Bluetooth 5.0 Power Amplifier 2 Channel Stereo Mini Hi-Fi Integrated Amp 2.0 Wireless Audio Receiver for Home Speakers Headphone 50W x 2 with USB (Douk Audio Tone, Black)

For my needs, this amp is pretty close to perfect. I am moving into a smaller area and needed a way to conserve space while keeping my turntable and speaker setup. This amp does the job fantastically and is an amazing value for the money.Pros:- Sound quality. The sound coming out of this thing is excellent, almost if not as good as my main amplifier. I had an initial issue with a background ground hum that came through on just headphones, but after many hours of use it seems that buzz has all but disappeared. There’s no whine or hiss added to whatever is played and it can get VERY loud.- Compact size. I’m not joking when I say the power supply it comes with is bigger than the amp, it comfortably fits in the palm of my hand but doesn’t feel flimsy or lightweight.- Inputs/outputs. This is the only mini amp I found like this on Amazon that has both passive speaker and a headphone output, along with a line level RCA input, Bluetooth, auxiliary, AND USB. Switching between those inputs is very fast and easy. A huge positive to me is that it turns off the Bluetooth transmitter entirely when not in BT mode, meaning you can keep your device connected to this and it won’t kill the device’s battery by always being connected, and it will automatically reconnect with your device once switched into BT. It also doesn’t let you go into the aux or USB inputs unless something is plugged in, just another nice quality of life feature.- Design. For the most part, I really like how this looks. Most wouldn’t assume such a small box with a knob and button would be an amplifier you could run a small stereo system through, and I think the mostly minimalist look is great. I do have reservations about it though, and I will go into those in the cons.Cons:- Lack of tone control. This is the biggest drawback for me personally, as my turntable setup doesn’t include a dynamic EQ of any kind before or after this, so if an album sounds thin or muddy, I can’t do anything to fix it. So far this hasn’t really been an issue, but it would be nice to have the option for at least bass and treble.- LED display. The VU meters that play on the front don’t actually mean anything, as far as I can tell. Other reviews have complained of them not being reactive enough, but I have found mine are far too sensitive and jump into the red for even quiet sounds. As well, I have tested and they don’t reflect stereo audio, playing something that has drastically different volume between left and right channels will give you the same reading on both meters.- Design drawbacks. The finish of the plastic on this isn’t the greatest, it’s rubberized but in a very chalky kind of way. As well, the mirrored front is a huge fingerprint magnet and seems like an odd choice. Lastly, it would have been nice to have the headphone port separated out a bit from the two front inputs, as it can be hard to get the headphones out if the aux port is occupied.Overall this is a fantastic little amp and definitely worth the money. Any complaints I have with it are really nitpicks, it ultimately did what I wanted and kept the sound of my main amp while being a fraction of the size.

This mini amp is feature packed; Bluetooth, front 3.5" aux input and headphone output, with auto switch from speaker to headphone output (when inserted or pulled out), bare wire or banana clips speaker receptacles, micro USB for use as a computer soundcard and more. The only drawback for me is the amplifier module. There is a good amount of harmonic distortion and there are no tone controls so it sounds a little thin. To be fair though, this is a class d amp but if you're on a tight budget and need an amp with an unusually small footprint that you could technically setup with an external eq, you will be happy with this.

Very impressed with this tiny little amp. I'm not an audiophile, and don't have high quality speakers, but it sounds good to me on Sony bookshelf speakers.The bluetooth feature has been pleasantly reliable. I wanted to be able to play audio from my computer, but was not thrilled about the prospect of running a visible audio cable between my computer desk and bookshelf. On a whim I tried the bluetooth feature. It connects to my 2019 MacBook Pro and STAYS connected, even after waking from sleep etc. We all know how this stuff goes and YMMV, but it's working very well for me.The blinkenlights do not disappoint, which is the main reason I chose it.The only negative I would say is that its that the unit is very light so any audio cables hanging off the back will tend to tip the unit up. This is probably something that could be solved with proper cable management.

Worked fine for one week then it would not connect via Bluetooth with my wife’s iPhone XS or mu iPhone 6 plus. I am returning for a refund and purchasing the same device of another brand.

Sound quality is amazing. The linearity of the frequency response is excellent. Blue tooth is finicky and stopped working for a period, but now works again. The first time I bought this, it wasn’t delivered because the product was destroyed in transit. Second time I bought it, the box arrived unsealed and it was lucky it didn’t come open in transit. This is 100% sloppiness/laziness on the part of the vendor. Easily fixed by actually just caring that the product arrives to the customer in one piece.

This Bluetooth amp is perfect for my vintage Stax earspeakers, which needs speaker level input. It totally revitalized and modernized my 40 year-old electrostatic headphones, which delivers unrivaled sound compared to any new headphones on the market today. The design and quality is of the Amp is great, and Bluetooth connection is a snap. Would highly recommend it.After using it for a few months, I noticed it drops Bluetooth immediately once the music stop, so if you are listening to music that has silent parts, or narratives, the next phase beginning will be cut off for a fraction of a second before the Bluetooth restarts again.Continuous music has no problem.
