• iJoy Disney Nightmare Before — biggest strength: A themed Sally Dress design paired with IPX8 waterproofing and a truly wireless in-ear fit that follows the ear's contours.
• iJoy Disney Nightmare Before — biggest trade-off: No noise cancellation at all, and the Bluetooth 5.0 spec trails the newer standard on the Promise.
• Promise A12 — biggest strength: Up to 60 hours of playtime, a 280mAh battery, and a clever built-in Type-C adapter that charges straight from your phone or laptop.
• Promise A12 — biggest trade-off: It's a neckband, not a pocketable true-wireless set, and despite what the controls field says, the product itself states it is not ANC.
• Who should pick iJoy: Disney fans and gym-goers who want sweat-proof, cable-free buds with a case that recharges on the go.
• Who should pick Promise A12: Commuters, travelers and long-haul drivers who want to go days between charges and never hunt for a cable.
The iJoy Disney Nightmare Before Christmas Sally Dress TWS earbuds are, first and foremost, a character piece. The colorway and themed enclosure make them a collectible as much as a listening device, and if you or the person you're buying for has any attachment to the film, that matters more than a spec sheet ever will. But there's real hardware under the paint: a dynamic driver covering 20 Hz to 20,000 Hz, Bluetooth 5.0 with HSP, HFP, A2DP and AVRCP support, and a stated latency of just 15 milliseconds.
That latency figure is the detail I keep coming back to. Fifteen milliseconds is low enough that lip-sync drift in video and casual mobile gaming stays basically unnoticeable, which is unusual for a themed novelty set. Pairing is straightforward across phones, laptops and tablets, and the touch controls handle media without you digging for your phone. The in-ear shape uses rounded silicone tips that follow the ear's contour, so they're built to stay put through movement rather than fall out mid-set.
Battery is the other headline. iJoy rates the buds at 30 hours of talk time with 20+ hours of standby, and the case carries a 300mAh cell rated for roughly 180 hours — a full case recharge takes about 1.5 hours, and the buds themselves top up in an hour. Combined with IPX8 waterproofing and a sweat-proof build, that's a genuinely gym-ready package, and the 60-day replacement guarantee is a nice safety net.
Who should skip it? Anyone who wants silence on a plane or a train. There is no noise control here of any kind — no ANC, not even a passive noise-cancelling claim. And if you're a battery maximalist who resents charging anything, the Promise A12's numbers will look better to you.
The Promise A12 takes the opposite approach. Instead of tiny buds in a case, you get a neckband built from skin-friendly silicone over flexible memory steel, with a balanced armature driver and a stated range of 20 Hz to 20,000 Hz. Magnets snap the two earpieces together when you're not listening, so the band hangs around your neck without tangling or sliding off. It's a design that disappears on your shoulders in a way true-wireless buds never quite do.
The battery story is the reason to buy it. A 280mAh cell is rated for up to 60 hours of continuous music or talk time and around 200 hours of standby, with a one-hour charge time. For a long-haul driver, a frequent flyer, or someone with a week of commutes ahead, that's the difference between charging nightly and charging weekly. The built-in Type-C adapter is the clever bit: the earbud cap doubles as a plug, so you can charge directly from a phone, laptop or tablet with no cable at all. That's a genuinely useful trick when you're away from an outlet.
Audio flexibility is the second selling point. Three EQ modes — Bass, 3D Balance and Vocal — let you shift the tuning toward thump, everyday multimedia, or speech clarity for podcasts and calls. Bluetooth 5.3 gives you a stated 10–20 metre range with fewer dropouts during gaming and streaming, and there's intelligent mic noise reduction for calls.
Here's the honest caveat: this is not ANC. The spec sheet's noise control field says active noise cancellation, but the product's own description explicitly states it is designed for clearer voice calls and is not active noise cancelling. Trust the description. If your goal is blocking out engine roar, neither of these two will do it. The warranty is also notably shorter — a 2-month return policy rather than a longer guarantee.
• Best for battery life → Promise A12. 60 hours of playtime and 200 hours standby against iJoy's 30 hours talk time. Not close.
• Best for the gym and swimming-adjacent sweat → iJoy Disney Nightmare Before. IPX8 waterproofing and a sweat-proof build are stated; the Promise sheet lists no water resistance at all.
• Best for charging convenience → Promise A12. The built-in Type-C adapter means no cable needed, ever. The iJoy case is wireless-charging capable and needs 1.5 hours.
• Best for a themed gift or Disney fan → iJoy Disney Nightmare Before. The Sally Dress design and glow-in-the-dark treatment are the whole point.
• Best for long-haul drivers and travelers → Promise A12. The neckband format plus week-long battery is built for exactly that use case.
• Best for low-latency video and gaming → iJoy Disney Nightmare Before. A stated 15 ms latency is a concrete advantage over the unlisted figure on the Promise.
• Best for call clarity in a noisy place → Promise A12. Intelligent mic noise reduction is stated; iJoy offers no equivalent claim.
• Best for people who hate neckbands → iJoy Disney Nightmare Before. True-wireless in-ear with a compact case is the more flexible everyday format.
If I had to pick one, I'd take the Promise A12. In my opinion, 60 hours of playtime and a charging adapter built into the earbud itself solve the two problems that actually annoy wireless headphone owners — dying mid-day and forgetting the cable. The three EQ modes and Bluetooth 5.3 are the kind of practical flexibility that keeps a set in your bag for years. I'd only steer you to the iJoy Disney Nightmare Before if the theme is the reason you're buying, or if you need IPX8 waterproofing and true-wireless freedom for training. If you want the theme, buy the theme — just know the battery and connectivity numbers favor the Promise.
No. The product description states clearly that it is designed for clearer voice calls and is not active noise cancelling. You get mic noise reduction for calls, but environmental sound like engine noise or chatter will come through.
The Promise A12, by a wide margin. It's rated for up to 60 hours of playtime with 200 hours of standby from a 280mAh battery. The iJoy set is rated for 30 hours of talk time plus a case rated around 180 hours, so the case extends total runtime — but the buds themselves run shorter per charge.
Yes, that's what they're built for. The iJoy set carries an IPX8 waterproof and sweat-proof rating, which is the stronger claim of the two. The Promise A12's spec sheet lists no water-resistance rating, so I'd keep it out of heavy sweat or rain.
Both handle calls, but differently. The iJoy buds support HFP with rich in-call stereo sound and a built-in mic. The Promise A12 adds intelligent mic noise reduction and a dedicated Vocal EQ mode, which in my view makes it the better pick for call-heavy days.
