If you want open-ear earbuds with longer stated playtime and adjustable hooks for the gym, choose Anker Soundcore AeroFit 2; if you need kid-focused, volume-limited headphones for a child’s sports and outdoor listening, choose iClever OWS01. The AeroFit 2 is the more suitable adult workout pick; the OWS01 puts child-oriented listening controls first. Neither is an in-ear noise-isolating design, so you can remain aware of what is happening around you.
Anker Soundcore AeroFit 2 vs iClever OWS01 at a Glance
• Anker Soundcore AeroFit 2: Open-ear fit, four adjustable hook positions, directional audio and up to 42 hours with the case. Trade-off: it has no listed noise control, so it is not designed to shut out a busy gym.
• iClever OWS01: Lightweight, flexible open-ear headphones with child-focused volume limits and physical controls. Trade-off: its listed audience is kids, and its sheet does not provide a total listening time.
• For a gym routine: I’d choose AeroFit 2 for its adjustable fit and much longer stated battery life across the earbuds and case.
• For a child’s active listening: OWS01 is the more relevant fit because its design and volume settings are aimed at kids.
The AeroFit 2 is an open-ear option for someone who wants music without sealing the ear canal. Its double-curved design and soft materials are intended for comfort, while the ear hooks have four adjustment positions. That adjustable fit is a practical advantage for workouts: you can position the hooks to suit your ears rather than relying on a single fixed shape. The open design also lets outside sound reach you, which may be useful when exercising around other people or moving outdoors.

I’d consider it for an adult who wants an adjustable open-ear fit for workouts, walking or longer listening sessions. I’d skip it if your priority is active noise cancellation or a more isolated, in-ear sound. Its listed noise control is none, and keeping your surroundings audible is part of the design rather than a flaw to overlook.
The OWS01 is explicitly designed for kids. It uses an open-ear, air-conduction approach, with soft TPE and a three-point pressure-dispersion design. A flexible memory-steel section at the back is described as bending through 360 degrees without deformation. The product sheet also lists a weight of 0.8 ounces, making low weight a clear part of its everyday-use pitch for children.
Its standout feature is its child-oriented volume limiting, with settings listed at 74 and 85 dBA. It uses physical controls for volume and playback, and Bluetooth 5.4 for wireless connection to compatible devices. The 14.2 mm dynamic drivers and Dynamic Range Control are intended to provide clear audio with enhanced bass, but the sheet gives no battery runtime figure. That makes it harder to judge how well it suits a full day away from a charger.
For a child listening to audio at home, on a trip, or during outdoor activities, those safety-focused controls and flexible construction may be appealing. For an adult choosing the best wireless headset for gym use, I would not treat the OWS01 as a direct match for an adult workout headset: its sizing and priorities are child-focused, and the product information does not list adjustable hooks or a total playtime.
Side-by-Side: Which Should You Choose?
• For adult gym workouts → Anker Soundcore AeroFit 2. The adjustable hooks give you four positions to work with, and the open-ear fit avoids sealing the ear canal.
• For a child’s listening → iClever OWS01. Its design is explicitly for kids, with volume limits and simple physical controls.
• For longer stated battery life → Anker Soundcore AeroFit 2. The listed figures are up to 10 hours on a charge and up to 42 hours with the case. OWS01’s data sheet does not state a runtime.
• For an adjustable ear-hook fit → Anker Soundcore AeroFit 2. Its four-position hook system is a specific fit feature; the OWS01 instead uses a flexible back-hanging design.
• For physical playback and volume buttons → iClever OWS01. Its controls are described as physical buttons. AeroFit 2 uses touch controls.
• For wireless charging → Anker Soundcore AeroFit 2. Its case can recharge on a wireless charger; no wireless-charging case feature is listed for the OWS01.
• For a “best sweat resistant bluetooth headset for gym” shortlist → Anker Soundcore AeroFit 2, with an important caveat. It has an IP55 rating in its product title, while the OWS01 sheet does not state an IP rating. That makes AeroFit 2 the better-supported option on this point, but check the manufacturer’s care guidance for your use.
The broad query “best earbuds for gym” can hide two different needs. Some shoppers want an adult-friendly fit, a predictable battery plan and music during a workout. Others are buying for a child and care more about volume limits, flexibility and straightforward controls. These two products serve those different jobs, so the label “open ear” alone should not decide it.
There is also a meaningful sound-use distinction. AeroFit 2 lists directional audio intended to guide sound toward the ear and minimize leakage. OWS01 lists air conduction and DRC, with 14.2 mm drivers. Neither data sheet supports a claim that either headset cancels gym noise; the AeroFit 2 explicitly lists no noise control. If your routine depends on blocking loud surroundings, these are not the right designs to choose on that basis.
I’d buy the Anker Soundcore AeroFit 2 for the gym. Its four-position hooks, open-ear design, stated 10-hour earbud playtime and 42-hour total with the case make it the stronger fit for an adult workout routine. The iClever OWS01 has worthwhile child-focused strengths, especially its volume limits and flexible build, but it is aimed at a different wearer. For my gym pick, AeroFit 2 is the clearer match.
