Excerpt: For the most part, Logitech’s 2008 acquisition of leading canalphone maker Ultimate Ears appeared to be quite successful—Ultimate Ears continued to create new high-end “custom fit” earphones, and considerably improved the designs of its more affordable “universal fit” models, each remaining at or near the top of their respective categories.
Conclusion: The expensive Logitech UE 900 earphones aren't perfect, but balanced audio performance and a generous assortment of accessories sweeten the deal.
Pros: Strong audio performance at moderate listening levels. Built-in controls and microphone for iPhone. Cable is removable, and ships with an extra. Sturdy carrying case includes several extra eartips, ?-inch plug adapter.
Cons: Slightly overpriced. Distorts on deep bass tracks at maximum volume. Can be slightly uncomfortable over long listening periods.
