A sort of sonic Instagram: several filters are adjusted at the external frequencies, adapting them to the dynamics and context of the environment, allowing to choose what we really want to listen to. There are two very simple functions: turn out and turn in. The former allows blocking the sound around you, while the latter sets the way the sound comes from outside.
If there was anything tech related that I would beg for a review copy of, it's this. I could test it out on how well it blocks out the parrot.
