If you want open-ear headphones for movies and everyday listening, choose MONODEAL Bone Conduction Headphones; if you need a swimming-focused option with longer listed playback, choose LOBKIN Bone Conduction Swimming. The key difference is not Bluetooth generation or onboard storage: both list Bluetooth 5.4 and 32GB memory. It is the use case, with LOBKIN specifying 10 hours of playback and MONODEAL listing 8. Both require MP3 mode underwater.
MONODEAL Bone Conduction Headphones vs LOBKIN Bone Conduction Swimming at a Glance
• MONODEAL’s strength: An open-ear design, Bluetooth 5.4, and built-in 32GB MP3 storage in a 29-gram headset. Trade-off: Its listed battery life is 8 hours, shorter than LOBKIN’s.
• LOBKIN’s strength: IP68 waterproofing, 32GB storage, and 10 hours of listed playback. Trade-off: Bluetooth still cannot transmit underwater, and swimming requires MP3 mode.
• MONODEAL suits: People who want one headset for Bluetooth listening, calls, exercise, and stored audio for swimming.
• LOBKIN suits: Swimmers and active listeners who put a premium on longer listed playback and a secure-fit design.
• For movies: MONODEAL is my more straightforward pick for open-ear listening outside the water; neither sheet specifies a dedicated movie mode or noise cancellation.
MONODEAL combines bone conduction with an open-ear fit, so it does not sit inside the ear canal. That design is relevant if you dislike conventional in-ear earbuds or want to keep your ears open to ambient sounds while listening. At 29 grams, it is also light on paper, which makes it a reasonable option to consider for daily wear, cycling, running, or a movie watched on a compatible Bluetooth device.

MONODEAL lists an 8-hour battery life and a 2-hour charge time. That is enough on paper for many shorter listening sessions, but it gives less stated playback time than LOBKIN. Who should skip it: Anyone who needs more than 8 hours of listed playback between charges, or expects to stream Bluetooth audio while underwater.
LOBKIN is also an open-ear bone-conduction headset, but its details lean more explicitly toward swimming and exercise. Its IP68 rating and 32GB of onboard memory are useful together: you can load audio onto the headset, switch to MP3 mode, and listen underwater without relying on a phone connection. The product information describes use at depths of 10 feet for more than two hours. As with MONODEAL, Bluetooth is not the underwater listening option.
LOBKIN lists 10 hours of playback from a 2-hour magnetic charging session. That extra stated time may suit someone who wants longer sessions or plans to use the headset across several activities before charging. It weighs 29 grams and has a flexible titanium-alloy frame, a soft coating, and a hook-shaped design. The listed package also includes a pair of earplugs, though the central listening design remains open-ear bone conduction.
For land use, Bluetooth 5.4 supports pairing, while the built-in noise-canceling microphone is described as a feature for calls in noisy surroundings. The specifications do not list noise cancellation for listening, so I would not treat it as a way to block out a busy room during a movie. Who should skip it: Anyone looking for underwater Bluetooth streaming, or a headset whose main purpose is to isolate them from surrounding sound.
Side-by-Side: Which Should You Choose?
• Best for longer listed playback → LOBKIN Bone Conduction Swimming. It lists 10 hours; MONODEAL lists 8. Both list a 2-hour charge time.
• Best for a mixed Bluetooth-and-MP3 routine → MONODEAL Bone Conduction Headphones. It offers Bluetooth 5.4 for compatible devices and 32GB of storage for listening without a phone.
• Best fit for swimming without a phone → Either, with MP3 mode. Both have IP68 waterproofing and 32GB storage; Bluetooth transmission does not work underwater.
• Best for open-ear awareness during land activities → Either. Both use an open-ear bone-conduction design, rather than sealing the ear canal.
• Best for calls as well as listening → Compare the call details. MONODEAL lists a built-in microphone, while LOBKIN specifically describes a noise-canceling microphone.
• Best open ear earbuds for movies → MONODEAL, for straightforward Bluetooth use with a compatible phone, laptop, or tablet. Neither product sheet identifies a movie-specific feature or promises sound isolation.
• Best sweatproof Bluetooth headset for movies → Neither is specifically described as sweatproof. Both are listed as IP68 waterproof, but I would not turn that into an unsupported claim about every kind of moisture exposure or movie setup.
First, decide whether your regular listening happens in or out of the water. For swimming, the key practical requirement is having the audio stored locally: both products provide 32GB of memory, and both specify MP3 mode underwater because Bluetooth signals cannot transmit through water. If you want to play a movie or other audio over Bluetooth on land, pair the headset with a compatible device instead.
Next, consider how you prefer a headset to sit. Both are open-ear bone-conduction models, but LOBKIN lists a hook-shaped design and flexible frame, while MONODEAL describes its open-ear fit and 29-gram weight. The sheets do not establish that one will fit every person better, so those design details are more useful as points to compare than as guarantees.
Battery life is the clearest numerical separator: 8 hours listed for MONODEAL and 10 for LOBKIN, with a 2-hour charge time for each. Neither figure tells you exactly how long you will get in every listening situation, but the difference can help if you expect longer sessions. For current pricing, check the page’s Amazon button rather than assuming one model costs less.
My Verdict
No. Both product sheets say Bluetooth cannot transmit underwater. Load audio into the built-in 32GB memory and switch to MP3 mode for swimming.
LOBKIN lists 10 hours of playback, compared with 8 hours for MONODEAL. Both list a 2-hour charging time.
They may suit someone who wants an open-ear design and Bluetooth pairing with a compatible device. The product information does not specify a movie mode, so check that the headset fits your device and listening setup.
Neither is listed with noise-control functionality for listening. Both use an open-ear design, which keeps the ears open rather than sealing them; LOBKIN’s noise-canceling microphone is described for calls, not for blocking noise during playback.
