I would like to thank FiiO for providing me the Q3 as review sample. I am not affiliated with FiiO beyond this review and these words reflect my true and unaltered, opinions about the product.
The FiiO Q3 is available under the following official FiiO Online Stores;
Package and Accessories:
The device came in pretty small box with the FiiO brand logo on the top that is wrapped with a cardboard in black color with the illustration of the Q3 and some brandings on the top.
This box contains the following items;
- 1 x FiiO Q3 Portable DAC/AMP
- 1 x USB A to USB Type-C cable for file transfer and charging
- 1 x 3.5 mm to 3.5 mm Cable
- 1 x USB Type-C to USB Type-C Cable
- 1 x Lightning to USB Type-C Cable
- 1 x Protective Pouch
- 1 x Silicone Stacking Pad
- 4 x Rubber Stacking Bands (2x with Small & 2x with Bigger Diameter)
- 1 x User Manual & Warranty card
Design & Build Quality:
The FiiO Q3 is a portable USB DAC & Amplifier that is pretty small and lightweight thanks to its dimensions with about 105x59x12.5mm and total weight around 110grams.
The FiiO Q3 is also a very well made device same as other FiiO branded product that I have reviewed or experienced before. It features a CNC machined aluminum alloy chassis with a sand blasted surface that has a black finish.
The sides of the device do have a curved shape that makes it comfortable to hold in your hand. On the top of the device are the FiiO and the Hi-Res Audio logos in white color.
At the rear side of the device are two screws, two switches (one for bass and one for charging on/off), the multifunctional button for “Gain” & “DAC Filter” selection and the USB-Type-C port for both data and charging purposes.
On the front of the device are the 3.5mm single ended phone/lineout, 2.5mm & 4.4mm balanced outputs and the volume potentiometer that turns also the device on and off.
The potentiometer has a nice red ring on the front and offers a nice grip.
Near the potentiometer is an LED that lights up in different colors (blue, red, green, etc.) and gives information’s of the actual operation/codec status.
At the backside of the Q3 are some industrial certifications and the THX AAA detail in white color.

E) Battery Life:
My results are pretty close to the specs that have been shared by FiiO, which I think are pretty good for such a small device. I have tested the battery life with the FiiO FH3 and FiiO FH7 In-Ear Monitors under the following condition;
- Line-In : up to 18 Hours
- USB Out (PO) : approx 9 Hours
- USB Out (Balanced) : approx. 7.5 – 8 Hours
*Volume about %50, @ Low Gain
F) Interference Shield:
The FiiO Q3 comes with a high strength all-aluminum body that has an additional copper-nickel shielding, which offers 360° radio frequency absorption, even when you use the device side by side or stacked with a source like a Smartphone or Tablet.

The FiiO Q3 is a DAC/Amplifier with a close to neutral and detailed presentation that offers a good level of treble detail, sharpness and extension, with nice amount of airiness. The Q3 shows in general a pretty natural and linear tuning in any frequency region. The overall toning on the other hand is neither too sterile/dry nor to warm.
PS: The review is written after a burn-in process of about 70 hours mainly based on my experiences with the FiiO FH3 and FiiO FH7 In-Ear Monitors.
3.5mm Single Ended versus 2.5mm/4.4mm Balanced:
Both the 2.5mm & 4.4mm balanced outputs of the FiO Q3 do offer a darker background and slightly more dynamic and powerful presentation compared to the standard 3.5mm single ended output. The subbass has more depth and intensity. The 3.5mm Single Ended output shows a softer tonality and a shorter treble extension. If you have an earphone/headphone with highlighted treble response, the 3.5mm SE output will offer a better synergy.
The FiiO Q3 shows a good level of subbass depth that will meet the expectations from a DAC/Amplifier. The bass quantity will be quite enough for most listeners and genres, while you have the option to increase the quantity to a next level (about 6dB) with the bass boost switch. But to be honest while the boost doesn’t affected the midrange (with exception of a slightly midbass hump that was somewhat noticeable with male vocals) and treble to much, the bass sounded a bit less controlled and loose to my ears.
