The duals seem to be the same, but the triples are indeed very different from the LiveWires Trips. The Trips use the same setup as the Westone ES3X: Knowles Acoustics CI22955 for bass, and the Knowles TWFK dual driver for mids and highs. The Fidelity triples appear to be configured with 2 large drivers and one small driver. Here is a link with that info, unfortunately I can't find any follow up from any of the people who had sent theirs back.
Doesn't the SE530 also use dual lows + a tweeter? I wonder if the Fidelity Triples use similar drivers.
