> Overview Conclusion
Overview The Logitech Mobile Freedom offers a fairly standard design, with a rubber plasticized earloop that connects to a round earpiece with a stubby ear boom. The lightweight AC adapter plugs straight into the body of the earpiece, and you'll need to charge it for a few hours before first use. The Mobile Freedom is rated for a healthy 7 hours of talk time.
Pairing the device with the Treo is a painless process. The multifunction button is a black nub on the upper portion of the earboom. Holding this down for about ten seconds causes the LED to rapidly flash blue and red. Then to put the Treo into pairing mode, tap on the Bluetooth icon and follow the step-by-step on-screen instructions.
Design
The controls on the Mobile Freedom Headset are extremely simple and easy to use. The multifunction button is easy to locate and use while the earpiece is on the ear. A raised black nub allows one to answer the phone from the headset. The volume button is slightly different than others; the face of the unit is a raised circular portion that works like a simple rocker switch. Press up to increase volume, down to decrease it. It also is easy to find and use with one hand.
The designers of the Mobile Freedom seem to have been going for simplicity all though the headset. The earloop is a simple rubber affair and can swivel on two axles—one towards and away from your head and the other perpendicular to that rotating around the earpiece. This combination makes for a simple way to adjust for comfort and fit.
In line with this design philosophy, the earpiece speaker is very large and covered with foam designed to gently rest against the ear. The boom mic is short, stubby, and unobtrusive. The tip is covered with textured foam to distinguish the mic from the smooth dark gray plastic of the rest of the device.
Functionality
The design theories behind the earpiece seem to be better in theory than in practice. I could never quite get a satisfactory fit where I didn't feel the unit was going to stay firmly where I had placed it. The main problem is that the earloop is a bit floppy. I wish it had the ability to bend into a tighter fit. Under calm conditions, the earpiece does stay in place, but while moving it wiggles too much for my comfort.
The earloop easily rotate and swivels for left or right ear use. So if you're a person who uses the earpiece alternatively often, than this would be a desirable feature.
Sound Quality
I've had very mixed results with the sound quality on the earpiece. Like many (but certainly not all) Bluetooth headsets I've tested, the audio quality seems to depend upon the position of the stars and the moon. Or maybe it is just the amount of wireless interference that I seem to get. No matter, the result is the same. Sometimes a lot of crackle and hiss, sometimes less. Never does the headset reach optimal quality. Logitech touts a feature called WindStop. Ironically, I found that in a heavy wind the earpiece physically blew around too much.
