These Sennheisers are an open, neck-band design like the Grado iGrado headphones, and they leak just as much sound, but they also perform admirably.
They are a little less attacking and transparent than the iGrados, but weightier, and still with a spacious, detailed delivery.
An excellent, easy-listening alternative to the Grados.
