Mine has an equaliser, different modes, can do firmware updates, incl the manual etc. Manual is handy as I can't recall the presses to do various things. Mine also has a feature where it uses rhe mics to include ambient sound to the audio. Rather handy so you don't get run over etc...Thanks for reminding me....need to check that.
Strange, nowadays everyfucking thing has an app.
So it wasn't the best buy for you? Because no app??
