Best small 2.0 laptop speakers.

Hi,

I need advice. I'm looking for speakers for my laptop, but I can't find anything that I actually like.

I care about 3 things:

-Sound quality - I want something really good. I listen to variety of genres so something quite neutral in terms of sound.

-Size/portability - I want something as small as possible. Something that doesnt take up too much space in my carry on and doesnt have a massive power adapter.

-Design - good design. something that will survive on the road. no fancy exposed speakers, weird shapes or glass elements please.

Less than $500
