I have bought a pair of marley earphones. When I bought them I knew not all the buttons from the controller would be working. That is because the earphones are made for iOS so it uses CTIA. The Nexus 5 uses OMTP. The earphones have a three button controller, only the volume buttons aren't working (the mic and play/pause work). After some googling I found a lot of different CTIA to OMTP adapters/converters, but none could garanty that it would make the volume buttons work.
Has anybody ever bought such a converter and did it work with your android/Nexus 5? Are you now able to use the volume controls?
Thanks in advance!
