Relative newcomer Nox Audio has just released its second headset, the earbud Scout. It follows up on the over-the-ears Specialist we reviewed back in the summer, and uses a balanced armature design to deliver what Nox claims to be strong bass, balanced mids and clear highs. The earbuds have an inline button -- the world's smallest, Nox claims -- that lets them answer or end calls and navigate tracks, along with a microphone.
