If you want superior sound depth and a customizable audio experience for your outdoor adventures, choose LOBKIN Bone Conduction &; if you need a more affordable entry point with a dedicated app for personalization, choose PSIER Bone Conduction Swimming.
• LOBKIN Bone Conduction &: Offers the latest Bluetooth 6.1 connectivity and a hybrid driver system that prioritizes deep bass and clear treble, but requires manual button presses for control which some may find less intuitive than touch.
• PSIER Bone Conduction Swimming: Features an exclusive AI-driven app to tailor your sound profile and uses sleek touch controls, yet offers slightly shorter battery life and older Bluetooth 6.0 technology compared to its rival.
• Best for: The cyclist or swimmer who demands top-tier audio fidelity and long-term durability without needing smartphone pairing during their workout.
• Best for: The user who values modern touch interface convenience and wants to tweak their audio settings via a mobile application before hitting the water.
The LOBKIN X39 model is engineered for those who refuse to compromise on audio clarity while maintaining situational awareness. Its standout feature is the dual hybrid drive system, which fuses bone conduction vibrations with air conduction transmission. This isn't just a marketing buzzword; it translates to a tangible difference in how music sounds. While standard bone conduction headphones often struggle with bass response, leaving audio sounding thin, this unit delivers deeper bass and clearer treble by utilizing both methods simultaneously. For anyone using these as headband headphones for cycling, this means you get the safety of open ears without losing the richness of your playlist.
Durability is another pillar of this design. With an IP68 waterproof rating, these headphones are built to withstand the rigors of serious aquatic sports. They feature a triple-sealed structure that allows them to be submerged beyond 1.5 meters, making them ideal for swimmers who need gear that can handle chlorine, saltwater, and intense sweat without failing. The inclusion of 32GB of onboard storage is equally critical for this demographic. You can load up to 8,000 songs directly onto the device, meaning you can leave your phone behind entirely. Whether you are swimming laps or riding a long trail, you have your entire library available instantly without relying on a Bluetooth connection underwater, where wireless signals simply do not work.

Comfort is handled through skin-friendly liquid silicone materials, resulting in a weight of just 25 grams. This lightweight construction ensures they fit snugly even when worn under a swimming cap, goggles, or a bike helmet. The package includes a silicone neck strap, adding an extra layer of security so you never have to worry about the headphones slipping off during vigorous movement. However, there is a trade-off: the control scheme relies on physical push buttons rather than touch sensors. While this ensures you can operate them easily with wet hands or thick gloves, it might feel less seamless to users accustomed to tapping earbuds to change tracks. If you prioritize robust, button-based reliability over touch sensitivity, this is your pick.
PSIER positions itself as the choice for users who want a blend of performance and modern digital integration. Their X34-C model also utilizes a dual-driver system combining bone and air conduction, claiming to deliver 30% more bass than single-driver competitors. This makes them a strong contender for athletes looking for a richer sound signature without sacrificing the open-ear safety needed for road running or cycling. The key differentiator here is the software ecosystem. Unlike many competitors that offer a static listening experience, PSIER provides an exclusive AI-driven Boean app. This allows you to create unique soundscapes and tailor audio profiles to your specific preferences. If you enjoy tweaking your EQ to match the acoustics of a gym, a pool, or a windy trail, this customization capability is a significant draw.
In terms of usability, PSIER opts for a touch control interface. This offers a sleek, modern feel where a simple tap or swipe changes tracks or answers calls. For users who prefer the fluidity of touch interactions, this can be a game-changer compared to pressing small physical buttons. The headphones are coated in seamless liquid silicone, ensuring a soft fit that stays put during workouts. They are designed to integrate well with swim caps, goggles, sunglasses, and bike helmets, much like their competitor. The waterproofing meets the IPX8 standard, allowing submersion up to two meters deep for one hour. This certification confirms they are ready for rigorous underwater sessions, provided you switch to MP3 mode since Bluetooth does not function beneath the surface.
However, the battery life presents a notable trade-off. While the LOBKIN model promises up to 10 hours of continuous playback, the PSIER unit offers 8 hours. For most casual users, eight hours is sufficient, but for ultra-endurance athletes or those taking long multi-day camping trips where charging is difficult, the extra two hours provided by the competition could be the deciding factor. Additionally, the connectivity runs on Bluetooth 6.0. While still excellent and offering low latency, it is technically one generation behind the Bluetooth 6.1 found in the LOBKIN unit. For the average consumer, the difference in range and speed might be negligible, but tech-savvy users who demand the absolute latest wireless standards will notice the distinction.
• Best for battery longevity → LOBKIN Bone Conduction & (10 hours vs 8 hours).
• Best for audio customization → PSIER Bone Conduction Swimming (Exclusive AI Boean app for tailored sound profiles).
• Best for cutting-edge connectivity → LOBKIN Bone Conduction & (Bluetooth 6.1 offers potentially lower latency and better stability than Bluetooth 6.0).
• Best for underwater submersion depth → PSIER Bone Conduction Swimming (Certified for 2 meters vs 1.5 meters for LOBKIN).
• Best for tactile reliability → LOBKIN Bone Conduction & (Physical push buttons are easier to use with wet hands or gloves than touch controls).
• Best for sound customization → PSIER Bone Conduction Swimming (AI-driven tuning vs fixed hybrid drivers).
• Best for overall weight → LOBKIN Bone Conduction & (25 grams, slightly lighter than the PSIER equivalent).
• Best value for tech enthusiasts → PSIER Bone Conduction Swimming (App integration adds a layer of utility missing from the other option).
After weighing the specifications and considering the needs of a serious athlete, I would personally buy the LOBKIN Bone Conduction &. The combination of Bluetooth 6.1, a longer 10-hour battery life, and the physical button controls creates a more reliable tool for high-intensity activities. While the PSIER app is a nice touch, the core functionality of the LOBKIN—specifically its ability to last longer on a charge and connect more robustly—feels more essential for someone using best with microphone true wireless earbuds for cycling or swimming. The extra two hours of playtime and the latest wireless standard provide a margin of safety that I value highly. For my next ride, I am choosing the LOBKIN to ensure I never run out of power or lose connection mid-trail.
Yes, both models meet high waterproof standards. The LOBKIN holds an IP68 rating capable of submersion beyond 1.5 meters, while the PSIER is rated IPX8 for up to 2 meters deep for one hour. Both require switching to MP3 mode when fully underwater because Bluetooth signals cannot travel through water.
Absolutely, if you plan to swim or cycle without carrying your phone. Both devices store up to 8,000 songs internally, allowing for phone-free listening. This is crucial for underwater use where Bluetooth fails, ensuring you can still enjoy your music without dragging a phone into the pool or risking damage on the trail.
Touch controls generally work well, but physical buttons like those on the LOBKIN are often more reliable when hands are wet or covered in gloves. If you frequently train in heavy rain or wear thick winter gear, the button controls might offer a more consistent user experience.
With 10 hours of playtime, the LOBKIN covers a full day of varied training, including long swims and extended bike rides, without needing a recharge. The PSIER's 8 hours is still impressive and handles most standard workouts, but the LOBKIN provides a safer buffer for endurance events or back-to-back sessions.
