Nobsound Mini Bluetooth 5.0 Power Amplifier, Stereo Hi-Fi Digital Amp 2.0 Channel 50W×2 with AUX/USB/Bluetooth Input, Wireless Audio Receiver, PC Sound Card with Power Supply (Black)

I am somewhat of an audio enthusiast and let me start by saying that this is one incredible and powerful little amp. I've recently completed a rebuild of some Polk Audio 6.5" outdoor speakers and bought this amplifier to power them. Let me tell you, the sound level is truly amazing. This amp really has some muscle and the sound quality is quite good. I did, however, have a slight issue and need to apologize to Douk Audio. I had a replacement unit sent to me due to Bluetooth audio dropouts and severe distortion. I thought I had a defective unit, but the replacement had the same problem. Come to find out, the problem is with my iphone 6. The iOS was recently updated to 10.3.2 and it ruined the phone's Bluetooth connectivity when connected via wifi. All of my Bluetooth devices now have audio playback issues. The Nobsound's Bluetooth function does work perfectly with my other tablets and wife's iphone 6 which has iOS 10.2. The build quality seems pretty solid and I do like the fact that it accepts banana plugs. So far, the longest continuous playback has been about 1.5 hours and the amp only has gotten moderately warm playing at mid to low volume. I will be putting it through the paces soon. I plan on taking it to the beach along with my outdoor Polks that I previously mentioned. I'll be using a 12ah SLA battery with a 150W inverter for power. I've tested the set up and it works pretty well. I estimate the battery should last about 6hours using the supplied 5A power pack and pushing the amp below 50% volume. The beach will definitely be rockin' when I show up....ha!. Seriously though, in my opinion, having a set up like this makes a portable Bluetooth speaker obsolete. This is like having your home stereo with you anywhere you go, EXTREMELY loud with clear quality sound. I don't normally write reviews, but after seeing the other lack luster and not so good reviews, I had to chime in. I am thoroughly impressed and will highly recommend this Nobsound to anyone looking to power an extra set of speakers. I will definitely purchase another whenever this one goes out.

Perfect for my sim rig using Simhub. Identified it automatically and set up was plug and play. Great for a pair of shakers in your sim rig. I will say, dont get their shaker, get the Dayton Audio or the Aurasound instead. I HIGHLY recommend the Aurasound for a little more money, its an amazing shaker. I tested all three and that was significantly better for a little more money.

I’ve got three different amps on my sim rig running various bass shakers, and this one’s been a pleasant surprise. It’s powering two BST-2s and while it doesn’t hit as hard as some of my other amps, it delivers enough punch to feel immersive without being overwhelming. Setup was quick and easy—it even comes with an AUX cable, RCA cables, and a power supply, so you’re ready to go right out of the box. A few design notes: • The green front LED is very bright—noticeable in a dark room. • The front is white which doesn't really 'go' with most audio gear. • AUX input is on the front, which makes clean cable routing tricky. • The volume knob is oversized and has very little resistance—it works fine but feels a bit excessive. Still, performance is solid and reliable. Great value and a clean, simple option for tactile feedback in a sim setup.

This Nobsound Mini Bluetooth 5.0 Power Amplifier works for what we needed - which was a way to transmit signals to our outdoor speakers. Previously, the unpowered outdoor speakers had been connected to a head unit in the house and was able to be controlled via a remote. Alas, that head unit bit the dust and technology has moved on so most music is now digital (as opposed to the CD's we were using). The amplifier from the speaker manufacturer was exceeding expensive, even with a discount, so I found this unit. The item comes well packaged and has the appropriate connectors for whichever input you would like to use. This unit works and is able to accept bluetooth music from my phone (and, presumably, a tablet) as well as my PC (where most music resides). I saw no reason to test the other inputs, but I'm sure they are fine. This amplifier will return music to our spring evenings outdoors. There are a few annoyances, however. I think most have been addressed by others, but here is my take. First, the instructions are just not very good. When I opened the package and saw no markings or instructions about the bluetooth, I thought it wasn't included. Fortunately, I re-read the description and verified that it was. Checking my phone, I saw the device and all was good from there. Secondly, the volume control is odd; it can be adjusted in two places, either the source (phone/PC) or at the amp via the knob. I think I'll be selecting a set volume on the amp and let the source determine the volume level (usually the phone, because the PC and amp are located upstairs). Finally, and I don't know if this is something that can be controlled, but I left the amp connected to the PC and all sounds were transmitted - even though the music player was closed. So, various beeps and tones were broadcast to my neighborhood. I solved that by turning the amp off. Summary - good value amp that accepts bluetooth signals for my outdoor speakers. Has a few quirks, but I'd recommend it to others.

This worked perfectly with built in house speakers, easy to install and use, very powerful too

A joke amp. It is a fraction of the power advertised

Tenía guardadas unas bocinas de un teatro en casa Logitech Z906 que se me dañó y que me daba mucho pesar deshacerme de ellas porque me parecen muy buenas, investigando di con este pequeño aparato y después de leer y ver videos en YouTube decidí comprarlo, la verdad me impresionó por varias razones, lo mas obvio es su tamaño (en general casi todos los amplificadores de este tipo son grandes y feos) lo tenía pensado como sistema de sonido para mi sala y es muuuy discreto, la segunda razón es la facilidad y sencillez para conectarlo y configurarlo, lo haces literalmente en 3 min y por ultimo su potencia es muy buena tal vez le hace falta un poco de bajos pero por el precio tan bajo tengo un sistema de sonido bluetooth e inteligente (ahorita explico esta parte) decente y puedo seguir utilizando mis bocinas. Bueno ahora esta la parte de hacerlas inteligentes, me gusto tanto el sistema que quise ir un poco mas alla y sacarle mas jugo, pues descubrí como conectarlas a un chrome nest y ahora las instrucciones de reproducción que le doy a mi asistente personal se reproduce en mis bocinas a través de bluetooth, simplemente increíble para unas bocinas que estuve a punto de tirar literalmente hablando, así que ahora tengo un sistema de sonido de buena calidad y es smart, no puedo pedir mas Compraré otro para las otras bocinas que tengo del mismo teatro en casa y las pondré en mi oficina, me tiene encantado.

Not working and not powering on at all

Lo uso a donde voy..

El mini es perfecto, cómodo, y sinceramente es mucho mejor de lo que esperaba, le quitó una estrella porque el Bluetooth se desconecta seguido pero con cable como lo muestro en la foto funciona perfectamente! Super recomendado.
