If ever a product was made for dads… Sony’s MDR-NC6 over-the ear headphones can reduce “perceived” outside noise by more than 70 percent (up to 10 dB at 300 Hz). The concept is the same as the more expensive versions, a circuit senses outside noise via the built-in microphones and sends an equal-but-opposite canceling signal to the speaker. Light, foldable, and now even cheaper, these make a great commuter accessory. Powered by one AAA battery, they will do their job for approximately 30 hours. This year, give dad what he’s been asking for, some %&$#@ peace and quiet.
