I bought a pair in the late seventies/early eighties with the cheaper and smaller energiser unit and they were, as I recall, remarkably good. There were various permutations available from a budget energiser to a premium energiser and then a version that would drive more than one headset.
Thanks for that, I've read that the headphones were very good quality and were highly revered in the late 70s. From what I've scraped out of the internet so far PWB did a pair of headphones that were essentially Stax drive units with the transformer box itself made by, or certainly labelled as, PWB. This combination was priced at £33 in 1979 so by no means budget stuff, it also beat several other pairs of well established headphones in a review that I read (although the magazine title was not present on the clipping). Seems like PWB was on the right wavelength initially and then fell into the snake oil pit.
