I'm just prep'ing a few Beyerdynamic DT250 headsets for a customer - football club we work with a lot! Their commentary guys love these headsets and the quality/comfort is hard to beat for either pitch-side or commentary booth use. They come with a proprietary connector and being German it's all beautifully manufactured.
This customer sometimes uses these with portable Glensound ISDN codecs (reporter-type mobile packs) and sometimes with Yamaha audio mixers and so they need both the 5-pin XLR option and the 3-pin XLR/1/4" stereo jack cable. Since removing the rigged cable requires a screwdriver and is fiddly I normally ship these with the 5-pin cable and make up a breakout;
Alternatively you can order the two different cable options, if you can get your colleagues in Sales to pay attention!
