Review: Perfect . . Exactly what they claim to be - Excellent price for 4 of these small hobby speakers. Perfect for use with Arduino, PIC, Pi, etc. They sound good and have plenty of volume. I found mine easy to mount using threaded standoffs and machine screws. As for music, they probably won't make you get the Led out. They don't produce much in the bass range (below 500 Hz) but normal voice range is fine. They would be a good choice for a radio receiver. Mine came with the JST connectors The video below shows one driven with a Raspberry Pi Pico and small headphone amplifier
Review: Perfect for xbox 360 modding - Yeah so I got these for the xbox 360 to add better SFX to it and it so good, fits in like a charm! You must get these if you mod or do your own projects
