If you want built-in music storage for swimming and an especially light silicone design, choose MARLALL Liquid Silicone Swimming; if you need a stated 10-hour battery life for commuting, choose SCPTEA Bone Conduction Headphones. For commuting, the SCPTEA is the more clearly specified everyday option, while the MARLALL makes more sense when swimming and offline music are priorities.
• MARLALL’s biggest strength: 32 GB of built-in MP3 storage lets you play music while swimming, when Bluetooth cannot transmit underwater. Trade-off: its listed details do not give a battery runtime.
• SCPTEA’s biggest strength: a stated playback time of up to 10 hours, plus an open-ear fit designed to keep you aware of surrounding sounds. Trade-off: the product details do not specify built-in storage capacity or MP3 playback.
• Both use open-ear bone conduction and Bluetooth 5.4, with a stated wireless range of up to 10 meters.
• Choose MARLALL if swimming with stored music is central to your routine and you want a lightweight silicone frame.
• Choose SCPTEA if your routine involves commuting and you want a stated battery duration alongside a lightweight, secure-fit design.
MARLALL is the more swim-focused choice of the two. Its main practical advantage is the built-in 32 GB of storage for MP3 playback. Bluetooth signals cannot transmit underwater, so its instructions say to switch to MP3 mode when swimming. That makes the storage more than a side feature: it is what allows you to bring music into the pool without relying on a wireless connection.
The open-ear bone-conduction design leaves the ears uncovered rather than placing earbuds inside them. The frame is described as lightweight, and its enclosure material is silicone. The listed weight is 22.68 grams, while the product description also refers to a 29-gram design. Since those figures differ, I would not treat a precise weight comparison as settled; either way, the product is presented as a lightweight option. Its Bluetooth 5.4 connection is specified for use up to 10 meters, and it supports wireless music, audiobooks, and hands-free calls when connected to a compatible iOS or Android device.
I would look at MARLALL if swimming is a regular part of your routine and you specifically want stored music for use in the water. It may also suit someone who wants open-ear headphones for outdoor activities such as cycling or hiking. I would skip it if a clearly stated battery runtime is essential to your decision, or if commuting is your main use and you want a published playback figure to plan around. The available details do not specify MARLALL’s battery life.

SCPTEA is the more straightforward everyday and commuting pick on paper. Its open-ear bone-conduction design keeps the ears uncovered, and its stated playback time is up to 10 hours. That gives a commuter a useful reference point for thinking about a workday, travel, or a combination of errands and exercise. The product also specifies Bluetooth 5.4 and a wireless range of up to 10 meters.
The listed frame weight is 28 grams, and the design is described as secure during activities such as running, cycling, workouts, and daily use. Its 16-millimeter drivers are identified in the product information, while the feature description emphasizes keeping the ears open to surrounding sounds. Magnetic charging is included, and the listed battery capacity is 180 mAh. The product is also described as IPX8 waterproof for swimming and sports.
I would consider SCPTEA if you want a single open-ear pair for commuting, workouts, and general daily listening, especially if knowing the stated battery duration matters. It may be a sensible option for someone searching for the best ear clip headphones for commuting, though these products are bone-conduction headphones rather than conventional ear clips. I would skip it if your key requirement is confirmed onboard MP3 storage for swimming: the provided details do not specify that feature or a storage capacity.
• Best for swimming with music stored on the headphones → MARLALL. Its 32 GB of built-in storage and MP3 mode address the limitation of Bluetooth underwater.
• Best for a stated battery runtime → SCPTEA. It is specified for up to 10 hours of continuous playback; no runtime is provided for MARLALL.
• Best for commuting with a published playback figure → SCPTEA. The 10-hour claim gives you a concrete battery reference for travel and everyday listening.
• Best for a silicone enclosure → MARLALL. Its enclosure material is listed as silicone, whereas SCPTEA’s is plastic.
• Best for a clearly specified driver size → SCPTEA. Its product information lists 16-millimeter drivers; MARLALL’s listed details do not give a driver size.
• Best for MP3 listening away from a phone → MARLALL. The 32 GB onboard storage supports stored music, including in swimming mode.
• Best fit for an all-around workout and commute routine → SCPTEA. Its listed features combine open-ear listening, a secure fit, magnetic charging, and up to 10 hours of playback.
• Best if you want one of the lightest listed designs → MARLALL, with a caveat. Its listed weight is 22.68 grams, but another description gives 29 grams; SCPTEA is listed at 28 grams.
The phrase “in ear headphones for commuting” often describes what shoppers type when they want a convenient everyday pair. Neither of these is an in-ear design: both use open-ear bone conduction. That distinction matters if you specifically want something seated inside the ear canal. If you want your ears uncovered, both are closer to that goal, with SCPTEA having the clearer battery specification for a commute.
Neither product lists noise control beyond “none.” I would not choose either on the expectation of blocking traffic, office chatter, or other surroundings. Their open-ear approach is instead suited to listening while remaining more connected to nearby sounds. That can be useful on a commute, but it also means they are not a substitute for noise-isolating headphones when quiet listening is the priority.
Water resistance is another point to consider in context. MARLALL is described as IP68 waterproof, while SCPTEA is described as IPX8 waterproof. Those labels are not identical, and the supplied information does not establish which one is better for every swimming situation. MARLALL has the clearer swimming-specific music feature because it specifies MP3 mode and 32 GB of storage. SCPTEA is also described for swimming, but the details do not state that it can play stored music underwater.
For calls and wireless listening outside the water, both list Bluetooth 5.4 and a range of up to 10 meters. SCPTEA’s description specifically mentions hands-free calls and commuting, while MARLALL also describes calls and streaming when connected. The core difference is not the Bluetooth version; it is the role each pair is better equipped to fill. MARLALL has the more explicit offline swimming setup, and SCPTEA has the more explicit battery and everyday-use details.
My Verdict
For my commuting-focused choice, I would pick SCPTEA because its up-to-10-hour playback claim gives me a practical battery reference, and its open-ear design suits everyday listening. I also like that the stated use cases include commuting, workouts, and cycling rather than focusing mainly on swimming. If swimming with stored music were my main need, I would choose MARLALL instead for its 32 GB MP3 mode. The right pick comes down to whether your routine is centered on the commute or the pool.
