Anyone who wants to use your own headphones, which should still buy this set here and not only the AD-44, which is also available as bulk. They might experience bad surprises, because with the bulk version often the buttons are not working (see also my review for bulk version).
Note: AD-44 is not always equal to AD-44! Here, the additional cost to set definitely worth it!
PS: tested was equipped with a Nokia E51, 6290 and 6220 classic.
