JBL Partybox on the Go 2 portable bluetooth party speaker

Key Features and Specs

• Sound: Powerful JBL Pro Sound with 100W RMS output, featuring a 5.25-inch (135mm) woofer and 2 x 0.75-inch (20mm) dome tweeters for punchy bass, crisp highs, and clear vocals. Frequency response: 40Hz–20kHz (-6dB). Some variants (like the On-The-Go 2 Plus) add AI Sound Boost and EasySing features: real-time AI vocal removal from any song (for instant karaoke), pitch support, natural reverb, and app-based tuning via the JBL PartyBox app.
• Battery Life: Up to 15 hours of playtime (real-world often 12–14 hours at moderate volumes), a big improvement over older On-The-Go models. Includes a replaceable/swappable battery (sold separately for extended sessions) and USB charge-out for powering devices.
• Durability: IPX4 splashproof rating (resists rain or spills), rugged build with a convenient central handle and adjustable shoulder strap for easy carrying. Weighs around 9–10kg (about 20 lbs), making it truly portable compared to heavier PartyBoxes.
• Connectivity: Bluetooth 5.4 for stable pairing (up to ~30ft range), Auracast support for multi-speaker linking/broadcasting, plus inputs for mics/instruments. Comes with a wireless mic (or bundled in Plus versions for enhanced karaoke).
