UNOBTAINIUM:  The Legacy Collection.

It has been our pleasure to offer some truly interesting items over the years. As is the case with this listing from 2016.

The Brüel & Kjaer, Type 4128C Head and Torso Simulator simulates the acoustic properties of a human head and torso by using a manikin with built-in ear and mouth simulators. A lot of things can be tested, like telephone handsets, headsets, audio conference devices, microphones, headphones, hearing aids, and hearing protectors.

There's a new store category for tech surplus like this that have graced our store's shelves and now live on in memory.

Check out our new category: UNOBTAINIUM: The Legacy Collection

Item was as described, and very fast delivery!

5 stars across the board for every seller rating category, and I would buy from this seller again. And per my request, the capacitors were also very well packed for safe delivery.

Obtainium have been a very helpful seller to me.

In recent times I have had a few items go astray enroute to my address in Australia. This seller was most helpful & encouraging, regarding the onward tracking & eventual safe delivery of this item. This item's arrival in good condition was a joy to me as, it was a rare part that fitted my military comms. Well done seller. I would gladly recommend this seller to all potential buyers.
