Ready to go: the Sennheiser stereo earphones MX 70 with magnetic surfaces ensure a convenient handling during sports. These earphones are specially designed for sporty activities: using inbuilt magnets the earphones can be clipped together when hanging around the neck. That way they don’t dangle about too much when the user is moving. The casing is infolded with a very robust, sweat and water resistant, milky white TPE material. Powerful neodymium magnets ensure a high fidelity sound.
