Big thanks to the folks at FiiO for sending me this demo unit. I am not being compensated by them for this review in any way. I’m simply giving my impressions of the Amp/DAC. Read on to find out what I thought!

So as for the question of does it have enough power? Stick around to find out in this FiiO Q1 MK II Review because..

Final Grade

Now without further ado, let’s get rolling!


I’ve demoed a lot of amps at this point, and the differences in sound between them are pretty subtle. For the most part, something around $100-200 is going to be just fine for the majority of people and I stand by that wholeheartedly.

There are some amps in higher price ranges that get my highest endorsement (The Chord Mojo is a fine example), but by and large you’re not going to be able to tell a huge difference between most solid state Amps and DACs below that price range.

People like to make being an audiophile this hugely complicated thing when in reality it’s just not. The Law of Diminishing Returns runs rampant in this hobby, and prices get ridiculous fairly quickly. There’s also just way too much out there and at this point it’s becoming a prick contest. There, I said it. Don’t really care anymore.

Find a good combo of Headphone + Amp + Source (Like Tidal) that isn’t going to leave you pan handling at your towns busiest intersection, and call it a day. Lol. Those people aren’t actually poor and homeless by the way. Poor people/bums are usually seen traveling with what little cargo they have. Not making cardboard signs and wearing reflective vests. I saw one just the other day get into a nice truck at the end of their “shift.”

It’s even more obvious when they’re all working the same corners at the same times of day week after week.

Anyways, let’s get into the FiiO Q1 MK II and find out if it’s worth your money!


The Q1 feels substantial in your hand, and is heavier than my favorite budget desktop, the FiiO E10K.

It feels slimmer, sleeker, and longer, length and width wise. It’s roughly the size of a deck of cards.

The volume potentiometer feels incredible to the touch, and very solid. This doesn’t feel like it’s price would indicate. The problem with it is that when the Q1 is laying on your desk, it’s very hard to just turn the volume because the unit is not raised up. I have to take the Q1 with my left hand, then turn the volume up with my right. A minor nit pick but should be noted if you’re used to units like the Magni, Objective 2, or even the E10K is much easier to adjust volume on.

Yes, the rubber foot will help elevate the unit so you can more easily turn the knob. But: It’s still cumbersome and still more of a chore than I would like. The unit still tends to move around a bit much when you’re adjusting the volume with the rubber foot in place.

With the E10K + those really great adhesive buttons on the bottom that enable the unit to stay securely in place, I can put my pointer finger on top of the unit, thumb to the left side, and use my middle finger to adjust the volume fairly easily. This is especially great at night when all the lights are off and you can hardly see. 😛

Aside from that..

All of the switches and jacks on the unit feel good as well. It seems like great care was taken into designing the amp/dac as well as using high quality materials.


Let’s talk about features..

Features & Usage

Right off the bat, it comes with:

  • Lightning cable for use with your Apple products/iPhone, etc.
  • 3.5mm interconnect cable for use with your Android phone.
  • Micro USB cable for use with your Laptop/PC.
  • 4 Rubber Bands.
  • A Drawstring Carrying Bag.
  • A Silicone Base Pad or Rubber foot.

There’s a few options at your disposal here. On the back, you’ve got a micro USB slot for your laptop, a gain switch, and a bass boost.

On the front, there’s a 3.5mm jack for your headphones, a 3.5mm line out with DSD compatibility, and a 2.5mm jack that you can use with balanced headphones/cables.

If you have an Apple phone, just use the supplied lightning cable that comes in the kit. If you have an Android like me, just use the 3.5mm interconnect that also comes with the kit. It’s a good length and sounds great regardless. Here’s a few images of the Q1 paired with my LG phone:

The DAC chip here comes in the form of an AK4452, which is capable of supporting 32-bit, 384kHz files as well as DSD256. The sample rate of 384 doesn’t matter much. The bit depth of 32 is the difference in sound quality and it DOES make a difference. Related: Bit Depth vs Sample Rate. 

The Battery is an 1800mA, which lasts an average of 10 hours. This does not draw power from your phone when plugged in so that’s nice as well. Just make sure to charge it via it’s micro USB cable.

Bass Boost and Gain

I enjoy both the bass boost and gain switch. The bass boost is done very tastefully, but unfortunately the gain will have to be on full time with this unit unbalanced. This is my biggest complaint with the Q1 overall. It just doesn’t have enough power.

7mW into 300 Ohm to be exact, and 75 into 32. That’s. really. meh. A unit like the Oppo HA2 provides 30mW into 300 Ohm and is extremely versatile. It’s also discontinued and costs around $350 but it’s been my staple for quite awhile now. The Sennheiser HD600 requires 20mW to sound loud enough.

Still, someone looking to buy a Q1 will likely be more of a casual listener than an outright audiophile. Even so, with the balanced 2.5mm you’re getting around 220mW into 32 Ohm.

