It’s unlikely that the Jawbone Jambox will be shoved off its throne anytime soon; not necessarily because it’s the best-sounding portable Bluetooth speaker out there, but because it was here first, and it made a huge splash (in part because, yes, it sounds pretty good).

But I were to bet on a challenger, I might put my money on the smart new UE Boom. Not only is it ruggedized against drops and splashes, but it’s armed with two very unusual tricks.

Noise-cancelling headphones are suddenly all the rage. It certainly seems as if every big player in the audio game has at least one model that features active noise-canceling, usually accompanied by other luxury features — and with a corresponding luxury pricetag. Even manufacturers who’ve only recently begun making cans, like Logitech UE and Klipsch, prominently feature active noise-canceling in their model lineups.

It may even seem as if the technology has been added to some models simply because it’s become the feature du jour — an impression strengthened by the fact that not all noise canceling is the same. Not even remotely.

None of the headphones in our showdown — the Klipsch Mode M40 ($350), the Logitech UE 6000 ($200) or the Monster Inspiration ANC ($300), the noise-canceling version of the regular, passive Inspiration model we reviewed last year — exhibits the powerful noise-canceling ability that can almost completely drown out noise, like that of the Bose QuietComfort 15. Nor do they sit on the next level down, with NC performance similar to, say, Audio Technica’s ATH-ANC7b (although one here comes close).

We’re very stingy with our five-star ratings, and it’s even more rare for us to slap all five onto a gadget.  So pay attention — because today we’re awarding the full five stars to the Logitech UE Boombox ($250), a portable, battery-equipped, eight-driver Bluetooth speaker that sounds absolutely astounding. In fact, the Boombox does a better job of rocking out than some non-portable, home systems costing much more.

So far it’s been pretty consistent: Each time we review a set of Ultimate Ears ‘phones, the bar leaps up a few notches as our expectations regarding the outfit’s offerings rise. After reviewing the 350, 700, and especially the 600vi — which garnered a best-in-class verdict — we were expecting the TripleFi 10 ($400) to slay vampires and cure cancer.

Of Ultimate Ears’ more serious offerings — and by serious, I’m referring to UE’s armature-equipped models, which start at $100 — the TripleFi 10 is by far the most serious, with three drivers and a crossover in each ear, pro-level detachable leads, the thickest cable we’ve ever seen on an IEM, Comply foam tips (the best tips, period) and a sound signature that’ll have you madly running through your entire music catalog with a big, gleeful smile plastered all over your face.
