If you want wired earbuds for work with a simple 3.5 mm connection, choose LUDOS Zenith; if you need the same wired setup in green rather than black, choose LUDOS Zenith. These are two color versions of the same basic earbud design, so the practical choice is straightforward: pick the finish you prefer.
For work, their wired connection, in-ear fit, call controls, and sound-isolation design are the useful details to weigh. Neither version is listed with active noise cancelling or bone conduction, so those needs point beyond this pair.
• LUDOS Zenith, black: In-ear wired design with a 3.5 mm jack, call control, and a five-year warranty; the trade-off is that it needs a compatible jack and has no listed active noise cancelling.
• LUDOS Zenith, green: The same core wired features and warranty, with a listed 20 Hz–20,000 Hz frequency range; the trade-off is that it shares the same wired connection and sound-isolation approach.
• Black is for: someone who wants the listed core features in a black finish.
• Green is for: someone who prefers green and wants the frequency range stated in the product information.
• Neither is for: shoppers who specifically need wireless listening, active noise cancelling, or bone conduction.
The black LUDOS Zenith is a corded, in-ear earbud with a 3.5 mm jack and a dynamic driver. Its 32-ohm impedance is one of the audio specifications provided, while the product information describes detailed sound with spatial or directional audio for music, movies, and games. For work, that makes it a simple option to consider for listening and calls when your device has a compatible jack.
The control details include call control and a button-style controller. The earbuds use sound isolation, which is a different approach from active noise cancelling: the listed feature is isolation, not electronic cancellation. A five-year warranty is also specified. Those details may appeal if you prefer a direct wired setup and want a stated warranty period rather than a wireless model with additional connectivity features.

Who should skip it: Skip the black version if you need Bluetooth, active noise cancelling, bone conduction, or a device connection other than a 3.5 mm jack. The data does not specify a microphone performance level, cable length, or any water-resistance rating, so those should not be assumed.
The green LUDOS Zenith shares the black version’s in-ear design, dynamic driver, 32-ohm impedance, 3.5 mm wired connection, call control, button-style controller, sound isolation, and five-year warranty. Its product information also lists a frequency range of 20 Hz–20,000 Hz. That gives shoppers an additional stated audio specification, though it does not by itself establish how the earbuds will sound to every listener.
At work, the main appeal is still the direct connection and simple control setup. The green finish is the clearest difference between the two versions; the listed core features otherwise match. The product description also positions the earbuds for music, movies, and games, with detailed sound and spatial or directional audio. If you want an in-ear wired pair and prefer green, this version fits that brief without adding a different connection type or noise-control system.
Who should skip it: Skip the green version if green is not the finish you want, or if your work setup requires wireless use or active noise cancelling. The listed frequency range is not a promise of a particular sound signature, and no microphone specifications or cable length are provided.
• For a black finish → LUDOS Zenith. The black version is identified as black in its product details.
• For a green finish → LUDOS Zenith. Choose this version if green better suits your preference.
• For a 3.5 mm wired connection → either one. Both are listed as wired earbuds with a 3.5 mm jack.
• For call controls → either one. Call control and a button-style controller are listed for both.
• For sound isolation → either one. Both list sound isolation; neither lists active noise cancelling.
• For a stated frequency range → green LUDOS Zenith. Its product information specifies 20 Hz–20,000 Hz; that range is not listed for the black version.
• For the same stated warranty period → either one. Both list a five-year warranty.
• For wireless listening or bone conduction → neither. Both are wired, in-ear earbuds, not wireless or bone-conduction headphones.
Before choosing either pair for work, check the connection on the device you plan to use. Both versions rely on a 3.5 mm jack. If your computer, phone, or other device does not have that connection, the stated product information does not establish that an adapter is included or that another connection method is supported. A wired setup avoids relying on wireless connectivity, but it also means you are tied to a compatible jack while listening.
Think about what “noise control” means for your workplace. These earbuds list sound isolation, not active noise cancelling. That distinction matters if you work near steady background noise and are specifically searching for active noise cancelling sports earbuds for work. The available details do not claim that either version electronically cancels noise, and neither is described as a sports-focused model. They may still suit ordinary listening in a work setting, but the listed features do not establish how much surrounding sound will be reduced.
The same distinction applies to bone conduction. Someone searching for the best bone conduction headphones for work is looking for a different design category from these in-ear earbuds. The Zenith models sit inside the ear and use a dynamic driver. If your priority is an open-ear listening style, neither color version matches that stated design.
For calls, both versions list call control and a button-style controller, and the product title identifies a microphone. Those details support considering them for work calls, but the data does not provide microphone pickup patterns, call-noise processing, or other call-quality measurements. I would not choose between black and green based on an assumed microphone difference; no such difference is listed.
Finally, treat the stated audio details as specifications, not a guarantee that one version will sound better. The green model lists a 20 Hz–20,000 Hz frequency range, while both versions list a 32-ohm impedance and a dynamic driver. The black model’s product description also refers to detailed and spatial or directional audio. Since the core design is otherwise closely matched, the clearest decision factors are finish and whether the green model’s additional stated frequency information matters to you.
My Verdict
Both are listed with the same 3.5 mm wired connection, in-ear design, dynamic driver, call control, sound isolation, and five-year warranty. Their stated differences are the finish and the green version’s listed 20 Hz–20,000 Hz frequency range.
No active noise cancelling feature is listed for either version. Both specify sound isolation, which should not be treated as the same feature as electronic noise cancellation.
Both versions list a microphone in the product title and call control in the product details. They may suit a compatible device and a basic wired-call setup, but the available specifications do not describe microphone quality or call-noise processing.
Confirm that your device has a compatible 3.5 mm jack, and choose the finish you prefer. If you need wireless listening, bone conduction, or active noise cancelling, these listed features do not meet that requirement. For the current price, check Amazon.
