If you want a cycling headphone that keeps your ears open to traffic while surviving sweat, rain and long rides on a single charge, choose LAMA Bone Conduction Headphones; if you need a lightweight open-ear headset for casual riding, walking and calls at a lower commitment, choose HZMFNWX Air Conduction Open-Ear.
• LAMA's biggest strength: a bone conduction driver paired with Bluetooth 5.4, up to 15 hours of playtime and an IP55 sweat/water rating — the most "sports-grade" spec sheet of the two.
• LAMA's biggest trade-off: it's a more specialised, feature-dense headphone, so it suits riders who want a dedicated training companion rather than a casual all-rounder.
• HZMFNWX's biggest strength: a simple, lightweight air conduction open-ear build with a wraparound fit and a built-in mic — easy to live with for music, meetings and everyday movement.
• HZMFNWX's biggest trade-off: the spec sheet is deliberately minimal (no battery figure, no IP rating, no Bluetooth version), so it's a "keep it simple" pick rather than a numbers-driven one.
• Who LAMA is for: cyclists, runners and commuters who ride in traffic and want environmental awareness plus weather resistance.
• Who HZMFNWX is for: casual riders, walkers and office users who want an open, breathable fit and one headset for both music and calls.
LAMA's whole pitch is safety plus stamina, and for a cyclist that combination matters more than almost anything else. Bone conduction drivers sit outside the ear canal and send sound through the cheekbone, so your ears stay completely open. On a bike that's the difference between hearing a car creep up behind you and being startled by it. The spec sheet frames this around urban running, early morning cycling and marathon training, and it's the same logic on two wheels: approaching traffic, sirens and pedestrian signals all stay audible while your playlist keeps going.
The hardware backs up the riding use case. Bluetooth 5.4 gives you fast pairing and a stable link out to around 33 feet, which is handy if you leave your phone in a jersey pocket or on a bench while you grab a drink. Battery life is rated up to 15 hours on a 2-hour charge with 144 hours of standby — realistically several rides between charges, and enough for a long weekend of training. The IP55 rating means dust and sweat resistance with a hydrophobic nano-coating against rain and dirt, so a drizzly commute or a sweaty climb isn't a problem.
HZMFNWX Air Conduction Open-Ear: Who It's For
HZMFNWX takes the opposite approach: keep it simple, keep it light, keep it open. This is an air conduction open-ear design, meaning the drivers sit near the ear rather than inside it, so surrounding sound still gets through while you listen. For cycling, that's the same core benefit as bone conduction — awareness — just delivered a different way. The wraparound fit is described as secure and pressure-reducing compared with traditional in-ear buds, which is the classic complaint open-ear designs are trying to solve: no swollen ear canals after an hour, no heat build-up.
The feature list is short and practical. Wireless Bluetooth pairing works with most phones, tablets and laptops. There's a built-in microphone for calls, meetings and talking on the move. And the use cases listed cover running, gym work, cycling, hiking, walking, driving, office work and home listening — it's positioned as one headset for everything rather than a dedicated sports tool. The open-ear structure is pitched at people who simply don't like things inserted into their ear canal, which is a real and common preference.
What the spec sheet doesn't give you is the detail set: no battery life figure, no IP rating, no Bluetooth version, no weight. That's not a flaw in the product, it's a limit of what's documented — but it does mean you're buying on design philosophy rather than numbers. Who should skip it? Riders who train in heavy rain, who need a verified battery figure before a long ride, or who want the most feature-dense option available. For everyone else — the commuter, the casual rider, the walker, the person taking calls between errands — the simplicity is the point, and the metal enclosure and white finish give it a clean, understated look.
Side-by-Side: Which Should You Choose?
• Best for cycling safety and awareness → LAMA Bone Conduction Headphones. Bone conduction leaves the ear canal fully open, which is exactly what you want in traffic.
• Best for sweat, rain and dust → LAMA Bone Conduction Headphones. The IP55 rating and hydrophobic nano-coating are the only weather-resistance claims between the two.
• Best for helmet and glasses wearers → LAMA Bone Conduction Headphones. The slim hook profile is specifically designed not to interfere with eyewear or helmets.
• Best for the lightest possible feel → LAMA Bone Conduction Headphones. At roughly 24 g with a flexible titanium frame, it's the only weight figure given.
• Best for simplicity and everyday all-round use → HZMFNWX Air Conduction Open-Ear. No spec overload, just open-ear sound, a mic and a secure wraparound fit.
• Best for music plus calls in one headset → HZMFNWX Air Conduction Open-Ear. The integrated microphone is a headline feature rather than an afterthought.
• Best for people who hate things in their ears → HZMFNWX Air Conduction Open-Ear. Air conduction sits near the ear, not inside it, and that's the whole design brief.
In my opinion, if cycling is genuinely your main use, buy the LAMA Bone Conduction Headphones. The combination of an open bone conduction driver, Bluetooth 5.4, up to 15 hours of battery and an IP55 rating is the more complete cycling package, and the helmet/glasses-friendly hook design tells me it was built with riders in mind. I'd pick the HZMFNWX Air Conduction Open-Ear if I wanted one light, simple open-ear headset for riding, walking, calls and desk work without thinking about specs at all. Both keep your ears open, which is the single most important thing on a bike.
can you bike with headphones
Yes, and open-ear designs are the sensible way to do it. Both the LAMA bone conduction and HZMFNWX air conduction models sit outside or near the ear canal rather than sealing it, so you can still hear traffic, horns and other riders while your music plays. That awareness is the whole reason these two designs exist for cycling.
how to bike with headphones
Keep the volume low enough that ambient sound still comes through, wear one headset rather than juggling devices, and choose an open-ear fit that doesn't block your ear canal. The LAMA's hook design is made to sit alongside a helmet and glasses, while the HZMFNWX wraps around the ear for a secure, pressure-light fit. Check your local rules on riding with audio before you head out.
what are the best cycling headphones
In my opinion, the best cycling headphones are open-ear ones that preserve environmental awareness. Between these two, the LAMA Bone Conduction Headphones are the stronger cycling pick on paper thanks to bone conduction, Bluetooth 5.4, up to 15 hours of playtime and IP55 sweat and water resistance. The HZMFNWX Air Conduction Open-Ear is the better choice if you want a lighter, simpler headset that also handles calls.
can cyclists wear headphones
Yes, though the safe approach is an open-ear design that doesn't seal off your hearing. Both headsets here are built around that idea — LAMA through bone conduction, HZMFNWX through air conduction — so you stay aware of your surroundings while listening. If you ride in dense traffic, prioritise models with clear environmental awareness like these rather than noise-isolating earbuds.
