#8 JBL Partybox 520: $879.95 Amazon B&H Photo Video eBay
Pros: JBL’s biggest battery-powered PartyBox after the 720 combines very high output, deep chesty bass, wheels and a telescoping handle with a capable app EQ, lights, USB-C audio and mic/instrument inputs. RTINGS finds it loud enough for backyards and unusually well-equipped for a battery party speaker.
Cons: It is very large and heavy, Bluetooth latency is high for video, and its front-facing design loses much of the mids and treble to people off to the sides. The bass-heavy default can also make dialogue less clear without EQ.

How it compares: Just above it: JBL Partybox Ultimate 2. Just below it: Teufel Rockster - 15 more hours of battery life.
