Impressive Bluetooth Amplifier & Charger

After trying this product, I was blown away by the high quality sound it produces. The Bluetooth connectivity is quick and reliable, and the ability to charge my devices while listening to music is a game changer. The sleek design fits well with my other components but the only downside is that it could be more affordable. Overall, I highly recommend this product for anyone looking to upgrade their home audio system.

Pros
  • High quality sound, Bluetooth connectivity, charging feature
Cons
  • Price could be more affordable

all ok, still good price

yes i modeled it and put speakers in it, will be on sale soon, just a prototype, it's ok anyway, i think it would be better with other speakers with lower fs and ventilation, although it's loud, like 4 or 5x as loud as my phone isn't great but I think it's due to the speakers I used

Pros
  • ★Support USB sound card, free disk, plug and play (ordinary lithium battery power supply).
Cons
  • periodicity

Not bad, but there are some oddities.

I bought this for a Bluetooth speaker 3D printing project and it works absolutely as advertised. The included braids were a nice touch. Sound quality is good for such a small board, even through the redesigned PC speakers I used. However, there are some strange features. When you turn on the board, it guides you through the pairing process in extremely broken English at 5000% volume. I'm not kidding about the volume. No matter what I paired with it, I could never get anything else to play, even

Pros
  • ★Max. Working current 5V2A. It is powered by a regulated 5V2A or higher power supply and the sound quality is better.
Cons
  • Having problems
