A few moments ago, I fixed a buddy of mine's powered studio monitors. I used an app on my phone that creates test tones that I used the headphone out into a 1/4" jack. It just had dirty contacts. So I text him letting him know his studio monitors were okay. I jump on AGF to post with you guys and what is being advertised? You guessed it - studio monitors. I don't think I've ever searched on the web for studio monitors and suddenly, I have a potpourri of ads for them. Scary.
