CES 2024 Lasting Impressions: The Highlights

CES2024 was the best in a long time. I said that in my First Impressions article, and as we distance ourselves from the whirlwind of those hectic six show days, the stronger that feeling grows. And one of the reasons has to do with the fact that important technologies are already making a difference in the audio products that we will soon see in the market - while many others are about to. And there are clearly companies that left us with very positive, lasting impressions that we can and need to share.
