In this video I compare the differences between 2.7 and 3.0 firmwares with sound clips and frequency graphs. #jblcharge4 #jbl #charge4 buy online: JBL Charge 4: https://geni.us/jblcharge4 Charge 3: https://geni.us/jbl-charge3 flip 4: https://geni.us/jbl-flip4 JBL xtreme 2: https://geni.us/jblxtreme2 tracks: Lost in Your Eyes (feat.
