The large piece fits my ear and holds in place well. But alas - when I set the mic up, I was disappointed to find that the tripod stand that comes with the mic couldnt even support the mic. , they are not comfortable! (Sidenote: a lot of these stickers seem to be based on fan art which is concerning to me because theres no artist credit anywhere?) COMPLETELY WORTH EVERY CENT! They connect easily to bluetooth so he can listen to podcasts and music wire free. Very easy install/set up. All for a tray that is too small to hold a full-size tool. Every time I attempted to use the microphone, the people on the other end of the call complained of an inaudible, muffled voice. Pop/crackle-free.
