Here's a relatively new Windows Phone accessory that jumped off the computer screen at me. The RF3 ENVi corded headsets use AirCom2 technology to keep potentially harmful radiation away from your noggin'. Using natural wood earpieces is another feature that makes these corded headsets unique.
We took a look at the Mono-earphone model (comes in a two piece stereo model as well) and the RF3 performed really well. The ENVi headphone does approach things a little differently than your typical corded headset. Typical headsets send the audio signals through wires directly to a speaker that sits in your ear. The ENVi uses a SPL enhanced sound chamber that then channels the sounds up air tubes to a natural wood earbud. It basically puts the speaker down from the earpiece.
The build quality of the headphone is good. The wood pieces feel solid and to help with the fit/feel, the earpiece comes with a few different sized earbuds. A wired ear hook attaches to the wooden speaker to help with a secure fit. The downside to the ear hook is that is right ear only.
A microphone with switch rests along the wired section of the cord that you can use to answer/end calls. Call quality and audio quality was really nice. Granted this is a mono headphone but still the audio quality was surprisingly nice. Especially when you consider the last six inches of travel is through a hollow tube.
The only oddity, and I use the term loosely, is that the headphone isn't fitted with a 3.5mm headphone jack. Instead sports the smaller 2.5mm jack. To balance things out and save you from having to hunt down an adapter on your own, the headphone is packaged with a 2.5mm to 3.5mm adapter.
The RF3 ENVi collection includes the mono earpiece with or without the hook and a stereo headset with or without the ear hooks. The headphones start at $29.95 and top out at $44.95. You can find the mono earpiece with hook here and the entire RF3 collection here at the WPCentral Accessory Store.
