BT10A Bluetooth 5.0 Stereo Audio Amplifier Receiver 2 Channel Class D Mini Hi-Fi Integrated Amp for Home Passive Speakers 50W x 2 TPA3116

What a great product. I took a couple of months to finally get around to researching the options for a wireless amp that I could mate to my old AIWA twin 40 watt speakers which I retained after throwing out the ancient triple CD player deck they came with. I first came across the Fosi (blue) mini amp which didn't have bluetooth but after a little more research found this unit which is only 10 bucks more ... as I wanted to be able to connect my phone or laptop quickly with no wires this was the best option. The device came quickly several days ahead of the original delivery estimate so that was cool, I unboxed it. Great quality you can feel the sturdiness of the metal, well crafted. The toggle switch is solid, the volume dial is smooth...though if it had a larger diameter it would allow some more volume control fidelity. Getting it up and working was a literal 4 minute affair. I connected the speakers using the twist connectors on the back, I plugged the adapter into the amp then into the wall (as they insist you do). Then powered it on...as described the blue tooth was broadcasting and my phone connected, an audible bump attends each connection disconnection. I set up the device as a trusted blue tooth on my phone which would allow it to auto connect when my phone is in proximity so I don't have to actively connect it so long as my blue tooth is on my phone which is super convenient. I started playing various audio, I played some high quality mp3's and it was great to hear those speakers come to life for the first time with a high quality amp that could push them to their limits (this amp is 50w per channel so I need to be careful). I also played some youtube videos which sound so much better coming through full powerful speakers (which I have on the ground so there is the bass effect). Edit: Since connecting my phone I also have mated the device with no issues with my laptop...as I am often at home with the laptop it serves as a better streaming source to the device ...I could in theory also use my nexus 9 for this. The sound coming from movies and videos played on youtube is rich and distinct, extremely happy with this as I am about to purchase a large HD screen that I will also be casting sound to this speaker set up through. Needless to say they just work, really great I am considering buying another one and a pair of new speakers just to use in my other room, I considered at first getting a Google chrome Audio because it allows connection through wifi but I would still have had to buy a mini amp to drive these speakers so decided to get this since blue tooth has pretty good range and often better quality than wifi (particularly as quality doesn't degrade with device connections as with this it is a dedicated connection) and like I said this version of the mini amp was only 10 bucks more than the non blue tooth version. Highly recommended.

I was looking to build a budget-friendly stereo system for my living room, and after doing some research, I decided to pair the Fosi Audio BT10A with my classic DBX speakers. This little amp is a fantastic starting point for anyone looking to get into a dedicated hi-fi setup without spending a fortune. The setup was incredibly easy. I simply connected the speaker wire to the binding posts and plugged it in. The sound it produces is clear, and it drives my DBX speakers surprisingly well. The 50W per channel is more than enough to fill the room, and the sound is rich with no noticeable hum or hiss. I particularly appreciate the Bluetooth connectivity, which makes it super easy to stream music from my phone without any extra cables. It's dedicated Bass and Treble knobs are also really nice.

Very impressed by this little amp. Built pretty robust. Sounds very clear and Bluetooth functions well. I’m very impressed for the price. Driving two JBL 6.5 pendant speakers with ease.

As an amplifier, this little guy is great! Surprisingly clean sound and powerful to make even moderately efficient speakers sing. However, there is one glaring issue... The Bluetooth! It works with an overly simple Bluetooth configuration where there's no switch, it just accepts a Bluetooth connection and stays that way until it looses Bluetooth signal. Not very elegant, but functional in most cases. When you have more than one, it's annoying to figure out which is which. But connectivity and range are descent enough. Nothing to take a star away for. So what's the problem? Sound Quality over Bluetooth. Despite being advertised as Bluetooth 5.0, it sounds like a Bluetooth 3.0 or earlier device. Very compressed/crackly sounding top end is introduced. It's not loud, but it's there, and it very discernable in critical listening. Sound quality is FAR better when a computer, tablet, or phone is connected directly with an RCA. So if RCA performance is the priority, this is fine. BT is usable in a crunch, but you don't want it to be your main use case. I wanted this in my garage, and it became very noticble at higher volumes. At first I thought it was the amp running out of juice, but no issue over RCA. Tried multiple BT devices, same problem. Now I have an old Onkyo receiver and a separate $25 BT station from Amazon, and this sounds WAY better in the Garage, but takes FAR more space and uses more power. But I would have been satisfied as is if the BT quality were better. For a desktop computer speaker setup, or a stationary small entertainment area with TV, this is fantastic! We have one in my Son's room with some bookshelf speakers, and it's perfect. He's 4, and he can use it as just an amp no problem. Please, Fosi, get the BT SQ up to spec, and you'll have the best little amp package on the market. If this were a more expensive unit, I'd only give it 3 stars, but the bang for the buck is great. I especially like it with Bookshelf Size Speakers, just make sure there fairly efficient, unless they're really only used for quieter applications.

