If you want superior connectivity stability, a lighter weight for all-day comfort, and a sleek design that feels less bulky during extended wear, choose MARLALL Swimming Headphones-Bone Conduction; if you need maximum battery endurance for long travel days, a larger internal storage capacity for extensive offline libraries, and robust physical buttons for easy control with wet hands, choose SAMVEK Swimming Headphones.
• MARLALL excels in lightweight comfort (22.68g) and features the latest Bluetooth 5.4 chip for stable wireless connections on land, but requires you to switch to MP3 mode for any underwater use.
• SAMVEK offers a longer 8-hour playback window on a single charge and supports a wider variety of audio formats for your offline library, though it is slightly heavier and uses a more traditional button layout.
• Best For: Choose MARLALL if you prioritize wearing comfort and seamless switching between dry land and water; choose SAMVEK if you are a heavy media consumer who needs hours of uninterrupted play and precise file management without touching a screen.
The MARLALL S800 is engineered specifically for the swimmer who values comfort above almost everything else. At just 22.68 grams, this device is remarkably light, utilizing premium liquid silicone material to create a skin-friendly seal that conforms to your ear shape. This isn't just about weight; it is about eliminating pressure points. When you are treading water or doing laps for an hour, you often forget these headphones are there because they do not press tightly against your ear canal. The open-ear bone conduction design ensures you can still hear your surroundings, which is a critical safety feature whether you are in a busy pool or swimming in open water while snorkeling.
Its connectivity setup is equally thoughtful for the modern athlete. Powered by Bluetooth 5.4, it promises strong interference resistance and a reliable connection up to 10 meters when you are out of the water. This makes it ideal for transitioning from a run to a swim without fumbling with settings. You must switch to the built-in 32 GB MP3 mode for any underwater activity. Once you have loaded your playlists onto the device via the magnetic charging cable, the transition is seamless, allowing you to dive in without losing your audio track.
This product is best suited for people who swim frequently and need a device that stays put without causing irritation. The nano-coated sealed design protects against saltwater and chlorine damage, ensuring longevity even in harsh environments. If you are someone who gets frustrated with headphones that feel heavy or cause pain after 30 minutes of use, the MARLALL is the logical choice. It is also perfect for travelers who want a single device that handles both their airport gym sessions and their hotel pool workouts without needing multiple pieces of gear. Just remember to dry the microphone after every swim to ensure call quality remains crisp when you surface.

The SAMVEK X7 targets a different user profile: the endurance athlete or the frequent traveler who prioritizes battery life and content variety over ultra-minimalist weight. With a 200mAh battery, this model delivers up to 8 hours of continuous playback or talk time after a two-hour charge. This is a significant advantage for long-haul flights or marathon training sessions where you might be away from a power source for the entire day. While other devices might require a mid-session recharge, the SAMVEK keeps going, making it a reliable companion for those who spend hours moving.
Storage and format flexibility are where this unit truly shines. It comes with 32 GB of internal memory, which the manufacturer states can hold up to 8,000 songs depending on compression, supporting a wide range of formats including MP3, WMA, WAV, APE, and FLAC. This means you don't need to worry about converting files before transferring them to the headphones. The multi-function button design allows you to navigate this vast library easily, even with wet hands. You can double-click the power button to switch modes, or use the dedicated controls to play, pause, skip tracks, and answer calls. The physical buttons provide a tactile experience that many users find reassuring compared to touch-sensitive surfaces that can be finicky when wet.
However, this capability comes with a trade-off in weight and form factor. Weighing 30 grams, it is slightly heavier than the MARLALL, and its over-ear style with Acrylonitrile Butadiene Styrene construction gives it a more substantial presence. This might not bother everyone, but for those who are extremely sensitive to weight on their head, it is a factor to consider. The IP68 rating confirms it is completely waterproof, capable of withstanding immersion up to 2 meters deep, making it safe for diving and snorkeling. It is the ideal pick for someone who wants to load up their device with a massive playlist before a trip and never think about charging until they get home.
• Best for battery life → SAMVEK Swimming Headphones, offering up to 8 hours of playback versus the standard duration implied by the smaller battery in the competitor, making it superior for long travel days.
• Best for weight and comfort → MARLALL Swimming Headphones-Bone Conduction, at only 22.68 grams, it is significantly lighter and uses liquid silicone for a softer feel than the ABS plastic build of the SAMVEK.
• Best for file format support → SAMVEK Swimming Headphones, explicitly listing support for high-quality formats like FLAC and APE alongside standard MP3s, whereas the MARLALL focuses on general MP3 compatibility.
• Best for connection stability → MARLALL Swimming Headphones-Bone Conduction, featuring the latest Bluetooth 5.4 chip designed for superior interference resistance and reliable performance up to 10 meters.
• Best for intuitive control → SAMVEK Swimming Headphones, with its dedicated multi-function physical buttons that allow for easy mode switching and track navigation without relying on touch.
• Best for post-swim durability → MARLALL Swimming Headphones-Bone Conduction, with its specific mention of a nano-coated sealed design and instructions to dry the microphone to prevent call issues, emphasizing long-term care.
• Best for storage capacity → Both offer 32 GB, but the SAMVEK highlights the ability to store up to 8,000 songs and supports drag-and-drop file management directly from a computer drive.
• Best for travel versatility → MARLALL Swimming Headphones-Bone Conduction, due to its lightweight profile and magnetic charging cable that doubles as a data transfer tool, making it easier to pack and manage.
In my opinion, I would choose the MARLALL Swimming Headphones-Bone Conduction for most buyers. While the SAMVEK offers impressive battery life, the sheer difference in weight and the premium feel of the liquid silicone material make the MARLALL a much better daily driver. I prefer a device that disappears on my head, especially when traveling for airplane trips where comfort during long layovers matters. The Bluetooth 5.4 connectivity also feels more future-proof for non-swimming activities. That said, if you are planning a week-long trip and need a device that won't die before you get back to your hotel, the SAMVEK's 8-hour battery is a compelling alternative. Ultimately, the MARLALL strikes the better balance between comfort, safety, and performance for the average user.
Yes, both models are suitable for air travel. The MARLALL is particularly well-suited due to its lightweight design, which reduces fatigue during long flights, while the SAMVEK offers extended battery life for those who plan to listen to music for the entire duration of a long-haul journey.
No, both units come with a magnetic charging cable that connects to your computer, allowing you to access the internal storage as a hard drive. You can simply drag and drop your MP3 files into the folder to update your playlist without needing additional adapters.
No, neither model supports Bluetooth transmission underwater. Water blocks the signal, so you must switch to the built-in MP3 mode using the 32 GB internal memory for any swimming, snorkeling, or diving activities.
Both products carry an IP68 waterproof rating, meaning they are dustproof and can withstand complete immersion. The MARLALL specifically mentions a nano-coated sealed design to resist pool and saltwater damage, ensuring the internal components remain protected.
