Where can I get a bluetooth headset in mauritius and in what price

On John Kennedy road in Port-Louis (where Air Mauritius building is located), there are a few people selling mobile phone and accessories there and you'll definitely get it there. You can also try the shops at the end of the same road, near Caudan entrance.

The price might depend on the make of the phone.

At game trianon! ive saw one recently there but i dont remember the price! you can also check task, compuspeed, jacey or pascal computer.
