Back in September, Paradigm announced that they were branching out to handy audio under the Paradigm SHIFT brand. In the same announcement, they promised that the E1 , E2m and E3m earbuds would be coming lickety-split. The company says that all three models are starting to ship, and have detailed specs and prices for each by-product.
The E1 is the entry-level model, at $49.99 each. Critically tuned to Paradigm's Keep track of Series 7 speakers, the E1 features 8mm super-neodymium drivers, a sensitivity rating of 103 dB, and a rated frequency effect of 10 Hz - 18 kHz.
For $99.99, the E2m bumps the sensitivity rating up to 104 dB and the frequency feedback to 10 Hz - 19 kHz. Another difference is that the E2m is critically tuned to Paradigm's high-end Specification Studio speakers, and features a two-piece sealed construction.
The last in the earbud lineup is the E3m. For $129.99, this example is crafted from one-piece CNC precision-machined aluminum and has a sensitivity rating of 105 dB and a rated frequency retort of 8 Hz - 19 kHz. Like the other models, the E3m is critically tuned to one of Paradigm's current keynoter products. In this case, it's the high-end Reference Signature speakers.
