XMSJSIY Mini Computer Speaker for Desktop PC 3.5mm TRS Input with Volume Control USB Powered Stereo Hidden Type Small Speakers for PC Laptop Phone Notebook -1.2M/3.9FT 1 Pair

I'm working on building a costume with a voice changer that's powered by a raspberry pi 4. While these speakers aren't particularly high-fidelity (you do get what you pay for), they certainly are small, plenty loud, and don't require a ton of power. Both the 3.5mm and USB ends must be plugged in to use the speaker. The USB plug is power-only and cannot carry audio data. For any other makers out there hoping to integrate this into a project: The speakers are held together with 4 very small screws. The chassis is a square shape but is recessed in each of the back corners, where the screws are placed. It was fairly easy to model a mount in TinkerCAD that made use of those screws and print it.

not bad for two small speakers, no bass of course, but good for dialogue (news), etc.

Worked very well in the beginning for quite a while. But now it puts out squealing sound when first turned on. Not sure if its speakers, Roku, ot TV. Noise doesn't last long just a few seconds.

Not a fan of the quality Poor sound . Not very loud. Scratchy sound

Pros: I was able to stick 'em on the back of a display that didn't have built-in speakers, but did have a headphone jack. Cons: Even though I have to power it, it sounds like there's no amp. They're very quiet. Cable management is tricky on a display arm: Dangling wires might show, even if you do a good job installing them. Sufficient for purpose. I just need basic audio. When I care about quality, I have better options.

Excellent for the price, and exactly what I wanted, I installed them in a raspberry pi arcade console project and they sound great, obviously not top of the line but crystal clear and at a respectable volume. The volume control on the wire is great if you need it like I did. 10/10 would buy again

Poor audio quality.

Freaking awesome speakers. These are tiny, you can hide them and yet they are loud and clear. I used these for a security camera system. Just amazing. Hooked right up to the camera. I ordered 4 different speakers for my needs and this one i kept.
