Audiolab M-EAR 4D
The M-EAR 4D is a three-way design sporting four drive units – one for high frequencies, another for midrange and two for bass.
Both M-EAR models incorporate balanced armature drivers, which differ from the dynamic drivers found in most headphones and earphones. These drivers use an electronic signal to vibrate a tiny reed suspended between two magnets; this movement is transferred to an aluminium diaphragm that generates soundwaves. Balanced armature drivers deliver greater efficiency and are extremely compact, enabling several drivers to be combined in small, sound-isolating in-ear monitors.
Manufacturers Details:
The result, in the case of the M-EAR 2D, is a pair of discrete IEMs (In Ear Monitors) delivering taut, punchy bass, captivating midrange clarity and crisp, clean high-frequency detail, with no harmonic interference. Invest in the M-EAR 4D and the sonic return is even greater space, scale and dynamic expression.
