Quick Answer
A USB cardioid mic is the right call for most parents buying for a teen: it rejects room noise and beats any built-in laptop mic. The FIFINE K669 sits near R900, the HyperX SoloCast around R1,200, and the HyperX QuadCast S near R2,200. Skip XLR until you need a true studio upgrade path.
USB Beats XLR Until It Doesn't
USB mics plug straight in with no interface and suit parents buying for a teen who want one cable and clean voice now. The FIFINE K669 (R900) and HyperX SoloCast (R1,200) are honest entry picks. XLR mics like the Shure MV7 (~R5,500) need a R1,500+ interface but open a real upgrade path. Start USB; move to XLR only when a second mic or a mixer enters the plan.
When a Boom Arm Earns Its Place
A boom arm clamps the mic off your desk, frees space and cuts keyboard thud picked up through the surface. It is worth the R600-R1,200 outlay for parents buying for a teen who type while talking or have a small desk. Match the thread: most mics use 5/8" while some need a 3/8" adapter, and the Rode PSA1+ or Elgato Wave Mic Arm both ship with the right hardware. Check your desk edge is under 60mm thick for the clamp to bite.
mic to cardioid, position it a fist-width from your mouth, and trim gain so your voice peaks near -12dB to keep res noise out of the stream.
