Herdio 4-Channel Bluetooth 5.0 Amplifier 200W | Class-D Amp for Home & Ceiling Speakers

the package was never delivered. Herdio is not responding and the money has been paid in full.

Nice amp, good features. Sounds good.

I think this little amplifier is great! 4 speaker connectivity. Sound quality is great. Great range on the Bluetooth full volume control from my phone. Great features for expansion with the ability to daisy chain additional amplifiers. Small and easily tucked out of sight. I’m planning to add another and more speakers to my setup.

I have this mounted in a open pool pump shed up high on the wall powering some cheap external speakers to entertain the kids with bluetooth from their phones or a projector while swimming. Was easy and well worth the money. It is not climate controlled but is protected somewhat from the weather. The kids are happy and I use it when doing outside work for my own entertainment.

Perfect replacement for one tht got ruined in the rain... worked right away with very little setup and easy to connect. Overall it produces great sound and more volume than you might expect

Easy to set up just wish there was an outdoor version

This is a pretty nice and compact unit! Very easy to set up and use. I don't think anyone would have a problem setting it up. I haven't had any issues with mine. The fact that it can put off 200W for charging is impressive. The small size lets you stuck it almost anywhere and the bluetooth only adds to that ability. It's decently priced and the sound quality is excellent, but that really depends on what speakers you hook up to it. Overall, I'm happy with my order and I think you will be, too.

Sound quality is awesome. The price is a great advantage. This is my second unit purchased. Great durability using outdoors. Small size and fits anywhere.

OK, what a surprise out of the small mini amplifier. First off it’s incredibly useful for many different options. I used it to add an additional sound bar to my living rooms television system. So the features of having Bluetooth auxiliary in are awesome because it gives you different options for a source. I currently have it connected aux cable directly from my TV, which gives a great sound quality transfer. This product is super easy to use. The instructions are very clear. It is very small in compact so I was able to mount this where it is completely unseen. And given the price point and being very affordable as it is, this item produces a good amount of power. I was definitely surprised once I heard the results and it does a great job. I could see getting some more of these and using these in various applications from home theater system to a smaller shop stereo or even a travel size boombox.

Amazon is an awesome place to shop. With great products, great prices, and great with returns

these are really cool units for turning old speakers into Bluetooth speakers. They support TWS and everything else you've come to love from the Bluetooth protocol. Further, set up as a breeze. All you have to do is wire the speaker ends and outs to this thing and you are good to go.

Easy to set up, not complicated, and sound is great, Fits my sound needs

I wish the power adapter had a little mounting bracket as well. But I did purchase two of those they do connect well via Bluetooth together so I have a bigger area on one I purchased a plastic box drill the appropriate holes and mounted it inside underneath a roof eave and works great really have no complaints other than when you hook two of them it seems to want to hook to the first one even if the second one's a little bit far away I'm still trying to work that issue out eight speakers connected to two units separated by about 105 ft

Gran potencia, lo tengo instalado en la azotea con mis bocinas de exterior y la música se oye increíble...

This is a very good way to turn a bookshelf speaker into a Bluetooth speaker. I have a single bookshelf speaker that I really like but I wasn't using because the second one stopped working. I figured i could just screw this little amp on the back and use it as a single Bluetooth speaker.The setup worked pretty well, I was playing music as 90% volume for about 2 hours and I didn't see any issues, the amp was at a good temperature the entire time. I was only using one output so I'm not sure how the amp would hold up with four speakers while being pushed at high volume. The sound was pretty good, bass was plenty strong which i wasn't expecting it to be. I believe the bookshelf was rated at 100 watts.The downside to this amp is that the build is so so, it feels a bit flimsy. I also think they should have made the terminals easier to use instead of having to screw each wire in. The main downside is the power supply, it's a pretty large power brick which sort of takes away from the compact size of the amp. The power supply also sparks every time you connect it to an outlet, this is mostly likely because the amp is on by default. A different power supply preferably with an inline power switch would probably be a good upgrade to this amp.Overall I do like the way the amp performs but don't like the power supply they included with it. Bluetooth does work well. This would be a useful amp to make old speakers into Bluetooth speakers, testing speakers or even adding music to a small business with cealing mounted speakers.

This small amp gave me the option to mount it on the wall in a room where i otherwise had no room for it. The power supply is bigger than the amp but that is what gives it the power. Speaker mounting was a little tricky because the connections are so close.
