Got a third-generation iPod nano? Looking for a new set of earbuds, preferably with noise-canceling abilities? If so, look no further than Radius' new set, which plug right into the dock in order to extract all the juice they need to block out extraneous clamor. The radStrap canalphones are expected to ship in black, green and silver, and feature a neck strap, on / off switch for the noise-cancellation, an aluminum housing and frequency response of 20Hz to 20kHz. Check 'em out next month for ¥8,980 ($82), but don't get your hopes up for a bonafide US release.

We've got Bluetooth headsets that cancel noise, amplify voices, and make you look good not entirely cockamamie, but Sound ID's latest iteration actually gives you one less reason to ever take it off. The minuscule earpiece sports compatibility with handsfree Bluetooth profiles, around eight hours of talk time and 72 hours of standby, auditory and visual low battery warnings, dual omni-directional silicon microphones, and a trio of modes to fit your situation. It also touts a NoiseNavigation feature that magnifies and cancels appropriate sounds automatically, and just in case you get tired of only hearing face-to-face conversations out of one ear, the "Environmental Mode" actually brings in ambient noise in order to make you forget about the critter hanging off your eyeglass holder. Notably, the $129.99 SM100 even features a One2One mode that enables "Bluetooth communication between two modules" without the use of a cellphone, which should definitely appease the anti-social social crowd.

If Gennum's nXZEN Bluetooth headset with noise cancellation caught you eye last year then check the evolution, son. The nX6000 adopts a new design, Bluetooth 2.0, and mini-USB jack yet drops the weight considerably from 17-grams to 10.9-grams. Their FRONTWAVE Extreme noisecancellation is combined with digital voice isolation technology and dual-microphone array that isolates the user's voice from the ambient noise. The headset features 6 hours of talk time / 90 hours of standby and accepts a recharge to its Lithium Polymer battery over USB.
