5. Does the KA2 support in-line control and answering phone calls?

1. There is no physical button on the KA2, so in-line control will not be supported.
2. Since different smartphones vary in USB phone call permissions, the in-line control and phone call functions of the KA2 are temporally unavailable.
3. An incoming call will be passed out through the speaker and microphone of the mobile phone. So you can pick up the phone to answer the call without unplugging the KA2.
