A:AnswerNo, the JBL Pulse 3 does not pair with the JBL Pulse 2 because the Pulse 2 used the original JBL Connect, while the Pulse 3 uses the new JBL Connect Plus.
A:AnswerThe $169 price was a sale over the holiday, you will not be able to buy it at that price until there is another sale on the product. To determine when it will be on sale again is improbable.
A:AnswerOne single JBL Pulse 3 will most likely not be dominant over even 50 people. The JBL Boombox would give a good submersive sound for a group that size, Although is has a much higher price than the Pulse 3, at $449.99.
A:AnswerHi! The USB charging adapter is the one that determines the voltage rating of it, not the Pulse 3 since the charger is the one that converts the voltage to the right amperes needed to charge the speaker. Most USB charging adapters today are rated at 110 to 220 volts. Make sure you check the charger to be sure.
