When one company swallows another, it’s common for a slow shift in rebranding and design to occur as the two entities thrash out their roles and relationship. The latest shift in the Logitech-Ultimate Ears story — Logitech purchased UE in 2008 — occured a month or so ago, when Ultimate Ears was rebranded as Logitech UE and launched a suite of high-end, blue-tinged soundware, with a product selection that reached far beyond the in-ear monitors the company has thus far been known for. In fact, out of seven new gadgets, just one new IEM was introduced: the Logitech UE 900 ($400), a quad-armature earphone that now sits at the pinnacle of UE’s non-custom earphone line.

The UE 900 has lineage, of course; we loved the snug fit, solid build and amazing sound of its antecedent, the TripleFi 10. But the TripleFi 10 is gone, and the UE 900 has stepped into its place with new ergonomics, a new sound — and a lot of blue.

MDR-XB800

There isn’t anyone with a model catalog quite like Sony (how the hell do they keep track of these things?). The company has just refreshed their line of midpriced, bass-heavy MDR-XB headphones with three new models, replacing four previous ones.

The three new models, the XB800 ($150), XB600 ($100) and XB400 ($60), all follow Sony’s headphone design template: soup-bowl sized, perfectly circular cups attached to massive headbands (the headband on the XB800 is so formidable it looks like it could maybe double as a helicopter landing strut).

I remember saying something to the effect that these Monster Inspiration headphones (passive noise isolation, $300) looked like fluff when I first encountered them at the Consumer Electronics Show earlier this year. Boy was I wrong.

Denim never looked better.

Discovering great headphones from a company that specializes in making bags was surprisng at first, when we reviewed Incase’s Sonic headphones late last year. A month later we were less stunned when we grunted in approval at their Capsule in-ear ‘phones during our budget(ish) canalphone shootout.

This time around we played with a new denim-clad version of the on-the-ear Incase Reflex headphones ($80) — which sit between the $150 over-the-ear Sonic and the canalphone Capsules — and came away with the impression that the Reflex may very well be the best bang-for-buck of the bunch.

You’re an American, and you’ve just watched your athletes come away with a barrel full of gold medals in London. Maybe you’re feeling a little patriotic; maybe a little like you want to go out and train for Rio de Janiero. If so, then Monster has created the perfect earphones for you: A special edition “USA” version of their impressive, washable, iSport IEMs.
