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

### ⭐⭐⭐⭐⭐ Review
*by J***T on 8 June 2017*

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.
