Bose plays over 12 hours at regular listening levels. 6-8 hours is what you need to get at levels close to optimum.
You are able to usually use it outdoors within the garden exactly where i generally need to turn it a little louder to be able to drown background noise and also the longest i got was 14-15 hours.
The bass will be the most outstanding component from the soundlink, the large jambox is 30% bigger but does not generate that quantity of bass but however the large jambox sounds clearer with treble and mids, so it’s just a matter of taste. as i mainly use the speaker outdoors the powerful bass is really a large plus because the soundlink sounds truly potent even with out any reflecting walls whilst most other speakers have a tendency to sound shrill in the event you listen to them within the open field.
If protability is essential for you personally, i’d go for the soundlink, it’s not larger than a book, the jambox is fairly a “fat” box currently, whilst i can even fit the soundlink even inside a larger jacket-pocket.
