Calling all mobile DJs, karaoke enthusiasts, musicians and party goers. The new Soundboks 4 simply delivers massive sound with an amazing battery life, all while looking great and integrating with the rest of the Soundboks product line.

I’ve taken this thing everywhere, including backyard BBQs, rehearsal spaces, parties with friends, and more, and I’ve never once found myself without a battery. The company claims a battery life of 40 hours (on medium volume, about 6-8 hours at full volume) depending on volume and usage, but I honestly only used it in bursts of 4-6 hours. However, it felt like I never had to charge it while I was using the speaker. The little lights on the side of the battery give a nice visualization of how much charge is left, and you can use the charging cord to charge and play the speaker at the same time.

Okay, so it wasn’t a rave per se, but an outdoor dance party, complete with a laptop DJ. The setup was a breeze, with the laptop able to connect via Bluetooth and play music from any available DJ app (or streaming service). The sound filled the immediate area and could be heard absolutely everywhere in the park. The bass was thumping, the treble and mids were crisp and clear and (depending on the audio track) had great clarity too.

I also took the Soundboks 4 to a friend's karaoke party and used it via the aux jack to amplify the sound from their karaoke machine. Being able to add a microphone to the pro XLR input on the back of the speaker (you have to adjust the mic volume in the Soundboks app) and just sing really made adding a microphone to the mics built into the karaoke machine a breeze. What a great addition to the party.
