If you want open-ear listening with offline playback for mobile gaming breaks and outdoor activity, choose Monster Open Ear BC300; if you need conventional Bluetooth earbuds with long case-supported playtime, choose Qecnato Earbuds. The key difference is how they fit and what they prioritize: Monster leaves the ears open and includes built-in MP3 storage, while Qecnato uses over-ear hooks, touch controls, and a charging case. For someone searching for cheap earbuds bulk, these are two very different styles to weigh rather than interchangeable picks.
Monster Open Ear BC300 vs Qecnato Earbuds at a Glance
• Qecnato Earbuds strength: Up to 75 hours of total playback when used with the charging case; trade-off: They sit over the ears and do not offer Monster’s built-in MP3 player.
• Monster suits buyers who want to hear their surroundings or listen without carrying a phone during a swim.
• Qecnato suits buyers who want a familiar earbud style with ear hooks, touch controls, and a case that extends listening time.
Monster Open Ear BC300 is an open-ear bone-conduction headphone with a flexible memory frame and soft silicone ear hooks. That design keeps the earpieces outside the ear canal, which may appeal to anyone who dislikes the plugged-in feel of conventional earbuds. It also leaves the ears unobstructed, so you can remain more aware of nearby sounds during an outdoor run or bike ride. The secure, adjustable frame is intended to stay put during active movement and work alongside swim caps, goggles, sunglasses, and bike helmets.
Its standout feature for swimming is the combination of IPX8 waterproofing and 32GB of built-in MP3 storage. Monster specifies that the headphones can be submerged up to two meters for up to two hours, with MP3 mode used underwater. Bluetooth cannot transmit reliably through water, so the built-in player is the practical choice for listening during a swim. For phone-free listening on land, too, the stored music can be transferred by USB. Bluetooth 6.0 is available for wireless streaming when you are not submerged.
Monster lists up to 10 hours of playback and a full charge in about two hours using the magnetic charging cable. That makes it a distinct option for swimmers, runners, or travelers who value open-ear comfort and offline listening more than a conventional sealed-earbud fit. It could also work for a buyer considering a lightweight kids headset for mobile gaming, provided the open-ear fit and adult age-range description suit the intended user. Skip it if you specifically want earbuds that seal in your ears or expect Bluetooth streaming to work underwater.

Qecnato takes the more conventional wireless-earbud route, with over-ear hooks made from soft silicone and included silicone earplugs in S, M, and L. The hooks are designed to help keep the earbuds secure during running, workouts, commutes, and other movement. Unlike Monster’s open-ear bone-conduction setup, Qecnato’s earbuds sit in the ears. The product information lists passive noise cancellation and sound isolation, so this design is better suited to listeners who want a more enclosed fit than an open-ear pair provides.
Battery life is the headline practical advantage. Qecnato specifies up to 15 hours from the earbuds on a charge and up to 75 hours total when the charging case is included. The case uses a USB-C port, takes about 1.5 hours to charge, and has a dual LED display showing its battery and the earbuds’ charging progress. Those details help make it easier to keep track of charging without relying on a phone display or guessing how much power remains.
Bluetooth 5.4 supports wireless listening and calls, while the earbuds are listed as compatible with smartphones, tablets, and computers using iOS, Android, or Windows. Four microphones and ENC noise-canceling technology are intended to help keep calls clearer when there is background noise. The 14.2mm dynamic drivers are specified alongside a 20 Hz–20,000 Hz frequency range. For workouts, IP7 protection is intended to guard against sweat and rain. Skip Qecnato if you need open-ear awareness, underwater MP3 playback, or a headphone that can be submerged for swimming.
• Best for underwater listening → Monster Open Ear BC300. Its IPX8 design and built-in 32GB MP3 storage support playback underwater; Bluetooth streaming does not.
• Best for longer total playback with a case → Qecnato Earbuds. The stated total is up to 75 hours with the case, compared with up to 10 hours for Monster on a charge.
• Best for hearing more of your surroundings → Monster Open Ear BC300. Its open-ear bone-conduction design does not plug the ear canal.
• Best for a more enclosed earbud fit → Qecnato Earbuds. They include silicone earplugs in three sizes and have over-ear hooks.
• Best for phone-free music during a swim → Monster Open Ear BC300. Its offline MP3 mode avoids relying on a Bluetooth connection underwater.
• Best for call-focused features → Qecnato Earbuds. The four-microphone array and ENC are intended to improve call clarity in noisy surroundings.
• Best for touch-based controls → Qecnato Earbuds. Touch controls support music functions, calls, volume, and voice assistant activation.
• Best for Bluetooth headphones for mobile gaming → Qecnato for a conventional earbud fit; Monster if open-ear comfort matters more. Neither spec sheet states a gaming-specific latency feature, so I would not choose either on a promise of reduced audio delay.
My Verdict
Before choosing, decide where you expect to use the headphones most. “Waterproof” does not mean the same thing for these two products: Monster’s stated IPX8 protection and underwater MP3 mode are relevant to swimming, while Qecnato’s IP7 protection is described for sweat and rain. If you want music while submerged, Monster’s offline player matters more than its Bluetooth version. If you only need a pair for rainy runs or gym sessions, Qecnato’s hooks and case-supported playtime may be the more relevant combination.
Think about fit as well as features. Monster’s open-ear bone-conduction design leaves the ear canal unblocked, while Qecnato includes earplugs in three sizes and uses an over-ear hook. Those differences can matter more than a spec sheet’s headline numbers if you already know you dislike a particular style. Consider whether you want to hear more of your surroundings or prefer a more enclosed earbud fit. The sheets do not provide a basis for claiming one design will fit every listener better.
For mobile gaming, neither product lists a dedicated low-latency mode or a gaming-specific connection feature. Both connect over Bluetooth, but the available specifications do not establish how closely game audio will stay synchronized with on-screen action. If that is your deciding factor, avoid assuming that a newer Bluetooth number alone guarantees a better gaming experience. For occasional play, choose based on the fit and controls you prefer; for gaming that depends on precise sound timing, look for explicit latency information before deciding.
Finally, match the battery figures to your routine. Monster lists up to 10 hours on a charge, along with magnetic charging and a roughly two-hour full charge. Qecnato lists up to 15 hours for the earbuds and up to 75 hours including its case, with a roughly 1.5-hour case charge. Those are stated maximums, not a promise that every listening pattern will produce the same runtime. If the current price affects your decision, check the current price on Amazon before choosing; I can’t make a price-based value comparison from the specifications alone.
FAQ
Both products support Bluetooth connections, but neither sheet specifies a gaming mode or latency figure. Qecnato has a conventional earbud fit; Monster is open-ear and also supports Bluetooth streaming when you are not underwater.
Qecnato specifies up to 15 hours per earbud charge and up to 75 hours with its case. Monster specifies up to 10 hours on a charge, with a full charge taking about two hours.
That depends on the current price and what features matter to you, so check the current price on Amazon rather than assuming one is the better deal. On features alone, Monster adds open-ear listening and offline MP3 storage; Qecnato offers a case, touch controls, and longer stated total playback.
