é gia il secondo che compro, sono semplici esteticamente quando montate, hanno una forma facile anche da modellare in 3D, e suonano discretamente per il tipo di prodotto che sono, si collegano i pin e sono pronte all'uso, sbattute ovunque, collegate e scollegate brutalmente e nonostante ciò sono ancora funzionanti

The audio is crisp and clear, with well-balanced tones that handle both highs and lows effectively.One of the standout features is its passive enclosed design, which helps to enhance sound projection and minimize distortion. This makes it ideal for a variety of DIY projects, whether you're building a custom audio system, upgrading a small device, or working on educational electronics kits.I used this speaker to build my own smart speaker for Home Assistant, and it performed exceptionally well. The integration was seamless, and the sound quality added a professional touch to my setup.Installation was straightforward, and the build quality is solid, ensuring durability and reliability. The speaker's compact size means it can fit into tight spaces without sacrificing sound quality, making it versatile for different applications.Overall, the CQRobot Miniature Loudspeaker offers excellent performance and value for its price.

They sent me a defective product and the return is a nightmare! they sent me and address in China to return and it's not even a free return. Post office will not accept so I need to take it to UPS or Fedex which I wasn't able to ship because shipping fee is more expensive than the item. And they also want a proof that the item is defective, they needed a video that proves that it doesn't work (then I have to pay the technician again to do this ,which again I refuse to do because it is quite expensive) ..So much hassle!! So please DO NOT BUY FROM THIS SELLER!! i HAVE NEVER COMPLAINED ON ANYTHING i BOUGHT FROM AMAZON, BUT THIS ONE IS A NIGHTMARE!!!BUYERS BEWARE!!

Sonido más fuerte y limpio de lo que esperaba. Los compré para conectarlos a un módulo lcd para convertir una pantalla de computadora portátil rota en un televisor independiente y funciona perfectamente.

Article de qualité plutôt moyenne, bien fait mais le rendement sonore est très moyen. Un des 2 haut-parleurs a des des dommages à la membrane.
