The USB-C port is OK; the cable isn’t seated perfectly snugly, but this is a common theme even on mobile phones that cost over 1000 euros, so for a stationary desktop unit, this is more than acceptable.
Step 5:Turn on the power switch (turn up the volume); (Note:The power switch is also the volume control knob. First up is the FX-Audio DAC-X6 Mini. This particular headphone amp gives you great quality sound but at a more affordable price than with some competitive models. With USB, optical and coaxial S/PDIF inputs can fit with most home audio systems, and RCA output can be connected to an amplifier or powered speakers on your desktop. Built-in Hi-Fi headphone amp chip can drive most 16ohm to 200ohm headphones. It’s a really well thought out selection of inputs, outputs and functionality to get anyone started on their audio journey.Therefore, when Fosi reached out recently and asked if I would be interested in trying out and possibly reviewing any of their products, I said that I would be interested in giving the K5 Pro a whirl and seeing what they could offer in this budget priced category. Mine was perched a little higher off my desk on the edge of my monitor stand base, so that was a non issue for me.
The ‘correction curve’ of both treble and bass do not radically intrude into the midrange and is an excellent additional feature at this price point. Another great feature of this particular headphone amp is that it’s super easy to use. Simply rotate the knob to adjust the volume. You can press and hold the same knob to power the machine on or off. Giving the knob a short press allows you to switch between the setting menus for you to adjust features to suit your needs. This also allows you to switch between input and output ports. Let’s talk about one last negative before moving to the positives, getting all the bad news out of the way at once. In the case of planar magnetic headphones, at least the ones I have on hand, the K5 Pro does struggle. It is to be expected as it is powered by USB and I doubt that there is much in the way of current going on, but as soon as things like the HE400se are pushed with some strong and fast bass, you can tell that this little amp is struggling to keep up. I think one of the main factors for this evaluation is that the K5 Pro appears to be on the leaner side of neutral, with upper mids being slightly more forward and bass slightly reduced compared to other amps I own. Of course this evaluation only takes into consideration the units performance when no tone control is applied. So now on to the good. The performance of this little device is actually quite good. The sound signature seems to be neutral but without being too harsh, with a slight smoothness to the overall sound. With the dials set to the center position, I find the sound to be enjoyable, making things just have that little hint of warmth.
How We Picked
Another handy feature of this particular headphone amp is that it can also be used with speakers to boost sound quality. So if you want to boost the quality of your sound when watching your favorite movies and shows, or even when you’re playing your favorite games. This makes it the perfect fit for you if you want to use your new amp to boost several devices in your home. The Behringer Microamp HA400 is an excellent budget friendly option. This headphone amp features 4 stereo channels which can be controlled independently from each other. This is the kind of feature that would prevent people from spending and spending on many different headphones for every different album, genre and video game. Instead you just need to dial in your preferred tone setting, or adjust as you go, without having to reach for a different headphone for every occasion.
edit: I know for a fact it's the poor dac chip or implementation in the Q4, I used the pre outs on it into a few amps and it was just...... well it wasn't good at all. The amp might be fine but the dac is terrible. You may also want to consider how many output sections the headphone amp has. Depending on what you need to use your new headphone amp for, you may need to have output to several different sets of headphones or even speakers as well. A headphone amp that allows you to control the output to these different channels will be a handy feature to have. Sound control Moving around to the front, again from left to right, we find a 3.5mm TRS headphone output, a 3.5mm TRS microphone input, a bass knob, a treble knob and a volume knob that is also a push button. Above the 3.5mm input/output, we have a small row of (blue) LEDs that show which input is selected. As to why this is actually happening only in Spotify I'm uncertain and would have to take wild guesses. I would HIGHLY recommend trying to get the budget for a Schiit Fulla or Fiio K3, that or just run onboard audio, it's far superior. The K5 pro come in a good size box so I was surprised to see how small this gaming Amp was, look wise its very attractive gun metal finish with silver knobs. The device is well made and solid. it has more than adequate IO and the Bass and Treble is appreciated as I love physical EQ. The device was powerful to drive my planar headphones and gentle enough to run my IEMs so I am impressed with that already.
The scariest thing about Apple’s announcement
Q4 has been welcomed by the majority of users since its listing, buy the best gaming DAC on a limited budget and bring you HiFi enjoyment. All in all, I think that the Fosi K5 Pro is a very interesting device for its price and, although it may not be outstanding just on the audio front, it offers a lot of options for those who are looking for a cheap, compact, all in one device for their desktop. You will need to use the supplied Micro-USB cable to power it; we recommend using the PC-USB port/5V power adapter. Installing the DAC was as simple as plug and play, however it will need a dedicated USB port for power. It will not turn on if it has to compete for power through a passive USB hub. To turn the device on, the volume knob must be pressed and held for a few seconds and the the blue light above USB will light up to show the device is powered on and in USB input mode. The device always turns on in USB mode, independently of which input was selected before turning off.
Great Deal
