Bringing a balanced attack across the entire range, the B3 emphasizes every aspect for a neutral yet lively presentation. When you throw in clear instrument separation, above-average isolation, and an extremely wide soundstage, every track shows remarkable improvement when broadcast through these babies. As the B3 only carries an impedance of 32 Ohms, it can be used with most mobile devices, but the power-hungry beast is fully unleashed when run through a headphone amplifier.
