They are compact, sturdy, use 1 USB connection and have software or firmware built-in that provides beautiful, echo free sound. In fact, we turn off AEC software when we use an ECM, so that the sound doesn’t go through two rounds of echo cancellation and introduce an unnatural latency into the conversation. The only problem is that ECMs can get sort of expensive, if you have a lot of endpoints. Moreover, if you video conference from a cubicle, having a speaker “sharing” all your video conversations may not be the ideal solution. So, for the cost of a couple lattes…