I recently picked up the Fosi BT10A, and wow—this little amp completely exceeded my expectations! I dusted off a pair of older Klipsch R-15M bookshelf speakers from the basement and hooked them up to my PC. Since they’re passive speakers, I needed an amp, and this one was perfect—especially with the 3.5mm input for easy PC connection. Setup took just minutes: plug it in, connect the speakers and cable, and you’re ready to go. The sound is huge—clear, clean, and powerful enough to drive the R-15Ms beautifully. For such a compact and affordable amp, this thing is an absolute gem. Highly recommend!

Our house has built in ceiling speakers in the outdoor patio. Previously, I had them hooked up to the indoor A/V Receiver as a second speaker zone. I found that frustrating to use because the setup and recall was clumsy, so I rarely played them. Recently the 'mental light bulb' hit and I thought maybe somebody manufactures a small amplifier that I could dedicate just for these outside speakers. And sure enough I found the Fosi Audio BT10A. Works great! I use the Bluetooth for connecting either my iPad or iPhone for the audio playback control. Bluetooth connectivity is easy and works through my house walls to the patio area. Price-wise it didn't break the budget. I don't wish to compare the audio quality with an in-home quality audio listening system environment as that is not its purpose for me. I just want some background music while relaxing outside on the patio. The system does sound good though. The size surprised me as it is a small unit. The size is actually perfect for what I was looking for. It's a nice feeling finding and purchasing an item that fits your wishes really well. Recommended.

Works perfectly. Everything connects right to it.

I just fired this little guy up an hour ago. I've had a pair of older B&W 805s sitting silent for the last eight years, and they were going to go the way of Craaaagslist or use them. Had to be BT. Had to be affordable. And had to be able to drive these speakers. This is not my first Class D amp. I bought a Waaadia about 8 years ago for use with these B&Ws. I sent it back. No muscle whatsoever. It was a $900 integrated amp. I had to eat a re-stocking charge. Fine. Now, for details. The BT connection was instantaneous. The sound quality? Amazing. These B&Ws used to be my "other" speakers. I was the proud owner of tube pre-amp, a pair of tube monoblocks feeding some very large Magnapan planar speakers, plus a couple of high end CD players and custom DACS. In short, I'm an audio junkie. But, all that big stuff had to go when we moved. It felt weird designing my new home around my audio system. Poof - it all went, except for the B&W and 1200 CDs. After a couple hours of playing I decided to crank it up. I set the amp at 50%, and pushed my BT signal at 50%, then 75, then 100%. That would be louder than I ever want for normal listening. No distortion, no digital hash. I played with the bass and treble. The base is set a tad "higher" than neutral. The treble needed to be pushed to about 70% to get the high end clarity I deemed necessary. Treble at neutral was a little muddy. Then, just for fun, I backed off by BT output to 50% and cranked up the Fosi to 90%. Then I started adding more BT gain. Whoa! No distortion that I can discern. Then I started running the volume control up and down in rapid succession. No hiss, no popping and no power lag when pushed at full load. Bottom line. It's worth every penny. I just happen to have another pair of unused speakers (little baby Bose 6 inch book shelf) and I see another Fosi in my future for the garage/shop/deck and maybe some custom straps/slings to make it portable. I don't regret having spent a lot of money on my old high end audio system. I don't regret downsizing to "normal" audio gear. I do kinda feel like I just stole something though. Amazing.
