"Many thanks for the service of your excellent product of cordless
earphones which I safely received yesterday. I was using them when my
wife and I found TWO 3,000 year old bronze age hoards at Ludham in
Norfolk recently. We have found that they really concentrate your mind
when listening for those amplified signals, especially when detecting
alongside a busy and noisy road. The signals were sharp and very clear
and it was such a bonus not to be tied to our detectors whilst
searching and recovering a total of 59 Axe heads, Spear heads, Knives,
Gouges, Chisels and Tools etc. We can now go back out and search with
full confidence and perhaps find a third hoard, who knows?
