3.5 SENNHEISER 3.5mm TRS JACK (Grade-A) Code: 31503240

Sennheiser’s “3.5mm TRS mobile jack” typically refers to the specialized connection cables used to hook up their professional microphones (like the MKE 200 or MKE 400) or wireless receivers to smartphones and tablets.

Key Details:

• Cable Type:Sennheiser uses a coiled 3.5mm TRS-to-TRRS cable (commonly the CL 35 TRRS) to connect camera-style mics to a mobile device’s 3.5mm headphone jack.
• Microphone End (TRS):This is a 3-pole (Tip-Ring-Sleeve) connector that usually features a screw-lock mechanism. This screws directly into the microphone body so the cord can’t be accidentally yanked out.
• Mobile End (TRRS):The end that plugs into your phone or tablet is a 4-pole (Tip-Ring-Ring-Sleeve) This fourth pole is what allows the mobile device to receive the microphone’s audio signal while simultaneously allowing you to plug in headphones for playback.
• No Headphone Jack?Because modern phones often lack standard headphone ports, Sennheiser also produces the CL 35 USB-C cable, which replaces the TRRS end with a direct USB-C connection.
