Short answer: the Soundcore Boom 2 Plus is the more portable boombox, while the W-King D20 makes the clearer case for karaoke use. The Soundcore is notably lighter than many peers of this size.
Its default tuning is warm, with upper-bass boost and rolled-off treble. That can be pleasant at casual volume but does not make it a neutral speaker.
The D20 includes two wireless microphones, an immediately useful distinction for parties. Its rising response, peaks around 700Hz and 1.2kHz, and rolled-off top octave mean vocals and instruments may not sound especially natural.
Buy the Soundcore Boom 2 Plus if lower carry weight is more valuable than bundled microphones.
Buy the W-King D20 if two included wireless microphones make it the more useful party system for you.
