If you want flexible app-linked controls and a stated 30-hour charging-case battery life for workout, choose Jiawu Headphones; if you need touch controls and an LED battery display for workout, choose ZRATFWLJMDK Earphones. Jiawu offers more listed functions, while ZRATFWLJMDK keeps its appeal focused on sport-oriented listening and quick battery checks. Neither sheet gives enough information to compare call clarity or water resistance confidently.
• Jiawu Headphones’ biggest strength: The listed app-linked functions include music control, volume adjustment, custom sound effects, and headphone finding. Trade-off: The sheet specifies a 30-hour case battery life but does not describe an LED battery readout.
• ZRATFWLJMDK Earphones’ biggest strength: Their charging case has an LED digital display for checking the remaining battery. Trade-off: No listening-time or total case-battery figure is provided.
• Jiawu suits: Buyers who want extra controls and a stated daily listening and case-battery figure.
• ZRATFWLJMDK suits: Buyers who prioritize touch operation, a visible battery readout, and a sports-focused in-ear design.
Jiawu’s strongest case is its range of listed controls and companion-app functions. The feature set includes answering calls, adjusting volume, changing tracks, remote photography, finding the earbuds, and switching languages. It also lists custom sound effects and a customizable charging-case watch face through a mobile app. That gives the product more to explore than a simple pair of earbuds with basic playback controls.
For a workout, the touch area is described as easy to operate with one hand, including blind movements while exercising. That could matter when you want to make a quick adjustment without reaching for your phone. The battery details are unusually specific: the earbuds are listed for six hours of listening a day, with up to 30 hours from the charging case. The case itself has a 300mAh battery, while each earbud has a 30mAh battery. Those figures give buyers a clearer planning point, though they do not establish how long a single charge lasts under every pattern of use.
Jiawu is the one I’d consider if app options, hands-on control, and stated battery capacity matter more to you than a visible battery display. The listed wireless transmission distance is about 10 meters, which gives a rough idea of the intended connection range. Who should skip it: Skip Jiawu if you specifically want an LED case display or need documented water resistance, since neither is stated in its product information.
ZRATFWLJMDK keeps its listed feature set centered on exercise and straightforward wireless use. The in-ear design is described as lightweight plastic, with a fit intended to stay secure during activities such as jogging and fitness training. The sheet also describes a dynamic speaker unit and stereo playback, but it does not provide technical audio measurements or enough detail to establish how the sound compares with Jiawu’s.
Its clearest practical distinction is the LED digital display on the charging case. That screen is meant to show the remaining battery for the earbuds and case, so you can check the charge before heading outside or starting a session. Touch controls are listed for switching tracks, answering calls, and changing volume. In principle, that combination is useful when your phone is tucked away during exercise; the sheet does not say whether the controls can be customized.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Updated: 2026-10-23 · 7 min read · Independent comparison
The earbuds use Bluetooth and are described as compatible with Bluetooth-enabled smartphones, tablets, and laptops. That gives them a broad stated range of uses, from commuting to workouts and everyday listening. Who should skip them: Skip ZRATFWLJMDK if you need a documented listening-time figure, a stated case capacity, or a companion-app feature list; those details are not provided.
• Best for a stated case-battery figure → Jiawu Headphones. The sheet gives a 30-hour battery life for the charging case and says the earbuds support six hours of listening a day. ZRATFWLJMDK does not list comparable runtime figures.
• Best for checking charge at a glance → ZRATFWLJMDK Earphones. Their case has an LED display intended to show the remaining battery for both the earbuds and charging box. Jiawu’s sheet does not mention a display that reports battery status.
• Best for app-linked extras → Jiawu Headphones. The listed options include custom sound effects, language switching, remote photography, and finding the earbuds, along with music and volume controls.
• Best for uncomplicated touch controls → ZRATFWLJMDK Earphones. Track switching, call answering, and volume adjustment are specifically listed as touch-panel functions.
• Best for a workout when you want control without your phone → Either, for different reasons. Jiawu describes one-handed blind touch operation during movement; ZRATFWLJMDK emphasizes tap controls and a fit intended for exercise.
• Best for buyers who want a case customization option → Jiawu Headphones. The companion app can be used to customize the charging-case watch face. That is an extra personalization feature, not a battery or sound advantage.
• Best for broad Bluetooth-device use → ZRATFWLJMDK Earphones. Their sheet names smartphones, tablets, and laptops as compatible devices. Jiawu’s information gives a transmission distance but does not provide the same device list.
• Best for avoiding assumptions about call quality → Neither earns a clear win. Both list call-related functions, but neither provides call-quality measurements or enough detail to establish which is clearer in noisy surroundings.
A workout earbud choice is not just about the feature list. It is also about which information you need before you leave home. Jiawu provides a stated listening and case-battery figure, which can help with rough charging plans. ZRATFWLJMDK offers a case display intended to show remaining charge. One gives a runtime estimate; the other offers a visual check. Those are useful but different kinds of reassurance.
Fit is another point to weigh carefully. ZRATFWLJMDK describes a lightweight in-ear design intended to remain secure during jogging and fitness training. Jiawu is also listed as in-ear, and its sheet highlights touch operation during movement. Neither sheet supplies a fit range, ear-tip options, or a formal water-resistance rating, so I would not assume either one is a better match for every ear or suitable for heavy sweat exposure.
The search for foldable in ear headphones for workout does not map neatly onto either product: both are described as in-ear earbuds, and neither sheet says that it folds. Likewise, shoppers looking for the best USB-C charging earphones for workout should check the charging details before choosing. Jiawu includes a charging cable in the package list, but the connector type is not stated. ZRATFWLJMDK’s connector type is also not specified.
Call features deserve similar caution. Both products list call answering, but that alone does not tell us how well voices come through in a busy gym or on a windy outdoor run. If your priority is finding the best crystal clear calls earphones for workout, neither sheet provides microphone specifications or call-quality evidence that would justify naming a winner. The honest comparison is that calls are supported as a control function, while call clarity remains unestablished.
My Verdict
I would choose Jiawu Headphones for workout use because its stated case battery life and broader list of app-linked controls make the decision easier to plan around. The one-handed touch operation also fits the practical need to make a quick adjustment while moving. I’d pick ZRATFWLJMDK instead if a visible battery display and a sports-focused fit description matter more to me than documented runtime. My recommendation is Jiawu, with the important caveat that neither sheet establishes water resistance or call clarity.
I’d lean toward Jiawu if you value a stated case-battery figure and extra app functions. ZRATFWLJMDK is a sensible alternative if you want its LED case display and touch controls for exercise.
Jiawu lists six hours of listening a day and up to 30 hours of battery life from the charging case. ZRATFWLJMDK provides an LED battery display but no listening-time or total case-runtime figure, so the available details do not support a direct runtime comparison.
The provided product details do not specify noise cancellation or a water-resistance rating for either pair. I would not assume either feature is present based only on their workout-oriented descriptions.
Both list call answering, and ZRATFWLJMDK describes a dynamic speaker unit with stereo audio. Neither sheet gives microphone specifications or measured call and sound quality, so there is not enough information to say which provides clearer calls or better overall audio.
