Dark-spring premium linear named for its orange colorway. The R2 revision improves stem-to-housing tolerances; the polycarbonate top and nylon bottom pairing gives a balanced muted sound profile — not as deep as an all-nylon housing but noticeably less poppy than all-PC. A benchmark pick in the mid-weight premium linear segment.
