If it's using a modern version of android USB audio is baked into the OS by default. Plus if it can support and external hdd already than it is only a patch away from being able to do it. I'd say chances are pretty good then.
Will look into those. There is definitely a bit more life and clarity to the left now without the filter so it was certainly the culprit. Completely waxed over underneath. I would go filterless but I don't trust I can keep them earwax free, and would like to avoid too much tamperingg so I will definitely be looking into the RE0 filters
