These are not really the same size class, and that is the honest framing here. The Soundcore Boom 2 Plus ranks #39 of 113 boombox speakers by sound quality at $169.99; the W-King T9 Pro ranks #38 of 53 party speakers by sound quality at $171.49.
The Soundcore Boom 2 Plus is the longer-running, lighter option. A fairly light stereo boombox, easy to carry to the beach or park. It is rated for 20 hours of battery against 12 for the W-King T9 Pro. At 8.4 lbs (3.8 kg) it weighs much less than the W-King T9 Pro at 20 lbs (9.05 kg). It is rated IPX7, while the W-King T9 Pro has no water resistance. Watch for: Warm tuning meaning a rolled off treble and some upper bass boost.
The case for the W-King T9 Pro: A rolling party speaker with dual woofers, a removable battery for long events, stereo pairing, and music synced lights. Watch for: Reviewer comparisons describe the tuning as warm and gritty rather than clean or detailed.
Buy the Soundcore Boom 2 Plus at $169.99 if you want a boombox speaker. Buy the W-King T9 Pro at $171.49 if you want a party speaker instead.
