How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a fully in-ear, noise-cancelling pair with a transparency mode for tuning out a noisy bedroom, choose ZIPFORCE True; if you need an open-ear design that never plugs your ear canal and lets you hear the room while you drift off, choose PTHTECHUS Open Ear Headphones. For sleeping specifically, the two solve the same problem in opposite ways — one seals sound in, the other keeps you aware of it — so the right pick comes down to how you rest, not which one is "better."
• ZIPFORCE True — biggest strength: Active Noise Cancellation with three modes (ANC On, ANC Off, Transparency) plus 4-mic ENC call reduction that suppresses up to 80% of background noise on calls.
• ZIPFORCE True — biggest trade-off: It's a fully in-ear design (45-degree angled, 4.7g per bud), so anyone who dislikes something seated in the ear canal will feel it.
• PTHTECHUS Open Ear Headphones — biggest strength: A completely open design that sits above the auricle, stays breathable for long wear, and plays nicely with glasses.
• PTHTECHUS Open Ear Headphones — biggest trade-off: Open-ear means no active noise cancelling — you hear your surroundings by design, and there's no sealed bass or passive isolation.
• Who each pick is for: ZIPFORCE True for buyers who want quiet, private, call-focused listening; PTHTECHUS for buyers who want awareness, breathability and all-day comfort.
The ZIPFORCE True is built around control over what you hear. Its headline feature is smart Active Noise Cancellation that adapts to your environment, with three selectable modes: ANC On, ANC Off and Transparency for passing outside sound through. If you sleep next to a road, a snoring partner or a humming appliance, that's the lever you'll actually use — flip to ANC On to blunt the drone, or Transparency when you want to stay aware of a baby monitor or an alarm.
The second thing it does well is calls. Each earbud carries two microphones, and the ENC noise-reduction system is designed to suppress roughly 80% of interfering background noise while lifting the human voice, so the person on the other end hears you rather than your room. For anyone who takes a call before lights-out, or who needs a clear-sounding headset first thing in the morning, that's a meaningful design choice rather than a marketing line. Bluetooth 5.3 keeps latency low (under 65ms per the specs) and reconnects automatically once paired.
On battery, ZIPFORCE quotes 40 hours total with the charging case and about 4.5 hours of average life per charge, with a 30-minute charge giving roughly 5 hours of use. The buds themselves are 4.7g each with a 45-degree angled in-ear shape, and the case is pocket-sized. IPX5 waterproofing covers sweat and light splashes.
Who should buy it: side and back sleepers who want to mute a noisy room, people who lean on clear voice calls, and anyone who prefers the secure, tucked-in feel of an in-ear bud. Who should skip it: anyone who finds in-ear tips uncomfortable over long stretches, or who wants to stay fully aware of their surroundings while lying in the dark. If you're shopping for a comfortable kids headset for sleeping, note that this is an in-ear design — some children dislike that feeling, so the open-ear shape may suit them better.
The PTHTECHUS Open Ear Headphones take the opposite approach. Instead of sealing your ear, the earbuds rest gently and firmly above the auricle in a fully open design. That means air moves, pressure doesn't build, and the spec sheet's claim of comfort over long wear makes structural sense. The buds are 4.8g each and the enclosure combines metal, plastic and silicone, which suggests a lightweight frame rather than a bulky one. It's also explicitly pitched as fitting well alongside glasses — a genuine plus if you wear them to bed or read before sleep.
Sound-wise, the driver is a dynamic unit covering 20Hz to 20,000Hz, paired with directional sound technology intended to minimize leakage so your audio stays private even with an open fit. ENC noise reduction handles calls, and PTHTECHUS specifically claims clear calls in windy conditions — useful if you take a call on a walk or a balcony. Bluetooth 5.4 is the newer version here, with a 10-meter range and auto-connect once the case opens.
Who should buy it: hot sleepers, glasses wearers, side sleepers who can't stand pressure in the ear canal, and anyone who wants to hear a smoke alarm, a child or a partner while falling asleep. Who should skip it: buyers who want real noise blocking. Open-ear is the whole point, and it's the opposite of isolation. If you need a rotatable ear cups earbuds for sleeping feel — something you can angle and tuck without canal pressure — this open, above-the-ear placement is the closest match in this pair.
Side-by-Side: Which Should You Choose?
• Best for noise blocking while sleeping → ZIPFORCE True. Three-mode ANC is the only real isolation in this comparison.
• Best for pressure-free, all-night comfort → PTHTECHUS Open Ear Headphones. Open design, 4.8g buds, breathable and glasses-friendly.
• Best for crystal-clear calls → ZIPFORCE True. Four microphones with ENC targeting up to 80% background-noise suppression.
• Best for staying aware of your surroundings → PTHTECHUS. Nothing seals your ear, so alarms and voices come through.
• Best for battery per charge → PTHTECHUS. Up to 8 hours on a single charge versus roughly 4.5 hours for ZIPFORCE.
• Best for quick top-ups → PTHTECHUS. A 15-minute charge returns about 3 hours; ZIPFORCE needs 30 minutes for about 5.
• Best for the newest Bluetooth → PTHTECHUS. Bluetooth 5.4 versus 5.3 — a small generational step.
• Best for private, sealed listening → ZIPFORCE True. In-ear tips plus ANC keep your audio in and the room out.
For sleeping, I'd buy the PTHTECHUS Open Ear Headphones. In my opinion, the open, above-the-ear fit is the better match for a night of rest: no canal pressure, no heat build-up, and you stay aware of the room, which matters more to me at 2 a.m. than bass depth. The longer per-charge battery and faster top-up seal it. I'd only switch to the ZIPFORCE True if blocking noise is your priority — a loud street, a snoring partner, or a need for the clearest possible calls. In that case its ANC and 4-mic ENC make it the smarter pick. Either way, check the current price on Amazon before deciding.
