If you want a lightweight, foldable wired headset for simple listening on the move, choose FOSA Head Mounted Headphone; if you need USB-C compatibility and a built-in volume limit for running, choose Kensington USB-C Hi-Fi Headphones. Neither is designed specifically for running, and neither is an open-ear or ear-clip style, but Kensington is the more practical match if your device uses USB-C and you want its stated 94 dB listening limit.
For the most straightforward portable option, I’d pick FOSA for its 3.5 mm connection and compact folding design. Kensington is the stronger fit for school, work, or compatible USB-C devices, with a longer cord and clearer safety-focused specifications.
If you want a lightweight, foldable wired headset for simple listening on the move, choose FOSA Head Mounted Headphone; if you need USB-C compatibility and a built-in volume limit for running, choose Kensington USB-C Hi-Fi Headphones. Neither is designed specifically for running, and neither is an open-ear or ear-clip style. For that use, the main differences are their connections, folding design, cord length, and listening-level limiter.
• FOSA’s biggest strength: a foldable, adjustable design with rotatable ear cups and a 3.5 mm wired connection. Trade-off: its listed features do not include a volume limiter or a stated cord length.
• Kensington’s biggest strength: USB-C compatibility across several operating systems, plus a built-in maximum audio level of 94 dB. Trade-off: it is not described as foldable, and its USB-C connector is less suited to devices that only have a 3.5 mm headphone jack.
• Choose FOSA for a compact headset that connects through a standard 3.5 mm jack and supports TF card playback.
• Choose Kensington for school, work, and USB-C devices where the longer cord and stated listening-level limit are useful.

FOSA is a simple over-ear wired headset built around adjustability and portability. Its headband adjusts, its ear cups rotate, and the headset folds down for easier carrying. Soft, breathable padded ear cups are part of the design, which makes it a reasonable option for casual music, videos, or other everyday listening where a basic, compact headset is enough.
Its 3.5 mm connection is useful if your device has a matching headphone jack. The listed compatibility includes smartphones, tablets, MP3 and MP4 players, and laptops. It also supports TF card playback. The audio specifications include a 20 Hz–20,000 Hz frequency range and a 32-ohm impedance, but those figures alone do not establish how it will sound in every situation.
I’d consider FOSA for someone who wants a straightforward wired headset that can fold for a bag or drawer. It is not the natural choice if USB-C is the only available audio connection, or if a stated safe-listening limiter is a priority. And for running, its over-ear form is a different proposition from open ear earbuds for running or ear clip headphones for running: the data does not describe an open-ear or clip-on design.
Kensington is an over-ear wired headset with a USB-C connection. It is listed as compatible with USB-C devices running Windows, macOS, iOS, Android, and Chrome OS. That makes it a more direct fit for a laptop, tablet, or other compatible device without a 3.5 mm headphone jack. Its six-foot cord also gives the listener more room to move around a desk or classroom setup than a short lead would.
The headset has 40 mm drivers, a padded adjustable headband, and foam ear pads covered in soft leatherette. Kensington also specifies a maximum audio level of 94 dB through a safe-listening limiter. That is a concrete distinction from FOSA, whose listed features do not specify a volume limit. The frequency range is listed as 20 Hz–20,000 Hz, but driver size and frequency range should not be treated as a guarantee of a particular listening experience.
I’d look at Kensington for schoolwork, video calls, or office listening on a USB-C device, particularly when a stated volume limit matters. The trade-off is that it is a wired, over-ear headset, not a running-specific design. Its connection also means it is not the straightforward pick for a device that has only a 3.5 mm jack.
• Best for a foldable design → FOSA Head Mounted Headphone. Its ear cups rotate and its body folds to a more compact form for carrying.
• Best for USB-C devices → Kensington USB-C Hi-Fi Headphones. Compatibility is specified across Windows, macOS, iOS, Android, and Chrome OS when the device has USB-C.
• Best for a standard 3.5 mm headphone jack → FOSA Head Mounted Headphone. Its listed connection is a 3.5 mm jack.
• Best for a longer specified cord → Kensington USB-C Hi-Fi Headphones. Its cord is six feet long; FOSA’s listed details do not give a cord length.
• Best if a volume limit matters → Kensington USB-C Hi-Fi Headphones. It has a stated maximum audio level of 94 dB. No equivalent limit is listed for FOSA.
• Best for TF card playback → FOSA Head Mounted Headphone. TF card support is included among its listed features.
• Best for a simple school or desk setup → Kensington USB-C Hi-Fi Headphones. The USB-C connection, six-foot cord, and listening-level limiter suit that kind of use.
• Best for running → neither is a dedicated running pick. Both are over-ear wired headsets, and the specifications do not describe open-ear or ear-clip construction.
I’d choose Kensington USB-C Hi-Fi Headphones if I wanted one of these for a compatible USB-C laptop or tablet, especially for school or desk listening. The six-foot cord and specified 94 dB limit give it a clearer practical case for that role.
For running, I would not mistake either over-ear headset for a purpose-built option. If I had to choose between them, I’d favor FOSA only when its 3.5 mm connection and foldable design fit the device and carry setup. My recommendation for running is Kensington when USB-C compatibility and its volume limit matter, but neither has an open-ear or ear-clip design.
