    I was very impressed with the sound and performance of this little unit. I was also impressed with the Bluetooth distance I could use it away from the unit, which is about 15 metres or more. Love it.

    Shipped quickly and packaged well.
    Sound quality is great for the size, it doesnt quite have the punch of a full size stereo amp or receiver.
    But for normal listening its great, the quick treble bass adjustments are very handy for on the fly tuning. Using this on my desk with some good quality stereo speakers.
    Would recommend it.

    Considering the price and size of this amp, you will not believe the hifi quality sound it produces – crystal high frequencies, tight low end with strong mids. The bluetooth connectivity is great.

    I originally bought some expensive PC speakers to play my hi-res music from my MAC while I’m working. They were pants!! So I thought I’d look for a hi-fi solution. Worried about what I would get on a budget, I luckily found this amp along with a pair of entry level Wharfedale speakers. Reviews for this amp were extremely favourable so I bit the bullet. I am so glad I did.

    This is a PERFECT solution for what I needed. Hi-res hi-fi sound from my MAC. I think anyone who buys real hifi products would be extremely surprised at the performance from this little unit. It wouldn’t replace my full hi-fi amp but it is not far off.

    If you are on a budget and need sound from your MAC or PC, forget the range of ‘computer speakers’. Most of them are poor. Get this amp and some decent hi-fi speakers. You won’t regret it. I am stunned and over the moon with it!

    The amp is decently clean on sound and feels well made for the money. If you’re happy with low to smooth, averagely quiet listenings then this will suit fine. But if you want the full spectrum and more beef or a bit bolder yet smoother sound and, from time to time, at strong volumes then go for the NobsoundNS-15G PRO CSR867. I ordered both and did an A-B comparison with Q acoustic concept 20s(with stands) and the Monitor Audio Bronze 2.
    Most people will be fine with this amp to be honest but you can have that little bit more for £12 extra.

    Despite returning this amp, I have to give it 5 stars for value for money. If your only going to use the RCA input the sound is pretty good and filled a 14’ square room with ease.
    It was very quick to discover all my devices via Bluetooth.
    However for me the reproduction via Bluetooth was a disappointment (I tried iPod and Amazon prime music via both iPad and laptop) and reproduction was dull and lifeless. I accept that reproduction will never be as good at this price level, but the difference between the Bluetooth and the RCA Input was just too marked for me to live with.
    I was looking to spend far more on a new amplifier than this, but thought I would give it a try as it had such glowing reviews.
    So went for a Mission Cyrus one HD, yes it’s over 12 times the price, but Bluetooth reproduction is as good if not better than the RCA input of the Fosi.
    It would be very unfair to bad mouth this little amp, as if your just going to use the RCA Input this little fella punches well above its weight, just don’t expect the same quality of reproduction when using Bluetooth.
    Simon.

    The actual sound quality is very good and works well with my speakers.

    I am however annoyed and disappointed that the bluetooth no longer works. Something has caused this to stop broadcasting “Fosi Audio” and hence nothing can pair with it any more.

    Turing the device off and leaving it unplugged does nothing. There is not way to reset this, so it seems the bluetooth module has become faulty.

    Edit:

    Back to 5 starts, simply because I now have a new device sent to me by fosiaudio direct.
    The bluetooth is working perfectly now. It seems the previous batch may have had an innate fault that caused the issue of the bluetooth chip failing.

    Customer service is very good considering that although a replacement part was sent, I never received it but the CS rep investigated and sent out a new unit instead, which I received within 3 days.

    It did take 6 weeks to sort out though.

    I was dubious but this tiny amp does have a lot of power for it’s size. Was driving a pair of small Dynaudio 4ohm bookshelf speakers with no issue. Sound quality is ok, nothing amazing there but the built in EQ with bass and treble adjustment is handy.

    This compact little unit punches well above its weight. It is the easiest Bluetooth device I have to connect to and has awesome range. The sound is great. I can’t rate it highly enough, been using for over a year, hasn’t missed a beat. It powers a pair of older Sony bookshelf speakers in a high ceiling 120sqm shed and fills the area well. Love it!!

    Die Lieferung erfolgte sehr zügig und das Gerät war sehr solide verpackt.

    Der Verstärker macht einen wertigen Eindruck und ist äußerlich sauber verarbeitet.
    Mit seinen sehr kompakten Abmessungen ist er nahezu überall einsetzbar.

    Das Gerät ist Ruck-Zuck aufgebaut; die Lautsprecher und das mitgelieferte Netzteil gemäß der Anleitung verbinden und schon kann es los gehen.
    Meine Lautsprecher habe ich über Bananenstecker angekoppelt, man könnte aber auch die Drähte direkt über vorhandene Klemmstellen am Verstärker verbinden.

    Die Kopplung via Bluetooth funktionierte auf Anhieb.
    Die Reichweite und Verbindungsstabilität des Bluetooth haben mich vollkommen überzeugt! Trotz einer Wand und mehreren Metern Abstand kann die Verbindung problemlos aufgebaut werden und Musik konnte ich bisher unterbrechungsfrei von verschiedensten Orten aus abspielen.

    Über die 3 Drehregler können die Höhen, Bässe und die Lautstärke geregelt werden.
    Leider war bei mir zunächst kaum Bass vorhanden, auch auf maximaler Stufe.
    Nach Rücksprache mit dem Support von Fosi und gemeinsamer Fehlersuche wurde mir ein Ersatzgerät zur Verfügung gestellt und dieses funktioniert optimal. Höhen, Bass und Lautstärke sind in großen Bereichen regelbar und können so stufenlos individuell eingestellt werden.

    Der Support war wirklich super und innerhalb weniger Stunden hatte man konkrete Antworten und Problemlösungsvorschläge.

    Zusammenfassend kann ich diesen Verstärker wärmstens empfehlen und durch den sehr guten Support von Fosi ist gesichert, dass auch bei möglichen Problemen der Kunde am Ende komplett zufrieden ist.

    I was very surprised at the sound quality and build this small cheap amplifier.
    I was mainly getting this for a small pair of older B&W speakers (DM302), as I’m travelling a bit for work shortly (in the car) and wanted to take some music with me.
    It sounded so good with them, I tried in on my other speakers that I have at home – including large floor standing Linn and B&W speakers (I have a few different pairs of both).

    It was surprising good – the amp had no trouble driving a pair of B&W 603 or my older Linn Keilidth speakers. Sure, it didn’t have the same ‘oomph’ that my normal big amp has, but it was very listenable to at moderate volumes.

    The bluetooth quality is certainly lower than the audio quality from the rear plugs – but it varied from horrible (from an old phone) to reasonable from a modern device (ie my Microsoft surface pro).

    Other positives –
    1) there is no discernable hum or hiss when nothing is playing, even if you stick your ear right up to the speaker.
    2) there are no annoying pops or crackles through the speakers when you turn it on.
    3) there is a mechanical relay (you can hear it click) that swaps from bluetooth to the back panel input.
    4) pairing just works with a range of devices (I used a number of phones, plus windows tablets and laptops).
    5) The power supply it arrived with – in Australia – was a proper 240V one, not a 220V one. This is very useful for me as we quite often have over 250V at the socket..

    The only negative I could see was the lack of an optical input, but FOSI have other units that can do that.

    So yep, it and my dm302s, and a rca cable, are going travelling with me shortly. And when I get home it’s going to replace one of my older main amps…
