Which headset / headphone for work?

[todor]

Use:
1. Listen to music while working
2. Talk in video/voice conferencing

Here are my requirements:
1. Wireless
2. NOT totally blocking sound coming from outside (remember, I am at work, I need to hear colleagues trying to hail me)
3. Keeping my music in (don't want to disturb colleagues)
4. Decent microphone. Ideally would like one that's flush but no problem if it's a handle-style microphone
5. Comfortable for long-time use
6. Decent battery
7. Not too expensive (under 200)

If you have any ideas or maybe you have something like this that you are happy to recommend - that would be great!
