If you already make killer audio products, do you think spending $50 million on a headphone firm is a good idea? It is you're Logitech's management, which just cut a check for that amount to buy sports audio outfit Jaybird. Much like Ultimate Ears, Jaybird will remain an independent subsidiary of its new parent company, selling wireless sport buds. Logitech's interest may rest more on Jaybird's sport-focused wearable, Reign, which measures your heart rate variability during training. In a release, Jaybird founder Judd Armstrong says that his firm will "benefit from Logitech's global distribution network and engineering prowess."
