Mackie MP-120 BTA Single-Driver In-Ear Monitors with Bluetooth MMCX Cable

Mackie MP-120 BTA: One In-Ear Monitor, Wired for the Stage or Wireless for the Street

The Mackie MP-120 BTA pairs the single dynamic-driver MP-120 professional in-ear monitor with the MP-BTA Bluetooth 5.0 adapter cable, so one set of monitors does double duty. Plug in the wired braided cable for a rock-solid stage connection, or clip on the Bluetooth neckband cable to go wireless for the commute, the gym, or a phone call. With up to 40 dB of isolation and a punchy, articulate dynamic driver, the MP-120 BTA is the in-ear monitor that follows you from the stage to the rest of your day.

The Same Trusted MP-120 Monitor at the Core

At the heart of the bundle is the MP-120 itself: a single high-performance dynamic driver in each earpiece, tuned across a full 20 Hz to 20 kHz range with a 32-ohm impedance and 93 dB sensitivity. That focused single-driver design delivers deep, physical bass without clouding the vocals and lead instruments in the midrange. The molded low-profile shell seals your ears for up to 40 dB of passive isolation, keeping stage roar and street noise out whether you are running wired or wireless.

Go Wireless With the MP-BTA Bluetooth Cable

The MP-BTA adapter is a Bluetooth 5.0 neckband cable that clips onto the MP-120 earpieces in place of the wired cable. Bluetooth 5.0 gives it a stable connection with strong range, and an inline microphone with playback and call controls means you can answer calls, pause a track, or change songs without reaching for your phone. It transforms the MP-120 from a stage-only monitor into everyday wireless earphones that still carry the isolation and tuning of a real in-ear monitor.

Two Cables, One MMCX Standard

Both the wired braided cable and the MP-BTA Bluetooth cable connect through the same swiveling MMCX connectors, so switching between them takes seconds. Use the wired cable into a bodypack, headphone amp, or mixer for the lowest-latency, most reliable monitoring on stage - a gold-plated 1/8-inch to 1/4-inch adapter is included - then swap to the Bluetooth cable when you want to cut the cord. Because the connection is MMCX, a damaged cable is a quick, low-cost replacement rather than a dead pair of monitors.

Fit, Isolation, and Protection in the Box

The MP-120 BTA includes foam, silicone, and double-flange ear tips in small, medium, and large so you can dial in the seal that gives you the best isolation and comfort. A hard carrying case keeps the monitors and both cables organized and protected between uses. Getting the right tip is what unlocks the full 40 dB of isolation, so it is worth trying each material to find your best fit.

Who the MP-120 BTA Is For

Musicians and performers who want a single in-ear monitor that works wired on stage and wireless everywhere else reach for the MP-120 BTA. It suits the gigging player who also wants Bluetooth earphones for the commute, the worship or rehearsal musician who values a flexible connection, and the content creator who needs isolating monitors plus hands-free calls. If you want one set of in-ears for both the show and the rest of your life, the MP-120 BTA delivers both in a single package.
