The Zowie EC1-C brought the large EC1 shape into the lightweight era at 80 grams wired with the PAW3370 sensor and a paracord-style cable. The 15-gram weight reduction from the EC1-B was dramatic for a large mouse, making the EC1-C feel like a different product despite maintaining identical external dimensions. The flexible cable eliminated the cable drag that had been the EC1's biggest practical disadvantage. For large-hand players who had always loved the EC1 shape but envied the lighter mice their teammates used, the EC1-C was a revelation. It proved that even Zowie's largest shape could benefit meaningfully from modern weight engineering.
