How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a familiar in-ear neckband that stays put during sweaty workouts and keeps a long standby reserve between charges, choose Gigastone 5.0; if you need open-ear bone conduction that lets you hear traffic and conversation while you run or ride, choose HCMOBI Bone Conduction Headphones.
• Gigastone 5.0 biggest strength: A lightweight neckband that hangs on your neck, tucks into a bag with no fuss, and pairs over Bluetooth 5.0 — with an IPX4 rating for sweat, rain and splashes.
• Gigastone 5.0 biggest trade-off: Traditional in-ear earpieces seal your canal, so you get sound isolation but far less awareness of traffic and surroundings.
• HCMOBI Bone Conduction Headphones biggest strength: A 0.9 oz open-ear titanium wrap that leaves your ear canals completely free, so you hear your music and the world at the same time.
• HCMOBI Bone Conduction Headphones biggest trade-off: Bone conduction trades deep bass and total isolation for safety and comfort, and the wrap-around frame is more visible on your head than a neckband.
• Choose Gigastone 5.0 if you want compact, pocketable, low-distraction audio for the gym, the office or calls.
• Choose HCMOBI Bone Conduction Headphones if you want situational awareness on runs, rides and hikes and can't stand anything sitting inside your ears.
The Gigastone 5.0 is a classic neckband headset, and that form factor is the whole point. Instead of two loose earbuds you have to chase around a gym bag, you get a single U-shaped unit that rests on your neck and connects over Bluetooth 5.0. The earpieces themselves are in-ear with a magnetic function, so they can snap together when you're not listening and dangle out of the way. It's a small design detail, but it's the kind of thing that matters when you're moving between sets or walking into a building.
On the spec sheet, the two headline numbers are the battery life and the IPX4 waterproof rating. Gigastone rates the headphone at 10 hours of music playback and 250 hours of standby time. That standby figure is the interesting one — it means you can leave the headset in a bag for days or weeks and still expect it to wake up with a charge when you need it. The IPX4 rating covers sweat, rain and splashing water, which is exactly the exposure you get from a hard gym session or a drizzly commute. It is not a rating for swimming or submerging, so keep it out of the pool.
Audio runs from 20Hz to 20,000Hz, the standard full-range window, and the unit supports A2DP stereo sound. Controls are handled remotely — media control from the headset rather than the phone. Gigastone also backs the N1 with a 1-year manufacturer warranty with replacement and online service, which is a reasonable safety net for a plastic-bodied sports headset.
Who should buy it: Anyone who wants an inexpensive-feeling, low-maintenance headset for the gym, the office, commuting or calls, and who actually prefers the sealed-in sound of an in-ear fit. If you like the idea of a neckband you can wear all day and forget about, this is the shape you want.
Who should skip it: Runners and cyclists who need to hear cars and other people. In-ear headphones block your canal by design, and the Gigastone 5.0 does nothing to counteract that. If awareness is your priority, this is the wrong category of headphone.
The HCMOBI set takes the opposite approach: nothing goes in your ears at all. These are open-ear bone conduction headphones, which means the drivers sit against your cheekbones and send vibration through bone to your inner ear, leaving your ear canals open to the environment. HCMOBI describes the tech as a non-vibrating bone conduction design, with tuning aimed at louder highs, softer mids and heavier bass. That tuning note matters — bone conduction is not known for thumping low end, so a manufacturer emphasizing bass is acknowledging the weak spot and trying to work around it.
The frame is the other story. It's a wrap-around titanium headband weighing just 0.9 ounces (25.54 grams on the spec sheet), with silicone and plastic in the build. Titanium is chosen here for ductility: the band can be folded and springs back to shape, which helps it survive being stuffed in a bag and adapt to different head sizes. For anyone who's abandoned earbuds because of ear pain after an hour, the bud-free ergonomic fit is the whole argument.
