-quality of incoming calls
Good. Obviously depends on your connection quality but the mono speaker in your ear is load and the volume controls easy to use whilst driving.

-quality of outgoing calls (outdoor, windy and indoors in crowded places)
The annoying thing about the roadrunner is that it is bl**dy difficult to find the right positioning for it to pick up your voice. When the throat mic is at the correct spot – it works brilliantly where people I am calling can’t believe I am on my handsfree however if you don’t find that sweet spot then it varies from people hearing nothing but garble to your voice sounding like a robot. There is however nearly zero background noise. I’ve used it with the top down on the motorway. The roof up and music blaring.

-how well it fits on the neck and in the ear and under a helmet (ski, motorcycle)
It fits around the neck easily (You need to order one for your neck size).
I can’t comment on using it with a motorbike helmet.

-how comfortable is it when wearing for hours
The longest I’ve worn one is on a 2.5 hr journey and I didn’t feel any discomfort.

-battery
It’s given 2 weeks of light use without needing a recharge (Used for about 2 hrs per day with only about 30 mins of actuall calls per week)

-voice command recognition (ideally with Nokia N95)
I’ve paired it with my HTC TYTN and been able to use the windows mobile voice dial/command. I’ve not had any issues but I only have 4 voice commands programmed in and they’re all quite different (eg. “home”, “voicemail”, “work”, “tomtom”) so its not the greatest of tests.

Conclusion: the fact it is tough to find/position the throat mic to the “perfect” place makes me give it a thumbs down. I simply can’t spend 5 minutes prior to each journey calling myself to see if I have it positioned right.
