If you want open-ear listening for outdoor workouts and situational awareness, choose Syohoxi Ultra-Comfortable Open-Ear sport; if you need compact earbuds designed for sleep, choose Ertuly Sleep Earbuds. For audiophiles choosing between them, the deciding factor is how and where you plan to listen: Syohoxi keeps your ear canals open, while Ertuly puts noise cancellation and a small in-ear fit first.
Syohoxi Ultra-Comfortable Open-Ear sport vs Ertuly Sleep Earbuds at a Glance
• Ertuly’s biggest strength: Small in-ear earbuds with ANC, shaped with overnight and side-sleeping use in mind. Trade-off: Their snug in-ear design does not offer Syohoxi’s open-ear awareness.
• Choose Syohoxi if your listening happens mainly during exercise, especially outdoors, where hearing traffic or other nearby sounds matters.
• Choose Ertuly if you want earbuds for sleep, relaxation, or reducing everyday noise, and prefer a compact in-ear fit.
• These are built around different priorities, not the same job: workout awareness versus quieter, more discreet listening.
Syohoxi is the exercise-focused option. Its open-ear placement leaves the ear canals free, and its bone-conduction drivers deliver audio through the cheekbones. That design is useful when you want music or calls without shutting out all surrounding sound. During an outdoor run or cycle, awareness of nearby traffic and other activity can matter as much as having audio playing. In a gym, it may also help you hear instructions around you.
The listed Bluetooth version is 5.3, and the stated wireless range is 10 meters. For a typical workout, that gives you a wireless setup without a headphone jack; the controls are buttons rather than touch controls. Syohoxi is listed at 28 grams. Its lightweight open-ear hooks are described as having a silicone coating and an ergonomic fit, so the design is aimed at staying in place through movement without inserting a bud into the ear canal.
Battery life is stated as up to 8 hours of music after a 2-hour charge. A 5-minute charge is described as providing up to half an hour of playback, which could be handy when you realize shortly before leaving that the headphones need power. The IP56 rating is intended for sweat and rain exposure, not swimming. That makes the pair suitable to consider for an outdoor workout in changeable weather, but not for use in a pool.

Syohoxi also includes built-in call noise cancellation, described as filtering wind and gym noise. That is a call feature, not a promise that music listening will cancel surrounding noise. In fact, the open-ear design is chosen to preserve environmental awareness, so it is a poor match if your main goal is to block out a noisy room.
Who should skip Syohoxi: Skip it if you want ANC for sleep or a more isolated in-ear listening experience.
Ertuly is designed for people who want small earbuds for rest and relaxation. Its in-ear buds weigh a stated 3 grams each, and the product information describes a compact fit intended to feel unobtrusive during overnight use. That focus will appeal to side sleepers who find larger headphones inconvenient against a pillow. Still, fit is personal: the sleep-oriented design is not a guarantee that every listener will find an in-ear bud comfortable in every sleeping position.
The listed feature that most clearly separates Ertuly from Syohoxi is active noise cancellation. It is intended to reduce disturbances such as snoring, city noise, and household sounds, making the earbuds a more relevant choice when you want a quieter sleep or relaxation environment. ANC should not be treated as complete silence, but it gives Ertuly a purpose that Syohoxi’s open-ear design does not serve. If you are searching for sleep headphones for audiophiles, this pair’s strongest case is the combination of a compact in-ear design and noise cancellation—not an open, workout-ready fit.
Ertuly uses Bluetooth 5.4 and has touch controls. Its stated wireless range is 33 feet. The battery is specified for up to 6 hours of continuous playback, with up to 30 hours total when the charging case is included. The case has an LED display for checking the power levels of the earbuds and case. These details matter if you use the buds regularly: the case provides additional listening time between charges, while the display makes battery status visible.
The supplied items include two sleep earbuds, four earplugs, a cable, and a user manual. The listed driver type is dynamic. Those specifications identify the hardware, but they do not establish a particular sound signature or guarantee audiophile-level sound quality. Ertuly’s core design priority is overnight comfort and noise reduction, rather than the environmental awareness that defines Syohoxi.
Who should skip Ertuly: Skip it if you need open-ear awareness for outdoor exercise or want stated sweat-and-rain protection.
• Best for outdoor workout awareness → Syohoxi Ultra-Comfortable Open-Ear sport. Its open-ear design leaves the ear canals free, so it is the clearer fit for running or cycling when you want to hear nearby activity.
• Best for sleep-focused listening → Ertuly Sleep Earbuds. Its compact in-ear shape and ANC are directed toward quieter rest and relaxation.
• Best for a stated longer single listening session → Syohoxi Ultra-Comfortable Open-Ear sport. It lists up to 8 hours of music, compared with Ertuly’s up to 6 hours of continuous playtime.
• Best for additional listening time from a case → Ertuly Sleep Earbuds. Its listed total is up to 30 hours with the charging case, and the case includes an LED battery display.
• Best for sweaty or rainy workouts → Syohoxi Ultra-Comfortable Open-Ear sport. Its IP56 rating is intended for sweat and rain, but it is not suitable for swimming.
• Best for active noise cancellation → Ertuly Sleep Earbuds. Ertuly lists ANC for reducing disturbances; Syohoxi lists call noise cancellation, which serves a different purpose.
• Best for someone avoiding an in-ear fit → Syohoxi Ultra-Comfortable Open-Ear sport. Its open-ear placement does not require buds inside the ear canals.
• Best for a stated longer wireless range → Ertuly Sleep Earbuds. The listed range is 33 feet, compared with Syohoxi’s 10 meters.
Start with the setting where you will use the headphones most. For outdoor exercise, Syohoxi’s open-ear construction is a practical distinction, not just a styling choice. It allows ambient sound to reach your ears while audio plays. That may suit a route where you want to stay more aware of traffic or other people. It also means you should not expect the same isolation as an ANC earbud.
Ertuly makes the opposite trade. It sits inside the ear and includes active noise cancellation to reduce surrounding disturbances. That is a better match for resting in a noisy home or trying to settle down near city sounds, but it does not provide the same open-ear awareness. If you are looking for the best ANC wireless headset for audiophiles, Ertuly is the only one of these two that lists ANC. That does not, by itself, establish which one sounds better: the sheets identify Syohoxi’s bone-conduction driver and Ertuly’s dynamic driver, but do not provide comparable sound tests or detailed sound-quality measurements.
Think about moisture separately from noise control. Syohoxi lists IP56 protection for sweat and rain, with an explicit limitation against swimming. Ertuly’s data does not list a waterproof rating. If your routine involves sweaty workouts or unpredictable weather, that makes Syohoxi the more clearly specified option. If you mainly listen while lying down or relaxing indoors, its sports protection may be less relevant than Ertuly’s compact fit and ANC.
My Verdict
I would choose Syohoxi if I wanted one of these for regular outdoor workouts: its open-ear design, stated IP56 sweat-and-rain protection, and up-to-8-hour listening figure fit that job well. For audiophiles, I would still make the choice by use case rather than assume either driver type guarantees better sound. If my main need were overnight comfort and a quieter environment, I would choose Ertuly instead for its compact sleep-oriented design and ANC.
No. Syohoxi lists an IP56 rating for sweat and rain, and its product information says it is not suitable for swimming. Ertuly’s listed details do not specify a waterproof rating.
