• JOMILIN B9 — biggest strength: up to 60 hours of playtime per charge, a 2-hour charge time, and Bluetooth 5.3 plus a 3.5 mm jack so it works wirelessly or wired.
• JOMILIN B9 — biggest trade-off: it's an over-ear headphone that weighs 7.01 ounces and relies on passive sound isolation, so it's bulkier and less pocketable than a tiny earbud.
• Skullcandy Jib USB-C — biggest strength: a wired USB-C connection with an in-line mic and call/track controls, so there's nothing to charge and nothing to pair.
• Skullcandy Jib USB-C — biggest trade-off: it's wired-only with a USB-C plug, so it needs a USB-C port and it lives or dies by that cable.
• Who JOMILIN B9 is for: long-haul travelers, work-from-home callers and anyone who wants over-ear comfort for hours at a time.
• Who Skullcandy Jib USB-C is for: commuters and phone-first listeners who want small, always-ready earbuds they can plug into a modern phone.
The JOMILIN B9 is built around one idea: keep going. The playtime figure here is 60 hours on a single charge, and a full charge takes about 2 hours. That combination is the headline. If you've ever had a headphone die halfway through a flight, a long shift, or a weekend of on-and-off listening, this is the spec that matters. A 2-hour top-up is short enough that you can charge it while you unpack, and 60 hours is long enough that you can forget about the charger for a while.
The second thing to know is the flexibility. This is primarily a Bluetooth 5.3 headphone with a 10-meter wireless range, but it also has a 3.5 mm jack. In the description of the design, that wired mode is presented as a fallback once the battery runs down — which means you're not stuck with a dead headphone if you forgot to charge it. It can also fold, which is the detail that makes it a genuinely portable over-ear rather than a desk fixture. Folded down, it takes up less room in a bag, and the brand includes a carrying case in the box.
Who should buy it: travelers, students, remote workers, and anyone who wants one headphone for both wireless and wired use. Who should skip it: if you want something that disappears into a jeans pocket, or you specifically want active noise cancellation, this isn't the pick. It weighs 7.01 ounces and it's an over-ear, so it's a bag item, not a pocket item.
Skullcandy Jib USB-C: Who It's For
The Skullcandy Jib USB-C is the opposite philosophy, and that's the point. It's a wired in-ear bud that plugs straight into a USB-C port. There is no battery, no pairing, no charging case, and no Bluetooth handshake to troubleshoot. You plug it in and it works. For anyone who has stood on a platform waiting for a pair of earbuds to connect while the train arrives, that simplicity is the entire appeal.
The fit story is handled with three sizes of ear gels, so you can size up or down until the bud seals properly. That seal does double duty: it's what gives you the noise-isolating effect and what keeps the low end from leaking away. The driver is a dynamic type with a 20 Hz – 20,000 Hz frequency range, 17 ohm impedance and 100 dB sensitivity — easy-to-drive numbers that a phone's USB-C output handles without effort. You don't need a headphone amp, a dongle, or a battery indicator.
Controls live on the in-line remote. There's a built-in microphone for calls, and call/track control so you can play, pause, and skip forward without pulling the phone out of your pocket. That's the practical stuff you actually use on a commute. The whole thing weighs 40 grams, which is about as close to nothing as a headphone gets.
Who should buy it: phone-first listeners, commuters, gym-goers, and anyone with a USB-C device who wants zero setup and zero charging. Who should skip it: if your device only has a 3.5 mm jack, or you want to move around untethered, this is the wrong tool. The cable is the connection and the limitation. There's also no active noise cancellation here — the isolation comes from the ear gel seal, which is a different thing.
• Best for battery life → JOMILIN B9. Up to 60 hours per charge with a 2-hour charge time is the clear win.
• Best for zero-setup listening → Skullcandy Jib USB-C. Wired USB-C means no pairing and no charging, ever.
• Best for over-ear comfort on long sessions → JOMILIN B9. Memory-protein earpads and an over-ear fit are made for hours of wear.
• Best for portability and pocket carry → Skullcandy Jib USB-C. At 40 grams with a built-in cable, it disappears into a pocket or bag pouch.
• Best for calls on the move → Skullcandy Jib USB-C. The in-line mic and remote put call and track control right on the cable.
• Best for mixed wireless and wired use → JOMILIN B9. Bluetooth 5.3 when you want freedom, 3.5 mm when you want a direct connection.
• Best for travel with a bag → JOMILIN B9. It folds and ships with a carrying case, so it packs down rather than tangling.
• Best for USB-C-only phones → Skullcandy Jib USB-C. It's designed around that port, so it plugs in and plays.
• Best for passive isolation in a noisy space → either, with a caveat. The B9 seals over your ear; the Jib seals in your ear canal. Neither offers active noise cancellation.
If I had to pick one for most people, I'd buy the JOMILIN B9. The 60-hour playtime, the 2-hour charge, the Bluetooth 5.3 wireless freedom plus a 3.5 mm wired fallback, and the folding over-ear design give it far more range of use. It's the headphone you can take on a trip, work through the afternoon in, and still have battery left. The Skullcandy Jib USB-C is the smarter buy only if you've decided you never want to think about charging or pairing again and you're happy staying tethered to a USB-C port. Both are honest, simple products — the B9 just does more jobs.
how to use external headphones on mac
If you're using the JOMILIN B9, pair it over Bluetooth 5.3 and select it as the output device; if you'd rather go wired, the 3.5 mm jack works with a Mac's headphone port or an adapter. The Skullcandy Jib USB-C needs a USB-C port, so on a Mac with only USB-C you plug straight in, while older Macs with a headphone jack would need an adapter.
how to connect mobile headphones
The JOMILIN B9 connects wirelessly over Bluetooth 5.3 within a 10-meter range, so you pair it once and it reconnects. The Skullcandy Jib USB-C doesn't pair at all — you plug the USB-C connector into your phone and the audio routes through it immediately.
how to connect c port headphones
USB-C headphones like the Skullcandy Jib USB-C simply plug into the USB-C port on your phone, tablet or laptop. There's no pairing step and no battery to check; the in-line remote handles play, pause, track skip and calls once it's seated.
how to pack headphones
The JOMILIN B9 folds and comes with a carrying case, so it stows flat in a bag without tangling. The Skullcandy Jib USB-C is a 40-gram in-ear bud, so it packs into a small pouch or pocket — just coil the cable loosely rather than wrapping it tight around the buds.
