This is essential for connecting DPA headset mics. The build quality is impeccable as is everything with DPA. The belt clip comes unattached and there is no instruction to attach it (unscrew the black plastic cap and let the placeholder ring fall out then slide it in). Because the belt clip has tension it is a bit tricky to reattach the cap. I worried I might damage the exposed electronics. Once assembled it works like a charm. Tip: when screwing on the adaptor, turn the adaptor, not the cable.
