Enclosed Speakers 3 Watt RMS 8 Ohm for Arduino 70mm (L)×31mm (W) | Front-Firing, JST PH2.0 2-Pin Lead Wires, Rectangular, 4 Corner Mounting Holes, for Electronic DIY Projects, 1 Pair

They work really great and sound good

I have them on a KOOBOOK mp3 playback module and an esp32 that’s monitoring a solar panel system and the volume is plenty loud enough to hear across the room even with the volume turned to the middle of the range. These mount from the front, that is the mounting ears are flush with the front of the enclosure. For my purposes it would be better to have them flush with the rear to allow surface mounting but I can use standoffs.

Size and look is great. Appear to be made decent and good value. Just too quiet for sound effects in a cosplay suit.

I bought this to use as a Google Assistant speaker on my Raspberry Pi 4 with a Respeaker 2 mic HAT. I had wanted to plug in a 3.5 mm based speaker, but I didn't want it to be powered. I initially tried using some headphones with a really long cord and with the volume turned up all the way, and this kind of worked, but the raspberry pi started overheating. I tried this JST-based speaker, and the speaker is exactly what I needed. It's clear and loud enough that it can talk over me if I'm talking to someone else. The temperature readings have remained normal. Since it came with two, I have an extra speaker if I decide to get a mic array for my raspberry pi 3! Many thanks to shivasiddharth's GassistPi github project for allowing me to use my raspberry pi as a google assistant device. Only downside is that it doesn't play spotify or other DRM music, but it lets me control my smart home via voice, and that's way more than enough.

I was concerned these would be too "quiet" because of their size but they worked perfectly for my project. Ample sound volume and quality.

Also good

Slightly better than expected. Used it to make a Galaxy Note 2 louder than 80% of phones available. So it's probably as loud or a little louder than most phone speakers, but it adds a little depth just from is physical qualities. Got both this speaker and my phone speaker playing. It's a super niche thing, but I wanted it done. For the other 3 people in the world that want to do this make a comment and I'll make a video on how to

don't expect any loud audio out of those, but for a quiet environment they are OK.

These are teeny tiny, but the quality of sound is what you expect for the spec and price,

Für den Preis ok, klingen ganz gut.

Good quality

Decent volume without distortion. Easy to cut and solder the wires. Exactly what I was looking for!

Worked as expected. Used the 2 speakers on different projects with Google Assistant
