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.