The E10K for comparisons sake provides 200mW into 32 Ohm and I’m able to drive both the HD600 and 650 fairly easily.

Aside from all that, there’s another complaint I have.

The location of both the gain switch and bass boost are kind of cumbersome to get to when you’re in the middle of a heated music listening session. Add to that, both switches are entirely too small. So not only do you have to reach around back to get to them, but it’s fairly difficult to even flick either of the switches.

On the E10K, the gain was on the back and the bass boost was on the front. However, both switches were the perfect size and super easy to flick. This is because they stuck out so you could easily get your finger on it.

On the Q1, the switches are flat as a pancake, round, and small. Just not an ideal combination in my estimation. I found myself turning the unit around and using laser like focus just to switch on the bass. I have pretty big hands and fingers, so that didn’t help either.

On the plus side, using the Q1 with my phone was a pretty fun time. I took a trip down to the beach with mom in January, and used the provided rubber bands and 3.5mm interconnect cable provided as I didn’t have an Android OTG. FiiO kind of made this more geared towards Apple users.

On the way to the beach getting ready to pair it with my phone.

I mostly used the unit with the Tin Audio T2 which made a pretty sweet combination regardless. Being that the T2 is low impedance and high sensitivity, it worked very well with the low power output of the Q1. As I mentioned before though: The gain had to be on full time, and it took turning the volume most of the way up just to get it loud enough. In fact, you likely won’t hear anything until the knob gets to around 2 o’ clock, which was quite a shock. I suppose I’m used to units like the JDS Labs Element with lots of power at this point in my listening “career”. Lol.

So all in all, the power dilemma plus the annoyance of the switches brings the score down a bit.


Let’s take a break and watch a video!

So how does it sound?


The sound of the Q1 is pretty warm and smooth. I really enjoyed it.

It’s hard to actually describe the sound of an Amp/DAC since the differences between them are very subtle. Related: What is a USB DAC?

Fortunately, when using other amps to compare it becomes more clear. The E10K as well as the A3 are both going to sound more sterile, perhaps a bit crisper and brighter than the Q1. The A3 being the cleanest and most neutral sound (E10K is a bit grainy at times, but it’s not noticeable unless you have other amps to buffer). The Q1 is a very warm, smoothed over sound that makes you want to kick back and relax. It’s really quite lovely!

It also makes a great pair with the Sennheiser HD 600 because it tends to tame down the somewhat annoying 3k area of the 600.

Even so, you’re still getting loads of subtle details in the mix. I was finding myself stunned at how clear everything was. The Q1 really makes phenomenal use of air and spacing, to the point of you rewinding the track and catching subtleties in the music that you never heard before, even with tracks you’ve grown accustomed to!

I think the Q1 is a fine choice for someone with low impedance, high sensitivity headphones. However, if you ever plan to upgrade it simply won’t work in my opinion, at least as far as using it unbalanced.

I did get a chance to A/B test it against an E10K and it does sound smoother, warmer, and a bit more musical than the more sterile sounding E10K. That Amp/DAC is amazing in it’s own right and I’m not knocking it at all. It does sound a bit rougher around the edges in comparison to the Q1 MK II.

I wouldn’t call the difference huge, but I was surprised that I could hear an audible difference in the way the music was presented to me. I felt like the E10K was more detailed but at the same time a bit more brash. I would liken the difference between these 2 to the relationship between the colder sounding HD600 and the warmer, more lush HD650 which tends to smooth out the rough edges in music.

If you’re looking for the perfect budget desktop solution under $100, the E10K is awesome and sounds fantastic.

With the balanced 2.5mm on the Q1 you’re getting more power, but it’s an inconvenience for the average person. Most people aren’t going to want to purchase a separate set of balanced headphones, or re-cable their headphones after they’ve already invested in the Amp/DAC.

I just want to be able to quickly and easily plug my headphones in and get a fantastic sound with plenty of headroom. With the Q1 as is, that’s not entirely feasible.

Still, the Q1’s sound is rather impressive for the price, and it deserves high marks indeed here.


What’s my final grade?

Final Grade

I’m going to give the Q1 a B+/A- today.

I like the fact that I can use it with my phone and have it as a desktop amp. It’s built very well, and has some nice features and connections. It’s pretty versatile in that you can use it with your PC/Laptop, iPhone, or Android.

The downsides in my opinion are lack of on-board power without the need to use it balanced, the location and size of the gain/bass boost. The fact that I’m not hearing music until around 2 o’ clock on the dial is a problem, regardless of the other port. It’s also quite awkward to turn that volume knob, so a few points were docked for ease of use.

If you’re a casual listener and need the best option for both your phone and laptop, the Audioquest Dragonfly Red is the solution. It’s the size of a thumb drive, but packs a ridiculous amount of power (2.1W), and the sound is gorgeous.



If you’re still interested in the Q1, it is an excellent option for folks with low impedance, high sensitivity headphones or people with balanced headphones/cables.
