Audio and Portable Power

Reviews and guides covering headphones and portable power together: noise-cancelling headphones for travel and work, kids' wireless headphones (where volume-limiting is the feature that actually matters), and power banks for travel and emergencies.

Kids' headphones get their own guide because volume limiting is frequently marketed with a single decibel number that doesn't tell you how the limiting actually behaves in practice — whether it's hardware limiting (a physical cap built into the headphones) or software limiting (controlled by the source device, and easy to lose if a child switches devices) changes how much the advertised number is actually worth relying on.
