Hi - Anyone know of good laptop speakers that don't need charging through my mac- my last speakers made streaming tv programmes difficult as the signal keeps cutting out and what with charging the speaker it crashed my applemac. Probably need one that doesn't charge thru the pc and no bluetooth? Wired speaker? Can anyone help, especially as the sales are on. I can pay around £50. I should say I also play music on the mac- it doesn't need to be massively loud. Thanks!
