So far there are no complaints about it. I used it in an old external speaker accessory with a regulated 3.7V power supply and in another test speaker with an unregulated 5V power supply, the sound is about the same in both cases. I have only tested voltages from 3V and no higher than 6V without any problems. This may not be a huge issue for most as electronic components are now more durable than before, there can be DOA from static shock, x-rays or magical versions of 5G frequencies. The components arrived in a sealed electrostatic bag.
