    • This Bluetooth amp is AMAZING
I just completed a 12x16 gazebo and I wanted to install an easy/no hassle sound system in it, and I found the FOSI line of products here on the Zon – to be frank, I actually tried a couple of them until I settled on this one – why FOSI? - amazingly small, yet powerful enough to not only fill my gazebo with zero distortion perfect stereo music, but when turned up, my entire back yard - fantastic value for the money – sounds as good as my living room receiver wired to outdoor Bose speakers on the side of my house - it pairs without any problems, to mine, or my guest’s smart phone music - this model has RCA inputs too, for when I next get an outdoor TV, I can route the TV sound through it and into my corner beam mounted speakers** You should note that all of the above was true with the other models I originally purchased, except for filling the entire backyard with music, and this particular model had the most watts per output channel, for my requirements, so I settle on this one I have to say, for Bluetooth, I am amazed at just how good and clear they sound – I put my phone and the amp at 95% power level, and NO DISTORTION AT ALL – AMAZING All my friends who have seen it, luv it too (and may have also purchased some other Fosi model, as they asked for links what I bought) My 2 cents – if you are looking for a relatively inexpensive way to get sounds from your Bluetooth device (or via RCA jacks), any of these Fosi models will do the trick – just shop for your specific requirements and I am sure there will be a model for you ** I have had Bose outdoor speakers for probably 12+ years now, and I can vouch for them as the still work, with only some distortion now (I keep them up all year on the side of my house and only cover them in the winter) – for the gazebo, I wanted something more lightweight (the Bose are heavy), since I mounted them on my corner roof beams, and decided to try the “Yamaha NS-AW294BL Indoor/Outdoor 2-Way Speakers”, also sold here on the Zon, based upon the price and customer review/rating they have – well, I think they are a perfect match for any of these Bluetooth amps, especially this one, as they are also AMAZING As you can tell above I am EXTREMELY happy with my new sound system . . . FYI, I am just a boomer audiophile guy who likes to listen to Pinkish ‘o Floydish really loud in his backyard Hope this helps someone ... show more

    • good little amp, awesome bluetooth connectivity
spartan features, no fm tuner, no reverb, no sd card adapter; however, does what i want it to do. it connects with my bluetooth device(s). others advertise 40+ foot reception range, that is completely false, this unit has reception at approximately 30 feet even through a dogear fence. paired with dual lu43pb speakers provides for solid acoustic system. simple, uncomplicated little poolside system. do i miss a remote?....nah, something else to keep track of or find at the bottom of the pool. set the volume at about 50% and control with phone volume. perfect, no....awesome, yes. ... show more

    • Good build and sound quality but could be better
It’s a good build and decent sound quality but it’s not as clear as it can be - also I t’s not as powerful as it could be. Could use upgraded op amps, better caps and bass - treble tone control bypass

    • Sounds incredible
Review Image by Matthew
Theo’s amplifier sounds incredible. I tested it out before gifting it to my dad for his old pair of speakers, and I was blown away. I can turn it all the way up and make it extremely loud. At max volume you would expect to hear noise on most amps, but not this one. The 95db signal to noise ratio really makes a difference. On top of that the 0.05% total harmonic distortion means it sounds better than any home audio system/amp that I own. Bluetooth works great, I am glad that it doesn’t make any sounds when a Bluetooth device connects or Bluetooth mode is activated. I am very impressed and happy with this product and I would happily buy it again for other projects. ... show more

    • Small Unit...AAMAZING sound
In the middle of building my outdoor kitchen and had two speakers that were not very loud. I installed the BL20C 320 and it is absolutely great! It's simple, small and fits the bill for filling the backyard with great sound. The BT connect flawlessly without fuss or putting me though a pairing fight. This unit has a sub out which I plan to attached once I figure out what sub will be good for this outdoor location. If you are on the fence, get off of it and get this thing I promise you will not be disappointed. ... show more

    • As advertised! Better than I hoped for! Wow!
I don’t wrote many reviews, and was looking to replace a gigantic 25 year old 5.1 JVC Integrated Amp/AV stereo I use in the garage as a 2.1 stereo for streaming along with a cheap bluetooth receiver. Old and dusty and starting to be a little gitchy with volume and subwoofer issues but plenty of power for to fill the garage with sound. I looked around a lot and must have put dozens of items in my cart and taken them out over the last year, including this one. Made on offer for something else on a different place and got countered so i had 48 hours to accept. It was twice the price of this. Bought this on a whim with next day delivery and a 5% discount, thinking i could try this if i didn’t like iti could still accept the other deal. Tried it out last night and wow! Very loud, excellent controls, and oh so small! Not audiophile, but very clean sounding, bright mids and hoghs and loud boomy base from my old powered kilpsch 10 inch sub. Makes me thing the glitches on my old receiver included the subwoofer out port! Perfect for my garage. Id say a little light on the mid bass, but that could be my setup with bookshelf speakers (polk t15, about 10 years old). Very satisfied! Not sure about longevity, but no reason to worry, just haven’t had them long. Everything seems like a quality build, if a little basic. Streams bluetooth from my phone well. ... show more
