JBL Pulse 4 Portable Bluetooth Speaker – IPX7 Waterproof Wireless Party Speaker

Sometimes we just can’t be bothered going out to a club just to enjoy some party songs. Maybe we just don’t feel like going out to the club that night, or maybe we are too tired from a hard day at work/college, or ultimately, we might just prefer to stay at home and have a smaller and less noisier party that we can enjoy with family and/or friends. And that’s where having a portable party speaker like the JBL Pulse 4 Portable Bluetooth Speaker comes in handy.

With the JBL Pulse 4 you can kick start your party with JBL’s signature sound, which comes accompanied by a dazzling LED light show all in 360 degrees.

While its waterproof design makes it great for pool parties, its rechargeable battery keeps the tunes flowing as well as its shiny, bright light show going, both staying alive for up to half a day on a single charge.

Via the JBL Connect App users can easily change the JBL Pulse 4’s sound-responsive colors and patterns, as well as connect it with any other JBL PartyBoost compatible speakers to make their party an epic one to remember.
