Short answer: the Onyx Studio 7 for sound, the LG Xboom Stage 301 for karaoke. The Onyx Studio 7 delivers warm, bass-boosted sound with an 8 hour battery at medium volume, though our notes call it a little sterile and say it has a teeny bit less bass than the Onyx 6. The Xboom Stage 301 wedge design works as a karaoke hub with a removable, replaceable battery, but it is overpriced for what it is and has not the greatest frequency response.
Buy the Harman Kardon Onyx Studio 7. It is rated higher for sound quality, and the $18.91 saving on the LG Xboom Stage 301 is not enough to make up the difference.
There is a real gap in water resistance: the LG Xboom Stage 301 at IPX4 (splashing) against the Harman Kardon Onyx Studio 7, which has no water resistance.

The Two Speakers In Full
Harman Kardon Onyx Studio 7: $248.90 Amazon eBay
Newer model: the Harman Kardon Onyx Studio 9, ranked lower, rated 4.1/5.
Pros: The addition of dual tweeters gives the Studio 7 a wider, more spacious presentation than older Onyx models. It delivers strong, deep bass, useful large-room volume and can pair with a second Studio 7 for stereo. Measured bass extension of 37Hz (-10dB).
Cons: Consumer Reports finds the bass prominent and boomy, mids hazy, treble slightly smeared and the soundstage congested. Battery life remains only about eight hours, it has no water rating or advanced codecs, and it is not an especially loud outdoor speaker.
