There are a lot of neckband-style headphones out there right now, but V-Moda's Forza Metallo Wireless is definitely worth checking out if you're looking for top-notch sound and solid build quality coupled with a secure, comfortable fit in a workout-friendly Bluetooth headphone.
At $170, it's not cheap, but from a sonic standpoint, it's superior to theand most in-ear wireless headphones I've tested, including LG's around-the-neck Tone headsets. (The headphones aren't available in the UK and Australia yet but that price translates to about £130 or AU$230.)
As with the wired versions of this headphone, which we liked (you can read CNET contributor Steve Guttenberg's assessment), it's easy to get a secure fit using one of the four included ear tips and V-Moda's well-designed, patent-pending sport fins keep that tip snugly in place, sealing out a lot of ambient noise.
You don't have to use the sports fins but I kept them on at all times, whether I was working out or just walking around. And yes, this headphone is sweat-resistant and you can run with it for long distances without a problem. The only downside is that it's got a noise-isolating design, so you'll have some trouble hearing traffic around you, which some runners and bikers consider a safety issue.
Battery life is decent at 10 hours and the headphone works well as a headset for making cell-phone calls. It may not quite be business-class performance -- there's no noise-reduction feature, for example -- but callers said they could hear me fine and I appreciated that the headphone vibrates when a call comes.
The battery and most of the electronics are stored in a module that's designed to sit on the back of your neck. Occasionally that module slid down between my shoulder blades, but overall the headphone is weighted pretty well and you'll barely notice you're wearing it when the earbuds aren't in your ears.
