As a sound device it is recommended to use:
Headset - in case you cook yourself
Any headset is suitable, but we recommend using a wireless one (there will be more freedom in movement)
Portable column - if you cook in several hands (two people)
If the speaker is without a microphone, your sound will go through the microphone of the phone or tablet, take this into account when placing the devices.
We advise you to take into account the total time of the event (about 3.5 hours) and recommend that you charge all your devices (speaker, headset, tablet / mobile phone) to the maximum, and also be able to connect to chargers.
We urge you not to use the speakerphone, this can also add an echo to the air!
