Some of Audio-Technica's greatest innovations have gone into the MSR-7 and the 45mm True Motion Drivers boast a triad of notable improvements: lightweight voice coils, a custom-mounted printed circuit board, and a specially designed diaphragm that all work in harmony to improve transient response and minimize distortion.

If you hear an extended low and mid frequency response, the multi-layered air damping technology may be to thank. Three precisely placed vents in the lightweight aluminium/magnesium mix housings work to control air flow and improve dynamics while reducing unwanted resonance. Still not convinced? Tyll's crowned the MSR7 as Innerfidelity Wall of Fame worthy. For even more information, check out our interview with Audio-Technica on Head-Fi.
