If you want open-ear headphones with swimming-ready waterproofing and built-in MP3 storage for remote work and workouts, choose FJX Bone Conduction Headphones; if you need open-ear earbuds with a charging case and up to 15 hours of combined playback, choose PAXA T26. For desk days that may turn into a run or swim, the FJX is the more versatile design; for everyday Bluetooth listening with a case, the PAXA is the more straightforward fit.
• FJX strength: IP68 waterproofing, open-ear bone conduction, and 32 GB of built-in MP3 storage. Trade-off: Bluetooth does not work underwater, and listed battery life is 4 hours.
• PAXA strength: A charging case extends playback to up to 15 hours, with touch controls and open-ear hooks. Trade-off: Its IPX4 water resistance is not swimming protection.
• FJX is for: People who want one headset for outdoor listening, swimming with local MP3 files, and Bluetooth use on land.
• PAXA is for: People who want open-ear earbuds for calls, office listening, and workouts, with a case for recharging between sessions.
The FJX stands out for the combination of open-ear bone conduction and built-in music storage. Rather than sitting inside the ear canal, its design rests around the ears and sends sound through vibrations. That leaves the ear canal open, which can help you remain aware of nearby sounds during a walk, run, or other outdoor activity. The listed weight is 29 grams, and the frame uses titanium, making it a lightweight option for people who prefer a band-style fit over separate earbuds.
Its clearest advantage is the way it handles swimming. The FJX has an IP68 rating and a local MP3 mode with 32 GB of storage. Because Bluetooth signals are affected underwater, swimming calls for saved music rather than a phone connection. That same onboard storage may be useful if you want to leave your phone behind for part of a workout. Bluetooth 5.3 is available for listening and calls on land, and the headset can pair with phones, tablets, computers, and laptops.

For remote work, I see the FJX as a better fit for someone who wants an open-ear headset for a walk between meetings, or who values one device that can also move into sports and swimming. The compromise is the listed 4-hour average battery life. That may be enough for shorter stretches, but it gives less room for a long workday than the PAXA’s case-supported playback. Skip the FJX if you specifically want conventional earbuds with a charging case or need Bluetooth audio while underwater.
The PAXA T26 uses over-ear hooks and open-ear earbuds, so it does not go into the ear canal. Its design aims to stay in place during movement while leaving you able to hear some of your surroundings. Bluetooth 5.3 connects it to phones and laptops, and the listed range is 10 meters. Touch controls handle audio playback and calls, which may suit someone who wants to make basic adjustments without reaching for a phone.
The strongest everyday-use point is its charging case. PAXA lists 5 hours of playback per charge and up to 15 hours with the case. That makes the T26 a practical candidate for a mix of remote-work calls, errands, and exercise, especially if you can return the earbuds to the case between listening sessions. The earbuds are IPX4 water-resistant, which suits sweat and moisture exposure, but that is a different use case from the FJX’s swimming-oriented IP68 rating.
For remote work, the PAXA is the more natural choice if you want lightweight, open-ear earbuds with a case to top them up during the day. Its directional sound is described as reducing leakage, a useful consideration in a shared space, though open-ear listening is still not the same as blocking outside noise. PAXA lists hybrid noise cancellation, but the data does not specify that this provides active noise cancellation for sports or isolates the listener from a busy room. If you need that kind of isolation, neither product’s open-ear design is an obvious match. And if swimming is part of the plan, the T26’s IPX4 protection is not the right feature for it.
• Best for swimming with stored music → FJX Bone Conduction Headphones. Its IP68 rating and 32 GB MP3 mode are the decisive combination. Use MP3 mode underwater; Bluetooth is not suited to underwater transmission.
• Best for charging between work and workout sessions → PAXA T26. Its case supports up to 15 hours of combined playback, compared with the FJX’s listed 4-hour average battery life.
• Best for remote work while staying aware of your surroundings → Either, with a different fit. Both have open-ear designs. Choose the FJX’s behind-the-ear bone-conduction frame if that style appeals; choose the PAXA’s ear hooks if you prefer separate earbuds.
• Best for a phone-free swim → FJX Bone Conduction Headphones. Its built-in storage lets you play local music without relying on a Bluetooth connection in the water.
• Best for sweat-prone workouts that do not include swimming → PAXA T26. It is described as resistant to sweat and moisture and carries an IPX4 rating.
• Best for longer stretches away from a charger → PAXA T26. The case brings total playback up to 15 hours, although each earbud charge is listed at 5 hours.
• Best for a longer-duration outdoor session with open ears → FJX Bone Conduction Headphones, if you can manage its shorter battery life. The open design supports awareness, but its 4-hour battery figure is a real limitation to weigh.
• Best if you want a headset rather than earbuds → FJX Bone Conduction Headphones. Its titanium frame sits around the ears; the PAXA is a hook-style earbud set.
I’d choose the FJX Bone Conduction Headphones if swimming and stored music are meaningful parts of my routine. IP68 protection and 32 GB of MP3 storage give it a use the PAXA cannot match.
For remote work, though, I’d pick the PAXA T26 if I wanted open-ear earbuds and more playback supported by a charging case. My overall choice is the FJX, because its swim-ready design and local music mode make it more versatile for the specific work-and-workout mix I’d want.
FAQ
No. The product information says water interferes with Bluetooth transmission. For swimming, use the built-in MP3 mode with music stored on the headset.
Its IPX4 rating is described for sweat and moisture, not swimming. If swimming protection is essential, the FJX’s IP68 rating and MP3 mode are the more relevant features.
The PAXA lists hybrid noise cancellation, but its open-ear design is intended to preserve awareness of the environment, and the available specifications do not establish that it provides active noise cancellation that blocks office sounds. The FJX lists no noise control. For someone who needs strong isolation, these open-ear options may not be the right category.
