For my 2011 MBA 11" (which I really like!), I connect it to a 24" monitor when at my desk along with the power connector and a USB hub (so 3 connections each time I use it in a desktop setting). I'd like to find a good set of USB speakers that I can connect to that hub basically just to avoid a 4th connector each time I use the MBA at my desk. Are there any recommended options out there? Budget-wise, I'd like to target between $20-$75 and no subwoofer (just a decent speaker pair with good sound). Thanks!
