At some point, someone produced an actually working TNG comm badge as a Bluetooth phone accessory, apparently it's still for sale: https://shop.startrek.com/products/star-trek-the-next-generation-bluetooth-communicator-badge-1 https://shop.startrek.com/products/star-trek-the-next-genera... Though from the reviews I've seen (and as with so many Bluetooth devices), it's unusably terrible, and the battery only lasts a few hours.
