How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a themed in-ear pair with a big battery and a case that doubles as a charger, choose iJoy Disney Nightmare Before; if you need open-ear awareness for running and cycling with the longest total playtime, choose 2B2C Open Ear Earbuds. One hugs your ear canal and stays there through a workout. The other leaves your ear canal open so traffic, bikes and people never disappear on you.
• iJoy Disney Nightmare Before — biggest strength: 30 hours of battery life per charge (plus a case rated for 180 hours) and IPX8 water/sweat resistance in a Bluetooth 5.0 in-ear design with 15 ms latency.
• iJoy Disney Nightmare Before — biggest trade-off: It's an in-ear, sealed design with no ambient awareness, and the look is locked into a Nightmare Before Christmas Sally Dress theme — great if you love it, limiting if you don't.
• 2B2C Open Ear Earbuds — biggest strength: Open-ear air-conduction fit, just 9 g per earbud, Bluetooth 5.3 and an LED display case good for roughly 10 extra charges.
• 2B2C Open Ear Earbuds — biggest trade-off: Only 8 hours per charge, no noise isolation by design, and a plastic-and-fabric build that reads as functional rather than premium.
• Who each is for: iJoy for someone who wants long single-charge listening, gym use and a themed design; 2B2C for runners, cyclists and commuters who want to hear the world while they listen.
The iJoy Disney Nightmare Before Christmas Sally Dress TWS Earbuds are built around two ideas: staying in your ears, and staying powered. The in-ear, rounded-tip shape with a contoured body is meant to sit tight and not shift, and the silicone enclosure keeps things soft against the skin. On paper, that's a gym-and-commute profile. IPX8 is the headline here — that's a genuinely high water-resistance rating for earbuds, which means sweat and rain are not the enemy they are for most budget buds.
Battery is where this pair pulls away. You get a claimed 30 hours of talk time, 20+ hours on standby, and a 300 mAh case that iJoy rates at 180 hours of carrying-case life and needs only 1.5 hours to refill. The earbuds themselves recharge in about an hour. Bluetooth 5.0 with HSP, HFP, A2DP and AVRCP support means pairing is broad and call audio is stereo, and a 15 ms latency figure is low enough that video lip-sync should feel natural rather than off.
The trade-offs are honest ones. There's no noise control of any kind, so isolation comes purely from the in-ear seal — fine in a gym, less ideal if you want to hear traffic. Controls are touch-based, which some people love and some people trigger by accident. And the Sally Dress theme is the whole point: if you're a Disney or Nightmare Before Christmas fan, this is a fun pick; if you want something that disappears into your bag, the design will feel loud.
Buy it if you want long battery, a secure in-ear fit, real sweat resistance and a themed look. Skip it if you need ambient awareness or a neutral, unbranded design.
The 2B2C Open Ear Earbuds go the opposite direction. These are open-ear, over-ear air-conduction headphones — nothing goes into your ear canal. At 9 g per earbud, the point is all-day wear without the pressure and heat that builds up with in-ear tips. If you've ever pulled earbuds out after two hours because your ears felt raw, this design is aimed squarely at you.
The safety angle is the real feature. Because your canal stays open, ambient sound reaches you: traffic, a cyclist calling out, a car door, your running partner. For running, cycling, hiking or even driving, that awareness matters more than bass. Bluetooth 5.3 gives a faster, more stable connection than older versions, and the 10-meter range is normal for this class. A multi-function button handles calls, volume and playback, so you're not fishing for your phone mid-run.
Battery works differently here. You get up to 8 hours of continuous playback per charge, a 2-hour full recharge, and a magnetic charging case that 2B2C says can deliver about 10 additional charges. The LED digital display is a small but genuinely useful touch — you can see how much case battery is left instead of guessing. A microphone handles calls, and the design is meant to reduce sound leakage so your audio stays yours.
Buy it if you run, ride, hike or work in environments where hearing your surroundings is non-negotiable. Skip it if you want maximum battery per charge or any real isolation.
Side-by-Side: Which Should You Choose?
• Best battery life per charge → iJoy Disney Nightmare Before (30 hours talk time vs 8 hours playback).
• Best for running and cycling safety → 2B2C Open Ear Earbuds (open-ear design lets ambient sound in).
• Best for the gym and sweaty workouts → iJoy Disney Nightmare Before (IPX8 water and sweat resistance).
• Best for all-day comfort → 2B2C Open Ear Earbuds (9 g per earbud, nothing inserted in the ear canal).
• Best for video and low-latency use → iJoy Disney Nightmare Before (15 ms latency, Bluetooth 5.0 with A2DP).
• Best for newer Bluetooth and easier pairing → 2B2C Open Ear Earbuds (Bluetooth 5.3 vs 5.0).
• Best for knowing your case battery → 2B2C Open Ear Earbuds (LED digital display on the case).
• Best for a themed, gift-friendly look → iJoy Disney Nightmare Before (Nightmare Before Christmas Sally Dress design).
In my opinion, the 2B2C Open Ear Earbuds are the better buy for most people who are shopping in this category, because the open-ear design solves a problem in-ear buds can't: staying aware while you're moving outdoors. The 9 g fit, Bluetooth 5.3, the LED case display and roughly 10 case recharges add up to a genuinely practical everyday package, and the 1-year warranty is reassuring.
That said, I'd pick the iJoy Disney Nightmare Before without hesitation if battery life, sweat resistance or a themed design is what you're after. Thirty hours per charge and IPX8 are hard specs to argue with. If your listening happens indoors, at a desk or in a gym, the iJoy wins on endurance and durability. If it happens on a road or a trail, the 2B2C wins on safety.
It depends on what you want from the run. The 2B2C open-ear design keeps ambient sound audible, which is safer on roads and trails. The iJoy has IPX8 sweat resistance and a secure in-ear fit, so it holds up to sweat better but blocks outside sound.
The iJoy is rated at 30 hours of talk time with a case rated for 180 hours. The 2B2C delivers up to 8 hours of continuous playback per charge, with its case providing roughly 10 additional charges.
No. Neither product lists active noise cancellation. The iJoy blocks sound passively through its in-ear seal, while the 2B2C is designed to let ambient noise in on purpose.
