Philippe’s (Solognac Product Manager) opinion of these earplugs
"I chose the CALIBER to offer a Bluetooth in-ear button-less and wireless model. All the functions and settings are made by pressing the product. Note that you will need some time to get to grips with the various functions. Also, take the time to choose the right size of plug to make sure that your ear canal is sealed and to maximise the level of protection. The case for charging and storage is a real bonus".
