Solid built and compact form factor. Works well as a Laptop/PC seamlessly, I had some issues connecting with my android phone. But HPZ team was very helpful in making it work, turned out the USB-C to USB-C cable was the fault. Only thing required was to turn on the OTG. The best part was HPZ were ready to even make a return and check the connection with Phone and if the unit is faulty they also committed to replace it with a new one. Very happy with the business ethics of HPZ, there aren't much online retailers out there who are this much committed to customer's requirements. Great job in setting up the team and the business eithcs, Keep it up!!!

Coming back to Fiio K3, overall quite satisfied with the performance. The main reason for buying this was to decode the Hi-Res lossless/Lossless format from Apple since the phone DAC specially in android phones does not do any justice to Hi res audio formats. So this is a must accessory for audiophiles.
My main use case is to connect my phone with my Marantz AVR and listen to Hi-Res music over my stereo setup comprising of Sonodyne 3165 tower and a Sonodyne 1010 Sub.
The initial impressions with my Audio Technica M50x I felt the bass to be on the lower side (This could be a personal preference) with bass gain set to off, with bass gain enabled the output is rather artificial, it makes almost all the frequencies little lower thus increasing the bass response. But with my AVR setup it was rather more impressive. Main reason for that is FiiO has 2 digital S/PDIF output (Coaxial and Optical) port which sends out a digital signal as it is from the USB input source. So the actual digital to analogue conversion was happening in my AVR. All the frequencies were more pronounced with Apple HiRes lossless format compared to Amazon music when streamed via DSD with 256 kpbs AAC format.
Best for people who want a Laptop/PC DAC who want to enjoy music/movies. But with mobile phone although it works perfectly well but it drains too much of the phone battery which is not very practical for heavy use case. For phone usage better to use battery powered DACs or external power DAC. What makes FiiO K3 unique are its output ports, it not only has 2 digital out ports but also a headphone AMP with one balanced and an unbalanced headphone output.

As you can read in title " Great Little Champ "!
I wanted DAC/AMP for my desktop and laptop use. This is very potable DAC/AMP, by the way I am using it like a desktop AMP with Sennheiser HD 599 SE. I works great. You can hear every detail in music. Usually I listen on Spotify but to explore this Dac more I purchased Apple Music subscription and DAMN !!!! This AMP - Headphones combo will blow your mind.

Lows: Bass is there. But not very boomy but it's there you will notice it. And its very clear and punchy.

Mids: Vocals are clear AF, with this open back headphones you can really hear those little crackings in singers voice and drums in songs like "Boulevard of brocken dream" are very realistic and really hits you.

Highs: High are there but will not hurt your ears. I think highs are toned down in this DAC and also because of HD 599 SE highs are not so concentrated. But for me that's an advantage.

Sound Stage: It's great! Instruments seperation is very good. I used it for gaming ( CSGO, PUBG, Valorant, GTA Online) it perfomed very well, I never heard gunshots so clearly in my whole gaming career and I could accurately identify enemy position in PUBG.

Compatibility: I was concerned about USB 2 compatibilty with MacOs and Android but it works like Plug and Play. On Windows 10/11 also it does not require any drivers because in latest updates of windows Microsoft given USB 2 audio drivers built-in. So no drivers required for Computers and Mobile phones. But I connected this with My Android TV which has Android 9 Pie, that doesn't have USB 2 drivers, so I have to switch it to USB 1 mode. I haven't tested its Balanced output which is a big feature of this Dac because I don't have 2.5mm connector.

Overall it's a great experience with New FIIO K3 DAC/AMP.

FiiO - New K3

This is a great AMP/DAC that is super compact. You can use it normally on your desk or carry it around to use with you Android/Apple device. Works wonders for a laptop or tablet, which have trouble running 50Ω-150Ω impedance headphones.
Bass boost feature is also done in good taste, it doesn't crush the mids or highs. It just gives a sizable bump to the bass without compromising the other frequencies. You will a good set of cans to pair with these however. I'd recommend the Sennheiser HD599 (For Open-Back goodness) , Hifiman HE400SE (For Planar Magnetic Bass) or a Beyerdynamic - DT770 PRO (For isolated Closed-Back). These are all in 10k-15k inr range and pair well with the K3.

Pretty good for beginners

A very compact build, with very clean and natural audio output.
Used it with Beyerdynamic DT 700 PRO X and Audio-Technica Ath-E40 delivers excellent sound quality.
The bass boost gives a nice and clear bass with no distortion.
Thank you Headphone zone for the faster dilevery
