adidas and Monster join forces again to unleash the adidas Sport by Monster in-ear headphones for athletes. The first models to hit the street are the adidas Sport Response™ by Monster and adidas Sport Supernova™ by Monster. Both models make their international debuts at the London and Boston Marathons at the end of April 2015.

The Supernova model offers total noise isolation, while the Response model has a non-isolating design that enables users to hear outside sound during activities such as running on roads or through urban environments.

Each model features Monster’s patented SportClip™ for a comfortable non-slip fit, as well as a 100% sweat-proof design with anti-microbial eartips. Calls can be taken with ControlTalk™ on-cable mics for hands-free control.

The adidas Sport Response by Monster and adidas Sport Supernova by Monster in-ear headphones will be available from May.

• adidas Sport Response by Monster: £39.95
• adidas Sport Response by Monster (with ControlTalk): £59.95
