If you want open-ear listening for everyday wear and low-impact workouts, choose Amazon Renewed SHOKZ OpenMove; if you need waterproof headphones with stored music for swimming, choose MARLALL Swimming Headphones-Bone Conduction. For audiophiles comparing these designs, the decisive difference is how you listen: OpenMove pairs with a Bluetooth device, while MARLALL switches to MP3 mode underwater.
Amazon Renewed SHOKZ OpenMove vs MARLALL Swimming Headphones-Bone Conduction at a Glance
• Amazon Renewed SHOKZ OpenMove: A lightweight, open-ear design with a wraparound titanium frame and six hours of battery life; its main limitation is that the stated use and fit focus on low-impact activity, not swimming.
• MARLALL Swimming Headphones-Bone Conduction: IP68 waterproofing and 32 GB of built-in MP3 storage make it the swimming-focused pick; Bluetooth audio does not work underwater, so swimming means switching to stored music.
• OpenMove is for: Anyone who wants Bluetooth music, calls, and podcasts while keeping their ears open for surroundings.
• MARLALL is for: Swimmers who want to bring audio into the water without relying on a Bluetooth signal.
• The key trade-off: Choose OpenMove for straightforward Bluetooth listening and a six-hour stated battery life; choose MARLALL for water-focused use and onboard storage, with more mode-switching to manage.
OpenMove is a bone-conduction headset designed to sit outside the ears rather than seal them with earbuds. Its wraparound titanium frame is intended to keep the headset in place through low-impact activities such as light jogging, as well as everyday commutes. That makes it a practical fit for someone who wants audio without fully blocking nearby sounds. It is also described for music, calls, and podcasts, so its role can extend beyond a workout.
The stated battery life is six hours, with a two-hour charge time. That gives a buyer a useful planning point: a shorter workout or commute fits comfortably within the stated listening window, while a long day of repeated listening may require charging between sessions. Bluetooth connectivity supports listening from a paired device; the product information lists Bluetooth 4 and no headphone jack. The audio is delivered through the cheekbone, and the sound description emphasizes balanced audio and bass, though this open-ear format is not the same listening experience as sealed over-ear headphones.

Who should skip it: Skip OpenMove if you need headphones specifically designed for swimming or want more than six hours of stated battery life between charges.
MARLALL Swimming Headphones-Bone Conduction: Who It's For
MARLALL is the more specialized option. Its IP68 waterproof rating and swimming-focused instructions make it the clear match for someone who wants audio during swims, snorkeling, or other water activities named in its product details. The critical condition is that Bluetooth cannot transmit underwater. You need to switch to MP3 mode for swimming, using the built-in 32 GB storage rather than streaming from a phone. That distinction matters more than the Bluetooth version if the main purpose is pool listening.
Outside the water, MARLALL supports Bluetooth 5.4, with a stated range of up to 10 meters, for music, audiobooks, and hands-free calls with compatible iOS and Android devices. The built-in storage gives it another use: you can load audio for a workout where carrying a connected phone is inconvenient. The supplied magnetic charging cable also connects to a computer for access to internal storage and playlist updates. Unlike OpenMove’s stated six-hour battery figure, the supplied information does not give MARLALL a battery-life duration, so I wouldn’t assume one.
The design uses silicone and is described as lightweight, with a listed item weight of 22.68 g. Its open-ear bone-conduction approach does not plug the ear canal, while the product details also mention adjustable straps. After swimming, the microphone should be dried to help prevent call problems. This small care step is worth remembering if you plan to switch from pool sessions to calls. The product information describes an adult age range, so I would not treat it as a children’s model simply because the fit is open-ear.
Who should skip it: Skip MARLALL if you expect to stream Bluetooth audio while swimming, or if you want a stated battery-life figure before choosing.
• Best for swimming with stored audio → MARLALL. Its IP68 waterproof rating and MP3 mode are specifically relevant in the water, where Bluetooth signals cannot transmit.
