How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want marathon battery life and a single pair of on-ear headphones that flips between your laptop and phone all day, choose JLab; if you need open-ear earbuds that stay put while you run and let you hear traffic around you, choose QCY Crossky C30.
• JLab's biggest strength: 40+ hours of Bluetooth 5.3 playtime with multipoint pairing, so it can ride through a full commute week on one charge while staying connected to two devices at once.
• JLab's biggest trade-off: It's an on-ear design that isolates sound by sealing over your ear, so you won't hear much of what's happening around you — and there's no charging case, just a foldable frame.
• QCY Crossky C30's biggest strength: A C-shape open-ear clip-on fit that keeps your ear canal open to your surroundings, backed by Bluetooth 5.4 and IPX4 water resistance for workouts.
• QCY Crossky C30's biggest trade-off: Battery life is measured in hours, not days — about 5.5 hours per charge, stretched to roughly 25 hours with the charging case.
• Who JLab is for: Commuters, students and desk workers who want one pair of headphones to juggle a phone and a laptop and rarely think about charging.
• Who QCY Crossky C30 is for: Runners, cyclists and gym-goers who want earbuds that stay stable, survive sweat and let ambient sound in.
JLab's Studio+ Gen 2 is built around one idea: keep you connected and keep you listening for a long time. The headline number is 40+ hours of Bluetooth 5.3 playtime, and that figure is based on music playing at medium volume. For most people that means charging once at the start of the week and not thinking about it again until the weekend. If you've ever had earbuds die on the second half of a long flight or a back-to-back meeting day, that's the problem this design solves.
The multipoint story is the other half of the pitch. Bluetooth 5.3 multipoint lets you connect to two devices at the same time — say a laptop and a phone — so a call can come in on your phone while you're listening to something on your computer. Google Fast Pair makes the Android side quick, and the headphones are listed as compatible with iOS, Android and PC. The JLab App adds control: you can remap the touch controls and dial in EQ. Onboard you get three presets — JLab Signature, Balanced and Bass Boost — so you can shift the sound without opening an app at all.
Who should buy it: anyone who wants one pair of headphones for the desk, the commute and the couch, values not charging constantly, and actually uses multipoint to hop between two devices. Who should skip it: people who need to stay aware of their surroundings, anyone who wants a compact charging case, and listeners who specifically want active noise cancellation — JLab offers isolation, not ANC.
QCY Crossky C30: Who It's For
The QCY Crossky C30 goes after a completely different job. It's an open-ear, clip-on design — C-shape, sitting outside the ear canal rather than sealing it. That's the defining feature, and it drives everything else. You get stability on the move and you stay in sync with your surroundings, which is exactly what you want when you're running on a road, cycling, or lifting in a busy gym. Nothing is jammed into your ear, so there's no plugged-up feeling and no pressure build-up over a long session.
Sound comes from a 10.8 mm dual-magnet high-sensitivity driver, with a frequency range of 20Hz to 20,000Hz and 50 ohm impedance. For calls, four built-in microphones work with an intelligent algorithm to pick up and amplify your voice out of a noisy environment — QCY labels this ENC noise cancelling, which is about call clarity rather than blocking the world out. Note the spec sheet also lists active noise cancellation under noise control, so treat the noise story as call-focused rather than a promise of silence.
Connectivity is Bluetooth 5.4 with dual connection — two devices at once, so you can watch something on a TV and still take a call without re-pairing. QCY also claims a 15-meter Bluetooth range and 80 ms low latency, which matters if you're watching video and don't want lip-sync drift. Battery is 5.5 hours per charge, or up to 25 hours with the charging case, and the case carries a 400 mAh battery. IPX4 water resistance covers sweat and light rain. The QCY app handles EQ modes, button remapping, real-time power info and firmware updates.
Who should buy it: runners, cyclists, gym users and anyone who wants to hear what's going on around them while listening. Who should skip it: people who want long uninterrupted battery life, listeners who want the isolation of a sealed on-ear or in-ear fit, and anyone who dislikes charging a case every day or two. The whole kit weighs in around 43 g, and it ships with a charging station, ear cushions, a Type-C cable and a manual.
• Best for battery life → JLab. 40+ hours versus 5.5 hours per charge (25 hours with the case) is not close.
• Best for awareness of your surroundings → QCY Crossky C30. The open-ear C-shape never seals the canal, so traffic, gym announcements and training partners stay audible.
• Best for multipoint across a laptop and phone → JLab. Bluetooth 5.3 multipoint with Google Fast Pair is aimed squarely at the work-and-commute switch.
• Best for dual-device movie-and-call switching → QCY Crossky C30. Bluetooth 5.4 dual connection plus 80 ms low latency is tuned for screen time.
• Best for workouts and sweat → QCY Crossky C30. IPX4 water resistance and a stable clip-on fit are built for movement; JLab's on-ear design is not marketed for sweat.
• Best for all-day comfort without ear fatigue → QCY Crossky C30. Nothing enters the ear canal, so long sessions don't create the pressure an on-ear seal can.
• Best for folding into a bag → JLab. The frame collapses flat, while QCY relies on its charging case for transport.
• Best for call clarity in noise → QCY Crossky C30. Four microphones with an intelligent algorithm are dedicated to pulling your voice out of a crowd.
In my opinion, the right pick comes down to whether you're buying for a desk or for a road. If your day is meetings, commutes and switching between a laptop and a phone, I'd buy the JLab Studio+ Gen 2 — 40+ hours of Bluetooth 5.3 multipoint playtime, a two-year warranty and a foldable frame make it the more practical everyday pair. If your priority is running, cycling or training while staying aware of what's around you, I'd take the QCY Crossky C30 and accept the shorter battery in exchange for the open-ear fit, IPX4 rating and 5.4 dual connection. Neither is a compromise pick — they just solve different problems.
FAQ
how to pair multiple headphones
how to pair multiple headphones iphone
On iPhone, open Settings and Bluetooth and pair each headphone individually; iOS will remember them, but you still switch between them manually. For two devices at once on a single pair, you need multipoint support, which both of these models list — Bluetooth 5.3 on the JLab and Bluetooth 5.4 on the QCY Crossky C30.
how to pair multiple headphones on ipad
On iPad, the process is the same as iPhone: Settings, Bluetooth, and pair each set. The iPad can hold several paired devices, but only the multipoint-capable pair can stay connected to two sources at the same time, so check that feature before assuming seamless switching.
how to pair multiple bluetooth headphones
You can pair several Bluetooth headphones to one phone, tablet or computer, but most devices only play audio through one at a time. If your goal is fewer re-pairing steps, look for multipoint: the JLab handles two devices over Bluetooth 5.3, and the QCY Crossky C30 handles two over Bluetooth 5.4.
