There’s not much point to an in-person audition if you’re basing your decision on the audio from a smart phone. For that matter, why bother with high end audio at all if you’ll just be listening on your phone to things like YouTube?
1) Use a video cam if OP likes.
2) Use a headphone to hear cell phone (CP) recording.
2) Many hi-end audio videos in YT recorded by CP sound great. Use an external mic if avail.
3) Almost every sounds have a signature. ex.)One can id when he hears voice of their family even if the recording is bad. People know the sound of their audio system to compare sounds of others.
4) Many people (not everyone) can still understand which sound is better through inferior CP speakers. ex. 1) the world greatest audio system video vs. regular sound system video." ex. 2) "the world greatest audio system video vs. the original music."
What has OP got to lose anyway? The recordings could be a good reference.
