So you’ve got your new iPhone 4S, and now you want to talk to Siri (and maybe friends) and enjoy some tuneage. Step one: Donate those pathetic white buds that came with your iPhone to your favorite charity, if they’ll take ’em. Step two: Get yourself a snazzy pair of microphone-equipped canalphones — earphones that fit snugly in your ear. Why? Because a good set of canalphones are the best accessory ever made for an iPhone; they’ll create a seal that will block out ambient noise while enhancing sound coming from the earphones, especially bass — which means better conversations with friends (or Siri), and better music.
Around $100 seems to be the point at which there’s a big jump in quality; also, most in that range are now equipped with inline volume controls (in addition to the play/pause and track-skip controls like the ones on Apple’s stock buds).
We’ve assembled an Apple Store’s worth of canalphones at that level, and we’ll be reviewing them over the next several days. Up first is Sennheiser’s MM 70 iP earphones ($100).
