If you want a slim on-ear headset built for clear, private conversation on video calls, choose Plantronics 78712-101; if you need a wearable sleep and sports headband that plays music wirelessly and takes calls hands-free, choose MUSICOZY Sleep Headphones. These two live in completely different worlds, which is exactly why the comparison is useful. One is a wired, over-ear office headset engineered around the human voice. The other is a Bluetooth fabric headband that happens to contain tiny speakers. Here's how I'd decide between them, especially for video calls.
• Plantronics 78712-101 — biggest strength: a slim, satin-finish over-ear design with leatherette ear pads, a telescoping noise-cancelling boom mic and a 6,800 Hz frequency response tuned for speech clarity.
• Plantronics 78712-101 — biggest trade-off: it's a wired headset with a Quick Disconnect plug, listed as not USB compatible, so it's tethered to a desk setup rather than something you walk around with.
• MUSICOZY Sleep Headphones — biggest strength: a stretchy, breathable fabric headband with 40mm drivers, Bluetooth 5.4, a built-in mic and up to 14 hours of playtime on a 1–2 hour charge.
• MUSICOZY Sleep Headphones — biggest trade-off: it's in-ear/on-head fabric audio with sound isolation rather than active noise cancellation, and it's designed for comfort during sleep and workouts, not for all-day office talk.
• Who each pick is for: the Plantronics is for the desk-bound professional who lives in calls; the MUSICOZY is for the sleeper, traveller, jogger or side-sleeper who wants music without anything pressing into their ears.
The Plantronics 78712-101 is a purpose-built communication headset from the EncorePRO 710/720 line. The design language is deliberate: a slim, stylish over-ear frame with an elegant satin finish and premium nylon composite materials that keep the whole thing light — the item weight is listed at 1.9 ounces. The leatherette ear pads and adjustable fit are there to make long shifts bearable, which tells you who this was built for: someone wearing a headset for hours, not minutes.
The audio side backs that up. The frequency response tops out at 6,800 Hz, which is narrower than a music-first headphone and exactly what you want for voice — speech intelligibility lives in that range. The curved, telescoping microphone and pivoting boom are designed to sit close to the mouth while staying clear of your peripheral vision, and active noise cancellation plus sound isolation help keep your side of the call clean. The Quick Disconnect feature is the giveaway detail: it lets you unplug and walk away without taking the headset off, and it's compatible with Plantronics USB and deskphone cabling.
Who should buy it? If your day is back-to-back video calls, a slim on-ear headset with a boom mic that keeps your voice private is the right tool. I'd recommend it for anyone who wants the best headset for video calls in a fixed desk setup. Who should skip it? If you wanted wireless freedom, in-ear buds, or something to wear to bed, this isn't it — it's wired, it's not USB compatible as listed, and it's a headset, not a lifestyle audio device.
The MUSICOZY Sleep Headphones are a 2-in-1 sleep and sports headband. Instead of ear cups, you get an elastic, breathable band with ultra-thin stereo speakers inside, built from durable braided cord, a high-elastic lining and a sweat-absorbent finish. The idea is simple: music without anything jammed into your ear canal, and without a band that digs in when you roll over.
The tech inside is modern for its category. Bluetooth 5.4 handles the wireless connection, and 40mm composite drivers push what the sheet describes as loud, balanced output with rich bass, a clear midrange and balanced treble. There's a built-in microphone so you don't miss calls, and the battery is rated for up to 14 hours of continuous playtime from a 1–2 hour charge, with the battery itself described as lasting up to a year. Noise control is sound isolation rather than active cancellation.
Who should buy it? Side sleepers, travellers, gym-goers, joggers and anyone who wants background music or a podcast without earbuds pressing into their ears. The built-in mic makes it usable for casual calls too. Who should skip it? If your priority is a professional-grade microphone for meetings, or active noise cancellation for a noisy open office, the fabric-band format isn't built for that. It's also an in-ear/earbud-style listening experience by classification, so if you specifically want a slim on-ear headset, this is a different animal.
Side-by-Side: Which Should You Choose?
• Best for voice clarity on calls → Plantronics 78712-101. A telescoping noise-cancelling boom mic and a 6,800 Hz voice-tuned response are made for talking, not just listening.
• Best for all-day desk comfort → Plantronics 78712-101. Leatherette pads, an adjustable fit and a 1.9-ounce build are designed for long shifts.
• Best for wireless freedom → MUSICOZY Sleep Headphones. Bluetooth 5.4 with no cable at all.
• Best for sleep, travel and workouts → MUSICOZY Sleep Headphones. The breathable, sweat-absorbent headband format is the whole point.
• Best for walkaway convenience at a desk → Plantronics 78712-101. The Quick Disconnect lets you step away without removing the headset.
• Best for casual hands-free calls on the move → MUSICOZY Sleep Headphones. The built-in mic makes it usable, though it's not a broadcast-grade boom.
• Best for music-first listening → MUSICOZY Sleep Headphones. 40mm composite drivers with bass, midrange and treble tuning beat a voice-optimised headset for music.
In my opinion, the Plantronics 78712-101 is the one I'd buy if my goal is looking and sounding professional on video calls. The slim on-ear design, the pivoting noise-cancelling boom and the voice-tuned frequency response are all pointed at one job, and it does that job without drawing attention. I'd pick the MUSICOZY Sleep Headphones only if my real need is comfortable, cable-free listening for sleep, travel or workouts — and the built-in mic is a bonus, not the main event. For video calls specifically, I'd go Plantronics.
are on ear headphones good
Yes, for the right job. The Plantronics 78712-101 is a slim on-ear headset with leatherette pads and an adjustable fit, which makes it well suited to long stretches of talking. On-ear designs generally prioritise comfort and a compact footprint over deep isolation, so they suit office and call work more than immersive music listening.
are on ear headphones comfortable
Comfort depends on padding and weight. The Plantronics 78712-101 uses soft leatherette ear pads and lightweight nylon composite materials at 1.9 ounces, and its adjustable fit is designed for all-day wear. If you need something to sleep in, though, the MUSICOZY fabric headband is the more comfortable format because nothing presses into your ears.
are headphones less harmful than earphones
That's a volume-and-duration question more than a design one. In-ear models like the MUSICOZY sit inside the ear canal, while the Plantronics 78712-101 is an over-ear headset that rests outside it. Either way, keeping the level moderate and taking breaks matters more than the format itself — the data sheets don't make any health claims.
what are the best open ear headphones
Neither of these is an open-ear design. The Plantronics 78712-101 is an over-ear headset with active noise cancellation and sound isolation, and the MUSICOZY is an in-ear/earbud-style headband with sound isolation. If open-ear is your requirement, you'd need to look at a different category entirely.
