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.

These are good speakers for its price, the bass is pretty good at close range, but that can sound unclear the farther you move.

Sound good for what they are. I glued them to the back of a quite expensive professional monitor that oddly didn't have speakers built in, they sound good enough all around for watching youtube videos and web calls and light gaming.

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

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

Works OK for my use.

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.

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.

I bought these speakers for a small Linux machine that I was playing with as I wanted to have sound output and didn't want to have anything large. The speakers are quite heavy for the size and this reflects the powerul magnet. The sound is full range as there is only the single driver in each case, however the sound they produce is very good for something so small. The double sided tape makes mounting these a breeze and the inline volume control is a nice feature. They are of course powered by USB, or you could use a wallwart to power them and save the port. The specs say that these are rated for 6 watts however I suspect that this is based on 3 watts per speaker. I don't have any way to measure the actual power output, however they are plenty loud enough as far as I am concerned. Great speakers, great price, great value!!

They're tiny and useful to a degree. They're more of a novelty item from my perspective.

These are completely useless, not amplified DO NOT WASTE YOUR MONEY

For a pair of tiny speakers they put out a lot of sound.

Worth the price. Works in a pinch, but pretty tinny sound.
