4 PCS Speaker 3 Watt 8 Ohm Mini Speaker 8ohm 3w Loundspeaker Micro for Arduino with JST-PH2.0 Interface for Small Electronic Projects Advertising Machines LCD TV Monitors

Don't expect as surround sound high def audio from these thing but they are better than other comparing size. The sound quality is good, volume doesn't crackle the higher you go, and is easy to hook up. They are good when using them for smaller halloween props or just those annoy circuits to drive a friend or family crazy.

Good sound for such a small speaker. Used with esp32 streaming radio project.

Second set of speakers I bought for a project. The first ones had no base and sounded bad. Theses ones are a little larger then I would like but they have great volume and sound awesome as well! Won't say they are high quality speakers, but they have great range and work well.

Solid speakers. They are pretty hefty and weigh in a hand nicely. Way heavier than cheaper ones. So, hopefully the magnets inside are better. They sound nice for their size. My only gripe is they are actually 8 Ohm speakers, not 4 Ohm as advertised (yes, I chose the 4-Ohm version, as it says on the label)

I bought these for some MP3 boards that also bought, They sound great even at high volume.

I needed to make a circuit that would create a "gong" sound for my cuckoo clock. These worked out fine. I don't have any data for sound (db) or range (Hz) because the gong sound didn't have much dynamic range.

The speaker fit right where I needed it sound was OK just using it hear CB radio using two speakers got 4 one speaker has something loose inside rattles when moving it.

These deliver much more volume and seem to have reasonable fidelity for use as a train sound speaker. Would buy again if more are needed.
