If you want a stable, open-ear neckband for workout sessions where you still need to hear traffic and your surroundings, choose Horett Headphone Neckband Lightweight; if you need feather-light in-ear buds that stay comfortable through a full night of side sleeping and block out noise, choose Ertuly Sleep Earbuds. These two products both sell themselves as "ultra lightweight," but they solve completely different problems — one is built to move with you outdoors, the other is built to disappear inside your ear at bedtime.
• Horett's biggest strength: an air conduction, open-ear neckband design with heavy bass and no ear insertion, plus a full charge in about 1 hour and an LED power display.
• Horett's biggest trade-off: an open-ear fit means it won't seal out outside noise — that's the point for running and cycling, but it's the wrong tool for blocking a noisy room.
• Ertuly's biggest strength: 3 grams per earbud with an ergonomic side-sleeper shape, soft skin-friendly materials, and ANC for a quieter sleep environment.
• Ertuly's biggest trade-off: up to 6 hours per charge (30 hours with the case) is fine overnight, but it's a sleep-first design, not a sport-first one.
• Buy Horett Headphone Neckband Lightweight if you want a stable neckband that stays put while running, cycling or lifting and keeps you aware of your surroundings.
• Buy Ertuly Sleep Earbuds if you want near-weightless buds that let you lie on your side and mute snoring, city noise or household sounds.
The Horett neckband is the pick for anyone who treats headphones as training gear. The design is a wireless neckband that sits around your neck rather than inside your ear canal, and that single decision shapes everything else. Because it uses air conduction instead of an inserted tip, it can push what the spec sheet calls "heavy bass effects" while your ears stay open. In practice that means you can hear a car, a cyclist or a training partner while your music keeps playing — which is exactly what you want on a run or a ride around town.
Who should buy it? Runners, cyclists, gym-goers, and anyone who wants an open-ear feel with a secure, hard-to-lose form factor. If you've ever had a bud pop out on a treadmill or while dodging traffic, the neckband shape is the fix. Who should skip it? If your main goal is blocking noise — for sleep, for a noisy commute, for focus in an open office — an air conduction design is deliberately the opposite of that. It also won't suit you if you prefer true in-ear isolation or a fully invisible fit.
Ertuly Sleep Earbuds: Who It's For
The Ertuly Sleep Earbuds are built around one very specific body position: side sleeping. Each earbud weighs only 3 grams, and the ergonomic shape is designed to sit snugly without pressing into your ear when your head is on a pillow. That's the whole pitch, and it's a real problem worth solving — most earbuds become painful the moment you roll onto your side. The materials are described as skin-friendly and smooth, aimed at reducing irritation and soreness during extended wear, which matters if you keep them in for a full night or a long meditation session.
The second half of the job is noise. These use Active Noise Cancelling to take the edge off snoring, city noise and household sounds, and the design is deliberately compact and unobtrusive so it doesn't interfere with sleep. Battery life is quoted at up to 6 hours of continuous playtime and up to 30 hours total with the charging case, with an LED display on the case and buds so you can monitor power — enough for a night, and the case covers a stretch of nights. Bluetooth 5.4 with a range up to 33 feet and touch controls round out the package, and the box includes the two earbuds, four earplugs, a cable and a manual.
Who should buy it? Side sleepers, light sleepers, people with sensitive ears, and anyone who wants to mask noise at night or during relaxation without a bulky headband or over-ear cup pressing into their skull. Who should skip it? If you're shopping primarily for intense workouts, a 3-gram sleep bud with a 6-hour per-charge ceiling is the wrong priority — sweat-heavy sessions and long outdoor runs aren't what this design is optimized for. It's also not for you if you want to stay aware of your surroundings, since ANC does the opposite.
• Best for workout and outdoor training → Horett Headphone Neckband Lightweight. The neckband stays stable through running, cycling and gym work, and the open-ear air conduction design keeps you aware of traffic.
• Best for side sleeping and overnight wear → Ertuly Sleep Earbuds. 3 grams per bud and a side-sleeper shape are purpose-built for a pillow.
• Best for noise blocking → Ertuly Sleep Earbuds. ANC is the feature you want against snoring, city noise and household sounds.
• Best for staying aware of your surroundings → Horett Headphone Neckband Lightweight. Air conduction doesn't seal your ear canal, which is a safety plus on the road.
• Best fast charging for a workout → Horett Headphone Neckband Lightweight. A full charge takes about 1 hour, so a quick top-up before a session is realistic.
• Best for a long night of continuous play → Ertuly Sleep Earbuds. Up to 6 hours per charge and up to 30 hours with the case covers overnight and beyond.
• Best for sensitive ears during extended wear → Ertuly Sleep Earbuds. The soft, smooth, skin-friendly materials are chosen specifically for long sessions.
• Best for people who lose earbuds easily → Horett Headphone Neckband Lightweight. A neckband can't roll under a treadmill.
In my opinion, this comes down to what "ultra lightweight" needs to do for you. For workout use — running, cycling, lifting, anything where you're moving and want your ears open — I would buy the Horett Headphone Neckband Lightweight. The stable neckband, the air conduction bass without ear insertion, and the roughly 1-hour full charge all line up with training rather than sitting still. If your priority is sleep instead, the Ertuly Sleep Earbuds are the better buy, because 3 grams per bud and a side-sleeper shape solve a problem the Horett simply wasn't designed for. Pick the job first, then the product.
For workouts, I'd point to the Horett Headphone Neckband Lightweight. Its sports neckband is designed for running, cycling and gym sessions, and the open-ear air conduction design keeps you aware of your surroundings. The Ertuly is a sleep-first earbud, not a training product.
That's exactly what they're shaped for. Ertuly describes them as ergonomically formed to sit snugly without pressure and to stay in place for side sleepers, with soft skin-friendly materials for extended wear. If you've had earbuds dig into your ear on a pillow, this is the design aimed at that.
The data sheet describes a sport-friendly neckband built for running, cycling and gym workouts, but it does not list a water-resistance rating, so I can't claim a specific IP level. If you need waterproof earphones for workout sessions in heavy sweat or rain, treat that as an open question and check the product details before buying.
They're quoted differently. The Horett charges fully in about 1 hour and is built for long listening and call sessions on a 50mAh LiPo battery with low-power tech. The Ertuly offers up to 6 hours of continuous playtime and up to 30 hours total with its charging case. For overnight use, the Ertuly's case setup is the more relevant figure.
