Speakerphone is a new feature introduced with the Zipp and Zipp Mini. It allows the device to act as a speaker and a microphone during a phone call. This eliminates the need for having to hold your phone to your ear, while also allowing others to participate in the conversation (such as during a conference call).
When a phone connected to the speaker via Bluetooth gets an incoming call, simply tap the Nightingale to answer, and the speaker's built-in microphone will automatically activate. It is important to answer the call using the Nightingale, as it will not be picked up by the speaker when answered on the phone.
If you are listening to music when receiving a phone call, playback is paused until the call has ended.
