Ayra — A tiny, EXTRA loud portable speaker

How does this compare to say Jawbone's Mini Jambox? I usually bring two of those with me with traveling (they can play together for extra good sound), but always interested in exploring something else if it's smaller/better.

I have recently started keeping an Ayra in my carry-on suitcase and you would not believe how many times I have used it in the most random travel situations. The Ayra goes especially well with mini-bar treats. It's like a miniature party with exceptional sound quality.
