The Stethophon 04 from Sewerin is a comprehensive, compact leak detector equipped with a built-in contact microphone that delivers clear sound reproduction, even when the noise is barely audible. The Stethophon 04 can be used with wired headphones or Sewerin SDR wireless headphones. When using Sewerin SDR headphones, the device will automatically connect to the headphones once the receiver and headphones are powered on. Sewerin SDR wireless digital signal processing technology prevents audio interference, such as hissing or re-amplification. Each Stethophon 04 includes a user-selectable audible filter function, allowing users to focus on the leak noise frequency while filtering out unwanted noise.
