Perfecto lo que buscaba muy facil de usar lo uso en mi patio 2 cornetas suena muy bien lo puedes usar con jack o bluetooth

I can't believe what this little amp can do. The Bluetooth works great. I'm waiting on the second one to test the tws function. I definitely will be buying more of these guys. Using this amp in a diy portable Bluetooth speaker setup. 12 volt rechargeable battery is powering up the amp!

For the price, this amp is extremely flexible in what you can do with it. It has bluetooth, 3.5mm aux-in, left and right channel and the ability to run two of them in TWS (true wireless stereo). The use case for this (TWS) would probably be to add one amp to each passive speaker so that you don't need a cable running in between the two speakers (but you will still need to plug each amp into power). It does not say if there's a single channel "bridged" mode so I'm not sure if you're getting 30x1 if they are running TWS with two speakers.The only drawback is that the volume is only able to be controlled through your device you are hooking to it. So there is likely no good way to run a record player via the 3.5mm input to this as that'll be a fixed volume line-out. Your old CD Walkman though, piece of cake as you use the headphone out and control the volume from the CD player. Same goes if you use bluetooth via your phone. All volume control will be on your phone.They also don't go into detail about the internal DAC. Although most these days are pretty good, always assume an inexpensive one if the product does not detail anything about it.

No loud beeping as the one I replaced was very annoying.Would be nicer with a volume.

Disappointed. 5 months later and it stopped working.

I build loudspeakers as a hobby. I've built about six pairs of passive speakers, a tube amp, a powered subwoofer, and 2 tabletop powered Bluetooth speakers. I ordered this little device with very low expectations. It absolutely amazed me when I connected some passive speakers and connected Bluetooth from my phone. Shockingly loud for what they claim is a 30 W amp. Bass was good and deep. It didn't shake the windows at max volume, but it wasn't distorted either. Pretty useful for the price. And it's 30% off at this time, which is a bargain.It's a pretty bare-bones product. The power adapter is 12 V, 3 W, and only has a 3 ft cord, so you may need an extension cord depending on location. Based on the adapter, I think the 30 W rating is 15 W/ch.A few other things to mention. There is no power switch on this device - once it's plugged in, it starts searching. I plan to add it to some passive speakers and add a switch. Also, there is an aux connector that can be used instead of the Bluetooth wireless feature. I have no idea how to switch between the two, and the manual didn't have any useful information about this. Finally, it claims a "TWS" feature that allows for pairing two of these devices together. The manual has no mention of this, but the product listing does. It might allow for one of these to be mounted in two separate speakers and treated as left and right with 2x the power? I have no idea, but I may have to look into this. A 30 W/ch speaker pair would be a very useful solution.EDIT: I ordered a second one of these, and it was dead-simple to use the TWS feature. Just flip the dip switches on both devices, connect each to one speaker channel (L or R), plug them in, and pair with a phone. The phone connected to both devices and provided stereo sound to them. This is a big deal - I can embed one of these in each of a pair of passive speakers, add a switch to each, and plug them in across a room to create an active speaker pair. They will work as a stereo pair without a speaker wire connecting one to the other. Really great feature - I'm planning on upgrading a passive speaker pair to active where each would be plugged into a wall. I believe the power was boosted since only one channel was connected, but it's difficult to tell, so I can't guarantee that. But for the price, these are a steal. The sound was great driving some DIY 3-way speakers. Highly recommended.

This works well and is easy to pair to another of the same amps. The power input is 5.5x2.5mm, so you likely will need an adaptor if you’re using a battery.I wish the actual board had stand-off holes so I could mount it without the plastic case. I also wish the power input came out parallel and not straight up. Otherwise would be a five star.
