The JBL Flip 5, Pulse 4, Boombox 2, Xtreme 3, and Charge 5 are all compatible with JBL PartyBoost.īeyond what the JBL Connect app offers is the Charge 5’s power bank functionality. If you want to sometimes use the Charge 5 by itself, set it as the secondary speaker. If you opt for Stereo Mode, the next time you play music from the primary speaker, it will play music in stereo through both speakers. Under Party Mode, all speakers will play audio in mono. You can connect two of the same speakers together to listen in Stereo Mode, or you can connect up to 100 of any compatible speakers together for Party Mode. PartyBoost is JBL’s tool that allows you to connect multiple speakers together for a louder sound. If you just connect two compatible speakers together, you can listen to music in stereo. You can connect up to 100 compatible speakers with PartyBoost. If you do happen to break the speaker within 1 year of buying it, JBL will send you a new one. This may also have been a result of the chlorinated water, since JBL does not ensure that its speakers can withstand saltwater or chlorinated water. In 2020, I tested a JBL Flip 4 that was out of warranty by submerging it in the pool and it subsequently broke, so it’s possible that the IP rating will degrade over time. The fabric covering the speaker will still get plenty wet, but once it dries everything will sound normal. Even after a firm dunk in a bucket of water, the Charge 5 sounds just as good as when it’s dry-just make sure the charging port flap is securely closed. The Charge 5 has an official IP67 rating, which means it can withstand dust and handle submersion in up to 1 meter of tap water for up to 30 minutes-this squares with our experience. Some people don’t trust the waterproofing that IP ratings promise, and we don’t blame them. The IP67 rating means you don’t need to worry about dirt and dust ruining your speaker.
