I can't express how much I love this thing. I had an old 2.1 set of Boston Acoustics Micro 80 passive speakers with the sub and one day I got a new MAC Book Pro and docking station and so I was looking for new speakers when I came across this little guy. Not only did I NOT need to buy new active computer speakers, but my old BA's still sound incredible. And I wasn't even looking for anything that powerful but I am so happy I found this perfect solution. It drives my passive speakers so well. Unbelievable sound from such a small package. I am so so happy! Thank you!

Gra poprawnie. Lekko góra przesiada, ale można skorygować potencjometrami.Co by nie napisać niestety tylko SBC.

Geen ruis, heel uitgebalanceerd en helder geluid. Mooi compact . Bluetooth zou uitschakelbaar moeten zijn . Als ik mijn audiocast erop aansluit moet ik op al mijn apparaten de Bluetooth uitzetten om het te kunnen gebruiken

Easy to connect via bluetooth. Amp works great and has plenty of volume for me. Very small size. I like that the connection switches to bluetooth automatically and back to AUX when you disconnect bluetooth.

Using it together With hifispeakers in my workshop!

Rapporto qualità prezzo incredibili. Nella scatola c'erano inclusi già 8 connettori. Ottima qualità dei potenziometri. L'amplificatore è veramente piccolo ma ha una qualità e potenza audio impressionante (sto parlando di potenza idonea ad un salotto o camera da letto) se accoppiato a casse acustiche di qualità (ora in uso con delle vecchie JBL). Buona la connessione Bluetooth. L'ho trovato in offerta come "seconda mano" a 50 euro...un vero affare.

wanted something with a small footprint with Bass and Treble and can use banana plugs and this was it! Very impressed with the power of this small device. I'm powering a pair of Micca OoO speakers which is connected to my PC and this is the perfect pairing. This can get pretty loud with no distortion and can easily fill a small to medium sized room. Build quality is good. All metal housing. Not super heavy but doesn't feel cheap either. There's rubber feet on the bottom which is nice. Powering on the unit is done by the main volume knob. Turn it all the way left and there is a solid click when powering off/on. The main unit displays a red led when using AUX and I think a blue led when using Bluetooth - haven't tried it yet. The power brick also has a blue led light on it. My only concern was that I noticed my speakers cutting in and out periodically and thought I got a defective unit until I realized that the housing on my banana connecters were touching each other. This was easily remedied using a small piece of rubber that I placed in between the connectors so they do not touch. After doing that, the sound was crystal clear. Would definitely recommend this.

As an amplifier, this little guy is great! Surprisingly clean sound and powerful to make even moderately efficient speakers sing. However, there is one glaring issue...The Bluetooth! It works with an overly simple Bluetooth configuration where there's no switch, it just accepts a Bluetooth connection and stays that way until it looses Bluetooth signal. Not very elegant, but functional in most cases. When you have more than one, it's annoying to figure out which is which. But connectivity and range are descent enough. Nothing to take a star away for. So what's the problem?Sound Quality over Bluetooth. Despite being advertised as Bluetooth 5.0, it sounds like a Bluetooth 3.0 or earlier device. Very compressed/crackly sounding top end is introduced. It's not loud, but it's there, and it very discernable in critical listening. Sound quality is FAR better when a computer, tablet, or phone is connected directly with an RCA.So if RCA performance is the priority, this is fine. BT is usable in a crunch, but you don't want it to be your main use case. I wanted this in my garage, and it became very noticble at higher volumes. At first I thought it was the amp running out of juice, but no issue over RCA. Tried multiple BT devices, same problem.Now I have an old Onkyo receiver and a separate $25 BT station from Amazon, and this sounds WAY better in the Garage, but takes FAR more space and uses more power. But I would have been satisfied as is if the BT quality were better.For a desktop computer speaker setup, or a stationary small entertainment area with TV, this is fantastic! We have one in my Son's room with some bookshelf speakers, and it's perfect. He's 4, and he can use it as just an amp no problem.Please, Fosi, get the BT SQ up to spec, and you'll have the best little amp package on the market.If this were a more expensive unit, I'd only give it 3 stars, but the bang for the buck is great. I especially like it with Bookshelf Size Speakers, just make sure there fairly efficient, unless they're really only used for quieter applications.

What a great product.I took a couple of months to finally get around to researching the options for a wireless amp that I could mate to my old AIWA twin 40 watt speakers which I retained after throwing out the ancient triple CD player deck they came with.I first came across the Fosi (blue) mini amp which didn't have bluetooth but after a little more research found this unit which is only 10 bucks more ... as I wanted to be able to connect my phone or laptop quickly with no wires this was the best option.The device came quickly several days ahead of the original delivery estimate so that was cool, I unboxed it. Great quality you can feel the sturdiness of the metal, well crafted. The toggle switch is solid, the volume dial is smooth...though if it had a larger diameter it would allow some more volume control fidelity.Getting it up and working was a literal 4 minute affair.I connected the speakers using the twist connectors on the back, I plugged the adapter into the amp then into the wall (as they insist you do).Then powered it on...as described the blue tooth was broadcasting and my phone connected, an audible bump attends each connection disconnection. I set up the device as a trusted blue tooth on my phone which would allow it to auto connect when my phone is in proximity so I don't have to actively connect it so long as my blue tooth is on my phone which is super convenient.I started playing various audio, I played some high quality mp3's and it was great to hear those speakers come to life for the first time with a high quality amp that could push them to their limits (this amp is 50w per channel so I need to be careful). I also played some youtube videos which sound so much better coming through full powerful speakers (which I have on the ground so there is the bass effect).Edit:Since connecting my phone I also have mated the device with no issues with my laptop...as I am often at home with the laptop it serves as a better streaming source to the device ...I could in theory also use my nexus 9 for this.The sound coming from movies and videos played on youtube is rich and distinct, extremely happy with this as I am about to purchase a large HD screen that I will also be casting sound to this speaker set up through.Needless to say they just work, really great I am considering buying another one and a pair of new speakers just to use in my other room, I considered at first getting a Google chrome Audio because it allows connection through wifi but I would still have had to buy a mini amp to drive these speakers so decided to get this since blue tooth has pretty good range and often better quality than wifi (particularly as quality doesn't degrade with device connections as with this it is a dedicated connection) and like I said this version of the mini amp was only 10 bucks more than the non blue tooth version.Highly recommended.
