DPA does not offer one. Can you solder? If so, or if you have someone that can do so for you, its pretty easy to make your own. Otherwise you might find something on Ebay.
To make your own, this is the easiest route-
1) Order a short microdot interconnect cable with female microdots (10-32 size) installed on both ends.
2) Order a stereo-mini TRS plug (1/8" / 3.5mm), either straight or right-angled.
3) Cut the female microdot terminated interconnect cable in half, strip back the wire jackets and prepare both wires for soldering.
4) Solder the two wires to the stereo-mini plug (Left center conductor to Tip, Right center conductor to Ring, both shields to Sleeve).
You can source 10-32 microdot terminated interconnect cables from CDINT.com (as well as other places). Here is a link to a 1 foot cable with female 10.32 microdots on both ends-

However, the center conductor in permanently attached DPA microphone cable is super tiny, and its a real PITA to solder without burning it up or breaking it. These cables from CDINT have a thicker, much easier to solder center conductor.
CDINT may offer Lemo terminations that could be directly attached to the existing Lemo terminations on the micrphones you have. If so you will need to contact them to make sure they can be wired with the same pin assignment as the Lemos on the micrphones.
