If you want a pair that keeps playing when you get in the pool and can hold your whole music library offline so your phone stays out of the room during a long study session, choose RELAXYO Bone Conduction Swimming; if you need an uncomplicated open-ear pair for study, workouts and commutes — one with a hard carry case in the box and a battery that stretches across a full day of classes — choose Generic Bone Conduction Headphones. That's the short answer. The longer answer is about how each one is built and what that means for the way you'll actually use it.
• RELAXYO's biggest strength: IP68 waterproofing plus 32GB of built-in storage, so it works underwater and away from your phone entirely.
• RELAXYO's biggest trade-off: It's a bare-bones kit — bone conduction with no noise control, adult sizing only, and no carry case listed.
• Generic's biggest strength: 8 hours of playback, a flexible titanium open-ear frame, and an EVA case with a hook included.
• Generic's biggest trade-off: It's water-resistant and sweatproof, not waterproof — and the listed charging time is long, so you have to plan ahead.
• Choose RELAXYO if you want one pair for swimming, running and phone-free study.
• Choose Generic if you want a simple, comfortable open-ear set for study sessions, gym work and walking, with somewhere solid to store it.
RELAXYO's pitch is narrow and honest: a bone conduction headset you can take into the water and use without a phone. The IP68 rating is the headline, and it's backed by practical detail — the frame is thin enough to sit under a swim cap or pair with goggles, and the controls are three physical buttons you can find by feel. The important caveat is that Bluetooth doesn't travel through water, so underwater listening runs off the internal player. You double-press the power button to switch between Bluetooth and MP3 mode, and that's the mode you want the moment you put your face in the pool.

The 32GB of storage is the part that matters most for study. That's room for roughly 7,000 songs, loaded by plugging the magnetic charging cable into a computer and dragging files across. This is worth thinking about: an offline player means no phone on the desk, no notifications, no "just checking something" spiral in the middle of a revision block. For anyone who has ever tried to concentrate with a phone face-up beside them, an open-ear pair that plays downloaded lecture audio or a study playlist straight from its own memory is a genuinely useful tool. Battery is 7 hours of music from a 1.5-hour charge, and Bluetooth 5.4 holds a connection at around ten meters in open space.
Where it gives ground: there's no noise control of any kind on this headset, so open-ear means the room comes in with the music — fine in a quiet bedroom, less fine next to a chattering café. It's listed for adults, the colour is beige, and there's no case in the box. If you want active noise cancelling to wall out a noisy library, this isn't that product, and neither is the Generic.
The Generic set is the friendlier all-rounder of the two. It uses the same bone conduction driver approach with a 20 Hz–20,000 Hz range, wrapped in a lightweight titanium frame that bends and holds its shape. The earpieces are oval and sit open-ear, which means you keep your surroundings audible while you listen — the classic bone conduction argument, and a real one if you study while walking or take calls on the way to class.
Two practical details stand out. First, it's rated at 8 hours of music playback, which is a touch more than RELAXYO's 7, and enough to cover a full day without topping up. Second, it ships with an EVA case and a hook, which sounds trivial until you've had a pair of open-ear headphones rattling loose in a backpack. There's also a stated age range of adult and teen, which matters if you're searching for the best kids headphones for study for a teenager who needs to hear a parent or a doorbell while working.
The honest trade-offs: the body is described as sweatproof and water-resistant using hydrophobic materials, but there's no IP rating listed and it's not built for swimming — sweat and light rain, yes; laps, no. And despite "quick charging" in the product name, the listed charge time is 8 hours, which is slow by any standard. Treat this as an overnight charger. Charging is over USB, which is convenient, but you'll want a routine rather than a habit of plugging it in five minutes before you leave.
• Best for swimming and water sports → RELAXYO Bone Conduction Swimming. IP68 and an internal player exist for exactly this; the Generic set is water-resistant only.
• Best for phone-free focus while studying → RELAXYO. Load your study playlist or downloaded lectures into 32GB and leave the phone in another room.
• Best for a full day away from a charger → Generic Bone Conduction Headphones. 8 hours of playback against RELAXYO's 7, which is a small but real edge.
• Best for quick top-ups between lectures → RELAXYO. A 1.5-hour charge versus an 8-hour one is not a close contest.
• Best for all-weather outdoor use → RELAXYO. Rain and heavy sweat are covered by the IP68 rating; the Generic set is splash-and-sweat resistant.
• Best for keeping the kit intact in a bag → Generic. The included EVA case and hook are a real practical advantage for students moving between rooms all day.
• Best for teens sharing a study space → Generic. It's listed for adults and teens, while RELAXYO is listed for adults.
• Best for a genuinely quiet study environment → neither. Both list no noise control, so if you need silence you'll be pairing these with earplugs, not replacing them.
If you're comparing open ear earbuds for study and haven't used bone conduction before, expect a thinner, more ambient sound than sealed earbuds. That's the design working as intended, not a fault — but it's the reason these are better suited to a desk, a run or a bike than to a crowded train.
My Verdict
Both. The IP68 body and MP3 mode are built for water, but the same MP3 mode is what makes it useful at a desk — 32GB of downloaded audio, no phone, no notifications. Just charge it before an exam-week marathon; you get 7 hours per charge.
No. They're described as sweatproof and water-resistant, and no IP rating is listed. Sweat, light rain and gym humidity are within their comfort zone; a pool is not.
The Generic set lists 8 hours of playback with an 8-hour charge time. RELAXYO lists 7 hours of playback from a 1.5-hour charge. The Generic wins slightly on runtime; RELAXYO wins comfortably on how fast you can refill it.
For a teen, I'd lean Generic, simply because its listed age range covers adult and teen while RELAXYO's is adult. Neither has noise cancelling, so a quiet room still does most of the work.
