If you want familiar in-ear earbuds for quick listening, calls, and one-button controls, choose Generic Earbuds; if you need open-ear listening, longer stated battery life, or onboard music for swimming, choose Roujune Bone Conduction Headphones. For study, I’d lean toward Roujune when staying aware of your surroundings matters, and Generic when you prefer an in-ear fit and noise-control features.
• Generic Earbuds’ biggest strength: A compact in-ear design with Bluetooth 5.3, active noise cancellation, touch controls, and a charging case. Trade-off: The stated battery life is 3.5 hours per charge.
• Roujune Bone Conduction Headphones’ biggest strength: An open-ear bone-conduction design, up to 8 hours of stated battery life, and 32GB of memory for MP3 playback. Trade-off: They offer no noise control, and Bluetooth does not work underwater.
• Choose Generic Earbuds if you want conventional in-ear listening, call and music controls, and a case that displays charging status.
• Choose Roujune if you want your ears left open, need stored music for swimming, or prefer a longer stated listening window between charges.
Generic Earbuds are the more familiar choice: small in-ear earpieces that connect wirelessly over Bluetooth 5.3. Their listed features include automatic pairing after power-on, touch controls, and active noise cancellation. That combination makes them a plausible fit for someone who wants a straightforward pair for music, calls, and focused listening without moving to a specialized headphone style.
For studying, the in-ear fit and noise-control feature may suit a desk, library, or shared room where reducing some surrounding sound is useful. The product information also lists a 20 Hz–20,000 Hz frequency range and a 105 dB sensitivity figure. Those numbers describe audio specifications, but they don’t establish how good a particular recording will sound or how effectively noise is reduced. I’d treat the noise-control feature as a reason to consider these, not as a promise of complete quiet.
Battery life is the clearest limitation in the supplied specifications: each earbud is listed for 3.5 hours of audio at 100% volume. The charging case has a stated 200mAh capacity, and its LED indicator is intended to show the charging status of the earbuds and case. That offers a visible charging check, but the provided information does not say how many full recharges the case supplies. The earbuds are also described as suitable for rain and sweat, with an IPX4 waterproof rating in the product title; that is a different use case from swimming.

Who should skip them: Skip Generic Earbuds if you need open-ear listening, onboard music playback underwater, or a longer stated listening period before recharging.
Roujune takes a different approach. These are open-ear bone-conduction headphones rather than conventional in-ear earbuds. Their open-ear placement is the main design distinction: they do not use the same in-ear earpiece style as Generic. If you want to listen while remaining more aware of nearby sounds, that design may be a better match than earbuds intended to sit in the ear.
The feature set also points to longer sessions and swimming. Roujune lists up to 8 hours of battery life, Bluetooth connectivity, and 32GB of built-in memory for MP3 mode. The supplied instructions explain an important limitation: Bluetooth signals cannot transmit underwater, so swimming requires music stored on the headphones and playback switched to MP3 mode before entering the water. MP3 mode is therefore not just an extra option; it changes how you need to prepare for a swim.
The headphones are listed as IPX8 waterproof, use a bone-conduction driver, and have no noise control. That makes them specialized rather than all-purpose. For study, the open-ear design can make sense in a place where hearing the room is part of the goal, but it is less suited to blocking distractions. The product information gives a 20 Hz–20,000 Hz frequency range, but that figure alone does not tell you how the headphones will sound with every type of music or spoken audio.
Who should skip them: Skip Roujune if you want noise cancellation or other noise control, or if you expect Bluetooth streaming to work underwater.
• Best for in-ear listening → Generic Earbuds. Their listed earpiece shape and placement are both in-ear; Roujune is explicitly open-ear.
• Best for keeping your ears open → Roujune. Its open-ear bone-conduction design is the defining difference for people who want to remain more aware of their surroundings.
• Best for the longer stated battery life → Roujune. The listed figures are up to 8 hours for Roujune and 3.5 hours of audio at 100% volume for Generic.
• Best for study in a distracting room → Generic Earbuds, on paper. They list active noise cancellation; Roujune lists no noise control. The provided specifications do not quantify how much noise either design blocks.
• Best for swimming with stored music → Roujune. It has IPX8 waterproofing and 32GB of memory for MP3 playback. You must switch to MP3 mode because Bluetooth cannot transmit underwater.
• Best for quick calls and one-button operation → Generic Earbuds. Their listed controls include answering or rejecting calls, music navigation, and calling Siri. Roujune’s supplied details do not list equivalent call functions.
• Best for checking charging status → Generic Earbuds. Their case has an LED indicator for the charging status of the earbuds and case.
• Best for straightforward Bluetooth listening outside the water → Either, with different fits. Both offer wireless Bluetooth connectivity, but Generic is in-ear and Roujune is open-ear.
Buying Considerations
Start with the listening environment, not just the feature list. In a quiet room, either design could suit a study session if its fit and sound approach appeal to you. In a busier room, Generic’s listed active noise cancellation is a relevant advantage, while Roujune’s open-ear design and lack of noise control may leave more environmental sound present. The specifications don’t state how strong the cancellation is, so don’t assume it will eliminate every distraction.
Think about how long you listen before you can recharge. Generic’s stated 3.5 hours is specifically tied to audio at 100% volume, while Roujune lists 8 hours of average battery life. These figures are not presented under identical conditions, so they are useful as stated specifications rather than a controlled head-to-head result. Generic’s case adds a charging option, but its total recharge capacity is not specified.
Finally, separate ordinary Bluetooth use from swimming. Generic is described as suitable for rain and sweat, while Roujune is listed as IPX8 waterproof and includes MP3 storage. For swimming, Roujune’s instructions make the operating steps important: store compatible audio files on the headphones and select MP3 mode before entering the water. If you are shopping by a phrase such as “best over ear headphones for study,” note that neither product is described as over-ear. Shoppers looking for the “best open ear earbuds for study” are closer to Roujune’s design, while “best clip on earbuds for study” does not precisely describe either product based on the supplied information.
I would choose Roujune Bone Conduction Headphones for study if my priority were open-ear listening and a longer stated battery life. Its 32GB of storage and MP3 mode also give it a clear role for swimming, with the caveat that Bluetooth won’t work underwater.
I’d choose Generic Earbuds instead for an in-ear fit, listed active noise cancellation, and direct call controls.
For my own study-focused pick, I’d take Roujune when awareness of the room matters more than blocking distractions.
