Color: AK-45(2.0CH 40W+40W RMS)
I'm impressed. So far, this little amp is way above what I expected in sound quality. I'm using it with my phone that I'm using as a Pandora server. Since the amp has no real equalizer and I needed some adjustments there to get rid of the slightly boomy bass, I used the EQ in my phone (it's a Samsung S22) and the change was amazing! Also, since the amp has no control of the signal coming into it's line-in ports, when I switch from line to FM, the volume increase is frightening! I found that permanently raising the volume on the phone makes this a little less scary but still needs to be adjusted at the amp. Not a big deal for me, since I rarely use the FM, but it would be an issue if I did. The fix for me is to make sure I make the switch at the amp where I can turn the volume down before I do the switch. Interestingly, turning the volume to max on the phone actually improved the sound quality. I'm running a pair of vintage Nakamichi Sound Space 7 speakers. No discernible distortion at anywhere near normal listening levels. I use this setup mostly for background music at a moderate levels. Sometimes I crank it up a bit and it's still fine. The stereo separation is impressive. The amp has no balance control. Fortunately the Nakamichi speakers are very directional, so I can fine tune the balance by slightly adjusting the speaker placement angles. The remote is interesing. For example, the volume adjustment is slow. I have to hold down the button for a few seconds before you hear any change. Using several quick presses works better. The On/Off button turns off the amp but leaves most of the settings, and the blue LED around the volume control on. You can use the on/off switch on the amp to power it down completely, but then you'll use some settings. The LED consumes such a negligible amount of power I just use the remote. I have not had the patience to connect the Bluetooth, I will eventually. I think the reason for it not connecting is that there are so many Bluetooth gadgets in this house that could be interfering with a connection. The phone "sees" the amp but won't connect. So many reviews say how easily it connects, so it's no doubt an issue I can fix. One disadvantage to good Bluetooth range! Bottom line: This little amp works well for my use. Very well. The most important thing to me was sound quality; I didn't expect it to compare with a $400 amp in all it's other features. Another plus for me is that it's diminutive size lets it all but disappear on the shelf. It's 7" wide and you need to figure 8" deep to allow for the cords coming out the back. I'm giving it five stars for my use. Your mileage may vary! OK, it's now been a few weeks and I have an update. That remote. as noted above, it was a bit hinky from the start in that the volume didn't work right. So it continued to require longer waits and more presses to get the volume to change up or down. Finally it just stopped working. The remote still turns the amp on and off and the few other function I use it for work, but the volume, which for my use is the most important thing to work properly, has ceased to work, so now I just assume that there's no remote with this product. Bummer, but the amp still works as described above: very well. Maybe the seller/manufacturer reads these reviews? That would be good.

I liked it, it's small, simple, and easy to connect. Fair and good quality sound. Easy to manage, and it's not heavy. High and long signal strength. You can play it for hours.

Purchased for Home surrounding system: solid case of metal (not plastic). Tested all functions except mic and worked as expected. Output power is enough for home use. Blue tooth connection is very reliable with 30-40 feet . Sound quality is acceptable ( depending on sound source). FM radio signals are little weak. USB/MP3 playback is good. Remote control well designed. Two shortcomings: 1 a loud sound comes out when switching functions and no way to make it quiet; 2 poor user manual and operation instructions.

This little Bluetooth 5.0 amplifier is a perfect example of keeping things simple and actually making life easier. I hooked it up to a pair of speakers in just a few minutes, and it was up and running without any complicated setup or confusion. The Bluetooth connection is quick and stable, so pairing your phone or tablet is effortless. Once connected, it delivers clear, solid sound that’s more than enough for a small room, garage, or even a casual outdoor setup. It’s not trying to be over-the-top, it just does exactly what you need it to do and does it well. The remote is a great touch too, letting you adjust volume, switch inputs, or control playback without getting up. It adds convenience without overcomplicating anything. Overall, this amp is all about simplicity and practicality. Small size, easy setup, reliable performance, and no unnecessary extras getting in the way. If you want a straightforward way to power your speakers and stream music without headaches, this is a great choice.

There is a loud hiss that comes from the amp, doesn’t get very loud at all even on max volume, and the Bluetooth cuts in and out all the time. 1/10…

My requirements: Small, Light weight, sounds decent, cheap. Be prepared with a powerful magnifying glass if you want to read the manual, which is written in transliterated Chinese. Power cord is 3' long. There's no cord supplied for the 12V power input, so this was not tested. Knobs are black with a black notch to indicate the position - very difficult to read. The unit forgets the FM station when turned off. The unit shipped with the volume knob turned to max. Be careful with that initial test!!! Line input is RCA, and outputs are the old wire clamp method. Remote control uses a 3V CR-2025 watch battery (supplied). The volume buttons on the remote were confusing - they allow you to change the volume up or down UP TO THE SETTING OF THE VOLUME KNOB on the device. Bluetooth worked, but seemed to require a higher volume setting than radio or AUX input. The manual is silent on what type of microphone can be connected. I used an ancient Realistic Highball-7 (impedance 600 ohm) mic that was at the bottom of a box of unused gear. It worked OK. Couldn't get music to play from a USB memory stick at all. It just didn't recognize it. Using an old SD card did work. Is it possible that the player doesn't recognize newer types of USB sticks? USB sticks are typically compatible with older devices that try to read them. Luckily, playing from USB sticks was not something I need to do with this device.
