I have one of these while my husband has the Bose Soundlink. We did side-by-side comparisons, and I found the Bose to be better sounding for bass-heavy music. All the really deep bass (like club music) came out slightly better in the Bose, but all the higher music (pop), podcasts and phone speakerphone sounded much clearer on my Big Jambox. I would say try to compare them based on how you want to use it, but I would say this is a fantastic choice. Plus the styling is so much better on my Jambox. I'm very happy with it.
I take this thing everywhere! It is unreal! no one thinks that this little speaker can produce this sound! I have had the bose sound link and i think the big jambox is more portable and overall a better buy! I recommend this to anyone looking to have a good time! Great for parties!
