Product Research


Single Dynamic Driver: The Mackie MP-series professional in-ear monitors are made for live, on-stage performances. The monitors feature molded low-profile enclosures for maximum comfort and bass response. The MP-120 is equipped with a single, high-performance dynamic driver that offers a good balance of bass, high-frequency detail, and clear vocals. The earphones come with three styles of ear tips in three different sizes, so you can choose what works and fits best in your ears. The MP-120s include a hard molded plastic case to hold your in-ear monitors and ear tips.

Cable: The MP-120 comes with a 59.1" shielded, braided cable that delivers extra durability and sonic performance. It features an over-ear design to keep them securely in your ears, and the cable behind your head and out of the way. The cable is removable and replaceable in case of damage. The cable attaches to the ear buds via a swiveling MMCX connector. The cable is terminated into a right-angled 3.5mm plug.

Accessory Plug: The MP-120 in-ear monitors are designed for use on stage, or for leisure. They include a 3.5mm-to-1/4" adapter so you can use your headphones with your home audio components or professional sound consoles with a 1/4" headphone jack.

Ear Tips: The MP-120 comes with a wide variety of ear tips. The sound isolating tips block ambient noise (up to about 40dB), while ensuring a comfortable and customized fit. A good seal is required for optimal sound isolation and bass response, and maximum comfort for extended wear. The ear tips come in small, medium, and large sizes, in the following styles:

  • Silicone: The silicone rubber ear tips are soft and flexible.
  • Foam Ear Tips: The soft foam ear tips compress and expand to form a tight seal in your ear canal.
  • Double-Flange Ear Tips: The Double-Flange tips are made of soft, silicone rubber with dual flanges of increasing diameter to fit the shape of your ear canal.

Carrying Case: The MP-120s come with a compact, molded, hard plastic carrying case that will protect your in-ear monitors when not in use. This clam-shell style case has a locking closure and a carabiner-style clip for attaching it to other items.


  • Frequency Response: 20Hz - 20kHz
  • Sensitivity (1 kHz): 102 dB SPL/mW
  • Impedance: 32 ohms
