How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired, sound-isolating pair that stays clamped on your ears during hard runs and gym sessions, choose ASKUBSKU USB C Headphones; if you need open-ear awareness on the road plus wireless freedom and a 10-hour battery, choose Gelecek Bone Conduction Headphones.
• ASKUBSKU's biggest strength: wired USB-C connection with no battery to manage, plus an over-ear hook that the design specifically aims at running and gym use, and in-ear sound isolation for louder, more enclosed audio.
• ASKUBSKU's biggest trade-off: it's a wired in-ear set, so the cable is always there and you lose awareness of traffic, people and ambient sound around you.
• Gelecek's biggest strength: open-ear bone conduction that keeps your ears clear for safety, on a 29-gram titanium frame with up to 10 hours of playtime and sweat-resistant IP55 construction.
• Gelecek's biggest trade-off: open-ear sound is intentionally less isolating, so noisy gyms and windy roads will bleed into what you hear, and it's wireless only.
• Who each is for: ASKUBSKU suits phone-and-gym athletes who want plug-and-play wired audio and don't mind a cable; Gelecek suits runners, cyclists and hikers who value awareness and a wireless fit over isolation.
The ASKUBSKU USB C Headphones are a wired, in-ear sport set built around a hook that wraps over the top of your ear. That hook is the whole point of the design: the brand positions these for running, jogging and gym work, and the over-ear hook is what keeps them from sliding out during the kind of movement that shakes loose ordinary buds. If you've ever had a plain earbud pop out mid-sprint, this is the category of product that exists to solve that.
The audio side is more interesting than most wired sport buds. There's a built-in DAC chip, which on a USB-C headphone is what lets the earbuds pull high-resolution audio directly from a digital source instead of relying on a basic analog signal. ASKUBSKU describes deep bass and clear treble. The driver is a dynamic driver, and the in-ear design is explicitly aimed at sound isolation, so outside noise gets pushed down and your music gets pushed forward. You also get three sizes of eartips, which matters more than people admit — the seal is what makes or breaks both comfort and bass on an in-ear set.
Compatibility is unusually broad for a USB-C headphone. It covers recent iPhone 15/16/17 Pro Max and Plus models, a long list of Samsung Galaxy S and Z-series phones, iPad, MacBook in several sizes, and Google Pixel 10 models. Controls are simple button controls on the cable. It's white, plastic, and comes with eartips and a protective case.
Gelecek Bone Conduction Headphones: Who It's For
The Gelecek Bone Conduction Headphones sit in a completely different philosophy. Instead of sealing your ear canal, they send sound through your cheekbones, which leaves your ears open to the world. That's the feature that matters most for outdoor athletes: you hear your music and the traffic, the cyclist behind you, the dog, the car. Gelecek frames this as a safety advantage over traditional in-ear and over-ear headphones, and for road runners and cyclists, that's not marketing fluff — it's the reason to buy this style at all.
The frame is titanium and weighs 29 grams, which is light enough to mostly forget about. Titanium also gives it flexibility: the brand says it can be stretched and bent without deforming, so it survives being tossed in a bag. Water resistance is rated IP55, and the feature list calls it sweatproof, which covers running, hiking and cycling. It's open-ear by design, with a bone-conduction driver rather than a traditional dynamic one.
Battery life is up to 10 hours, and charging is over USB-C — fast charging is mentioned. It's wireless, and the spec sheet lists Bluetooth 5.4, though the title itself says Bluetooth 6.0; either way, it's a current-generation wireless connection. There's a mic, and the noise-cancelling feature is aimed at calls — Gelecek specifically mentions remote video conferences and long meetings. The color is a Space Gray finish, and it ships with an adapter.
Buy these if you run, ride or hike near traffic and want your ears free, or if you want a wireless set you can wear for a full training block without thinking about a cable. Skip them if you train in a loud gym and want your music to block everything out — open-ear design works against you there.
• Best for road safety → Gelecek Bone Conduction Headphones. Open-ear design keeps you aware of your surroundings; ASKUBSKU's sound isolation does the opposite.
• Best for intense gym work and sprints → ASKUBSKU USB C Headphones. The over-ear hook is purpose-built to resist falling out during hard movement.
• Best for battery-free reliability → ASKUBSKU USB C Headphones. It's wired, so there's no charging and no pairing — plug into a USB-C port and go.
• Best for long sessions away from a charger → Gelecek Bone Conduction Headphones. Up to 10 hours per charge on a 29-gram titanium frame.
• Best for loud, immersive audio → ASKUBSKU USB C Headphones. A dynamic driver plus a DAC chip and in-ear isolation is the more enclosed, bass-forward listen.
• Best for calls and meetings → Gelecek Bone Conduction Headphones. It has a mic with a noise-cancelling feature aimed at hands-free calls and video conferences.
• Best for sweat and weather → Gelecek Bone Conduction Headphones. IP55 water resistance and a sweatproof build; ASKUBSKU doesn't publish a water-resistance rating.
• Best for wired phone and laptop users → ASKUBSKU USB C Headphones. The compatibility list spans recent iPhone, Galaxy, Pixel, iPad and MacBook models.
In my opinion, the Gelecek Bone Conduction Headphones are the better pick for most people who describe what they do as "sports headphones." The combination of open-ear awareness, a light titanium frame, IP55 sweat resistance and up to 10 hours of wireless playtime matches how most runners, cyclists and hikers actually train — outdoors, moving, and needing to hear the world. I'd choose ASKUBSKU USB C Headphones instead if my training is mostly indoors, if I want stronger isolation and bass, or if I simply refuse to deal with charging and pairing. Cable-free safety versus wired, sealed sound — that's the real decision here.
how to wear running headphones
For the Gelecek set, hook the titanium band over your ears so the transducers rest against your cheekbones, just in front of your ears — bone conduction needs contact with bone, not your ear canal. For ASKUBSKU, push the in-ear tip in for a seal, then loop the over-ear hook behind your ear so the cable runs down your back. Pick the eartip size that seals without pressure.
how to charge impact sport headphones
The Gelecek Bone Conduction Headphones charge over USB-C and the brand lists fast charging support, so a standard USB-C cable into a USB-C port is all you need. ASKUBSKU USB C Headphones have no battery at all — they draw power from whatever USB-C device they're plugged into, so there's nothing to charge.
how to pair jlab sport headphones
Pairing steps vary by brand, and neither of these two models is a JLab product, so check your specific model's manual. For the Gelecek set, which is the wireless option here, the process is the standard one: power it on, put it in pairing mode, then select it from your phone's Bluetooth list. ASKUBSKU is wired and doesn't pair at all — you just plug it in.
how to use sports headphones
Match the design to the activity. Use the Gelecek open-ear set for outdoor runs, rides and hikes where you want to hear traffic, and take calls with its mic when needed. Use the ASKUBSKU hooked in-ears for gym sessions or indoor work where you want isolation and deeper bass, and plug them straight into a USB-C phone, tablet or laptop.
