Okay, it's far from the BEST speaker, but it's fine if you're looking for a standalone USB-powered audio solution for your Raspberry Pi project. They are not very loud but are 100% USB powered and use the onboard sound card. They don't (and don't need to) be plugged into the PC's 3.5mm audio jack as the sound is transmitted entirely via USB. The Pi 3 when powered by a 2.5-3.0A power supply is more than capable of powering a speaker so would be a good speaker for any Pi project. I use mine for holiday decorations - I use one to add sound to my Halloween skeleton and the Pi to play sound through the speakers. I just bought 2 more for other Pi projects I'm working on. Anyhow, they work well in prototyping and development to ensure the sound works for the Pi app. Please note that the speaker's fidelity is not the best, especially at high volume, resulting in distortion from the vibration of the plastic case. So, for my use case, I love these little speakers. I would not recommend using them as speakers for normal music playback. In that case, you're much better off getting a Bluetooth speaker or some other well-known externally powered brand, such as the Bluetooth speaker. B. from Logitec, Bose, Anker or others.
