Still need some persuasion to cop a pair of in-ears this summer? In the immortal words of 50 Cent: "It's hot out this bitch, that's a good enough reason." And the Street in-ears surprisingly bring the audio heat with its 11mm drivers producing punchy bass and solid highs/mids performance. As a bonus, SMS bundles an airplane two-pronged converter for frequent flyers to sonically zone out above the clouds.
