From these fellas:

I bought them for a 6 day tour on the bike which I finished last week. Also for tunes in the garage when working on the bike, kitchen etc.
The speakers worked a treat, pack thin and come in a protective neoprene sleeve. The feel pretty robust for what they are. The remote that comes with it is "ok" but it was more of a bonus point for me.
There are smaller solutiuons but I wanted something that put out decent sound and this fit the bill for me.
