Fosi Audio HT4S Bluetooth Amplifier for Outdoor Speakers, 4 Channel Power Amp for Home Theater, Outdoor Gathering, 4.1/5.0 Ch Stereo Home Audio Receiver, Supports AUX/Optical Input with Remote Control

Works wonderfully for my TV setup. I have it hooked up with a toslink cable and it was quick and easy to get running. I wanted something simple and compact. No large AV receiver. I'm just running 2 bookshelf speakers and a center unit all purchased second hand. This amp is good to power the three speakers. Best thing about something like this over a sound bar is that you can easily swap out speakers or add speakers to scale up the quality. Also the bluetooth quality is good. I was worried about that in consideration of what I had experienced in one of their older cheaper speaker amps but in this one the sound quality is solid.

TLDR: If you're looking for a beautifully built, excellent sounding bluetooth amp this is the one. It excels in audio clarity with little to no distortion at high realistic listening volumes, offers multiple audio input modes that you can select between with a convenient remote, and has the most output channels of any bluetooth amp for this price point. An absolute MUST BUY for any one in the market for a small nice amp.Right out of the gate, this new Fosi Audio bluetooth amp is absolutely amazing. The build quality and design are top notch given the price of this amp. Really hard to beat especially when compared to other similarly priced amps on Amazon.Rated at max power of 50watts per channel at 4ohms, this thing has enough power to realistically handle any speakers you throw at it given its use case. I tested these on my Wharfedale Evo 4.2 bookshelf speakers (these are no slouch!) and WOW what a difference in audio quality over my $1k Denon AVR for music. The DAC on this bluetooth amp is shockingly very clear and defined, definitely ideal for music. Added with the tone controls on the front of the amp, this amp is more versatile than ever. I've got 2 other models of Fosi Audio amps, and this is by-far superior to the other older models that I've got. It's got much better clarity and doesn't distort at higher volumes in comparison to the TB10D that I have.One of my favorite improvements over the previous model bluetooth amps from Fosi is that this new HT4S model has the ability to select your audio input mode. I can now swap between bluetooth on my phone for music and optical/aux in from the TV/Apple TV. On my older bluetooth amp from Fosi it was an on/off switch control and that was it. Both bluetooth and aux were active at the same time. So if I was watching something via the TV somebody else could bluetooth freely and play music over my TV audio which was very frustrating. With this new HT4S model that issue is now gone and the beautiful LED light bar on the front panel displays which audio mode you're currently in by changing colors.

Bluetooth connects quickly and works fine. This amp will be used in my garage, and I have concern that there is no fan in the unit. We'll see how it does during the summer months. For now, I just have a couple of Klipsch SB2 bookshelf speakers. The sound is decent, base and treble are fine, but the volume is pretty "meh". At high volume there is little distortion, but my ears aren't what they used to be. The setup will be fine but I'll likely update the amp at some point. My speakers have a lot more capability than what this amp can provide. All in all, for the money, not a bad unit.

Sounds really good, but only 35 watts per channel. I’m powering four outdoor rock speakers, at its highest volume it leaves a lot to be desired. My back yard isn’t very big and I have the speakers pointing at the pool from fifteen feet away. Other than that hookup was a breeze and the Bluetooth has great reach.

This amp is simplicity itself, it replaced an amp that was so complicated even Einstein would have had trouble trying to figure out the settings on it. This was so simple to hook up and the sound is perfect very easy to hook up to my tv with an optical cable and hooked up my sub woofer and it sounds great, if your looking for a good sounding amp that's easy to hook up this is the one for you.

Bass is too low, even turned all the way up. This is not 5.1 at all, just 2.0 shared across all connected speakers. Worst part of all, and why i chose to return, the controller WILL interfere with a TV nearby and in random ways. The volume up changes the input on my TV. Can you imagine that? Its unusable because of the smallest defect they cannot address other than to say point it away from my TV. Just not possible. The mute button literally turns off my TV.Shame, had promise

Sounds great… but I didn’t realize how annoying the no auto on feature would be. I read that but what it did not say is that it is actually auto off as well. So it has to be turned on manually constantly. And good luck finding another device that controls it reliably. Welcome to another remote

The build quality is quite satisfying with a sleek all metal enclosure and considerable heft. The adjustable 2-band EQ works, and can over power satellite speakers fairly easily, though for larger speakers it won’t push that much bass through them, but it advertises it as such, and the sub pre-out is a true pre-out with little-to-no noise. Total volume is surprisingly loud through 5 Klipsch Quintet |||’s. Bluetooth is stable and far reaching (near other side of house through walls far). Recommended, especially for the price point and compactness.
