How that actually works
The questions you wonder about mid-concert: earpieces, headsets, how singers do what they do. Plain answers, no homework.
- Why Do Singers Wear Earpieces? (What They're Hearing) In-ear monitors playing each singer a private mix, because a stage is too loud to hear yourself.
- Why Don't Singers Use Headset Mics? Plenty do, whenever they dance. Two free hands, a little sound traded.
- What Singer Do I Sound Like? (Find Out for Free, Honestly) Range and timbre decide it, and you can find out free with your phone.
On stage
How Do Singers Remember All Those Lyrics? (Some Use a Screen) Hundreds of repetitions, and yes, some pros use a teleprompter. Nobody thinks less of them. 
The K-pop Headset Mic (Costumes, Covers, Actually Singing) The look comes three ways: a $10 prop, a real system, or the touring gear idols rent. 
How Do Singers Actually Make Money? (The Part Nobody Sees) Live shows first, then teaching, then thin streaming money. The famous-artist lane is a separate lottery.
