LEICKE Retro Handset Speaker Microphone Handset for smartphones and mobile phones - 3.5mm jack plug - gloss black (also available in pink and blue) (Wireless Phone Accessory)
Update 09/06/2015: Now I must say that after I talked to anyone about this handset, one has noticed or the opposite told me that this is the quality not so good and he quietly listen to me than usual. _________________________________________________
