Both units worked fine and are as represented.
Using with Arduino (or clone) Uno / Nano and a 3 watt amplifier it sounds great. Not tinny or tiny sound. Deep notes sound good.

No problem recommending, assuming the size fits your project.

Reviewed in the United States on July 29, 2022
Size: 8O5W-Dupont2.54Verified Purchase
These fit the bill for a grade-school presentation board with wires spliced into a stereo 3.5mm plug running from an MP3 player... A 16-ohm option would have been nice as it wasn't as loud as I'd liked with the low amplification, but it worked well enough without having to run it through any additional equipment. And I'm honestly impressed with the fidelity of these, for what they are.
