This mini-amplifier from Fosi Audio Packs quite a punch, relative to its size, especially with the subwoofer preout. Excellent value for money, sturdy build quality and outstanding performance. I'm using the ZA3 to power my rear bookshelf speakers in a 5.1 configuration-- Main Anthem power amp for my fronts and center, ZA3 for the rear through the Anthem preamplifier--Great synergy, Great Buy, God for It!

I bought one ZA3 and I felt both happy and sad - I had avoided class D like the plague till date for obvious reasons and I felt like a fool for the same. I was impressed with the clarity straight out of the box and ended up ordering one more box to use each as a mini lock for my system. The low end is good and quite defined, the upper registers definitely are good, but could be better. May try and get a couple of sparkos op amps and see if it improves it. For the money paid for biamping, it definitely sounds like a great option in lieu of AB class amps. It costs just 50% of entry level amps, but definitely offer more power and quality as compared to those amps. The QC control and build quality seems solid. And the foot print it occupies is rather small. I can look at this amps performance and say confidently that cheaper non hypex class D is here now and it’s here to stay.

1999 is nothing the engineering is perfect of this IEM,,,
Amzing product
Love the way it sounds rich in every range perfect for beginners but if you're not a bass head go for non bass varient.
This is my first ever IEM that I purchased after research of couple of months. And I can say that this was a good decision on my end. Cable is good. Buds look stylish. Comes with a small carry pouch and 6 pairs of ear tips. Sound quality is awesome. Love the instrument separation. Customisable EQ gives them versatility. You can actually experience how other IEM sound just be playing around with the EQ.
Actually, l'm new to this IEM world. Such an amazing product. If you are new to iem just as me, I would highly recommend his product to try out. The OG. There are 16 types of tuning options to play around and explore your favourite music in a new way and the build quality is also pretty good. Overall a nice product 👍.
Good sound
5/5 Mids and Highs
5/5 Well balanced Bass, doesn't overpower the music
5/5 Design look premium and classy
They are quiet heavy and huge
Its my first time buying an iem and it sounds sooo good the design is good the wire can be improve, the bass is somewhat missing and the app has some glitches regarding equalizer. Otherwise this iem is better than my tws. I really like it.
Good
They sound just amazing, I would say that the app a little rough to use. I can vouch they sound amazing. better than most of the tws which are out there in the market. Also, the Online dsp, gives a little edge it you want to tune them, and you can also upload your on DSP. Overall at this price point, It' a 10 on 10 deal.
Great place to shop for all audio requirements. Quick service and product as described. Will recommend it to 3

Really a great product for the price offered using thebuds for the first time and it has exceeded my expectations. The sound is more balancednot a thumping bass but withclear vocals, treble and and a surrounding bass. Also there's someissue in connectivity which I faced at firstbut saw a tutorialon resolving the issue online.
everything is great but would have been even better if it had a mic
Awesome case, providing safety
