4pcs Mini Speaker - 3W 4Ohm, Loudspeaker with Dupont Interface for Arduino & Small Projects

These speakers supply sound to my outdoor railroad. They are mounted in rail cars and buildings. they work well in this capacity.

The media could not be loaded. When I had this speaker plugged up, I went back to the listing because my initial impression was it was a 2W or lower speaker. I have a 3W speaker twice its size. Because of its size, it is all treble.There is a review on here saying the product is barely audible, but that really isn't the case. If the speaker is properly driven, it could get loud. It could get loud enough to hurt your ears. This all has to do with the programming as well as the components used to drive the speaker.I added a video to demonstrate the sound quality of the product. It is from NCS or NO COPYWRITE SOUNDS.I did break it open so you could get a better idea of what is inside the case. It is not necessarily the best design to project audio, but it could have its applications.Overall it is a good product. If you need something with a small profile, this may be what you need. I recommend giving it a try.

The sound quality is excellent for the price

I ordered this 4-pack of 3 watt speakers from DWEII to use with Arduino projects. While they all work just fine, the volume output is lower than I expected, and I didn't have high expectations to begin with.We use an Arduino mp3 encoder to make more interesting audio clips.I don't think I would buy them again.

I am very happy with this item.I ordered these to use in Arduino projects where I wanted to play a more complicated warning sound than sounding a buzzer. They are great in that role.I wouldn't have high expectations regarding sound quality. They are perfect for what they are intended for but are more like a laptop speaker than something you would choose for high quality music playback. They pair well with the LM386 amp chip and can get quite loud but they're fairly tinny and have lots of treble. I can attest they reproduce a tiny air raid alert sound pretty good!Overall, I'd definitely recommend these for their intended purpose. If you are looking for high quality audio for music you might not be happy.

I ordered these because they were inexpensive and will enable me to get started with a long term project. I can afford to spend time trying them out and getting hardware and software to work with them, but I am not minded to spend money on ‘ideal’ speakers, only to find I don’t make a good job of the hardware and software. On that basis, the sheer affordability is by far the most important issue for me at present.

These are nice little speakers for small electronics projects that need sound, but not a lot of it. Sometimes I make small audio effects or simple video games using ESP32 boards (or other microcontrolelrs), and these little speakers are perfect to bring out some basic sound. I like that these come with either JST or DuPont connectors, which makes it very easy for your particular application. They are not hi fi speakers with room shaking bass, but for what they are, they are great. 5 stars.

I haven't used any of them yet for a specific project, but have a couple projects planned that will require audio feedback and these will be perfect. I tested one just to see if they work well and they're great for projects that need an audible feedback or button press confirmation by sound.
