If you want open-ear comfort and a lighter-feeling fit for exercise, choose Yamdrok Y1; if you need longer total playback between charges, choose UPUNAIS Ear Buds.
For workouts where awareness of surrounding sounds matters, Yamdrok’s open-ear design is the more fitting choice; UPUNAIS’s in-ear hook design is the better match if you prefer an earbud that sits in the ear.
Yamdrok Y1 vs UPUNAIS Ear Buds at a Glance
• Yamdrok Y1’s biggest strength: an open-ear clip design that avoids ear-canal pressure; its trade-off is 30 hours of stated total playback, less than UPUNAIS’s 50 hours.
• UPUNAIS Ear Buds’ biggest strength: up to 50 hours with the case; its trade-off is an in-ear fit, which may not suit someone seeking an open-ear listening style.
• Yamdrok Y1: 13 mm dynamic drivers, six hours per charge, IPX4 resistance, and a digital display showing the earbuds’ and case’s power levels.
• UPUNAIS Ear Buds: 12 mm dynamic drivers, five hours per charge, IPX4 resistance, and an LED display for earbud and case battery levels.
• Choose Yamdrok for open-ear exercise listening; choose UPUNAIS if your priority is longer stated total playtime and an in-ear fit.
Yamdrok Y1 is built around a flexible C-shaped clip that rests around the ear, with an open-ear earpiece rather than an in-ear tip. That design is the key distinction for exercise. If you dislike the feeling of an earbud sealing or pressing into your ear canal, the Y1’s layout offers a different kind of fit. Its nylon-and-silicone construction and touch controls are intended for everyday listening as well as workouts.
The battery figures are six hours per charge and 30 hours in total with the case. A digital display shows power levels for both earbuds and the case, which is useful if you want a quick battery check before heading out. The 13 mm dynamic drivers are larger than UPUNAIS’s listed 12 mm drivers, but driver size alone does not prove which one will sound better. Yamdrok also lists ENC for calls, wind-noise reduction, Bluetooth 6.0, and IPX4 resistance against sweat and splashes.
I’d consider Yamdrok for someone who wants open-ear headphones for exercise, especially if ear-canal pressure is a deal-breaker. It also makes sense for walks or workouts where an open-ear design feels preferable. Skip it if your main aim is the longer stated case-assisted playback of these two, or if you specifically want an in-ear earpiece. Its stated total is 30 hours, not 50.
UPUNAIS takes the more conventional in-ear route, adding an ear-hook shape for a secure fit during workouts. That combination suits someone who prefers an earbud seated in the ear but wants the hook to help hold it in place during movement. The product information lists silicone for the enclosure and includes an eartip, cable, and user manual in the package.
Its headline advantage is up to 50 hours of playback when using the charging case. The listed battery life per charge is five hours, so the longer total depends on returning the earbuds to the case between listening sessions. An LED display shows remaining power for the earbuds and case. The 12 mm dynamic drivers are paired with ENC for calls, Bluetooth 6.0, and IPX4 sweat and splash resistance.
I’d look at UPUNAIS if you want clip on earbuds for exercise in the sense of an ear-hook design, and you favor an in-ear fit over an open-ear one. It may also suit someone who wants fewer case recharges across a longer stretch of use. Skip it if you are specifically avoiding an in-ear structure, or if six hours of stated playback per charge matters more to you than the longer total with the case.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Side-by-Side: Which Should You Choose?
• Prefer an open-ear fit for exercise → Yamdrok Y1. Its earpiece is listed as open and rests on the ear with a flexible C-shaped bridge. UPUNAIS is listed as in-ear.
• Want the longer total playback figure → UPUNAIS Ear Buds. The stated total is up to 50 hours with the case, compared with Yamdrok’s 30 hours.
• Want more stated listening time per charge → Yamdrok Y1. Its listed figure is six hours per charge, versus five for UPUNAIS. Total runtime and single-charge runtime answer different needs.
• Prefer an ear hook around an in-ear bud → UPUNAIS Ear Buds. Its hook-shaped earpiece is designed to stay put during training, while Yamdrok uses an open-ear clip.
• Need moisture resistance for gym sessions or light rain → Either. Both list IPX4 resistance, so both are described as suitable for sweat and splashes. Neither specification establishes protection against immersion.
• Want a battery display → Either. Both cases have a display for power levels; Yamdrok calls its display digital, while UPUNAIS describes an LED display.
• Want the larger listed driver → Yamdrok Y1. Its driver is 13 mm against UPUNAIS’s 12 mm. That size difference is a specification, not a reliable standalone verdict on sound quality.
• Looking for sports earbuds for exercise with ENC calls → Either. Both list environmental noise cancellation for calls. Yamdrok additionally specifies wind-noise reduction, while neither sheet gives a comparable call-quality measurement.
The most practical decision is therefore not about which driver number looks more impressive. It is about how you want the earbuds to sit, and whether you prioritize longer single-charge listening or longer case-assisted total playback. If your exercise routine includes long stretches away from a charging case, Yamdrok’s six-hour figure is relevant. If you routinely return the earbuds to the case and want a higher stated overall total, UPUNAIS has the advantage on paper.
In my opinion, I’d choose Yamdrok Y1 for exercise because its open-ear clip design is the more distinctive fit, and its six-hour per-charge figure edges UPUNAIS’s five hours.
I’d choose UPUNAIS instead if I preferred an in-ear hook and valued its stated 50-hour total with the case more than open-ear comfort.
For my own pick between these two, the fit difference matters more than the driver-size gap or display style.
That makes Yamdrok my recommendation for someone who wants exercise listening without an in-ear earpiece.
