Discreet Clip-On Wearing

A small mic on a collar keeps the subject talking instead of watching the gear.

Coverage for Two Speakers

A question and an answer both need to land, not only the voice nearest the mic.

Speech Clarity in Noise

Traffic and cafe clatter sit in the same room as the only take you will get.

Onboard Backup Recording

A dropout in a one-time conversation cannot be fixed by asking again later.

Useful Wireless Range

Subjects walk while they talk, especially on a tour of their own workplace.
