THE VERDICT
SDA-Pro, the latest refinement of Polk Audio's proprietary tech, elevates the performance of its impressive flagship speaker.

Many years ago (the early 1980s, to be precise), Polk Audio produced the first speakers to feature a technology it had developed called SDA (Stereo Dimensional Array). The idea behind SDA was to eliminate a problem called interaural crosstalk that's a necessary artifact of typical two-channel speaker configurations. Basically put, when listening in stereo, your left/ right ears hear not just sound emanating from the respective left/right speakers, but sound coming from the other speaker as well. According to Polk Audio, this has a constricting effect on the presentation, with the width, height, and depth of the stereo image coming across as a pale representation of what's actually contained on the recording.

Ultra HD's, however, appear to be fighting the trend. UHD re-releases of popular films are showing up like flies to a picnic.

THE VERDICT
Charging becomes a secondary concern with Cleer’s Enduro 100 wireless headphones thanks to an insanely long battery life.

I’ve been listening on and off for six days and the tiny battery in Cleer’s Enduro 100 wireless headphones is still going strong. Impressive. No question, headphones that need frequent recharging are…well, annoying and intrude on the freedom that comes with wireless listening.