Battery is 10 hours of continuous music, calls, audiobooks or podcasts from a 220mAh cell, charged over USB-C with both sides usable for charging. HCMOBI claims 20 minutes of charging yields up to 2 hours of playback, with a full charge taking about 1.5 hours. Connectivity is Bluetooth 5.2 — a step newer than the Gigastone's 5.0 — and the company says it uses a Qualcomm chip for a more stable signal, with compatibility across Android, iOS, TVs and video-conferencing setups. There's a noise-cancelling microphone for calls and individual buttons for control. The IPX4 rating covers sweat, dust, oil and particles. Warranty is 12 months with a 90-day money-back window.
Who should buy it: Runners, cyclists, hikers and gym-goers who need to stay aware of their surroundings, plus remote workers who take a lot of video calls and hate having something jammed in their ears. It also suits anyone who finds in-ear fit uncomfortable over long sessions.
Who should skip it: People who want serious bass, total isolation on a plane or train, or an invisible look. Bone conduction is intentionally leaky and intentionally visible.
• Best for situational awareness → HCMOBI. Open-ear design keeps traffic, voices and hazards audible; the Gigastone's in-ear seal does the opposite.
• Best for long-term standby → Gigastone 5.0. 250 hours of standby means it survives weeks in a drawer; HCMOBI doesn't publish a standby figure.
• Best for a newer Bluetooth standard → HCMOBI. Bluetooth 5.2 versus Bluetooth 5.0 on the Gigastone.
• Best for charging convenience → HCMOBI. USB-C with dual-sided charging and a claimed 20-minutes-for-2-hours top-up; the Gigastone sheet doesn't specify a charge time or port.
• Best for ear-comfort over long wear → HCMOBI. 0.9 oz, bud-free, titanium wrap that flexes back into shape.
• Best for sealed, focused listening → Gigastone 5.0. In-ear earpieces isolate you from the room, which helps in a noisy open office or on a call.
• Best for a compact, packable carry → Gigastone 5.0. A neckband with magnetic earpieces is easier to fold away than a rigid headband.
• Best for calls and remote work → HCMOBI. A noise-cancelling mic and broad device compatibility are called out specifically for conferencing.
If I were buying one of these for myself, I'd pick the HCMOBI Bone Conduction Headphones. In my opinion, the open-ear design is the more useful feature in 2026, because it solves two problems at once: it keeps your ears pain-free during long sessions and it keeps you aware of what's happening around you while you run, ride or walk. The Bluetooth 5.2 connection, USB-C fast charging, 0.9 oz titanium frame and noise-cancelling mic make it the more complete package for the way most people actually use sports headphones. I'd only steer you to the Gigastone 5.0 if you specifically want sealed in-ear sound and the reassurance of that enormous 250-hour standby reserve. Both carry IPX4, so on water resistance they're level — the decision is really about open ear versus in ear.
can i wear waterproof headphones in the shower
It depends on the rating. Both of these are rated IPX4, which the manufacturers describe as protection from sweat, rain and splashing water — not immersion. A shower's direct spray is a gray area, and neither sheet claims submersion protection, so I wouldn't treat either one as a shower-safe headphone. For washing up, keep them off your head.
are headphones waterproof
Not automatically. "Waterproof" and "water-resistant" get used loosely, and the real answer is in the IP rating. An IPX4 rating — what both the Gigastone 5.0 and the HCMOBI headset carry — means splash and sweat resistance, not the ability to survive being submerged. If you need to swim with headphones, neither of these is the right pick.
which one is better for running outside
The HCMOBI Bone Conduction Headphones, in my opinion. Its open-ear design leaves your ear canals free so you can hear cars, bikes and other people, which is the safety argument for bone conduction in the first place. The Gigastone 5.0 seals your ears, so you'd be relying on the volume being low enough to hear hazards.
does the Gigastone 5.0 have a longer battery life than the HCMOBI
On playback they're even — both are rated at 10 hours of music. The difference is standby: Gigastone lists 250 hours of standby time while the HCMOBI sheet doesn't publish a standby figure, so if you want a headset that holds a charge between infrequent uses, the Gigastone has the clearer claim.
