Plantronics and Sonim have announced a team-up to bundle together the Plantronics Explorer 370 Bluetooth headset and Sonim Xtreme Performance 1 handset for people who "work and play in extreme environments".

The Plantronics Explorer 370 has a ruggedised design and is durability tested to meet military-grade specifications.

It's water, dust and shock resistant, and features windscreen technology to ensure users experience clear calls no matter what the environment.

Matching that toughness, the Sonim XP1 is engineered for extreme outdoor conditions and can withstand water, dust, salt, fog, and humidity, drops on concrete and can operate at extreme temperatures.

The new Plantronics Explorer 370 Bluetooth/Sonim XP1 Bundle will be priced from 299 euros and is available now at major retailers.
