Just curious about this. When looking at lower end android phones, sometimes people will say audio quality is okay, or that the mic isn't the best that it distorts sometimes etc. I'm looking at a phone just to use for voice calls, so hate to get a high end phone just for good quality. If I was going to use a headset with it, either bluetooth or headphone style ones, does that change anything with the audio quality? Guess I'm just wondering if the majority of the quality comes from the speaker and the mic, or if it's more the internals of the phone. So a phone that has a review saying the mic is so-so, would that be potentially fine when using a headset or would I expect the same quality? Was looking at getting the HTC Desire 601 because I just need a cheap phone that's just for making calls, so I hate to spend a ton on a higher end phone like Moto X or Nexus 5 etc when I don't need any of the smart phone functions. A review I saw said the mic is not the best on the Desire, but it's so hard to tell on what they are comparing it to.
