Our Verdict Open, balanced and controlled - these cans deliver the goods For Controlled, well-balanced sound plenty of bass-weight Against A tad anti-social if you commute Reviewed on 3rd December 2009 The MM 60s look like Sennheiser's PX 100s with a mic/control unit attached. That's how they sound, too: open, balanced, controlled and detailed, with plenty of bass weight and depth. They're open-backed, so a little anti-social on the train or bus, but if that's not how you commute, their all-round listenability makes them an easy recommendation. The presence of Grado's iGrados means the PX 100s are rated at four stars, but Grado doesn't make 'phones with built-in mics, so we're happy to award the MM 60s the full five.
