JBL Pulse 4 Waterproof Bluetooth Speaker with 360° LED Light Show - Portable Wireless Speaker for Pool Party, Beach & Outdoor Adventures (Renewed, Black)

I bought my JBL Pulse 4 refurbished, and I'm glad I did! It arrived in just a few short days (the seller used Fedex, so it was easy to track) in its original box and included its manual. Had I not known I bought a refurbished one, I wouldn't have been able to tell.I already had one Pulse 4 and liked it so much that I got this one to use for PartyBoost. It paired easily with the my other speaker and with my friends' JBL speakers with PartyBoost. It was great having surround sound with using PartyBoost with having 5 speakers connected, and when it got dark my JBL Pulse 4 speakers stole the show with their light show displays.Individually, the speaker sounds great and offers nice 360 degree sound. The bass is good for the type of speaker it is.The battery life stated on the box says up to 12 hours, but that is only probably reached with the light display turned off. The longest I've used it so far was about 7 or 8 hours, and I had the light display turned off for about the first 3 hours of use for that session. There was still battery life left, but it was time to pack up the party.
