Short answer: both are discontinued, so this only matters if you are buying used. Used, the Harman Kardon Onyx Studio 5 is the better pick: it ranks #24 of 98 boombox speakers by sound quality (rated 3.9/5), against #75 (rated 2.7/5) for the W-King H10. If you want one new, the Harman Kardon Onyx Studio 9 replaces the Harman Kardon Onyx Studio 5 and is rated 4.1/5 at $189.99.
The Harman Kardon Onyx Studio 5 is the better-sounding option. The iconic circular cabinet and integrated handle make it an attractive room-to-room speaker. It links with other speakers (Wireless Dual Sound), which the W-King H10 cannot. The tradeoff: The large bass boost can mask lower-mid detail and make dense mixes muddy.
The W-King H10 is the longer-running choice. Comes with wireless microphone. It is rated for 24 hours of battery against 8 for the Harman Kardon Onyx Studio 5. It has an adjustable EQ, which the Harman Kardon Onyx Studio 5 lacks. The tradeoff: Not very deep bass.
Buy the Harman Kardon Onyx Studio 5 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the Harman Kardon Onyx Studio 9, which replaces the Harman Kardon Onyx Studio 5.
