Amazing sound, powerful bass, clear highs

I love this amp. It works with a pair of 6-inch two-way bass reflex speakers sourced from a 100-watt Phillips All-in-One FM CD player. Incredible bass and brilliant clear highs. Plugged into the headphone jack of a 43" Sony TV so I can control the volume with the TV remote. The Bluetooth from my iPhone works well and sounds great too. I would give it 6 stars if I could. We'll see how long it lasts but so far I'm very satisfied. I've been using speakers in my bedroom, wall mounted in each corner

Pros
  • nice thing
Cons
  • weak kit

Exactly what I was hoping for.

I connected this amp to a pair of 4 inch bookshelf speakers on my desk, powered by a black Dragonfly DAC connected to my computer. Sounds great at near field volume for the job, but I've never had the volume dial read more than 8 o'clock. I know people who spend thousands on audio amps criticize them because those little ship's amps can sound good at low volume, but when the power output goes past 50% they fall apart. Maybe one day I'll take it home and test it out in my living room with myโ€ฆ

Pros
  • New to my collection
Cons
  • Good but not great

This little thing is cool

I had mixed expectations when I ordered the bluetooth version of this little amp. I have trusted Fosi to upgrade the amps with the new Bluetooth and it has not let me down. Bluetooth connected with no problems. The sound that comes here far exceeded my expectations. I wasn't sure how loud it would play, but more importantly I wasn't sure about the performance/sound quality. I hooked it up to an old set of Bose 101 outdoor speakers and it really made me smile. The first two songs were Man in the

Tiny bluetooth stereo amplifier with pretty good sound!

I needed a new amplifier for my garage speakers and decided on this tiny Class D amplifier. What it is: Stereo Class D amplifier with Bluetooth and AUX inputs. It is rated at 100 watts per channel. I'm not sure if that's correct or not. I bet you don't. Why I like it: I needed a small amp with bluetooth and aux inputs and bass and treble controls. I've hooked up a pair of Philips two-way bookshelf speakers and my iPhone and the sound sounds pretty good. The signal-to-noise ratio could beโ€ฆ

More power but broken bluetooth

I used the fosi 50x2 and decided I needed a little more power so I upgraded to the 100x2 version with bluetooth. Power 19V. Both the 50x2 and 100x2 will spark if you plug in the back panel, which is scary. If you plug it in first and then plug the power adapter into an outlet, there will be no spark. The 100x2 has separate controls for bass, treble and volume. With 50x2 there is only one volume control. 100x2 has Bluetooth. When I connect my iPhone xs to it via Bluetooth and play through theโ€ฆ

A few minor changes but overall a very decent amp

When this thing came out I thought it was a small piece of junk. Its size is approximately the equivalent of 4 packs of cigarettes. Based on the other reviews I went ahead and hooked it up, glad I did! Worked with two Paradigm outdoor speakers. Lots of sound, no problems. I adjusted the treble a bit and turned the volume up to about 1/2 to 5/8 my phone volume while streaming Spotify over Bluetooth. A few design flaws: 1) The power supply arcs when plugged in. That's not my outlet because Iโ€ฆ

Compact, inexpensive and powerful. Surprisingly big box.

When I got a new cabinet for my living room, I found that my trusty Music Hall a25.2 amp didn't fit on a shelf. Not wanting to drill holes in my new enclosure, I looked for something smaller that could still drive my Acoustic Energy Aegis EVO One speakers. My god, this device fits! Not only is it *much* smaller than I expected (about the size of a portable SSD), but it's also built very solidly and packs a real punch! Even halfway it's more than loud enough for my space. These are 8 ohm 100โ€ฆ

High quality, clear sound, unbelievable value for money.

This little stereo amplifier offers excellent value for money. I bought a model with Bluetooth and tone controls (bass and treble). It's really small, about the size of a paperback, but good things come in small packages. I hooked it up to small Bose bookshelf speakers and a pair of Cerwin Vega HT-6S (8 ohms, 125 watts). The sound quality in both sets of speakers was amazingly clear and well defined between the left and right channels with a direct left and right RCA AV input connection. Iโ€ฆ
