BITIWEND Mini Bluetooth Amplifier, HiFi Audio Power Amplifier, Stereo Digital Amp 2.0 Channel 100W with AUX/USB/Bluetooth Input, Speaker/Earphone Output

This really has no right to be this decent - it's a tiny little thing, which is perfect for me as it is going to be tucked away to power a pair old old floorstanding speakers that were otherwise redundant after I upgraded my speakers in our living room. They've sat under my bed for ages purely because I didn't want to try and fit an amp into my already cluttered spare room where the PC is situated, but this thing is so small it takes up no space at all.Of course it would be pointless if it was small but sounded rubbish, but I'm pleased to report that it punches way above it's weight (and size!). Is it a match for my amp downstairs? Of course not, but it's not designed to be. What it is though is a bargain for £30 or so, and a neat way to breath life into old speakers that were literally gathering dust otherwise. All the music I've thrown at it has sounded good, either via my old Eltax speakers (which were never amazing but more than adequate for use with my PC) or via the headphone out socket and my AKGs.Setup is dead easy for both connecting it to a PC (via USB where it appears as an external audio device), or if you are using aux or bluetooth for a phone etc. I'd suggest getting some banana plugs to make life easier connecting your speakers to the binding posts but it's not essential. The manual that comes with it is small and concise but does the job as it's not exactly complex to use.For the price this is a great little (very little - I'm still struck at home small it is compared to a normal amp) amp that offers a really decent sound for the relatively meagre asking price.If this review has been useful please hit the helpful button - cheers!

Audio is ok. Bass is not very strong. It is a solution to a no sound problem and works reasonably well. If You are not wanting to buy an amplifier or similar, and you want reasonable audio in a tiny footprint then it is good value. This is why I bought it and it serves my PC well.As an aside I can’t understand the designs of this device and feel it lets it down. The inputs are on the front instead of the back. It makes it impossible to forget you have a device with wires coming out of it on your desktop. Headphones port is understandable but both source inputs are front facing meaning it can never look tidy.For a small device this is its biggest let down.

Only had this little amp a few hours, driving my elac bass and satellite speakers. Got to SAY BRILLIANT.so tiny dont know how you do it. So many++++++ s and good all round punchy sound.Its bluetooth so you can easily connect to mobile phones and laptops and Amazon echo it can be used as a sound card in laptops or pc good replacement for an old crackly 3.5mm audio plug,also an analogue input and headphone out.It accepts banana plugs so no messing about easy and straightforward to set upBig jog wheel controls volume and switching between inputs and it gets just warm to the touch.No remote but not a problem.Its 12v/24, the 13.5v power supply supplied has a faint hum, using a 19v power supply stopped the hum an increased the max volume a bit higher with no distortion:))I've read the reviews and no one mentions using it in a vehicle? 12v for cars and 24v for lorry's would work:)), as the bluetooth auto reconnects, no messing about start car switch bluetooth on phone, off you goJust to add the bluetooth has a decent range,its been on 24 hours now,no drop outs/ cut ins .still no heat build up:)To sum up if you've got an old set of speakers,this amp will revive them:)) and dont forget using in a vehicle.

I used to have an old hifi behind my PC monitor, just so I could have reasonable sound when watching movies or playing games. This allowed me to throw away all but the speakers, and gain better functionality along the way.It connects as a USB audio device and is plug and play, fasten some speakers to the screw terminals (or use banana plugs), plug in the small power supply and you are ready to go- no hassle. It also allows connecting via bluetooth, so I can stream an audiobook/podcast etc from my phone, as well as an AUX connection. A front mounted headphone socket keeps my wife happy in the evening too :) .Sound quality is as good as can be expected for somthing this small- it is not going to compete with your home theatre, but it still impressive for its size and suprisingly powerful. Even comes with a range of cables for different connection options. Great piece of kit.

At this price point, I didn't expect too much. To be fair the amplifier circuit is pretty good with plenty of grunt and good stereo separation when run off an external analogue input via the Aux connection. It drives smaller speakers and headphones, particularly the latter, very well indeed, as loud as anyone would want to go; the range is quite well controlled provided you have a good quality source signal (I was feeding from an Arylic S10 - now, that is £50 well spent).However, there's definitely a fair bit of background hiss detectable in quieter passages - if you like the retro sound of cassette tapes this could be for you! Unfortunately, hiss is quite intrusive on headphones during quiet spells, and as others have noted there are minor clicks and pops when working the volume dial, but I think I could live with that if that was the only failing.As for plugging in a streaming source, such as PC or phone or Raspberry Pi, for playback via the mini USB port/ internal DAC, for me that was just NO! Very thin decoding, little in the way of bass, and the treble got harsh quickly, nowhere near the control it had compared to the external analogue source. Really the USB connect is not much use, and seemed no better than an internal DAC on a PC or phone, hence a bit pointless.Bluetooth is basic SBC and again the reconstituted BT sound via the internal DAC circuitry has little to offer other than convenience.Overall , I think it's not really for me, shame because at the heart of it the amplifier circuit is not half bad.
