Short answer: the Stage 320. The two are close in price ($499.95 versus $399.99) and the Hyperboom is a genuinely well-built speaker, but reviewer feedback describes its sound as a bit dull and muddy for the money, and it’s not as loud as its size suggests.
The Hyperboom’s strengths are battery life and portability rather than party features. Its square cabinet with a sliding handle claims up to 24 hours at 50% volume, includes dual Bluetooth pairing and adaptive bass compensation for reflective rooms, and is IPX4 rated. It has no lights, no karaoke mode, no wheels and no mic or guitar inputs, so it’s built for portable listening, not hosting.
The Stage 320 is built specifically for parties. It keeps more bass at high volume than JBL’s own prior-generation model, and its karaoke echo mode, dual mic/guitar inputs, wheels, removable battery and Auracast support all address things the Hyperboom simply doesn’t do. Its own compromise is a slightly sibilant treble at full blast.
Buy the Hyperboom for a more portable, longer-battery speaker for everyday listening rather than hosting.
Buy the Stage 320 if you want lights, karaoke and mic inputs for an actual party.
If water resistance matters to you, the JBL Partybox Stage 320 at IPX4 (splashing) holds up far better than the Ultimate Ears Hyperboom at no water resistance.
