I listen to white noise to fall asleep. Should I get a white noise machine?

Hey guys, just like the title says, I find it easier to fall asleep when I listen to white noise / soothing sounds. Currently I just use free stuff off my phone, but was curious if anyone here uses a white noise machine? I know they can range in prices but maybe it's a better option that constantly using free stuff I find on the internet. Plus, it's not great to sleep with my phone next to my head, right??
