I've had a PM from him Saturday saying
"apologies for the lack of response to the pm's I've been away with work and only got back yesterday. I posted the headsets about 10 days ago, sadly the monkey in work put about 30p postage on them and they landed back on my desk. Reposted this morning, hope I haven't ruined any retro rides in the last week or so.
Hope it reaches you safe and sound at the start of the week "
