If you want open-ear sports headphones for school, choose Amazon Renewed SHOKZ OpenRun; if you need bone conduction headphones for swimming, choose PSIER Bone Conduction Swimming. The deciding difference is straightforward: OpenRun is built around workout-friendly listening and quick charging, while PSIER adds onboard music storage and a swimming-ready waterproof design.
• Amazon Renewed SHOKZ OpenRun’s strength: A lightweight, open-ear fit, eight hours of listening, and a 10-minute quick charge that can provide up to 1.5 hours of battery life. Trade-off: It is not suitable for swimming.
• PSIER Bone Conduction Swimming’s strength: IPX8 waterproofing and 32GB of onboard storage for listening in MP3 mode underwater. Trade-off: Bluetooth cannot connect underwater, so you need to switch to MP3 mode for swimming.
• For calls and everyday workouts: OpenRun is the more direct fit, with eight hours of music, calls, and podcasts.
• For swimming and phone-free listening: PSIER is the clear fit, with Bluetooth and stored music modes.
• Choose OpenRun for a simple open-ear workout option; choose PSIER if swimming or built-in music storage is essential.
OpenRun is the more straightforward choice for someone who wants open-ear audio for workouts, runs, or a school day with movement between activities. Its wraparound frame sits outside the ears, leaving them open to surrounding sounds. The listed weight is 26 grams, and the design uses Bluetooth rather than a wired headphone jack.
The battery is rated for eight hours of music, calls, and podcasts. A 10-minute quick charge can provide up to 1.5 hours of battery life, which is useful when there is not much time to recharge before heading out. Its IP67 rating covers sweat and water exposure during exercise, but the product is explicitly not suitable for swimming.

PSIER Bone Conduction Swimming: Who It's For
PSIER is designed for a different kind of use. It combines bone and air conduction drivers, and its key practical distinction is that it can play stored music in MP3 mode. The built-in 32GB memory is described as holding up to 8,000 songs, allowing phone-free listening in and out of the water. It also supports Bluetooth 6.0 for listening when a Bluetooth connection is available.
For swimming, PSIER carries an IPX8 rating and is specified for submersion up to two meters for one hour. The important catch is that Bluetooth cannot connect underwater: you need to switch to MP3 mode. The listed battery life is eight hours, and a full charge takes two hours through magnetic charging.
I would look at PSIER if swimming is a regular activity or if I wanted music stored directly on the headphones for phone-free workouts. Its open-ear design is described as compatible with swim caps, goggles, sunglasses, and bike helmets. If quick charging is a priority, though, OpenRun has the more specific convenience claim: a 10-minute charge can provide up to 1.5 hours of use, while PSIER lists two hours for a full charge.

• Best for someone who wants a simple workout-focused option → Amazon Renewed SHOKZ OpenRun. Its listed strengths center on open-ear listening, workout use, and sweat and water resistance.

The products overlap in some important ways. Both have open-ear designs and list eight hours of listening time. But “eight hours” does not make them interchangeable. OpenRun’s standout charging detail and call-focused description suit a workout routine where a phone connection matters. PSIER’s built-in storage and underwater MP3 mode solve the separate problem of listening while swimming.
The word “earbuds” can also be misleading here. Neither product is described as a conventional in-ear design. Both are open-ear headphones, with different ways of delivering sound and different intended strengths. If your search is for the best clip on earbuds for school, compare the actual fit and routine you need: OpenRun has a wraparound frame, while PSIER’s stated case is its adaptable fit for sports gear and water use.
My Verdict
In my opinion, I would choose Amazon Renewed SHOKZ OpenRun for school if swimming is not part of the plan.
Its 26-gram weight, open-ear design, eight-hour listening time, and quick-charge feature make a focused case for everyday workouts and movement.
I would choose PSIER instead if I needed swimming support or onboard music for phone-free listening.
For school use beyond the pool, OpenRun is my pick; for water, PSIER’s specific features change the answer.
No. OpenRun is described as sweat- and waterproof for workouts, fitness, and running, but it is not suitable for swimming. If you need headphones designed for submersion, PSIER is the relevant option.
Can PSIER Bone Conduction Swimming use Bluetooth underwater?
Both list eight hours of listening. OpenRun specifically includes music, calls, and podcasts, while PSIER lists eight hours of playtime. Their charging details differ: OpenRun lists a 10-minute quick charge for up to 1.5 hours of battery life; PSIER lists a two-hour full charge.
For school-related workouts and everyday movement, I would lean toward OpenRun for its 26-gram wraparound design and quick-charge feature. If your school routine includes swimming and you want stored music that works underwater, PSIER is the more suitable choice. Check the current price on Amazon before deciding, since the right fit depends on your needs as well as the cost.
