• Raycon Essential Open Ear — biggest strength: an open-ear, hook-style fit that's featherlight and sweat-resistant, so you keep full awareness of your surroundings while moving.
• Raycon Essential Open Ear — biggest trade-off: no noise control at all, so loud environments stay loud, and the open design trades isolation for safety.
• Monster Persona 4th — biggest strength: hybrid active noise cancellation that Monster says cuts up to 90% of ambient noise, plus a 70-hour battery and three listening modes.
• Monster Persona 4th — biggest trade-off: it's a full over-ear headphone with 40mm drivers and a foldable frame, so it's bulkier and more of a deliberate wear than a tucked-away pair of buds.
• Who each pick is for: Raycon for runners, cyclists and people who need to hear the world; Monster for commuters, flyers and anyone who wants to block it out.
The Raycon Essential Open Ear is built around one idea: don't seal the ear. Instead of plugging your canal, it hangs behind your ear on a comfort hook and fires sound at you from the outside. That single design choice explains almost everything else about it. You hear your music and you hear the car behind you on the bike lane, the gym announcement, the colleague who walks up to your desk. For running headphones specifically, that's the whole point.
The fit is the other half of the story. Raycon describes these as incredibly lightweight with an ear-hugging design, and the specs back up the "light" part — the earbuds themselves weigh 0.14 kg as a package item, and the whole thing is pocket-sized plastic and silicone in a mint finish. You place the hook behind your ear, adjust the bud, and go. Sweat-resistant construction means gym sessions, cycling and everyday activity are fair game. Battery is rated at 36 hours with a case, and a full charge takes about an hour. Bluetooth 6 keeps the connection modern, touch controls handle playback, and the frequency range runs the standard 20–20000Hz. It ships with a one-year warranty.
Who should buy it: runners, cyclists, walkers, gym-goers, delivery riders, office workers who need to stay reachable, and anyone who finds sealed earbuds uncomfortable after an hour. Who should skip it: if you fly often, work in a loud open office, or commute on a screeching subway and want the noise gone, this is the wrong tool. There's no noise cancellation here — noise control is listed as "None." That's not a flaw, it's the trade-off you're accepting for awareness.
The Monster Persona 4th goes the opposite direction. These are over-ear headphones with square-shaped ear cups, memory-protein foam padding and an adjustable metal headband, and the entire pitch is immersion. Hybrid active noise cancellation is the headline feature — Monster rates it as reducing up to 90% of ambient noise, with the emphasis on mid-to-low frequencies like car and airplane rumble. If your daily audio life happens on a plane, a train or a busy street, that's exactly the noise profile you want gone.
Then there's the battery. 70 hours of playtime is a genuinely long runway, and the rapid-charge claim is the practical part: a 10-minute top-up is rated for about 5 hours of playback. A full charge takes roughly 2 hours. That combination means you can leave the cable at home for a week-long trip and not think about it.
Sound is handled by custom 40mm dynamic drivers tuned for what Monster calls Pure Monster Sound — crisp highs, balanced mids and punchy bass. You also get three modes: Standard for everyday listening, Noise-canceling for noisy environments, and Transparency when you want to hear what's happening around you without taking the headphones off. Controls are physical push buttons rather than touch, which is a real plus with gloves on or in cold weather. There's a 3.5mm jack for wired listening, Bluetooth 6, a 33-foot wireless range, a foldable frame for storage, and a one-year warranty.
Who should buy it: frequent flyers, train commuters, remote workers in noisy homes, bass-forward listeners, and anyone who wants one pair of headphones to last a full week of listening. Who should skip it: runners and cyclists. Over-ear headphones with a headband are not what you want bouncing on your head at mile three, and with ANC on you're deliberately cutting yourself off from traffic.

• Best for long-haul travel and flights → Monster Persona 4th. ANC, over-ear padding and a foldable frame for a carry-on.
• Best for all-day comfort in a hot gym → Raycon Essential Open Ear. Lightweight, sweat-resistant and no ear cups pressing on your head.

In my opinion, most people should start by asking what their ears actually need to do. If your listening happens while your legs are moving and your surroundings matter, I'd buy the Raycon Essential Open Ear — the open-ear hook design, the light weight and the sweat resistance are exactly right for that life, and 36 hours is plenty. If your listening happens while you're sitting still and the world is too loud, I'd buy the Monster Persona 4th — ANC, 70 hours and over-ear comfort are the better answer there. They're not really competitors so much as two different jobs. Pick the job you actually have.
Yes — that's its core use case. The ear-hugging hook keeps it secure during movement, it's sweat-resistant, and the open design lets you hear traffic and surroundings while you run.
Yes. It uses hybrid active noise cancellation that Monster rates as reducing up to 90% of ambient noise, mainly mid-to-low frequencies like cars and airplane engines. It also has a Transparency mode when you want awareness instead.
The Monster Persona 4th, clearly. It's rated for 70 hours of playtime versus 36 hours for the Raycon Essential Open Ear, and a 10-minute charge is rated for about 5 hours of playback.
You can, but I wouldn't recommend it for running or cycling. Over-ear headphones with a headband move around during intense activity, and ANC works against the awareness you want outdoors. The Raycon is the better gym and road pick.