Both are described for sports use and list IPX4 resistance. Yamdrok has an open-ear clip; UPUNAIS has an in-ear structure with an ear hook, so the better fit depends on which style you prefer.
UPUNAIS lists up to 50 hours with its charging case, compared with Yamdrok’s 30 hours. Yamdrok lists six hours per charge, while UPUNAIS lists five, so Yamdrok has the longer stated single-charge figure.
Both list IPX4 resistance, which is described as protection against sweat and splashes. The specifications do not claim that either product is waterproof for immersion.
The available specifications do not establish a clear sound-quality winner. Yamdrok lists 13 mm dynamic drivers and bass-enhancement features; UPUNAIS lists 12 mm dynamic drivers and describes balanced sound. Driver size alone cannot settle the comparison.
If you want open-ear comfort and a lighter-feeling fit for exercise, choose Yamdrok Y1; if you need longer total playback between charges, choose UPUNAIS Ear Buds.
For workouts where an open-ear design is your preference, Yamdrok is the clearer fit. UPUNAIS is the better match if you want an in-ear earbud with an ear hook.

Yamdrok Y1: Who It's For
Yamdrok Y1 uses a flexible C-shaped clip that rests around the ear, with an open-ear earpiece rather than an in-ear tip. That difference is central to choosing it. If you dislike the feeling of an earbud sitting in your ear canal, the Y1 offers a different approach to listening during a workout. Its listed nylon-and-silicone construction and touch controls also make it a candidate for everyday use beyond exercise.
The battery figures are six hours per charge and 30 hours total with the case. A digital display shows the power levels of both the earbuds and the case, making it easy to check the remaining charge at a glance. Yamdrok lists 13 mm dynamic drivers, environmental noise cancellation for calls, wind-noise reduction, Bluetooth 6.0, and IPX4 resistance. The larger driver figure is a specification, not proof that it will sound better than UPUNAIS.
I’d consider Yamdrok if you want on-ear headphones for exercise and prefer an open-ear design to an in-ear fit. The flexible clip is also worth considering if you want to avoid ear-canal pressure. Skip it if your main priority is the longer stated total playback of the two, or if you specifically want an in-ear earbud with a hook. Its listed total is 30 hours, not 50.
UPUNAIS uses an in-ear structure with an ear hook, a combination intended to hold the earbuds securely during workouts. That makes it a more natural choice for someone who likes an earbud seated in the ear but wants the hook to help keep it in place during movement. Its product information lists a silicone enclosure and includes an eartip, cable, and user manual.
Its main advantage on paper is up to 50 hours of playback with the charging case. The listed life per charge is five hours, so reaching the larger total means returning the earbuds to the case between sessions. An LED display shows the remaining battery level of the earbuds and case. UPUNAIS also lists 12 mm dynamic drivers, Bluetooth 6.0, IPX4 sweat and splash resistance, and environmental noise cancellation for calls.
• Prefer an open-ear fit for exercise → Yamdrok Y1. Its earpiece is listed as open and sits on the ear with a flexible C-shaped bridge. UPUNAIS is listed as in-ear.
• Want the longer stated total playback → UPUNAIS Ear Buds. Its total is up to 50 hours with the case, compared with Yamdrok’s 30 hours.
• Want more stated listening time per charge → Yamdrok Y1. Yamdrok lists six hours per charge; UPUNAIS lists five. Single-charge time and case-assisted total are different measures.
• Prefer an ear hook with an in-ear bud → UPUNAIS Ear Buds. Its hook shape is designed for a secure fit during training, while Yamdrok uses an open-ear clip.
• Want earbuds described for sweat and light splashes → Either. Both list IPX4 resistance. That specification does not mean they are suitable for immersion.
• Want a case display for battery checks → Either. Yamdrok lists a digital display, while UPUNAIS describes an LED display; both show power levels for the earbuds and case.
• Want the larger listed driver → Yamdrok Y1. It lists 13 mm dynamic drivers versus UPUNAIS’s 12 mm. Driver size alone cannot establish which will sound better.
• Want sports earbuds for exercise with ENC for calls → Either. Both list environmental noise cancellation for calls. Yamdrok also specifies wind-noise reduction, but neither provides a comparable call-quality measurement.
The specs make fit and battery use the most useful points of comparison. If you tend to listen for several hours without returning the earbuds to their case, Yamdrok’s six-hour per-charge figure may matter more. If you recharge by placing the earbuds in the case between sessions and care about the stated overall total, UPUNAIS has the advantage.
Neither design is a universal winner. The open-ear clip and in-ear hook serve different preferences, and the battery figures tell different stories depending on how you use the case. I’d decide based on which fit you want first, then use the battery figures as the tie-breaker.
My Verdict
I’d choose UPUNAIS if I preferred an in-ear hook and valued its stated 50-hour total with the case more.
The driver-size difference and display style would be secondary for me.
For my pick between these two, the open-ear fit makes Yamdrok the more compelling option.
Both are described for sports use and list IPX4 resistance. Yamdrok has an open-ear clip; UPUNAIS has an in-ear structure with an ear hook, so the better fit depends on which style you prefer.
UPUNAIS lists up to 50 hours with its charging case, compared with Yamdrok’s 30 hours. Yamdrok lists six hours per charge, while UPUNAIS lists five, giving Yamdrok the longer stated single-charge figure.
Both list IPX4 resistance, described for sweat and splashes. The specifications do not claim that either product is suitable for immersion.
The listed specifications do not establish a clear sound-quality winner. Yamdrok lists 13 mm dynamic drivers and bass-enhancement features; UPUNAIS lists 12 mm drivers and describes balanced sound. Driver size alone cannot settle the comparison.
