It’s 4:30 a.m., and European football is on. Or maybe it’s the diving semifinals broadcast live from the Tokyo Olympics. Either way, the screen on your phone or laptop is just too small: You need a TV. But keeping the sound of the big screen to yourself—especially as a courtesy to a sleeping partner—can be surprisingly challenging. Most manufacturers see TV headsets as an unsexy category that’s not worth the effort, and the sound provided through built-in solutions like basic Bluetooth can lag behind the picture. The $280 RS 175-U from Sennheiser Electronic Corp. is still the standard-bearer: It operates with no discernible delay, even through walls, so you won’t miss the action when you head to the kitchen for another coffee.
