If you want a featherweight neckband that recharges in minutes and stays put through sweat and rain, choose One Plus Bullets; if you need full over-ear immersion with serious active noise cancelling and marathon battery life, choose Morpheus 360 Eclipse SPT Hybrid.
• One Plus Bullets — biggest strength: 36 hours of playback with an absurdly fast top-up (10 minutes of charging reportedly returns 27 hours), in a 26 g silicone neckband rated IP55.
• One Plus Bullets — biggest trade-off: It's an in-ear neckband with no wired option and no manufacturer warranty — the listing states the seller covers 30-day returns instead.
• Morpheus 360 Eclipse SPT Hybrid — biggest strength: Hybrid ANC that cuts ambient noise by up to 45 dB, 80 hours of playtime, and a 40 mm graphene driver in over-ear form.
• Morpheus 360 Eclipse SPT Hybrid — biggest trade-off: At 1.2 pounds it's a bulkier, heavier over-ear set, and it costs more desk/backpack space than a neckband.
• Pick One Plus Bullets if you want grab-and-go earbuds for runs, commutes and calls.
• Pick Morpheus 360 Eclipse SPT Hybrid if you want to shut the world out for hours on a plane, in an office, or on the couch.
The Bullets Wireless Z3 is a neckband, and that single design choice explains everything good about it. There are no loose buds to lose, no case to dig for. It hangs around your neck, you pop the eartips in, and you're listening. The 26 g weight is the number that matters here — that's light by neckband standards, and paired with the skin-friendly silicone band it's built to disappear on you during a long day.
The headline feature is the charging math. Ten minutes on the cable gets you a claimed 27 hours of playback, with a full charge rated at 36 hours of listening and 21 hours of talk time. If you're the kind of person who always forgets to charge until the last second, that's the whole pitch. The 12.4 mm dynamic bass drivers and 3D Spatial Audio handle the fun part, and the Sound Master EQ with BassWave gives you four presets so you can lean bassy or flatten it out depending on what you're playing.
On the practical side: Bluetooth 5.4 with Google Fast Pair means quick pairing on Android, AI call noise cancellation keeps your voice usable on windy streets, and IP55 water and sweat resistance means a rainy run or a sweaty gym session won't kill it. Touch controls on the band handle playback without pulling out your phone.
Who should skip it? Anyone who wants true noise cancelling. There's active noise cancellation listed, but this is an in-ear design — the isolation comes mostly from the seal, not from a hybrid ANC array. If you fly a lot or work in a noisy open office and want the world genuinely muted, an in-ear neckband won't get you there. Also note the warranty description: this device isn't covered by a manufacturer's warranty, with 30-day free returns handled by the seller. That's a real consideration for a product you'll wear daily.
The Eclipse SPT Hybrid is the opposite philosophy. It's an over-ear headphone with oval earcups, a cushioned headband, and an ABS-and-stainless-steel build. At 1.2 pounds it's substantial, and that mass buys you two things a neckband can't offer: passive isolation from the cups sitting over your ears, and room for a proper ANC system.
That ANC is the centerpiece. Morpheus 360 describes a hybrid setup using six MEMS microphones — two measuring outside noise, two measuring what you're hearing inside the cups — feeding an AI algorithm that reduces ambient noise by up to 45 dB. There's also a physical ANC button so you can switch it off when you need to hear a gate announcement or a coworker without taking the headphones off. Two extra ENC microphones handle voice pickup for calls.
Battery life is the other headline: up to 80 hours. That's not a typo — it's over twice what the Bullets claim. For a remote worker, a long-haul flight, or someone who simply refuses to think about charging, that's the number that wins. The 40 mm graphene dynamic drivers cover 20 Hz upward with a 32-ohm impedance, tuned for crisp highs, balanced mids and deep bass — a more neutral-leaning signature than the bass-first Bullets. Audio latency is listed at 22 ms, which matters if you're gaming or watching video and hate lip-sync drift.
Connectivity is genuinely flexible: Bluetooth wireless plus a 3.5 mm jack, so you can go wired on a plane or a dead-battery emergency, and a Type-C to Type-C cable is in the box. Bluetooth range is rated at 10 meters. It ships with a hard shell case (roughly 8.5 x 2.5 x 7.25 inches, 4 ounces) in faux leather, and it folds for travel.
Side-by-Side: Which Should You Choose?
• Best for battery life → Morpheus 360 Eclipse SPT Hybrid. Up to 80 hours versus 36 hours on the Bullets.
• Best for fast top-ups → One Plus Bullets. Ten minutes of charging for a claimed 27 hours of playback is a genuinely unusual convenience.
• Best for noise cancelling → Morpheus 360 Eclipse SPT Hybrid. Hybrid ANC rated to cut noise by up to 45 dB, with six MEMS mics, versus the Bullets' in-ear seal and ANC listing.
• Best for workouts and rain → One Plus Bullets. IP55 sweat and water resistance and a 26 g neckband you'll forget you're wearing.
• Best for flights, offices and focused work → Morpheus 360 Eclipse SPT Hybrid. Over-ear cups plus switchable ANC plus 80 hours is the long-haul combo.
• Best for wired fallback → Morpheus 360 Eclipse SPT Hybrid. It has a 3.5 mm jack; the Bullets are wireless-only.
• Best for gaming and video → Morpheus 360 Eclipse SPT Hybrid. 22 ms latency and a 3D spatial audio implementation built with multi-dimension mapping.
• Best for calls on the move → One Plus Bullets. AI call noise cancellation and a light neckband suit walking meetings and street calls.
• Best all-day comfort under a hat or helmet → One Plus Bullets. Nothing over your ears, nothing on your head.
In my opinion, the Morpheus 360 Eclipse SPT Hybrid is the better buy for most people who listen at a desk, on a plane, or at home — the 45 dB hybrid ANC, 80-hour battery, wired fallback and included hard case make it the more complete package, and the 40 mm graphene drivers suit a wider range of music than a bass-forward tuning. I'd choose the One Plus Bullets only if portability is the deciding factor: if you run, sweat, and want earbuds that live around your neck and charge in ten minutes, nothing in the Eclipse's spec sheet helps you there. Two different jobs, two different answers — pick the one that matches your day, then check the current price on Amazon before you commit.
Yes, by design. The Eclipse uses hybrid ANC with six MEMS microphones and claims up to 45 dB of noise reduction, while the Bullets rely mainly on the in-ear seal plus an ANC listing. For planes, offices and commutes, the over-ear hybrid is the stronger choice.
The Bullets are rated at 36 hours of playback and 21 hours of talk time, with ten minutes of charging returning 27 hours. The Eclipse is rated at up to 80 hours. If charging less often matters more than charging fast, the Eclipse wins.
Yes. It has a 3.5 mm jack in addition to Bluetooth, and a Type-C to Type-C charging/audio cable is included. The One Plus Bullets are wireless only, with no headphone jack.
The One Plus Bullets. Its 26 g silicone neckband and IP55 water and sweat resistance are built for movement, while the Eclipse is a 1.2-pound over-ear headphone meant for seated or stationary listening.
