Executive summary is:

  • The interference affects the amplifier, not the speakers or the cable (most computer speakers have the amp built-in to one of the speakers) so the solution is a well shielded amplifier.
  • Cheap solution is DLO Portable Speakers for iPhone (Apparently these are now distributed by Philips)
  • More expensive solution is Sonic Impact T-Amp with high sensitivity (90dB) bookshelf speakers
