If you want sound-isolating in-ear monitors for a call center, choose Mackie MP Series In-Ear; if you need open-back headphones for spacious, detailed listening, choose Audio-Technica ATH-R50x. For the call-center use case, I’d pick Mackie because its in-ear design and sound isolation make more sense when you want to keep outside noise down. The ATH-R50x is the more natural fit for quiet-room listening and audio work.
• Mackie MP Series In-Ear: In-ear fit, included range of ear tips, and up to 40 dB of sound isolation; the trade-off is a cable and a fit that depends on choosing tips that suit your ears.
• Audio-Technica ATH-R50x: Open-back listening, 45 mm drivers, and two detachable cables; the trade-off is that its open design offers no noise control.
• Mackie is for: People who want an isolating in-ear option for a noisy work area or performance use.
• Audio-Technica is for: Listeners who value open-back sound and comfort in a quieter space.
• For a call center: Mackie is the more practical of these two designs, though neither product’s listed features establish a dedicated call microphone.
The Mackie MP Series In-Ear is built around a low-profile in-ear design, replaceable ear tips, and sound isolation of up to 40 dB. That combination makes it the more plausible choice of the two for a busy shared environment. If nearby conversation or office activity is part of your workday, isolating some outside sound may help you focus on what you’re listening to.
The included tips give you several ways to adjust the fit: the package information lists silicone, wide-bore silicone, memory foam, and triple-flange tips, each in three sizes. There is also a hard carrying case, a cleaning tool and cloth, and a 1/4-inch adapter. Those are useful details if you need to pack the earphones away between shifts or connect them to compatible audio equipment.

The Audio-Technica ATH-R50x is an open-back, over-ear headphone with 45 mm dynamic drivers and a stated frequency response of 5 Hz to 40,000 Hz. Its open construction is designed to give sound a more spacious, natural presentation. That makes it the stronger fit for focused listening, audio editing, or working with recordings in a quiet room—not for shutting out a busy office.
Its 50-ohm impedance is intended to work with common sources such as laptops, mobile devices, and standard audio interfaces without requiring a dedicated high-power amplifier. The listed package includes two detachable, single-sided locking cables: one 3.0 m and one 1.2 m, with 3.5 mm plugs and 1/4-inch adapters. That gives you a choice between a longer cable for a desk setup and a shorter one when you want less slack.
The key trade-off is right in the design: the ATH-R50x has no noise control. Sound can pass through an open-back headphone, so nearby office noise remains part of your environment, and people around you may hear some of what you play. I would not choose it as the best in-ear earbuds for call center because it is neither an in-ear model nor an isolating one. It may suit someone who works in a quiet space and wants an open-back listening tool, but the listed specifications do not identify a call microphone.
Side-by-Side: Which Should You Choose?
• Best for sound isolation → Mackie MP Series In-Ear. It is listed with up to 40 dB of isolation; the ATH-R50x has no noise control.
• Best for choosing among ear-tip styles → Mackie MP Series In-Ear. The included tip options cover several materials and designs, in three sizes.
• Best for flexible cable length → Audio-Technica ATH-R50x. It includes detachable 3.0 m and 1.2 m cables.
• Best for packing into a small kit → Mackie MP Series In-Ear. Its included hard case is made for carrying the in-ears and accessories together.
• Best for a quiet audio-editing space → Audio-Technica ATH-R50x. Its open-back design and stated wide frequency response suit listeners who want an open reference-style headphone.
• Best for call-center focus in a noisy area → Mackie MP Series In-Ear. Isolation is the more relevant feature, but neither model’s listed details specify a built-in call microphone.
• Best multipoint clip-on earbuds for call center → Neither. The Mackie is wired, and the Audio-Technica is a wired over-ear headphone; neither is listed as a clip-on or multipoint wireless product.
I’d choose the Mackie MP Series In-Ear for a call center because its in-ear fit and stated sound isolation are more useful in a noisy work area than an open-back design. The variety of included tips also gives you options for adjusting the fit.
That recommendation has a caveat: I would confirm that your call setup has a separate microphone or otherwise supports the Mackie. If you need a headphone with a microphone, the listed information doesn’t establish that either model provides one. For quiet listening and an open presentation, I’d choose the ATH-R50x instead.
FAQ
No noise-control feature is listed for the ATH-R50x. Its open-back design is intended to let air pass through the earcups, so it is a poor match if blocking nearby office sound is a priority.
The listed connection is wired, with a 3.5 mm jack. Although some product-information fields mention Bluetooth, the style and connectivity details identify this model as wired, not as a true wireless or multipoint earbud.
Value depends on the current price and what your setup needs, so check the current price on Amazon before deciding. On features alone, I’d favor the Mackie for a noisy workspace, but neither model’s listed details establish that it includes a call microphone.