It is very enjoyable to hear the deep and rumbling subbass of the Q3, especially in songs like Massive Attack’s “Angel” and Portishead’s “It Could Be Sweet”.
FiiO Q3 has a fast, pretty emphasized and controlled midbass performance, without to show remarkable negative situations such like a midbass hump or mixings. The Q3 offers a sufficient level midbass quantity and intensity for most listeners, inclusive bassheads, and is able to produce soft or strong bass notes depending of the record.
The bass response is very fast, from percussion instruments like drums up to the guitars in metal music. Electro- and Bass guitars do have a good level of rumble, speed and depth, while the bow pulls of the contrabass that can produce a high level of rumble/vibrations are pretty audible.
The FiiO Q3 can handle the kick and drum beats of trash metal in terms of bass speed and tightness, so it will satisfy the listeners with its dynamism.
The FiiO Q3 offers a pretty detailed and natural midrange character, with a good level of airiness and clarity. The midrange is soft but also lively that doesn’t tire your ears.
The Q3 has a deep pretty deep lower midrange presentation that is neither far recessed nor too much highlighted. Male vocals do sound very clean, have good depth, and do sound quite vivid and clear. Female vocals on the other hand are reproduced in a quite transparent, airy and detailed manner, with good level of extension and control. Those who listen to female vocals a lot will find what they are looking for in Q3.
The instrument tonality of the Q3 is neither bold nor too dry or thin and can be in general described as pretty natural, while the timbre of instruments is clear and distinct. Instruments like guitars are slightly bright and do have good extension, while the violin performance of the Q3 in terms of emphasis, extension and detail retrieval is very successful.
The FiiO Q3 is also a quite successful DAC/Amplifier when it comes to the separation an placement of instruments and vocals.
Upper Midrange & Treble:
The FiiO Q3 has a clear, strong and sharp upper midrange presentation with transitions that are in general fairly controlled. The upper midrange of the Q3 is well-tuned and doesn’t show any unnecessary over-sharpness/brightness that could tire your ears over time. From female vocals up to instruments such like violins and pianos, the extension, emphasis and detail retrieval of the Q3 is pretty good.
The FiiO Q3 has a close to neutral, transparent and bright treble presentation with good level of airiness and extension. I really enjoyed the treble tuning that is smooth but don’t falls short in any register of this region. Every song, from Chopin’s “Nocturn” to Gogo Penguin’s sharp jazz, sounded successful in terms of treble extension, intensity and sharpness, which brings me to the conclusion that the Q3 performs above its price range when it comes to the treble performance.
The lower treble region is slightly more emphasized and detailed compared to the upper treble area, which sound otherwise pretty good in this regarding. The general treble presentation is controlled and well adjusted, so that it doesn’t tire your ears even after longer listening periods. Instruments like hi-hats pronounced and do shows a good level of extension, while crash and ride cymbals are fast and detailed. Treble range has a very good speed in metal and jazz music and shows a good amount of intensity and brightness in genres such as EDM or Pop without to disturb your ears.
The FiiO Q3 has a pretty large stage for a precise and clear placement and separation of instrument and vocals. The neutral tonality and the wideness of the stage do help to make a quite spacious and airy atmosphere. The soundstage shows a good level of wideness, while the depth is on an average level.
FiiO offers with the Q3 a very compact and affordable DAC/Amplifier with great specs like the THX AAA28 Amplifier Module or the XMOS208 Chip for Native DSD up to 512x and lots of output options that has been crowned with a sound capability that performs wide above its price tag.
Pros and Cons:
- + Natural Presentation & Timbre
- + Bass Response
- + Midrange Tonality
- + Treble Control & Extension
- + THX AAA28 Amplifier Module & Good Shielding
- + Lots of Output Options (3.5mm SE, 4.4mm & 2.5mm Balanced)
- + Build Quality
- – Bass authority when Bass Switch is On
- – Bluetooth Connectivity would be great (maybe not a real con)
- – No Protective Silicone Case included
