As with anything electronic there is always some kind of race; mega pixels on cameras, storage capacity on MP3 players and so on. When it comes to IEMs, the race has been about putting more and more armatures into already cramped earphones. No doubt there’s a lot of marketing aspects behind this, but that doesn’t mean it’s not about getting better sound – specially when you step up a few price ranges.
The Ultimate Ears UE11 Pro is the latest wonder in IEM technology, packing four separate speakers in each earphone – among them a sub woofer. The reason behind this method is to provide a different armature for each frequency range and thereby providing more real sound. Popsci.com has made a great “how it works” feature explaining how this technology works and why it’s as good as they say. Hit the link for the full feature.
