How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want active noise cancellation, memory foam comfort and marathon battery life for focused work, choose BYDGUMEI L90; if you need an open-ear clip design that keeps you aware of your surroundings while you take calls and move around, choose Aurotlu Open Ear Clip. That's the short version. The longer version matters if you're shopping for audiophiles-grade sound in an office setting, because these two products solve completely different problems.
• BYDGUMEI L90's biggest strength: hybrid active noise cancellation that filters up to 90% of low-frequency ambient sound, paired with memory foam ear cups and up to 50 hours of playback in ANC mode.
• BYDGUMEI L90's biggest trade-off: it's an over-ear headphone, so it physically covers your ears — you won't hear a coworker or a doorbell while ANC is on, and the ANC/AUX functions are incompatible with each other.
• Aurotlu Open Ear Clip's biggest strength: an open-ear clip design that never plugs the ear canal, plus IPX7 water resistance and a charging case that extends total playtime to roughly 60 hours.
• Aurotlu Open Ear Clip's biggest trade-off: no noise cancellation at all, and a shorter 12-hour single-charge runtime than the BYDGUMEI.
• Who the BYDGUMEI L90 is for: the buyer who wants to disappear into deep work, meetings and long listening sessions.
• Who the Aurotlu Open Ear Clip is for: the buyer who splits time between a desk, the street and the gym, and refuses to be sealed off from the room.
The L90 is built around one idea: keep the outside world out so you can keep your attention in. Its hybrid active noise cancellation uses a dual-noise-detection microphone setup that the spec sheet says filters up to 90% of low-frequency ambient sound — the hum of an HVAC unit, traffic rumble, the drone of an open-plan office. Three selectable modes (traffic, outdoor, indoor) let you nudge that filtering toward the environment you're actually sitting in. One thing to plan around: ANC and the AUX cable don't work at the same time, so if you want wired listening you're giving up noise cancellation for that session.
Sound-wise, the 40mm dynamic driver with a silk diaphragm is the headline. The spec sheet describes extended treble response up to 40kHz, which is the kind of figure that matters to listeners chasing detail and separation rather than just thump. If you're hunting for the best headset for audiophiles on a desk, this is the category the L90 is playing in — a large driver, a low 16-ohm impedance that makes it easy to drive, and touch controls for media.
Battery is where it genuinely pulls ahead: up to 50 hours with ANC running, up to 70 hours in standard mode, and a 5-minute charge that yields around 4 hours of listening. That's a headphone you can fly with, forget to charge, and still get through the week. Comfort comes from memory foam ear cups in an oval over-ear shape, and at roughly 9.28 ounces it's a light enough structure to wear through back-to-back meetings. There's also an AI call function for voice pickup, a 3.5mm jack for wired fallback, USB-C charging, and an 18-month warranty.
Aurotlu Open Ear Clip: Who It's For
The Aurotlu Open Ear Clip goes the opposite direction. Its ergonomic clip-on shape sits outside the ear canal entirely, so music plays while the room stays audible. The spec sheet frames this as the core benefit: hear external sounds clearly without giving up comfort, and no ear-canal pressure even after hours of wear. For an office, that's a real advantage — you catch your name across the room, you hear the elevator, you're not the person who misses a tap on the shoulder.
Connectivity is the newer standard here: Bluetooth 5.4, which the specs describe as faster, more stable transmission with ultra-low latency and tighter synchronization. In practice that's the version you want if you're pairing to a laptop and a phone and switching between them. Controls are touch-based, and the design supports multi-point.
Runtime is split across two numbers worth understanding. A single charge gives about 12 hours of continuous play, and the magnetic charging case adds roughly 48 more, for about 60 hours total. There's also an LED digital display on the case so you can see where you stand, and a full case recharge takes about an hour over Type-C. Standby is listed at up to 80 hours. That's plenty for a work week, though it's a case-dependent setup — the buds themselves don't run as long as the BYDGUMEI on a single charge.
Audio comes from 16.3mm dynamic drivers, which the sheet says reproduce instruments and vocals with enough nuance to catch subtle differences, plus voice capture for calls. And the IPX7 rating means sweat and rain aren't a problem — this is the one you can take from a spreadsheet to a run without changing gear. The warranty is shorter at 3 months, which is worth weighing.
Buy it if you want awareness, all-day comfort with nothing stuffed in your ear, and one pair that works at your desk and on the sidewalk. Skip it if you need to block out a loud office or a plane cabin — there's no noise cancellation here at all, and no wired jack as a backup.
• Best for blocking out a noisy office → BYDGUMEI L90. Up to 90% low-frequency filtering and three ANC modes.
• Best for staying aware of your surroundings → Aurotlu Open Ear Clip. Open-ear design that leaves the canal unobstructed.
• Best battery life between charges → BYDGUMEI L90. Up to 50 hours with ANC on, up to 70 in standard mode.
• Best total playtime with the case → Aurotlu Open Ear Clip. Roughly 12 hours per charge plus about 48 from the case.
• Best for detailed, high-resolution listening → BYDGUMEI L90. 40mm silk-diaphragm driver with treble extension up to 40kHz.
• Best for workouts and wet weather → Aurotlu Open Ear Clip. IPX7 sweat- and water-resistant.
• Best for long meetings without ear fatigue → Aurotlu Open Ear Clip. Nothing enters the ear canal, so there's no pressure build-up.
• Best for wired backup and travel gear → BYDGUMEI L90. 3.5mm jack, travel pouch, USB-C cable included, 18-month warranty.
• Best for newer Bluetooth and multi-device pairing → Aurotlu Open Ear Clip. Bluetooth 5.4 with multi-point support.
For an office-first buyer chasing audiophile-grade detail, I'd buy the BYDGUMEI L90. The combination of hybrid ANC, a 40mm silk-diaphragm driver, memory foam over-ear cups and up to 50 hours of ANC playback is exactly the package that makes focused work possible in a shared or noisy space — and the 18-month warranty is the longer of the two. I'd pick the Aurotlu Open Ear Clip only if awareness and open-ear comfort outrank isolation for you, or if you want one pair for both the desk and the trail.

how do over ear headphones work
Over-ear headphones rest around the ear rather than inside it, with a driver — here a 40mm dynamic driver — firing into a sealed cup. The BYDGUMEI L90 adds hybrid active noise cancellation, using dual microphones to detect and filter low-frequency ambient sound before it reaches your ear.
how long do over ear headphones last
That depends on build and battery, not a fixed number. In this comparison the BYDGUMEI L90 is rated for up to 50 hours of playback with noise cancellation on and up to 70 hours in standard mode, and it carries an 18-month warranty. The Aurotlu Open Ear Clip is rated for about 12 hours per charge with roughly 48 more from its case.
do over ear headphones damage hearing
Listening at high volume for long periods is the risk factor with any headphone, not the over-ear form itself. Notably, the Aurotlu Open Ear Clip's open design keeps your ear canal clear so you stay aware of your surroundings, while the BYDGUMEI L90's ANC lets you hear detail at lower volumes by removing background noise — which is generally the more sensible approach in a loud room.
what are the best over ear headphones
In my opinion, the best over-ear headphones for office work are the ones that combine real noise cancellation, a comfortable over-ear fit and long battery life — all three of which the BYDGUMEI L90 delivers with its ANC modes, memory foam cups and up to 50-hour runtime. If portability, waterproofing and open-ear awareness matter more to you, the Aurotlu Open Ear Clip is the better fit despite having no noise cancellation.
