Solid cable with chunky connectors (one of the ends rattled a little when it arrived, but as the connector screws together, tightening it up by hand stopped the rattle - it had obviously worked a little loose in transit).
The cable is exactly as described - relatively short, but providing a step down in size from 6.35mm headphone connector to 3.5mm headphone connector. I use this with a set of full sized Sennheisers connected to a variety of devices (laptop, Zune, TV...) - the connector is less awkward than using a conventional 6.35mm - 3.5mm adaptor (particularly on small devices like the Zune or an iPod).
