KOSS SB45 Headset with Elecraft K3

Bought this headset on Amazon for £20 after reading some mail on the Elecraft reflector. I wanted an electret mic so this meant either the SB45 or SB49. The only difference is that the SB45 doesn't have a volume control on the lead (which I think is a pest for radio use anyway).

The good:
The headset is very comfortable. So far 8hrs continuous in CQWW WPX and no issues. Fits over my big lugs comfortably and gives a reasonable amount of sound isolation.
Rx and tx audio are superb with the K3 (flat tx equaliser settings).
The headset can fold up into a very neat ball allowing easier packing for dxpeditions etc.

The bad:
The lead is very thin and I suspect has not much in the way of a screen, but so far no RF issues with a small ferrite placed half way along the lead (just in case).

The microphone stalk is very flimsy and not very adjustable, but it seems to sit in the right position.

Overall it's a great purchase and makes me a bit embarrassed at spending a comparative fortune on a Heil headset.
