## Questions & Answers

**Q: where do I plug it into my raspberry pi? I think it's the pins but which ones?**
A: If you have a 3b+ then you need to feed the loudspeaker from an amplifier module attached to the line out socket. If you are using a pi zero then it is more complicated. Easiest is to use a hdmi to audio dongle, then the amplifier, then the loudspeaker.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works as expected
*by L***N on 15 July 2024*

Good value, works as I expected it too and good clear audio output.

### ⭐⭐⭐⭐⭐ Better than the 4" type, very small, good sound
*by T***N on 24 April 2021*

I got these for my latest arcade project, as space is minimal, I needed a small speaker, these are tiny, but give better sound than the usual cheap 4" type everyone uses, they also work with the "l-pad" type attenuator, I got the Monacor brand.

### ⭐⭐⭐⭐⭐ Great Little Speakers
*by P***R on 4 July 2020*

Purchased these for a project for Christmas , to play music on a diorama, with a Christmas theme, these are small speakers but work great.
