Consensus

our Verdict

Top experts love the JBL PartyBox 300, and they endorse it for parties, music, and podcasts. Testers at PCMag lauded its excellent 18.3-hour battery life. Experts at The Gadgeteer praised its dual-device Bluetooth pairing, although the 198 ms iOS Bluetooth latency and 176 ms Android Bluetooth latency were high. Testing revealed a very loud 103.3 dB maximum SPL and very low 0.33 dB DRC, so it maintains the audio quality very well even at the highest volume. Reviewers liked its mic/guitar ports. They adored its 55.0Hz to 18.0kHz frequency response range, and the 3.37 dB standard error shows a well-balanced sound profile. However, it has a high 6.71 dB directivity index, featuring a poor soundstage, although it supports stereo. See our JBL PartyBox 110 review if you require a wider soundstage. The PartyBox 110 doesn’t have voice assistant features or an EQ. Weighing 35.1 lbs during testing, this system is not portable, although it has wheels, and it’s not water-resistant.

  • Speaker gets very loud and maintains audio quality at high volume settings
  • Customizable RGB lighting

  • Well-balanced sound out-of-the-box
  • Dual-device Bluetooth pairing

Reason to Avoid

Featuring an IPX4 water-resistant rating, the JBL PartyBox 310 is more suited to the outdoors than the JBL PartyBox 300, which is not water-resistant.

With a loud 103.3 dB maximum SPL and low 0.33 dB DRC, the JBL PartyBox 300 gets louder with less sound deterioration than the Sony XP700, which has a 99.0 dB SPL and 3.39 dB DRC. However, the Sony speaker has better low-bass and comes with an EQ for customizing sound profiles, unlike the JBL speaker.

The JBL PartyBox 300 has a 0.33 dB DRC, featuring much fewer sound compression artifacts at its highest volume than the SOUNBOKS Gen. 3, which has a higher 6.95 dB DRC. However, the SOUNDBOKS speakers offer a much better 43.8-hour battery life than the 18.3-hour runtime of the JBL PartyBox 300 speaker.
