Featuring a single titanium coated armature driver, up to 16dB of noise isolation, and three sizes of silicon tips, the 220 will be available in February for $80. A vi model with in-line microphone will sell for $10 more. An cheaper model without the titanium coated driver, the MetroFi 170, was released at the same time for $50.
