How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want one pair of earmuffs-style headphones that doubles as hearing protection for loud, messy jobs, choose Qozybuds 6.0; if you need lightweight open-ear earbuds that stay put through sweat, runs and long workouts, choose Monster Open Ear AC336. They solve two totally different problems, so the real question is which problem is yours.
• Qozybuds 6.0 — biggest strength: On-ear hearing-protection design with a claimed 30dB SNR noise reduction, a huge 1200mAh battery rated for up to 120 hours of use, and oversized buttons you can press with work gloves on.
• Qozybuds 6.0 — biggest trade-off: It's a bulky on-ear muff that seals over your ears, so it's not something you'd wear casually at the gym or on a run, and it has no water-resistance rating listed.
• Monster Open Ear AC336 — biggest strength: True open-ear hook design that never plugs your ear canal, IPX6 water resistance, touch controls, app support, and a charging case rated for 21 hours total.
• Monster Open Ear AC336 — biggest trade-off: Playtime per charge is about 7 hours and noise control is listed as "None" — it lets the world in by design, so it's not for blocking out a lawn mower.
• Who each pick is for: Qozybuds 6.0 for mowing, woodworking, workshops and anyone who wants their ears covered and quiet; Monster Open Ear AC336 for runners, cyclists, hikers and gym-goers who want music without plugging their ears.
The Qozybuds 6.0 is built around a simple idea: cover your ears, cut the racket, and still get wireless audio. The on-ear enclosure is made from PVC in an orange finish, and the spec sheet lists a 30dB SNR noise reduction claim alongside active noise cancellation. That combination is what separates it from typical earbuds — you're getting physical coverage plus electronic quiet, which is exactly what you want when you're standing behind a mower or a table saw.
The numbers back up the "work outside all day" pitch. The battery is a 1200mAh cell rated for up to 120 hours of use, and a five-minute top-up is claimed to give you about four hours of music. Charging fully takes around two hours. It runs Bluetooth 6.0 for the wireless side, but there's also a 3.5mm jack, so you can go wired if you'd rather not deal with pairing at all. The 40mm drivers, 32-ohm impedance and 20KHz frequency response are ordinary on paper, but the point here isn't audiophile tuning — it's clear, loud-enough sound in a noisy environment.
The detail I like most is the control scheme. It uses large push buttons rather than touch surfaces, which the specs explicitly frame as glove-friendly for weeding, mowing, construction sites, studying and woodworking. It also supports Siri and Google Assistant for voice control. If you've ever tried to tap a touch-sensitive earbud with numb fingers in January, you understand why that matters.
Monster Open Ear AC336: Who It's For
The Monster Open Ear AC336 goes the opposite direction. Instead of covering your ears, it hooks over them. The earpiece shape is listed as "Hook," it's an open-ear fit, and the whole point is that nothing ever seals your ear canal. That means you keep awareness of traffic, other people and your surroundings while still hearing your music — which is precisely why open-ear designs have taken over the running and cycling world.
Monster packs real audio hardware in here: a dedicated digital audio processor, 13mm dynamic drivers, Qualcomm apt-X HD decoding, and a frequency range of 20Hz–20,000Hz. Bluetooth 6.0 gives you a stable connection rated up to 33 feet, plus auto power-on and pairing when you pull them from the case. The spec sheet mentions ENC (Environmental Noise Cancellation) too — but be clear on what that is: it cleans up your voice on calls, it does not silence the world around you. Noise control is listed as "None."
Battery life is the area where you need honest expectations. You get up to 7 hours per charge at 50–60% volume, and the case brings the total to 21 hours. USB-C fast charging gives you roughly an hour of playback from a 10-minute charge, and a full charge takes about two hours. For a daily run or a gym session, that's plenty. For a 12-hour shift, it isn't.
Durability is where it shines for active use. IPX6 water resistance means sweat and rain spray aren't a problem, and the shape-memory hardshell material is designed to hold its fit no matter how long you wear it. Controls are touch-based, with app support for customization. It ships in Deep Black with a black plastic case.
Who should buy it: runners, cyclists, hikers, lifters, and anyone who wants all-day comfort without pressure in their ears. Who should skip it: anyone who needs to block out loud machinery, or who prefers physical buttons over touch.
Side-by-Side: Which Should You Choose?
• Best for battery life → Qozybuds 6.0. Up to 120 hours of use from a 1200mAh battery versus 21 hours total from the AC336's case.
• Best for workouts and sweat → Monster Open Ear AC336. IPX6 water resistance and a secure hook fit are built for movement; the Qozybuds has no water rating listed.
• Best for wearing with gloves → Qozybuds 6.0. Large push buttons are explicitly designed for gloved hands. Touch controls on the AC336 are the opposite of glove-friendly.
• Best for situational awareness → Monster Open Ear AC336. The open-ear design keeps you tuned into traffic and surroundings — a safety feature for cyclists and runners.
• Best for all-day comfort → Monster Open Ear AC336. No ear-canal seal and a shape-memory hardshell mean nothing pressing into your ears for hours.
• Best for call clarity → Monster Open Ear AC336. ENC is designed to filter background noise out of your voice on calls, and apt-X HD helps audio quality.
• Best for wired backup → Qozybuds 6.0. It has a 3.5mm jack; the AC336 is wireless only.
If I had to pick one for myself, I'd take the Monster Open Ear AC336, because my listening happens on walks, bikes and around the house, and I value staying aware of my surroundings plus a fit I forget I'm wearing. The open-ear design, IPX6 rating and 21-hour case life cover that use case cleanly.
But if your listening happens next to loud machines — mowers, saws, job sites — I'd recommend the Qozybuds 6.0 without hesitation. In my opinion, the on-ear protection, 30dB SNR claim, 120-hour battery and glove-friendly buttons make it the obvious tool for that job. Check the current price on Amazon for both before you commit, since that's the one thing that can swing a close call.
Yes, in my opinion. The Qozybuds is designed as hearing protection with a 30dB SNR claim and covers your ears, while the Monster is open-ear with noise control listed as "None." For loud equipment, coverage wins.
The Qozybuds 6.0 by a wide margin — up to 120 hours of use from a 1200mAh battery, versus roughly 7 hours per charge and 21 hours total with the Monster's case. If you hate charging, that gap matters.
Yes. It carries an IPX6 water-resistance rating, which covers sweat and water spray, making it suitable for running, cycling and gym sessions. The Qozybuds has no listed water-resistance rating, so I'd keep it dry.
The Monster Open Ear AC336, based on the design specs. It uses an open-ear hook that avoids sealing the ear canal and a shape-memory hardshell for a consistent fit. The Qozybuds is an on-ear muff, which is comfortable for work but heavier and warmer over long stretches.
