If you’re sick of trying to choose among dozens of lookalike IEMs in the racks at electronics stores, you’ll find the C5 to be welcome relief. This IEM resembles nothing else on the market. The back of each titanium earpiece holds B&W’s Micro Porous Filter, a layer of hundreds of tiny steel balls that the company says works as a sonic diffuser.

Paradigm tunes its IEMs to match the sound of its different speaker lines. The E3m is the top-of-the-line model, thus it is said to match the company’s top-of-the-line Signature Series speakers. The midpriced E2m matches Paradigm’s Studio Series speakers, and the low-priced E1 matches the Monitor Series 7 speakers.

The first headphone to which Barton brings his ultra-scientific approach is the M4U 2, a noise-canceling model poised to go up against the likes of the Bose QC15.
