The Sennheiser POP 1 (article 005232) is a protective black leather pouch with a belt clip for Sennheiser SKP plug-on transmitters, specifically the SKP 100 G-series, SKP 500 G-series and SKP 3000. A plug-on transmitter attaches to the XLR end of a dynamic or condenser microphone to make it wireless, and is often used by reporters, interviewers and camera crews. The POP 1 lets the transmitter be carried on a belt between takes or stored safely in a kit bag, protecting its housing and controls from knocks, scratches and dirt. Elastic sides give a snug fit and a touch-fastener flap closes the pouch, and retailers note a clear window so the transmitter's display remains visible. The pouch carries the Sennheiser logo, weighs 48 g and measures about 160 x 80 x 5 mm flat. It is a practical, inexpensive accessory for broadcast, ENG and event teams who move plug-on transmitters between microphones. The transmitter itself is not included, and Sennheiser covers the pouch with a two-year warranty.
