For two months, Jamie-Lee Lewis has barely been able to wipe the smile off her face.

Her $25,000 Cochlear implant, which hears for her in all other aspects of her everyday life, could not go the one place she loves being the most - in the pool.
So she swam in silence. Played water polo in silence. Spent childhood summers in the pool playing with others in silence. Went to the beach in silence.
But no more.
More than 20 years after it pioneered the revolutionary hearing device, Cochlear, the manufacturer of the implant, has developed a waterproof silicone sleeve to protect it in the water, the Aqua+, which only became available in Australia in September.
