Review on Sennheiser CX 300S In-Ear Headphone with Smart Remote - Black (One-Button Control) by Kio Proviax ᠌

Dear "Sennheiser", in the era of telephones, do the following: *ear part (sounding) from Sennheiser CX 300-II * wire from Sennheiser CX 300S (silicone!) with asymmetry for the neck. * the presence of buttons: play / pause and two more buttons to rewind / select a track. *additional, removable "mechanism" for holding the "ear part" for running. Pros: *The only advantage: a thicker wire and the presence of a microphone. * Included branded chip - a convenient case. Its cons: * Symmetrical wire (do not hang around the neck). *Less than the first generation (CX300-II) in terms of volume, sound and ease of use.
