JBL Partybox 300 Review | 130 Data compared

The Gadgeteer review of the JBL PartyBox 300 highlights a powerful Bluetooth speaker featuring dual 6.5-inch woofers, three 2.25-inch tweeters, and dynamic LED light modes. Key advantages include massive volume output, extensive connectivity options like mic/guitar inputs, and an 18-hour battery, though the speaker's 35-pound weight makes it less portable and maximum volume drops when not connected to AC power.

The Gear Diary review highlights the JBL PartyBox 300 as a powerful, feature-rich speaker for large gatherings, showcasing boisterous JBL Signature Sound, reactive light shows, and dedicated 1/4″ inputs for microphones and guitars. While the 10,400mAh battery provides up to 18 hours of playtime, the speaker is hindered by a heavy, 35-pound design, a lack of IP-rated waterproofing, and reduced sound volume when operating off AC power.

The PCMag review of the JBL PartyBox 300 highlights it as an incredibly loud, portable Bluetooth speaker featuring impressive bass, versatile mic/instrument inputs, and an integrated LED light show. While offering robust, rugged design and powerful audio, the speaker is criticized for its high price, long five-hour charging time, and lack of included audio cables or an XLR mic input.

Trevor Long’s review on EFTM highlights the JBL PartyBox 300 as a high-value, "all-rounder" Bluetooth speaker, delivering massive sound through dual 6.5-inch woofers and featuring versatile, customizable light modes. While praised for its impressive 18-hour battery life and competitive $599 AUD price point, the speaker is described as a heavy "monster," representing a significant, less-portable footprint. E

The JBL PartyBox 300 is a loud, large party speaker featuring an 18.3-hour battery, flexible positioning, and dedicated microphone/guitar inputs for karaoke. While it maintains clean, punchy audio at high volumes with minimal compression, it suffers from underwhelming low-bass extension, recessed treble, and lacks a companion app for EQ customization or, unlike newer models, an IP rating.
