Short answer: the LG Xboom Stage 301. It ranks #36 of 112 boombox speakers by sound quality, rated 3.7/5, at $229.99; the JBL Partybox On the Go ranks #66, rated 3.0/5, and costs $249.95, so there is little reason to consider the other one.
Why pick the JBL Partybox On the Go: A battery party speaker with an included wireless microphone and a detachable shoulder strap. Watch for: Bass is limited by its 49Hz specification.
The LG Xboom Stage 301 is the better-sounding, deeper-bass pick. A wedge shaped karaoke speaker with a swappable battery and multiple standing positions. Its bass reaches about 43Hz before falling 10dB, against 49Hz for the JBL Partybox On the Go. It is rated for 12 hours of battery against 6 for the JBL Partybox On the Go. It supports AAC Bluetooth, which the JBL Partybox On the Go lacks. The catch: overpriced for what it is.
Buy the LG Xboom Stage 301. It is rated higher for sound quality than the JBL Partybox On the Go and costs less, which makes it the one to get unless you need something the other one does better.
