While I was recently shopping at BestBuy for a wireless music speaker, a salesperson who arbitrarily remarked that Bose was the best got me thinking about pilots shopping for premium aviation headsets, a market dominated by Bose and also Lightspeed for as long as I can remember. While Bose may be the most recognizable name in both the consumer audio and aviation headset markets, don't forget that Lightspeed Aviation was a major force in shifting the market from passive to active noise cancelling headsets in the early 1990s.
