How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the pair that keeps a full workday of Zoom calls, music and travel going on one charge with real noise cancellation, choose Cubitt Tracking Technologies Power Headphones; if you need something so small it disappears in your ear for side-sleeping and waterproof wear, choose Piegricdiat Invisible Sleep Headphones. They solve two completely different problems. One is a work-and-travel headset for zoom calls; the other is a sleep-first micro earbud.
• Cubitt's biggest strength: up to 60 hours of battery life, Hybrid ANC with three sound modes, and 4 microphones with noise reduction for clear voice on calls.
• Cubitt's biggest trade-off: it is a full over-ear, wireless-only headphone with no jack — bulky next to a micro earbud, and not designed for sleeping on your side.
• Piegricdiat's biggest strength: an in-ear design small enough to sit discreetly and comfortably all night, with IPX6 waterproofing and a sleep mode that disables the buttons.
• Piegricdiat's biggest trade-off: roughly 8 hours of battery life and a 1-hour charge time, so it needs recharging far more often than the Cubitt pair.
• Pick Cubitt if you want one durable headset for calls, work and long listening sessions.
• Pick Piegricdiat if you want invisible earbuds for sleep, side-sleeping and water sports.
This is the pair I would hand to anyone whose day revolves around talking. The spec that matters most is the microphone setup: 4 microphones paired with advanced noise reduction, which is exactly what you want when you are the one being heard on a call rather than the one listening. If you have ever been the person on a Zoom call who sounds like they are broadcasting from a wind tunnel, that is the design problem this headphone is built to fix. Combined with Hybrid Active Noise Cancellation and three modes — ANC On, ANC Off and Transparency — you can shut out a noisy room or let it back in when you need to hear someone at the door.
Who should buy it: remote workers, students, commuters and frequent flyers who want one solid, long-lasting headset for calls and media. Who should skip it: side sleepers, swimmers and anyone who wants earbuds that vanish into the ear — this is a full-size over-ear with no wired option, so it is the wrong tool for those jobs.
Piegricdiat Invisible Sleep Headphones: Who It's For
The Piegricdiat pair is built around a very specific comfort problem: wearing something in your ears for eight hours straight without pain. The design uses skin-soft silicone eartips and caps, and the buds are small enough to sit discreetly — the brand's pitch is that you can hide them at work or wear them through the night. For side sleepers, that matters more than any spec sheet number, because a normal earbud pressing into a pillow is the reason most people give up on sleep audio. Piegricdiat also includes a sleep mode where every button is disabled and you control playback only from your phone, which prevents accidental touches when you roll over.
Durability here is aimed at water rather than the office. IPX6 waterproofing supports swimming, surfing and snorkeling, and the earbuds are rated for more than 6 hours of continuous underwater use. Bluetooth 5.3 gives a stable, low-latency connection, and the brand claims 3D surround sound with a built-in noise reduction microphone for calls. The honest limitation is stamina: average battery life is about 8 hours with a 1-hour charge time, so this is a nightly-charge product, not a weekly one.
Who should buy it: side sleepers, light sleepers who want masking audio, swimmers and anyone who needs earbuds that stay hidden. Who should skip it: people who need all-day battery and serious active noise cancellation for work calls — that is not what this bud is for.
Side-by-Side: Which Should You Choose?
• Best for clear calls and meetings → Cubitt Tracking Technologies Power Headphones (4 microphones with noise reduction, Bluetooth 5.4).
• Best for blocking out a noisy room → Cubitt Tracking Technologies Power Headphones (Hybrid ANC with ANC On, ANC Off and Transparency modes).
• Best for side sleepers → Piegricdiat Invisible Sleep Headphones (in-ear, skin-soft silicone tips designed to stay comfortable overnight).
• Best for swimming and water sports → Piegricdiat Invisible Sleep Headphones (IPX6 waterproof, rated for 6+ hours underwater).
• Best for discreet, invisible wear → Piegricdiat Invisible Sleep Headphones (small buds plus a sleep mode that locks the buttons).
• Best for travel and commuting → Cubitt Tracking Technologies Power Headphones (foldable, stainless steel over-ear build with fast USB-C charging).
• Best for quick top-ups → Piegricdiat Invisible Sleep Headphones (about 1 hour to full charge), as long as you accept the shorter runtime.
I would buy the Cubitt Tracking Technologies Power Headphones. For a headset that has to survive a working week — zoom calls in the morning, music on the commute, a film on a flight — 60 hours of battery, Hybrid ANC and a 4-microphone array is the combination that actually holds up, and the stainless steel over-ear build and foldable frame point to a product meant to last. The Piegricdiat buds are genuinely clever at what they do, but 8 hours of runtime makes them a specialist sleep and swim tool, not a daily driver. In my opinion, if your priority is durable, long-lasting headphones for calls first and everything else second, Cubitt is the one. If you sleep on your side and want nothing poking your ear, get the Piegricdiat instead.
FAQ
In my opinion, the Cubitt Tracking Technologies Power Headphones are the stronger pick of these two for long sessions, because they are rated at up to 60 hours of average battery life versus about 8 hours for the Piegricdiat buds. Longevity also comes down to build — the Cubitt pair uses a foldable over-ear design with a stainless steel enclosure and fast USB-C charging.
Based on the specs here, the Cubitt Power Headphones last longest, running Bluetooth 5.4 with up to 60 hours of battery. The Piegricdiat buds use Bluetooth 5.3 with about 8 hours of playback and a 1-hour charge time.
The Cubitt pair is the one built for that: 4 microphones with advanced noise reduction, Hybrid ANC and a Transparency mode so you can hear your own voice and the room. The Piegricdiat buds include a noise reduction microphone too, but their short battery life and sleep-first design make them a secondary choice for back-to-back meetings.
