Before was a waterproof headphones manufactured by SONY. Now is introducing the waterproof phone - Sony's Xperia Z handset.
Sony says the handset, which has a 5inch (12.7cm) screen, is capable of being submerged in water of up to one metre (3.3 ft) in depth for 30 minutes.
The trade-off is that handset's various ports, including the one for its headphones, all feature protective plastic covers that must be unclipped before they can be accessed. The handset also has an NFC chip allowing owners to play back video on their TV simply by tapping the phone against it. This chip could also be used as a credit card in the future.
Kuni Suzuki, President and CEO, at Sony Mobile Communications said:
"With great specifications, Sony’s media applications, One-touch functions and outstanding battery life, Xperia Z is well positioned for leadership in the smartphone market".
'But we don't know what this device is going to be competing with this year.'
It’s probably the company’s best phone yet.
