I know they are tiny and I'm tired of the smallest SM components so far but what's in your phone to include iphones. The chip is a US made product and is much more expensive in many other boards. According to the research, the traces on the circuit board can conduct electricity. My tests show great results, as do some YouTubers. Having rated the Pam 8403/5 boards as great, they sound even better. So sometimes I buy a few for my stash. The only thing I don't like is the small size, there's no real way to install a heatsink for 4 ohm operation. But my favorite speakers are 8 ohms. Use good quality speakers, cheap ones just don't sound good. They are thin and fragile, so screw mounting is disabled. Use 2-sided tape or hot glue to install them. After all, none of the few I tested failed. None of the pack were dead. Only one had a crooked capacitor that looked like it had shorted out, but played like the rest. These have never let me down. And a test: I hooked it up to some old 15" Magnavox Alnico speakers and they got really loud. They rattled the windows and I thought they would break. I like the ability to adjust the gain, 20, 36 dBl. For PC or Bluetooth module. You won't get this option too often. So don't worry about the power rating, it's rated for 4 ohms. With no heatsink I stick with 8 ohms and they work fine.
