Review on 🎶 Bluetooth 5.0 Power Amplifier with 100W Class D Hi-Fi Stereo Audio, 2 Channel Mini Amp, Wireless Receiver for Home Theater, Treble and Bass Control - Douk Audio G3 (Black) by Kristina Scott

I was a little hesitant to buy this mini amp as it had no reviews on Revain and at such a low price it had many features I needed so I took a chance and bought one. All in all, this mini amp met, if not exceeded, my expectations! Especially for such a low price, this mini amp turned out to be a steal or bargain! Advantages: 1st prize! All these features and less than $40 is no problem for me! 2. Strong Bluetooth 5.0 signal strength and sound quality at least 60 feet away.3. Delivers enough power with high quality speakers (tested with 4 speakers simultaneously). 4. Does not heat up when used for at least 4 hours.5. Well-designed physical Bluetooth antenna (not internal).6. Good quality case, handles and connectors for the price.7. So far it has worked very well and appears to be a reliable mini amp.8. Large (strong enough) power supply with blue LED power indicator.9. Reliable production that responds to messages on Revain. Cons: 1. The device comes in a standard unprinted box.2. No detailed instructions or multi-page manual.3. The power adapter may not conform to some popular US standards. The device was packaged well, but there was nothing special about the packaging. I received it in a plain cardboard box (not a nicely printed box) along with a one-page folded manual. At first sight, the three dials seemed solid and rotated smoothly. The case was well made (probably aluminum) and felt solid from every angle. The rear connections and the Bluetooth (BT) antenna were of good quality both visually and haptically. The things I've been most concerned about with any mini amp are Bluetooth signal strength and distance quality, and whether or not the amp has enough power to drive four speakers. . What I liked about this mini amp was that it came with BT 5.0 and had a large 19V 3.5A power supply (you can find it for most laptops). So I tested this mini amp with my LG V35 phone (with BT 5.0) and was shocked and surprised to find that the sound quality and signal range from this amp was outstanding! The furthest I got from this amp with my BT 5.0 phone was about 65 feet separated by three rooms! (Living room, breakfast room, laundry room without doors). And it sounded great, if not flawless! I was amazed and satisfied that the BT signal would not be a problem. I really think BT 5.0 technology has a lot to do with signal strength and distance. If you are NOT using a BT 5.0 device, you will most likely not get quality and range with this mini amp. As for driving my four ceiling speakers simultaneously, it seemed to put out a LOT of power, so much so that when I turned the volume knob on this mini amp just past the HALF mark, my ceiling and windows seemed to vibrate! Also, the sound it produced was so powerful that the decibel level was probably close to that of a jet engine! Considering this power output, I didn't dare to turn the amplifier's volume to the maximum as this could damage the expensive speakers! I was impressed with the bass/treble mix settings, which sound crisp and clear even at max volume! Around the same time I realized that I have really high quality speakers! LAUGH OUT LOUD! It sounded like I was actually standing in front of a live performance and clearly hearing all the different instrumental sounds. All from such a small amp, I'm just blown away! Also, I run my speakers for 3-4 hours straight and expect this mini amp to get pretty hot. I've been using it for several days and the case never felt hot, always room temperature or warm at best! This device has a 3.5mm AUX audio input that can be connected from a TV or DVR with an audio cable. or any device directly with it instead of using its BT signal. If you have a device connected to the AUX port on this amplifier, note that to switch from BT to AUX audio input, you must first turn off the amplifier completely (by turning the volume knob all the way down until it clicks). Make it electronically "switch" from BT to AUX connection. Disabling BT on your phone will probably also help. At first I thought my amp was defective or I was using the wrong audio cable. But I soon realized that when you turn off the mini amp, you have to wait 5-10 seconds for the amp's BT to turn off electronically (internally) before turning the amp on (volume control). This "switching" from BT to AUX and back will be made easier once you've successfully done this a few times. I know there will be users who hate this and might return this mini amp in exchange for a much more expensive physical switch amp. I almost made that mistake and was willing to return this amp and spend about $70 for another one with fewer features but with that physical switch! So I give this Nobsound Bluetooth 5.0 Power Amplifier FIVE STARS for its sound quality, construction and BT. 5.0 with good range and good signal quality. Not to mention that he looks great! Also, the low price was lower than the Revain (after a few days of research!) with all these features (BT 5.0, physical BT antenna (no internal antenna in the case!), high quality smooth bass and treble controls). , well designed and durable aluminum body, large 19V 3.5A power supply with power indicator (blue light) to let you know the power supply is on, high quality chipset (TPA3116 chip and others) and some others functions. With all these "pros" I only had one "cons" and that was the power adapter which may not be US standard found in other adapters that you would typically find in the US. The power supply of this mini amp was probably sold for other non-US markets in my opinion and not necessarily for US households. Now the pin end of the adapter seems to be a standard size (2.5mm I think). If you're worried about that, you can sure find a better certified 19V 3.5A power supply for around $5 that fits in the back of this mini amp.
