If you want bone-conduction headphones for swimming and a simple MP3-first setup for kids with microphone, choose MARLALL Bone Conduction Swimming; if you need longer battery life, stated Bluetooth 6.0, and microphone noise cancellation, choose Flemikie Bone Conduction Headphones.
MARLALL Bone Conduction Swimming vs Flemikie Bone Conduction Headphones at a Glance
• MARLALL’s strength: IPX8 waterproofing, 32GB of built-in storage, an ear-hook design, and up to 7 hours of playback. Trade-off: Bluetooth does not work underwater, and the listed playback time is shorter than Flemikie’s.
• Flemikie’s strength: IPX8 waterproofing, 32GB of storage, Bluetooth 6.0, dual microphones with AI noise cancellation, and up to 8 hours of playback. Trade-off: Swimming still requires MP3 mode, and full recharge takes about 2 hours.
• Choose MARLALL if your priority is a simple swimming-focused option with open-ear listening and a secure ear-hook design.
• Choose Flemikie if you want more listed call and connectivity features for swimming, workouts, and outdoor use.
MARLALL is a swimming-focused choice for someone who wants open-ear listening, local music storage, and a fit designed to stay put during activity. Its IPX8 rating is intended for water use, while the built-in 32GB MP3 player lets you listen underwater without relying on a phone connection. The key limitation is clear: Bluetooth mode is not supported underwater, so swimming means switching to MP3 mode.
The ear-hook design is intended to distribute pressure and help keep the headphones secure during swimming and other workouts. The product information also describes a soft silicone overmold and a lightweight feel. For everyday use away from the pool, open ears can help you remain aware of nearby sounds while running or hiking.

Flemikie combines an IPX8 rating with a 32GB MP3 player, so it can handle a similar basic swim routine: store audio on the headphones, switch to MP3 mode, and leave the phone out of the water. Its product information specifies submersion up to 2 meters for 2 hours. Bluetooth 6.0 is intended for use outside the water, with a stated range of 10 meters.
The extra features make Flemikie the more versatile-looking option on paper. It lists dual microphones with AI noise cancellation, up to 8 hours of playback, and a magnetic charging port that takes about 2 hours to recharge. The open-ear design and adjustable headband are meant to provide a secure fit while leaving the ear canals open. That combination may suit someone moving between pool sessions, cycling, running, and calls.
Choose Flemikie if those microphone and Bluetooth details matter to you, or if you want the longer stated battery life. Skip it if your needs are limited to basic swimming playback and you would rather keep the decision focused on an ear-hook design and MP3 listening. Its swimming limitation is the same as MARLALL’s: Bluetooth does not work underwater.
• Best for swimming without a phone → Tie. Both list IPX8 waterproofing and built-in 32GB storage, and both require MP3 mode underwater.
• Best for longer stated playback → Flemikie. It lists up to 8 hours; MARLALL lists up to 7 hours.
• Best for stated Bluetooth version and range → Flemikie. Its information specifies Bluetooth 6.0 and a 10-meter range. MARLALL’s sheet lists Bluetooth but gives no version or range.
• Best for listed microphone features → Flemikie. It specifies dual microphones with AI noise cancellation. MARLALL advises drying its microphone after swimming but does not list comparable call-processing features.
• Best for an ear-hook design → MARLALL. Its design is described as an ergonomic ear hook intended to distribute pressure and stay secure during activity.
• Best for an adjustable headband → Flemikie. Its product details describe an adjustable headband and soft silicone pads.
• Best for open-ear awareness outdoors → Both. Each uses an open-ear bone-conduction design intended to leave the ears open to surrounding sounds.
• Best for a swim-first routine with fewer listed extras → MARLALL; best for mixed workouts and calls → Flemikie. The fit and usage details point in different directions, so match the design to your routine.
This isn’t a choice between Bluetooth swimming and MP3 swimming. Both require offline audio in the water. The practical distinction is whether you want MARLALL’s ear-hook approach or Flemikie’s longer listed battery life and more detailed microphone and Bluetooth specifications.
For “headband headphones for college students,” Flemikie’s Bluetooth and microphone details may sound useful for moving between calls and workouts, while its MP3 mode supports swimming without a phone. MARLALL could fit a student whose main goal is pool listening. Neither sheet establishes how either model performs in lectures or study settings, so I’d choose based on the listed features rather than assume classroom suitability.
My Verdict
I’d choose Flemikie Bone Conduction Headphones for the broader mix of swimming, outdoor workouts, and calls. Its listed 8-hour playback, Bluetooth 6.0, and dual microphones with AI noise cancellation give it a more complete feature set on paper, while still offering 32GB storage for MP3 swimming.
For kids with microphone, I’d compare the fit and call features carefully rather than assume either adult-described model is designed specifically for children. MARLALL remains a sensible alternative if the ear-hook design and a simpler swim-first setup matter more to you.
No. Both product sheets specify that Bluetooth does not work underwater. For swimming, use the built-in MP3 player with music stored on the headphones.
Flemikie lists up to 8 hours of continuous playback, compared with up to 7 hours for MARLALL. Actual listening time can vary, but the listed figures give Flemikie the advantage on battery life.
Flemikie lists dual microphones with AI noise cancellation. MARLALL has a microphone, but its instructions say to dry it after swimming to help prevent call issues; the provided information does not specify comparable noise-cancellation features.
Either can support MP3 listening underwater, and both list IPX8 waterproofing. I’d choose MARLALL for its ear-hook design; I’d choose Flemikie if you also want its longer listed playback time and more detailed Bluetooth and microphone features.
