Already got speakers (literally anything with a headphone jack) and don't want to shell out for a new wireless sound system? Beep is the gadget for you. It plugs into your existing speaker and connects via Wi-Fi to your smartphone. It only works with Pandora or Spotify for now, but Beep promises more apps are coming soon.
