I know someone from work who has it, I would not get one my self but I'd recommend it.

Does not although improve sound quality, it's the same sound quality that comes out of the speaker but highly amplified.
 
I saw it in action and it worked. I ordered one last night for my iPhone so I can listen in the bathroom while showering.

You could get a cheaper alternative, but aren't we all about the docks? I considered ordered the SoundClip one for travel though.
 
It's not bad for on the go purposes. It works fairly well, but definitely nowhere near the level of a dock/speaker.
