If you want open-ear awareness with a feather-light fit for running, cycling and long outdoor sessions, choose ASHATA Sport Headphone; if you need an ultra-thin in-ear set with noise-cancelling calls and a charging case for study, work and gaming, choose Jiawu Earbuds Featherlight Design.
• ASHATA Sport Headphone — biggest strength: an open-ear air conduction design that keeps your ears unplugged so you can hear traffic, trail and training partners while you listen.
• ASHATA Sport Headphone — biggest trade-off: no microphone, so it is a listening-only device — calls are off the table.
• Jiawu Earbuds Featherlight Design — biggest strength: a genuinely ultra-thin in-ear build (6mm thick, 8mm wide) plus ENC noise cancelling and integrated microphones for calls.
• Jiawu Earbuds Featherlight Design — biggest trade-off: in-ear sealing means you are cut off from your surroundings, which is the opposite of what outdoor athletes usually want.
• Who ASHATA is for: runners, hikers and cyclists, or anyone who wears headphones for hours and wants to avoid blocking the ear canal.
• Who Jiawu is for: students, remote workers and gamers who want discreet, slim earbuds with call clarity and a charging case.
The ASHATA Sport Headphone is built around one idea: keep the ear canal open. Instead of pushing a tip into your ear, it sits outside and uses air conduction to deliver sound. That single design decision changes almost everything about how you use it. You hear your music, and you also hear the car behind you, the cyclist calling out, or the person running next to you. For outdoor training, that is not a small detail — it is the whole point.
The weight is the other headline. At roughly 13g (0.46oz), it is light enough that ASHATA frames it as an all-day listening device, and the construction — ABS with skin-friendly silicone — is aimed at sweat, movement and repeated use rather than desk duty. The ergonomic open-ear shape is described as staying put during high-intensity sport, and it is designed to work alongside glasses and helmets. If you ride with a helmet or run with sunglasses, that compatibility matters more than any spec sheet number.
Who should buy it: runners, hikers, cyclists, and long-session listeners who want situational awareness and a barely-there fit. Who should skip it: anyone who needs to take calls, because there is no microphone, and anyone who wants total sound isolation — an open-ear design deliberately does the opposite.
Jiawu Earbuds Featherlight Design: Who It's For
Jiawu takes the other route to "lightweight": instead of sitting outside the ear, these are in-ear buds trimmed down to almost nothing. The sheet puts them at just 6mm thick and 8mm wide at the maximum, with a nude finish, and the stated goal is pressure-free wear for long study blocks or workdays. If you have ever pulled out traditional buds after three hours because your ears felt sore, that thin profile is the selling point.
Feature-wise, Jiawu leans into sound and calls rather than sport. The buds are tuned for what the brand calls IMAX-style cinematic audio, with the emphasis on clarity and depth for music and calls. More practically, they include ENC noise cancelling with integrated microphones, so your voice is picked up clearly in noisy rooms — a real advantage for calls from a busy home, café or shared office.
Battery is handled by the case: 600mAh in the charging case and 45mAh in each earbud, with a 120-hour standby figure and a one-hour charge time. In practice, that means the case is your refuel point and the buds top up quickly between sessions. Connectivity is Bluetooth 5.4, which is the newer standard here. The package includes a 2-pack of earphones, the charging case, a charging cable and a manual.
Who should buy it: students, remote workers, gamers and commuters who want slim, unobtrusive earbuds with call clarity and a case that keeps them topped up. Who should skip it: outdoor athletes who need to hear traffic, and anyone who dislikes the plugged-ear feeling of in-ear buds.
• Best for outdoor safety and awareness → ASHATA Sport Headphone. The open-ear, air conduction design lets ambient sound in by default.
• Best for calls and meetings → Jiawu Earbuds Featherlight Design. ENC noise cancelling plus integrated microphones; ASHATA has no microphone at all.
• Best for running, hiking and cycling → ASHATA Sport Headphone. Ergonomic open-ear fit, glasses- and helmet-friendly, built for high-intensity movement.

• Best for battery convenience → Jiawu Earbuds Featherlight Design. A 600mAh charging case, 45mAh per bud, one-hour charge time and 120-hour standby.
• Best for situational awareness while listening for hours → ASHATA Sport Headphone. At 13g, it is designed to stay comfortable all day without sealing your ears.
• Best for newer wireless standard → Jiawu Earbuds Featherlight Design. Bluetooth 5.4 versus ASHATA's 5.2.
• Best for ear-health-conscious listeners → ASHATA Sport Headphone. No insertion into the ear canal, which the sheet ties to avoiding discomfort and hearing strain.
In my opinion, the deciding question is not which is lighter — both are engineered to feel minimal — but whether you want your ears open or sealed. If you train outdoors, I would buy the ASHATA Sport Headphone: the open-ear air conduction design, 13g build and helmet/glasses compatibility are exactly what running and riding demand, and the missing microphone is a fair trade for that awareness. If your listening happens at a desk, in class or during calls, I recommend the Jiawu Earbuds Featherlight Design — the ultra-thin in-ear fit, ENC call clarity and charging case suit that life far better. Pick the one that matches where you actually listen.
No. The data sheet lists no microphone, so it is a listening-only device. If calls matter, the Jiawu Earbuds are the better match because they include integrated microphones with ENC noise cancelling.
ASHATA states roughly 13g (0.46oz) for its open-ear design, while Jiawu emphasises an ultra-thin in-ear profile at 6mm thick and 8mm wide. Both are built around the idea of near-weightless wear, just in different form factors.
ASHATA Sport Headphone. Its open-ear design keeps you aware of traffic, and it is described as staying in place during high-intensity sport and compatible with glasses and helmets — something in-ear buds like the Jiawu are not designed for.
Jiawu publishes the more detailed battery story: a 600mAh charging case, 45mAh per earbud, 120-hour standby and a one-hour charge time. ASHATA's sheet focuses on Bluetooth 5.2 range and stability rather than battery figures, so if runtime details matter to you, check the current listings on Amazon before deciding.
