How do I check if my JBL Go 4 is original?

Look for clean printing, a serial number and barcode stickers on the box, then enter the serial on JBL's authenticity checker. A listing priced at a few hundred taka is almost certainly a copy.

What is new in the Go 4 compared with the Go 3?

Reviewers note longer battery life, Playtime Boost, Auracast and app support on the Go 4, with a similar 1.75-inch driver and the same IP67 rating.

The JBL Go 4 is JBL's smallest portable speaker. It fits in a palm and clips easily onto a bag. A 45mm driver delivers 4.2W of JBL Pro Sound, and Bluetooth 5.3 keeps the connection steady. Auracast lets you pair it with another Auracast-enabled JBL speaker for bigger sound. The IP67 rating means it is dustproof and can survive a drop in water, which helps on a rainy rooftop or a beach trip to Cox's Bazar. JBL rates the 850mAh battery at up to 7 hours, plus up to 2 more hours with Playtime Boost. It charges over USB-C in about 3 hours. Counterfeit Go 4 units are common on marketplaces at a fraction of the genuine price, so check the serial number on JBL's authenticity page. Pay with Cash on Delivery.
