Works great, very quiet 5 out of 5 stars

Reviewer: from Austin, TX

We have bought 1000s of these to give to our students. They use the speaker in a sound generation lab for our embedded systems class. Students make a 6-bit DAC with 0.75, 1.5, 3, 6, 12, 24k resistors, which generates about 0.85V peak to peak across this 150 ohm speaker. The sound is very quiet (perfect for 20 students working in the same room), One needs to put the speaker close to an ear to hear it. We love it because it is cheap enough to give every student their own speaker.