• Best for Bluetooth listening without a swim-specific setup → OpenMove. It is designed for music, calls, and podcasts through Bluetooth and has no MP3 storage listed.
• Best for a stated battery-life figure → OpenMove. The supplied information specifies six hours of use and a two-hour charge time; MARLALL’s battery duration is not stated.
• Best for onboard music storage → MARLALL. Its 32 GB memory lets you load audio for swimming or phone-free exercise.
• Best for low-impact daily movement → OpenMove. The wraparound titanium frame is described as staying in place during light jogging and everyday commutes.
• Best for a newer listed Bluetooth version → MARLALL. Its Bluetooth 5.4 specification and stated 10-meter range suit compatible-device listening on land.
• Best if you want a simple open-ear Bluetooth routine → OpenMove. It avoids the specific underwater switch between Bluetooth and MP3 modes.
• Best for a pool-and-land mix → MARLALL, with a caveat. Use MP3 mode underwater and Bluetooth on land; remember the guidance to dry the microphone after swimming.
I would buy MARLALL if swimming is a regular part of the plan: waterproofing and onboard MP3 storage address the central problem that Bluetooth cannot work underwater. For audiophiles, though, neither product promises the enclosed, traditional headphone experience; these are bone-conduction designs that put convenience and open-ear use first. If my routine were mainly commuting and low-impact exercise, I’d choose OpenMove for its straightforward Bluetooth use and stated six-hour battery life.
Before choosing, be honest about where you will listen most. If you mainly want audio while walking, commuting, or doing low-impact exercise, OpenMove’s open-ear Bluetooth setup is the simpler match. You can listen to music, podcasts, or calls from a connected device, and the six-hour battery figure gives you a clear reference for how often you may need to recharge. If your priority is swimming, that convenience does not replace waterproofing or a way to play audio without Bluetooth.
For MARLALL, think about whether you are comfortable managing separate listening modes. Bluetooth is for compatible-device use on land; MP3 mode is required underwater. You will also need to put audio on the built-in storage, rather than expect a phone stream to carry through the water. That is a useful arrangement for a pool session, but less direct if you want to change tracks from a connected device while swimming.
Sound expectations deserve a moment too. Bone conduction keeps the ear canal open, which can suit people who dislike earbuds or want to remain aware of nearby sounds. But an open-ear bone-conduction design should not be chosen on the assumption that it behaves like a sealed over-ear model. Neither product sheet establishes comparative sound measurements or claims a specific level of noise isolation. If rich, isolated listening is your priority, weigh that limitation before choosing either one.
These are also not interchangeable with every style a shopper might search for. Someone looking for wireless kids headphones for audiophiles should note that both product details describe an adult age range; neither sheet identifies either model as a children’s product. And someone searching for the best gaming headphones for audiophiles may want to consider that these are sport-oriented bone-conduction headphones, not products described with gaming-specific features. OpenMove lists a video-game theme in its style information, but that alone does not establish gaming-focused performance or compatibility.
If you are weighing value, first decide which features you would actually use, then check the current price on Amazon. I would not pay extra for waterproofing and stored music if I never swim, just as I would not choose a non-swimming-focused headset for regular pool use. For a closer comparison, also consider that OpenMove provides a 90-day limited warranty description, while MARLALL lists a one-year warranty. Those stated warranty periods may matter to a buyer, but they do not change the core difference: OpenMove is oriented toward everyday Bluetooth listening, and MARLALL is built around swimming with MP3 playback.
No. Its product information says Bluetooth signals cannot transmit underwater, so swimming requires MP3 mode. Bluetooth 5.4 and the stated 10-meter range apply to compatible-device use outside the water.
OpenMove has a stated battery life of six hours and a stated charge time of two hours.
Both are described for hands-free calls on land. MARLALL’s instructions say to dry the microphone after swimming to help prevent call issues; OpenMove lists six hours for music, calls, and podcasts.
No. Both use bone conduction and an open-ear approach rather than a conventional cup that covers the ears. OpenMove uses a wraparound titanium frame; MARLALL uses a silicone design and includes adjustable straps.
