Wideband audio codecs have become nearly standardized in the IP communications field in the last few years. With the "more for less" quality vs. bandwidth needs, high-definition and low-bandwidth codecs are in high demand.
Garrett Smith, on his blog, "Smith on VoIP", posted an interesting interview with Polycom Co-Founder, Jeff Rodman. In this interview, Rodman discusses the importance of high-definition codec development, and also outlines Polycom's HD Voice strategy.
Rodman states:
The benefit of wideband audio is obvious, especially once you hear it. Remember that everything we hear today, from satellite and FM radio, to records and CD’s, to television, and even our oven timers, is already wideband audio. When we have a drink with friends or sit around a table with our co-workers, our voices are HD Voice, our ears are accustomed to hearing the whole speech spectrum. It’s only the phone, which is one of the most critical tools in business, which has become the last holdout of poor audio.
Polycom is not the only telephony endpoint company to develop and market high-definition-codec-capable phones. Snom's recently-released 820 features wideband audio support as well.
Look for more companies to provide high-definition audio support in the future. As always, there will be some questions about interoperability between vendors and platforms, but for homogeneous environments, rolling out wideband audio support on an existing platform can be as simple as a software update, provided that hardware support is available.

Yes yes, I have also heard
Yes yes, I have also heard about them. Are they so good as they are said to be?! If so, I just have to grab some because I am in really need of such things.
