NOTE 1: Some phones requires Bluetooth to be turned off for the EHS function to work

NOTE 2: Voice command with Sennheiser Electronic Hookswitch for Mobile Phone, may also depend on the phones Service Provider as well.

NOTE 3: Official iPhone adapters work MUCH better than the ones you can get on Amazon. If they are experiencing problems with remote answering or mic sound not going through headset, then that may be the cause. In fact, it is very likely to be the cause.
