Mackie MP-320 Triple Dynamic Driver Professional In-Ear Monitors
The MP-320 sits in the middle of the Mackie MP series and is the model that moves to three dynamic drivers. Splitting the frequency range across three drivers with a precision 3-way crossover lets the low driver do the bass work while the others stay clear, which is why these keep the punch that all-dynamic designs are known for.
- Triple dynamic drivers: clarity in the mids and highs with punchy, accurate bass.
- Precision 3-way crossover for balanced sound across the whole frequency range.
- Frequency response: 20 Hz to 20 kHz.
- Impedance: 15.5 ohms, plus or minus 15%.
- Sensitivity: 100dB, plus or minus 3dB at 1mW at 1kHz.
- Up to 40db of sound isolation from the ergonomically molded low-profile enclosure.
- Clear enclosure for a streamlined look on stage.
- Detachable MMCX cable: shielded and braided, with a connector that swivels, and an over ear fit that keeps the cable behind your head.
- Four ear tip types in small, medium and large: foam, silicone, wide-bore silicone and triple flange.
The Mackie MP-320 is a professional in-ear monitor built around three dynamic drivers. The step up from the two-driver MP-220 is not just more output, it is a precision 3-way crossover that separates the frequency spectrum further while keeping every driver a dynamic type, so the bass stays physical rather than polite.
How the three drivers work together
Splitting the range three ways means each driver covers less ground. The result is exceptional clarity in the mid and high frequencies with punchy, accurate low end underneath, and mix translation good enough to trust on stage. Quoted frequency response is 20 Hz to 20 kHz, impedance is 15.5 ohms plus or minus 15%, and sensitivity is 100dB plus or minus 3dB at 1mW at 1kHz.
Fit and isolation
The enclosure is ergonomically molded and low profile, which is what delivers up to 40db of sound isolation as well as comfort across a long set. The shell is clear for a streamlined onstage look. Four types of ear tip are included, foam, silicone, wide-bore silicone and triple flange, each in small, medium and large, so the seal is something you dial in rather than accept.
Cable and connectors
- Shielded, braided cable built for durability and sonic performance.
- Detachable MMCX connector that swivels, for comfort and long-term reliability.
- Over ear design that keeps the earpieces secure and the cable behind your head.
- A second cable with an in-line remote is included for everyday listening.
In the box
The MP-320 ships with a hard molded case, a gold-plated 1/8 inch to 1/4 inch adapter, the additional cable with in-line remote, the full set of ear tips and a cleaning cloth.
