If you want a wired in-ear monitor that disappears into your ears, isolates up to 40 dB of stage noise and keeps a mix clear enough to sing against, choose Mackie MP Series In-Ear; if you need over-ear studio headphones that fold up, swivel for one-ear cueing and translate reliably across mixing, DJing and travel, choose Audio-Technica ATH-M50x.
• Mackie MP Series In-Ear — biggest strength: up to 40 dB of sound isolation and a precision-tuned single balanced-armature driver (20 Hz–20 kHz) built specifically for hearing yourself clearly on stage.
• Mackie MP Series In-Ear — biggest trade-off: it's an in-ear design, so it seals inside the ear canal, and the set is wired-only with no over-ear comfort option for long desk sessions.
• Audio-Technica ATH-M50x — biggest strength: big 45 mm dynamic drivers with neodymium magnets and CCAW voice coils, a wide 15 Hz–28 kHz range, and a foldable, swiveling over-ear frame that handles studio and mobile work.
• Audio-Technica ATH-M50x — biggest trade-off: over-ear closed-back cups isolate passively and reduce bleed, but they can't match the deep in-ear seal of a properly fitted monitor, and the frame is bulkier to carry than a pocket-sized IEM case.
• Who each pick is for: Mackie MP Series for performers, vocalists and anyone who needs maximum isolation and a discreet fit; ATH-M50x for producers, mixers, DJs and listeners who want one durable pair for the desk, the booth and the road.
The Mackie MP Series is built around one job: letting you hear your own voice and your mix while everything around you gets pushed down. The headline figure is up to 40 dB of sound isolation, which comes from the ergonomically molded low-profile enclosure plus the ear tips — and Mackie throws in four different tip types in three sizes each (silicone, wide-bore silicone, memory foam and triple flange). That's not a marketing extra; it's the whole point. A good seal is what gives you both the isolation and the bass response, so having four families of tips means most people can actually find that seal.
The audio side is a single balanced-armature driver covering 20 Hz to 20 kHz with 94 dB sensitivity. Balanced armature drivers are known for detail and vocal clarity rather than a huge, loose low end, and Mackie tunes this one for what it calls the balance of vocal clarity and ample low-end for stage performance. In practice that means your own voice sits forward in the mix instead of getting buried. The cable is internally braided with outer shielding and terminates in MMCX connectors, so you get two cables in the box — a clear one without a controller and a black one with a controller — and you can swap them if one ever fails. That's a genuinely practical durability decision for gear that lives in a gig bag.
Who should skip it: if you mix for hours at a desk and hate things inside your ears, or you want one pair to also serve as your casual over-ear headphones for gaming and long listening sessions, this isn't the tool. It's also worth noting the set is wired, with a 3.5 mm jack and a 1/4-inch adapter included — there's no wireless mode, and the panel lists Bluetooth only as a listed technology field, not as a feature you should count on.
Audio-Technica ATH-M50x: Who It's For
The ATH-M50x ENSO is the opposite philosophy: a closed-back over-ear monitor you wear around your whole ear, not inside it. The core of it is a 45 mm dynamic driver with neodymium magnets and CCAW voice coils, covering 15 Hz to 28 kHz. That's a wider stated range than the Mackie's 20 Hz–20 kHz, and the dynamic driver design is what gives it the controlled low end and detailed mids that make it useful for tracking, mixing and cueing. The tuning goal is translation — hearing balance and separation so your decisions hold up elsewhere.
The physical design is where it earns its keep for working engineers. The circumaural cups contour around the ears, which cuts outside noise and limits bleed into a live mic — important when you're tracking vocals or a loud amp in the same room. The earcups swivel, so you can slip one ear off for single-ear monitoring, which is exactly what DJs and vocalists doing cue work need. And the whole thing folds, so it packs down for mobile setups and travel. The headband is reinforced and the ear pads are cushioned for long sessions, and the enclosure mixes softer materials at the pads with durable material on the shell and headband.
The ENSO bundle is generous on accessories: a headphone stand, a carry case, a cleaner, a 15-foot balanced 1/4-inch TRS interconnect, touch-fastener straps and a microfiber cloth. The headphones themselves use a 3.5 mm connection with a screw-on 1/4-inch adapter and include three detachable single-sided cables, so you can run them from a laptop, an interface or a portable player without hunting for the right lead.
Who should buy it: producers, mixers, podcasters, DJs, gamers and anyone who wants one sturdy pair of over-ears that covers studio work, editing and everyday listening. If you do a lot of one-ear cueing or you travel with your gear, the swivel-and-fold design is a real advantage.
Who should skip it: if your priority is absolute isolation on a loud stage, or you want something that vanishes in a pocket, the bulk and the passive seal of an over-ear won't get you all the way there. And if you specifically need an in-ear monitor for performing, this isn't that product.
• Best isolation → Mackie MP Series In-Ear. Up to 40 dB with a proper tip seal is in a different league from passive over-ear cups.
• Best for stage and live performance → Mackie MP Series In-Ear. Vocal clarity from a balanced-armature driver plus a low-profile, all-night-comfortable fit.
• Best for mixing, tracking and critical listening → Audio-Technica ATH-M50x. 45 mm dynamic drivers and a 15 Hz–28 kHz range built for hearing balance and separation.
• Best for DJs and one-ear cueing → Audio-Technica ATH-M50x. Swiveling earcups make single-ear monitoring straightforward.
• Best for travel and portability → split decision. The ATH-M50x folds and comes with a case and stand; the Mackie packs into a molded hard case that's smaller than a fist.
• Best fit flexibility → Mackie MP Series In-Ear. Four tip types in three sizes each (silicone, wide-bore, memory foam, triple flange) is unusual and makes getting a seal far more likely.
• Best accessory kit out of the box → Audio-Technica ATH-M50x. Stand, case, cleaner, 15-foot TRS cable, straps and cloth cover desk-to-road setups.
• Best for long desk sessions → Audio-Technica ATH-M50x. Cushioned over-ear pads and a reinforced headband are made for extended wear.
If I had to pick one, I'd take the Audio-Technica ATH-M50x — in my opinion it's the more versatile of the two, because a foldable, swiveling over-ear with 45 mm dynamic drivers and a full accessory kit can cover mixing, tracking, editing and casual listening from one pair. That said, I'd recommend the Mackie MP Series In-Ear without hesitation to anyone who performs. If your problem is hearing yourself over a loud stage or a noisy room, no over-ear is going to solve it the way a sealed in-ear with up to 40 dB of isolation will. Buy for the job you actually do, not the spec sheet you like reading.
FAQ
Yes. The Mackie is rated for up to 40 dB of sound isolation through its in-ear seal and tip selection. The ATH-M50x reduces noise passively with closed-back over-ear cups, which is useful but not the same level of blocking. For loud stages or noisy commutes, the in-ear wins.
You can, especially for DJ and one-ear cueing work thanks to the swiveling earcups and low bleed. But for a vocalist or drummer who needs to hear a mix over a loud band, the Mackie's in-ear isolation is the more practical choice.
It depends on your preference. The ATH-M50x is designed for extended wear with cushioned over-ear pads and a reinforced headband. The Mackie is built to be worn all night too, but its comfort comes from a low-profile in-ear fit and the right tip — some people never get used to anything inside the ear canal.
In my opinion, the ATH-M50x is the better all-rounder for studio, home and travel use. If performing is your main job, get the Mackie MP Series instead. Either way, check the current price on Amazon before you commit, since both are sold in different configurations and bundles.
