Open headphones aren't that loud at all. Others will notice if you're cranking it. Medium volume to you will sound quiet to someone five feet away.
 
If your office is really noisy, you might be dissatisfied, meaning the noise will interfere with your audio experience, but I'm sure since you're using this in an office setting, you're not going for that full audio-nirvana experience anyway. It might even be better for your situation because you'll be able to hear your co-workers when they need you, since there isn't a seal at all.

 
You've pretty well summed my thoughts on the matter at the time of purchase.  I need to be able to hear my coworkers.  I can't listen at concert levels....
