Translation ear buds

On recent C5 trip I travelled via Morocco and despite speaking a bit of Arabic thought it might be interesting to try a pair of the new translation earbuds as I had a long stop over. The ones I used get your own ones here

They also have nmber of other functions, the most useful as flying was noise cancellation but they act as mormal blue tooth ear buds too. The ones that I was recommended to try were these but they were not available when I looked.
