If you want marathon battery life, a charging case that doubles as an emergency power bank, and punchy bass for gym sessions, choose hadbleng Ear buds; if you need an open-ear design that keeps you aware of traffic and lets you run two devices at once for calls and meetings, choose NOUUI Open Ear Headphones.
• hadbleng's biggest strength: an enormous power story — a 2600 mAh case rated for up to 128 hours of playback that can also top up your phone or tablet in a pinch.
• hadbleng's biggest trade-off: it's a traditional in-ear design with earhooks, so it seals off your ear canal and you stay less aware of what's happening around you.
• NOUUI's biggest strength: open-ear comfort and awareness — 29 grams total, bone conduction drivers that leave your ear canal open, and dual-device Bluetooth so your phone and laptop stay connected together.
• NOUUI's biggest trade-off: no charging case, no listed playtime figure, and a sound profile built around calls and ambient awareness rather than deep bass.
• Pick hadbleng if you live in the gym, run outdoors, and want to go weeks between charges.
• Pick NOUUI if you're on calls all day, wear glasses or a helmet, and hate things stuffed in your ears.
The Q22 is built around one idea: never let the battery run out. The earbuds themselves are rated for 8 hours per charge, and the case pushes that to a claimed 120 hours of music playback, with the case itself listed at 128 hours of carrying-case battery life. A dual LED display on the case shows both the case's remaining power and each earbud's charging status, so you're never guessing whether you grabbed a dead pair on the way out the door. Two hours of charging gets everything back to full.
On the audio side, hadbleng uses 13 mm dual-layer graphene diaphragm drivers with a bass-enhancement algorithm, and the brand explicitly markets "powerful bass." Call quality leans on hybrid ENC noise cancellation with a microphone that hadbleng says passively cuts roughly 90% of background noise. The Bluetooth 5.3 chip is advertised with an 85% improvement in audio transfer speed, up to 15 meters of range, and one-step auto-pairing once you've connected the first time. Smart touch controls handle track skipping, volume, calls and a voice assistant — Siri is named as the control type.
For fit, these are over-ear hooks at 6 grams per bud, with three sizes of silicone tips included. IP7 waterproofing covers splashes, rain and sweat. The case is the sleeper feature: at 2600 mAh it can charge a phone by more than 30% when fully charged, which is a genuinely useful trick on a long day out.
Buy the hadbleng if: you train hard, sweat a lot, want bass-forward sound, and value not thinking about a charger for days at a time.
Skip it if: you need to hear traffic, coworkers or announcements while listening, or if you dislike anything sitting inside your ear canal. It's also worth checking the current price on Amazon, since that's the deciding factor for a lot of buyers at this tier.
The NOUUI headset solves the opposite problem. Instead of sealing your ears, it sits along the outer edge of your ear and uses bone conduction drivers rated 20 Hz – 20,000 Hz at 140 ohm impedance. Your ear canal stays open, so you hear music and your surroundings at the same time. NOUUI calls this out directly for jogging, cycling and driving — exactly the situations where blocking your ears is a bad idea.
Weight is the headline number: 29 grams for the whole headset. That's light enough that NOUUI markets it for all-day wear, including under a helmet or alongside glasses, with skin-friendly silicone pads and an ergonomic curve that's meant to hold without constant adjusting. The brand also cites 5,000 bend tests on the frame for durability, and the micro-frosted surface is there to resist smudges.
The work-from-home angle is where this thing is strongest. Bluetooth 5.3 with dual connection means you can pair your phone and laptop simultaneously and switch between them without repairing — take a call while a video meeting is running, then jump back. Range is listed up to 14 meters. The microphone rotates 270° so you can aim it at your mouth, and an AI noise-cancelling mic filters background noise in offices, gyms and streets. There's a dedicated mute button, which matters more than people admit during meetings. Controls are push-button via a multifunction button rather than touch, which is less fiddly with gloves or sweaty hands.
One note: the spec sheet lists "Active Noise Cancellation" for noise control, but given the open-ear design, treat that as microphone-side noise cancellation for your voice on calls — not the kind of isolation that blocks out the world. The open design is the whole point here.
Buy the NOUUI if: you take a lot of calls, work across two devices, run or cycle outdoors, or simply can't tolerate in-ear buds.
Side-by-Side: Which Should You Choose?
• Best for battery life → hadbleng Ear buds. Up to 128 hours with the case versus no published figure for NOUUI.
• Best for call and meeting work → NOUUI Open Ear Headphones. Rotating mic, AI noise cancelling, mute button, dual-device connection.
• Best for bass and music immersion → hadbleng Ear buds. 13 mm graphene drivers with a bass-enhancement algorithm and hybrid noise cancellation.
• Best for situational awareness → NOUUI Open Ear Headphones. Open-ear bone conduction keeps traffic, gym announcements and coworkers audible.
• Best for long wear and glasses/helmet users → NOUUI Open Ear Headphones. 29 grams total, open fit, silicone pads.
• Best for gym, running and rain → hadbleng Ear buds. IP7 waterproofing, 6-gram earhook fit, three tip sizes.
• Best for travel and emergencies → hadbleng Ear buds. The 2600 mAh case can top up your phone by more than 30%.
• Best for multi-device switching → NOUUI Open Ear Headphones. Connect phone and laptop at once with Bluetooth 5.3.
If I had to pick one for myself, I'd take the NOUUI Open Ear Headphones — in my opinion, the open-ear design plus dual-device Bluetooth and the 270° rotating mic covers more of my actual day, since calls and awareness matter more to me than bass. That said, if your priority is music quality, sweat-proof sport use, and going a week or more without charging, the hadbleng Ear buds is the smarter buy and the one I'd recommend for gym-focused buyers. Neither is objectively better; they solve different problems. Check the current price on Amazon before you commit, and let your own routine decide.
FAQ
The spec sheet lists Active Noise Cancellation, but since the design is open-ear, expect that to apply mainly to the AI microphone filtering background noise on your calls — not to blocking sound from reaching your ears. If you want isolation while listening, the hadbleng's hybrid noise cancellation is the closer match.
The NOUUI. It has a 270° rotating microphone, an AI noise-cancelling mic, a dedicated mute button, and dual connection so you can take a call on your phone without dropping your laptop.
The earbuds are rated 8 hours per charge, the case adds up to 120 hours of music playback, and the case itself is listed at 128 hours of carrying-case battery life. Charging takes about 2 hours. NOUUI does not publish a playtime figure, so that's a point in hadbleng's favor if endurance matters most.
