If you want more onboard music storage for college students, choose RELAXYO Bone Conduction Swimming; if you need longer stated battery life, choose ANSTEN Swimming Headphones. For students who move between a pool, a run, and everyday listening, the deciding difference is simple: RELAXYO has 32GB of MP3 storage, while ANSTEN lists up to eight hours of playback.
Both use an open-ear bone-conduction design and support Bluetooth 5.4, but neither streams Bluetooth underwater. For swimming, you need to switch to MP3 mode and play music stored on the headphones.
• RELAXYO’s biggest strength: 32GB of built-in MP3 storage, with the manufacturer estimating space for up to 7,000 songs. Trade-off: its stated battery life is up to seven hours, and swimming requires MP3 mode.
• ANSTEN’s biggest strength: up to eight hours of listening or calls on a full charge. Trade-off: its 8GB MP3 memory is much smaller than RELAXYO’s.
• Both: IP68-rated, open-ear bone-conduction headphones with Bluetooth 5.4 and MP3 playback for swimming.
• Choose RELAXYO if keeping a large offline music library on the headphones matters most.
• Choose ANSTEN if you prefer the longer stated runtime and want its included accessories, which list ear tips and adjustable elastic straps.
RELAXYO is the storage-focused choice. Its 32GB of built-in memory is listed as enough for up to 7,000 songs, giving a student more room to carry an offline library without depending on a phone connection. The listed transfer method is straightforward: connect the included magnetic charging cable to a computer and move music files to the headphones. A double press of the power button switches between Bluetooth and MP3 modes.
That setup makes sense for pool sessions, where Bluetooth cannot transmit underwater. Switch to MP3 mode before swimming, and your stored tracks are the relevant feature. RELAXYO also has an IP68 waterproof rating and an open-ear design with a flexible memory-titanium frame. The product information says it can be worn with a swim cap or goggles and is intended for activities such as swimming, running, cycling, surfing, fishing, and hiking.
The trade-off is battery life: RELAXYO lists up to seven hours of music after a 1.5-hour charge. Its three-button control scheme handles playback, volume, calls, mode changes, and voice-assistant access, but students wanting the longest stated runtime should compare that figure with ANSTEN’s eight hours. I’d skip RELAXYO if a larger MP3 library is not useful to you and battery runtime is the priority.
ANSTEN is the more appealing option if you want a little more stated listening time between charges. It lists up to eight hours of music or calls, with a full charge taking about two hours. Its MP3 memory is 8GB, described as space for up to 1,500 songs. That is less than RELAXYO’s listed capacity, but it still gives you an offline library for swimming.
The operating rule is the same: Bluetooth 5.4 is useful for a connection in suitable surroundings, but Bluetooth does not transmit underwater. For swimming, use MP3 mode and music stored on the headphones. ANSTEN has an IP68 rating and an open-ear bone-conduction design, and its product information says it can be used with swim caps, goggles, and earplugs. It is also described for running and cycling, where an open-ear layout leaves the ear canal unobstructed.

• Best for a quicker stated charge → RELAXYO Bone Conduction Swimming. Its charge time is listed as 1.5 hours, compared with about two hours for ANSTEN.
• Best for swimming without a phone connection → Either, with MP3 mode. Both include onboard storage, and both require stored music rather than Bluetooth streaming underwater.

ANSTEN is a sensible alternative if its extra stated hour of battery life matters more than storage. But for my pick as a best headset for college students who specifically want swim-ready, stored music, I’d take RELAXYO.
