Raves:When used as a headset for Skype, the microphone is surprisingly effective. Sound quality is much better than with tiny in-the-ear devices.Comfort and battery life is also excellent -- I charge mine overnight and wear it all day long.Cautions:Extending and retracting the adjustable headband should be done with care. I pulled mine out a little too quickly once and it came apart. Fortunately, nothing was broken and I was able to carefully reassemble it with no harm done.When pairing, it helps to hold the headset within a few inches of the PC bluetooth antenna.Rants:The "Features" list includes "Wired connection for use with all stereo MP3 players." However, the cable necessary for this to work is not included. To be fair, it isn't listed in "What's In the Box", either.Range is a little disappointing. I bought a class-1 bluetooth adapter hoping that it would help, but I'm still limited to two walls indoors and about 100ft outdoors.
