many smartphones (not all models are compatible, though). The in-line control is placed on the right cable side as well. The control might add a bit of weight, but the whole EX1ii remains lightweight enough for the portable use.

    Overall, the new EX1 has a more conventional lively, v-shaped kind of sound, that parts away from the first Dunu Titan 1. Even after a long burn-in time (100~200 hrs.), the EX1 2nd takes a more aggressive presentation, with much more energy on the bass keeping the similar treble tuning from the first version.
    The bass of the EX1ii is strong, dominant, full bodied and has good depth. Layering and texture are of very good quality coming from the large titanium dynamic driver. Mid-bass is mildly enhanced, with some extra gain towards the upper bass region giving a warmer tone to lower instruments and lower mids in general. Sub-bass extension is great thanks to the open design, very effortless, though a bit less detailed and less controlled and a tad more congested than the so wider sounding Titan 1 due the extra emphasis at the mid bass part, but overall speed is very good with a good decay and very engaging.

    The midrange is quite clear and detailed, however, it takes a step back compared to the fuller and more forward bass and treble. Tonally, the mids are warmer than neutral, not too thick but not too lean either. Compared to the Titan 1, the whole midrange feels more distant keeping the traditional v-shaped response and does not sound as open or airy. The performance is still excellent, with very good timbre and dynamics that are quite impressive for a second model that’s being priced even lower. Male vocals sound somewhat recessed, and definitely not the strong point of the EX1, and while female vocals are more upfront, they still are not safe from certain degree of sibilance. The transparency is very good as well, but again not at the Titan 1 or Soundmagic E80 level.

    Treble detail and extension are very impressive; again, the open half-ear design is the key here. Texture and resolution are very good as well, sounding very open and airy. Overall tone is towards the cool side, and while the extra treble emphasis brings lot of details, it makes the new EX1 a non-forgiving and too aggressive IEM that at a longer listening time can get tiring. Cymbals and other upper instruments can be more exaggerated making the timbre a bit less natural. Next to the RHA MA750, the treble on the Fiio EX1 is less sharp but stronger at the lower treble region. The Dunu Titan 1 showed a bit more refinement and flatter response while still classifying under the bright signatures. The lively presentation is still spacious and well separated, with above than average stage size and nice positioning, and boasts better separation than LZ A3, AAW Nebula, Shozy Zero and Advanced Model 3.

    With a same design and a new smartphone compatible cable, the second EX1 version brings a more conventional sound than its predecessor while sitting at an even lower price. Build quality is very solid and fit should be very friendly for most users (at the price of a lower isolation level). The new tuning may not be what the fans of the 1st version should look at, but at its current price it has a great value among the sub $100 range earphones.
