Wireless loudspeakers are propagating at a remarkable rate. The first appeared in the 1990s, and received music signals from the source components via RF. But they sounded pretty awful, and didn’t catch on. The next wireless speakers used Bluetooth, which have gradually become better as Bluetooth’s codecs have improved, from SBC to aptX to the new aptX HD. Lately we’ve seen a proliferation of wireless speakers that work via Wi-Fi; these are easy to implement, as most people’s homes now have a wireless network. Apple, Google, and Amazon are the latest and biggest players in this market, with voice-activated products that also play music.
Some of the fabled audio brands of my teen years, in the 1970s, seem to be aging even less gracefully than I am as they face brutal competition from online merchants and low-cost Chinese brands. Sure, established names like Sennheiser can still command a premium over such brands as Fleeken, Hiearcool, and Paww. But when consumers can choose between OK headphones for $70 and name-brand cans for $350, most will likely cheap out. I’m guessing this is why Sennheiser has introduced the HD 4.50 BTNC noise-canceling Bluetooth headphones for $199.95 USD -- half the price of their next-least-expensive current models of this type, the PXC 550 Wireless and HD1 On-Ear Wireless, both at $399.95.
