Short answer: the Harman Kardon Onyx Studio 6, unless you want the LG’s karaoke features. The LG Xboom Stage 301 works as a karaoke hub with a removable, replaceable battery, but it is overpriced for what it is and its frequency response is not the greatest. The Onyx Studio 6 is warm with boosted bass and not as loud as others, at $130 versus $229.99.
On the Harman Kardon Onyx Studio 6 side: Warm sound with boosted bass. Oluv liked it slightly better than the newer Onyx 7. Watch for: 8 hour battery at medium volume. Not at loud as others.
Buy the LG Xboom Stage 301 if you want one new; the Harman Kardon Onyx Studio 6 is discontinued, so only look for it used.
Water resistance is not close: the Harman Kardon Onyx Studio 6 is rated at IPX7 (brief submersion), well ahead of the LG Xboom Stage 301 at IPX4 (splashing).

Harman Kardon Onyx Studio 6: $130 Discontinued Amazon eBay
Newer model: the Harman Kardon Onyx Studio 9, ranked lower, rated 4.1/5.
Pros: Harman Kardon Onyx Studio 6 uses a 120mm woofer, 25mm tweeter and passive radiator. Its 2.94 kg, claimed 8 hours (Manufacturer specified) battery life, IPX7 protection, aux input and up to 96dB make it a practical option for its intended room or portable use. Measured bass extension of 37Hz (-10dB).
Cons: Bass is limited by its 37Hz specification. There is no companion app. No EQ adjustment. Warm tuning with boosted bass, and not as loud as others. Discontinued.
