If you want a simple wired fit with a 3.5 mm connection for running, choose Koss R10; if you need open-ear wireless listening that keeps your surroundings audible, choose iClever OWS01. The key difference is not a close call in format: the R10 is an on-ear wired headphone, while the OWS01 is a kid-focused, Bluetooth open-ear design.

For a run where you want a cable-free fit and awareness of nearby sounds, I’d choose the OWS01. Pick the Koss if your priority is wired listening and an adjustable headband rather than an open-ear sports design.

The Koss R10 is a straightforward, wired on-ear headphone. Its 3.5 mm plug gives it a direct connection to compatible laptops, tablets, and gaming devices, and its adjustable headband lets the wearer alter the fit. The padded leatherette cushions and lightweight design are aimed at comfortable listening, while the listed 30 Hz–20 kHz range covers a broad span of audio frequencies.
That setup makes sense for someone who wants a simple wired option and does not need Bluetooth. It may suit desk listening, travel, or gaming when a compatible device is nearby. The cable also means there is no need to pair it wirelessly, but it can get in the way during movement.
For running, the R10 is the less natural fit of these two. It is an on-ear model with a wired connection, and the supplied information does not describe a sports-specific fit or water resistance. I would skip it if you need a wireless, open-ear design or want to keep both ears uncovered to hear your surroundings.
The iClever OWS01 is a kid-focused open-ear headphone that connects over Bluetooth 5.4. Rather than sitting inside the ear, its air-conduction design keeps the ears uncovered. That can be useful when a child needs to hear nearby people or sounds while listening. It has 14.2 mm dynamic drivers, physical buttons for playback and volume, and a flexible back section made with memory steel wire.
Its lightweight construction and three-point pressure design are intended to support comfortable wear, while the flexible frame is described as bendable. The listed volume limits are 74 and 85 dBA. Those features, along with its child-oriented design, make it the more relevant choice for a young listener who needs wireless audio for travel, school, or outdoor activities.
Side-by-Side: Which Should You Choose?
• Best fit for a child who needs open ears → iClever OWS01. Its open-ear design is intended to let surrounding sound remain audible.
• Best for wireless listening → iClever OWS01. It uses Bluetooth 5.4 and has no headphone jack.
• Best for a direct wired connection → Koss R10. Its 3.5 mm plug works with compatible devices without Bluetooth pairing.
• Best for an adjustable headband → Koss R10. Its headband can be adjusted; the OWS01 instead uses a flexible back-hanging section.
• Best for physical playback and volume buttons → iClever OWS01. Its controls are push buttons intended to be simple for children to use.
• Best for a cable-free run → iClever OWS01. Its wireless design avoids a headphone cable, though it is a kids’ model and running fit is not specified.
• Best for a wired commute or desk setup → Koss R10. It is a conventional on-ear design with a 3.5 mm connection.
• Best choice if “deep bass ear clip headphones for running” is your search → neither is an exact match. The R10 is not an ear-clip design, and the OWS01 is an open-ear kids’ headphone. iClever describes its driver and sound processing as enhancing bass, but the supplied details do not establish a particular bass level.
My Verdict
I’d choose the Koss R10 for a compatible wired setup, not as my first pick for a run. Neither product is presented as a general-purpose adult sports headphone, so I would match the choice to the listener and intended fit rather than assume either is built for every running routine.
FAQ
For a child who wants wireless listening and an open-ear design, the OWS01 is the more relevant option. The R10 is wired and on-ear. Neither product’s listed details establish water resistance or a dedicated running fit.
The R10’s listed connectivity is wired through a 3.5 mm jack. Although Bluetooth appears in one style field, the supplied connectivity details identify the connection as wired, so it should not be treated as a Bluetooth headphone.
The OWS01 lists no noise control. Its open-ear design leaves the ears uncovered, which is different from electronic noise cancellation or an in-ear transparency mode.
The OWS01’s description says its sound processing enhances bass, but the supplied specifications do not quantify how much bass it produces. The Koss lists a 30 Hz–20 kHz frequency range and describes a full sound profile; neither set of details proves which will sound bassier to a particular listener.
