UE Buffer Jack - Inline Attenuator / Impedance Buffer (3.5 mm)

An inline male-to-female 3.5 mm adapter that attenuates the audio signal and buffers impedance between the source and sensitive in-ear monitors.

Designed to lower overly hot/noisy outputs -notably airline in-flight entertainment - and to reduce issues from source/earphone impedance mismatch (e.g., hiss and touchy low-volume control). Plug-and-play; no power required.
