The Sennheiser EW receiver unit requires a locking connector for proper operation. This cable is not compatible. Kopul does offer a cable the ROC-LM2. Sennheiser also offers an XLR cable identical to the one that ships with the system, the CL-100

Yes you can!

The Kopul Stereo Right-Angle 1/8" Male Mini-Jack to XLR Male Cable (1.5'), B&H # KORSMXM015, is a relatively short cable. If the cable is very short compared to the wavelength, the phase shift between the two reflections will be very small and will cancel. It merges both channels of the stereo output from your playback device into a mono signal for connection to an XLR input. Phase cancellation should not be an issue. The 24-gauge OFC conductor, copper spiral shielding, and PE insulation result in a quiet cable with improved conductivity, assuring pure transfer of audio signals.

The Kopul Stereo Right-Angle 1/8" Male Mini-Jack to XLR Male Cable is an unbalanced cable.

This cable is not meant to be used with the Sony UWP/ URX receiver. Here's the direct Sony replacement output cable for that receiver B&H # SOEC0.46BX.

No, the Kopul Stereo Right-Angle 1/8" Male Mini-Jack to XLR Male Cable is not compatible for use with the Deity Microphones V-Mic D3 Pro Shotgun Microphone. The V-Mic D3 Pro requires plug-in power to function, so you will need to use an XLR adapter with a phantom power converter like the Deity Microphones D-XLR 3.5mm to XLR Adapter with Phantom to Plug-In Power Conversion (B&H # DEDXLR), which is the adapter that Deity includes with their location recording bundle for connection to an XLR input, and connect to a device that will supply phantom power. The D-XLR adapter will allow you to use the original 3.5mm TRRS smart cable that comes included with the microphone to convert the plug and enable compatibility for connection to the XLR input on the Focusrite Scarlett Solo USB Audio Interface. You will need to have the phantom power (48V) switch for the XLR input on the interface turned on in order to supply power the mic. If you need a longer cable, simply attach a standard XLR to XLR cable between the XLR input on the interface and the XLR output on the Deity D-XLR adapter. For example, you can use the Kopul Premium Performance 3000 Series Neutrik XLR Male to XLR Female Microphone Cable - 10' (B&H # KOM3010) or similar cable in any length you prefer for your extension.
