If you want a swim-ready, phone-free headset for Switch workouts and open-ear awareness, choose HIFI WALKER Bone Conduction Headphones; if you need longer case-supported playback, in-ear isolation, and call-focused features, choose Acjohtin Earbuds. For a Switch, the HIFI WALKER is the more distinctive fit when you want to keep your ears open or listen away from a phone, while Acjohtin is the conventional everyday wireless-earbud choice.
HIFI WALKER Bone Conduction Headphones vs Acjohtin Earbuds at a Glance
• Acjohtin’s biggest strength: In-ear sound, ear hooks, and up to 90 hours of total playback with the charging case; trade-off: IPX7 protection covers sweat, splashes, and light rain, not the swimming use described for HIFI WALKER.
• For Switch use: HIFI WALKER can pair over Bluetooth, but neither product’s supplied details establish dedicated Switch compatibility or a wired connection.
• Choose HIFI WALKER for swimming, open ears, and phone-free music; choose Acjohtin for workouts, calls, and case-supported listening between charges.
HIFI WALKER Bone Conduction Headphones: Who It's For
HIFI WALKER is built around a different idea from ordinary earbuds: its bone-conduction drivers sit in an open-ear design, leaving the ear canals uncovered. That can suit someone who wants audio while still being more aware of nearby sounds, such as a coach, a lifeguard, or traffic. The adjustable tension band is intended to help keep the fit stable during movement.
Its strongest distinction is swimming. The headphones have an IPX8 rating, and the product information specifies continuous immersion up to 2 meters. They also include 32GB of internal storage for MP3 playback, which matters because Bluetooth cannot transmit underwater. In practical terms, a swimmer can leave a phone outside the pool area and use the stored music instead. The listed battery life is 8 hours, with a stated 2-hour charging time.
For Switch players, the Bluetooth 5.3 connection offers a possible wireless listening route, but the supplied information does not say that the headset is specifically designed or certified for Switch. I would consider it if open-ear wear, swimming, or listening without carrying a phone is central to the decision. I would skip it if your priority is an in-ear seal, a charging case with extended combined playback, or confirmed platform-specific compatibility.
Acjohtin takes the familiar in-ear route, adding flexible over-ear hooks and interchangeable S, M, and L silicone tips. That combination is aimed at keeping the earbuds secure through running, cycling, and workouts. Its IPX7 rating is described for sweat, splashes, and light rain, so the intended use is exercise and daily travel rather than swimming underwater.
The product also includes Bluetooth 6.1, four microphones with ENC noise reduction for calls, touch controls, and 16.2mm dynamic drivers. These features make it the more conventional pick for someone who wants in-ear listening, phone calls, and a secure fit in one set. For Switch, the Bluetooth connection may be relevant, but the product details do not specify Switch compatibility or give a wired option. Skip it if you need open ears or an explicitly swim-oriented design.

Swimming is its clearest point of difference. The headphones have an IPX8 rating, and the product details specify continuous immersion up to 2 meters. They also include 32GB of internal storage for MP3 playback. Because Bluetooth does not work underwater, that storage is the relevant feature for listening in a pool: music can be played from the headset rather than streamed from a phone nearby. The listed battery life is 8 hours, and the stated charging time is 2 hours.
For Switch players, Bluetooth 5.3 offers a possible wireless listening route, but the supplied information does not say that the headset is designed or confirmed for Switch. I would consider it if swimming, open-ear wear, or listening without carrying a phone is central to the decision. It may also appeal to someone who wants a headset for Switch sessions but dislikes the feel of in-ear tips. I would skip it if an in-ear seal, case-supported playback, or confirmed platform-specific compatibility is essential.
Acjohtin takes the familiar in-ear route, adding flexible over-ear hooks and interchangeable S, M, and L silicone tips. That setup is intended to help the earbuds stay in place during running, cycling, and workouts. Its IPX7 protection is described for sweat, splashes, and light rain, making it an exercise and everyday-travel option rather than the swimming choice in this comparison.
The battery setup is one of its main advantages. Acjohtin lists up to 8 hours of playback from a full earbud charge and up to 90 hours total when the charging case is included. An LED display shows the battery levels for the earbuds and case. For someone who uses earbuds throughout a busy day, the case-supported total may mean fewer charging interruptions than a headset whose listed battery life is 8 hours without a stated case total.
The feature set also includes Bluetooth 6.1, four microphones with ENC noise reduction for calls, touch controls, and 16.2mm dynamic drivers. These details make Acjohtin the more conventional pick for someone who wants in-ear listening, phone calls, and a secure workout fit. For Switch, its wireless connection may be relevant, but the product information does not specify Switch compatibility or a wired option. Skip it if you need open ears, phone-free MP3 playback, or a design described for swimming.
• Best for swimming laps → HIFI WALKER Bone Conduction Headphones. Its IPX8 rating and MP3 storage make it the clear match. Bluetooth is not supported underwater, so the built-in music mode is the one to use in the pool.
• Best for workout listening with a charging case → Acjohtin Earbuds. They list up to 8 hours per charge and up to 90 hours total with the case, plus an LED display for checking battery levels.
• Best for keeping your ears uncovered → HIFI WALKER Bone Conduction Headphones. Its open-ear design leaves the ear canals free. Acjohtin instead sits in the ears and uses silicone tips.
• Best for calls → Acjohtin Earbuds. Four built-in microphones with ENC noise reduction are specified for calls. HIFI WALKER’s supplied details do not list a microphone feature.
• Best for phone-free music → HIFI WALKER Bone Conduction Headphones. Its 32GB of built-in storage supports MP3 playback, so listening does not depend on a phone or Bluetooth connection.
• Best for a secure in-ear fit during movement → Acjohtin Earbuds. Flexible ear hooks and three tip sizes provide options for adjusting the fit. HIFI WALKER uses an adjustable tension band instead.
• Best for a headset for Switch → Neither is confirmed as Switch-specific. HIFI WALKER lists Bluetooth 5.3 and Acjohtin lists Bluetooth 6.1, but those details do not confirm pairing with the console or performance in that setup. Check the Switch’s supported audio options before choosing.
• Best match for someone searching for open ear earbuds for Switch → HIFI WALKER is closer in design. It is an open-ear bone-conduction headset, not an in-ear earbud. Acjohtin is in-ear, and neither product’s supplied details establish dedicated Switch support.
The biggest practical distinction is not Bluetooth version. It is where the audio sits and what each product is built to handle. HIFI WALKER leaves the ear canals uncovered and adds MP3 storage for swimming. Acjohtin puts the earbuds in the ears, adds hooks for a secure fit, and relies on its case for extended combined playback. Those differences point to different routines: one is unusually suited to pool use, while the other is shaped around everyday listening, workouts, and calls.
There is also a difference in what “waterproof” means for the decision. HIFI WALKER’s IPX8 rating is paired with an explicit immersion detail and a swimming mode. Acjohtin is described as IPX7 and intended for sweat, splashes, and light rain. Those descriptions do not make the two interchangeable for a swim. If regular pool use is part of the plan, HIFI WALKER is the better-supported choice; if water exposure means perspiration or a shower of rain during a run, Acjohtin’s stated use is more relevant.
My Verdict
I would choose HIFI WALKER if swimming, open-ear listening, or phone-free music is the priority. Its IPX8 rating and 32GB MP3 storage give it a specific role that Acjohtin does not share. For a Switch, I would verify Bluetooth compatibility rather than assume either headset is guaranteed to pair. My pick for a swim-centered routine that includes Switch is HIFI WALKER; for longer case-supported playback and calls, I would choose Acjohtin.
