Designed in collaboration with touring musicians, the M6 PRO is an all-in-one in-ear earphone for stage, gym, and street. A new driver with an ultrathin 5µm diaphragm and aluminum voice coil is capable of more precise movement, delivering engaging, dynamic audio with better balance compared to the original M6 earphones. The resulting sound combines deep, yet well-balanced bass, good clarity, and crisp detail reproduction. So buy this MEElectronics M6 PRO Universal-Fit Noise-Isolating Musician’s In-Ear Monitors with Detachable Cables - £38.00.
