These are not really the same size class, and that is the honest framing here. The JBL Partybox Stage 320 ranks #3 of 39 party speakers by sound quality at $499.95; the Soundboks 2 ranks #8 of 14 battery-powered PA speakers by sound quality at $449.
Short answer: the JBL Partybox Stage 320 is the better-reviewed of the two, 4.6 against 3.2. Worth noting on the JBL Partybox Stage 320: Handle and wheels are convenient. The Soundboks 2 leads with built for maximum outdoor output: its two 10-inch woofers and silk-dome tweeter reach a claimed 124dB, while the removable battery is rated for up to 40 hours.
Where they differ on paper:
- Battery Life: 18 hours (Manufacturer specified) vs 40 hours (Manufacturer specified)
- IP Rating: IPX4 vs None
- Drivers: 2x 6.5” woofers, 2x 25mm tweeters vs 2x 10” woofers, 1” silk dome tweeter
- Amplifier Power: 240W vs 216W (3x 72W)
The JBL Partybox Stage 320 stands out because handle and wheels are convenient. Watch for: slightly sibilant in the treble at full blast. Price runs higher too, $499.95 versus $449.
The Soundboks 2 makes sense for built for maximum outdoor output: Watch for: at 15kg it is large to transport, lacks weather protection, app EQ and TWS stereo pairing, and relies on an external charging arrangement. It’s the lower-priced option too, $449 against $499.95.
Buy the JBL Partybox Stage 320 ($499.95) for a party speaker; the Soundboks 2 ($449) suits a battery-powered PA speaker instead.
Water resistance is not close: the JBL Partybox Stage 320 is rated at IPX4 (splashing), well ahead of the Soundboks 2 at no water resistance.

Soundboks 2: $449.00 Discontinued eBay
Pros: Built for maximum outdoor output: its two 10-inch woofers and silk-dome tweeter reach a claimed 124dB, while the removable battery is rated for up to 40 hours. It also provides aux, microphone and guitar inputs, making it a practical battery-powered option for loud parties and informal performances.
Cons: At 15kg it is large to transport, lacks weather protection, app EQ and TWS stereo pairing, and relies on an external charging arrangement. Its tonal balance and bass depth are less refined than stronger modern party speakers, and this discontinued model requires caution around used-battery condition and support. Discontinued.
