Konig & Meyer 23860 microfoonarm incl. 6 meter XLR-kabel
The supplied cable is neatly worked away within the arm enclosure and although I personally would have liked a couple more meters, this can of course be easily extended with another microphone cable.
The main reason I bought a microphone arm was to make the most of limited studio space and the fact that the arm can be pushed aside or folded down when not in use is perfect for my needs.
There's really no downside I can think of to a well-made product like this - so long as it fits your needs - the K&M 23860 comes highly recommended.
