After a detailed research bought this as a gift. I am already using the original JBL GO for more than 2 years and am really impressed with the output. Hence had a peace of mind while buying this. The GO 2 is a good product and highly portable. Its is fairly loud and has a decent amount if bass (while nothing as compared to the higher models of JBL / Sony / Bose).
In a nutshell if you are looking for a great speaker within the 2k bracket, which is portable and produces good sound quality, then this is the product for you.
