A long time ago, before this site was born, we reviewed the Altec Lansing BackBeat 906 Bluetooth headphones, and liked ’em. Plantronics had their own identical version of the 906, as they had owned Plantronics since 2005 (the two companies parted ways about the time the 906 was released).

The Plantronics BackBeat Go ($100) is an evolution of the 906. Same principle — wireless (meaning there’s no wire conecting the player with the headset) music and calls in a compact form via the magic of Bluetooth — but in an even smaller and more svelte form factor. Should be even more fantstic, right? Let’s take a look.

Sennheiser’s VMX 200 is one kostspielig little Bluetooth headset. Its $150 MSRP is higher than the other guys’ flagship mobile-phone headsets, like the Motorola CommandOne, Jabra Supreme and BlueAnt Q2, all of which are good-to-stellar performers, and stuffed to the gills with features.

Taking the pricing into consideration, one might expect the VMX 200 to have near-perfect manners, and at least as many bells and whistles as its competitors, if not more. Right?
