If you want warm ears and music in one piece of winter gear, choose Agkey Music Hat Beanie; if you need open-ear awareness for running, cycling and sweaty workouts, choose Purity Air Open Ear. Those are two genuinely different jobs, and picking the wrong one is the whole reason this comparison exists. One is a hat that happens to play audio. The other is an audio device that happens to sit near your ears without blocking them.
• Agkey Music Hat Beanie — biggest strength: it merges warmth and wireless audio into one item, so you never carry or lose a separate pair of earbuds in cold weather. Double-knit acrylic, a waterproof build, and a fully washable design with removable speakers make it a real winter hat first.
• Agkey Music Hat Beanie — biggest trade-off: sound is secondary to warmth. The speakers sit in pouches against your ears rather than sealing them, so this is fine for podcasts, calls and casual listening, not for critical music or blocking out the world.
• Purity Air Open Ear — biggest strength: open-ear awareness. You hear traffic, training partners and your surroundings while 15 mm drivers push sound in, with IPX5 sweat resistance and dual mics for calls.
• Purity Air Open Ear — biggest trade-off: it does nothing for cold. It's a neckband that leaves your head and ears exposed, and its non-sealed design also lets outside noise in by intention.
• Who each is for: Agkey for winter commuters, skiers, dog walkers and anyone who wants one warm thing that also plays music. Purity for runners, cyclists and gym-goers who need to stay aware and don't mind a bare head.
The Agkey Music Hat Beanie is a winter hat with a wireless headset built in. The speakers live in small pouches in the brim, and a control panel on the edge of the beanie handles volume, play/pause, track skipping, answering and hanging up calls, and redialing — all through three buttons you can find by feel with gloves on. The upgraded chip gives you Bluetooth 5.0 with a stated range up to 33 feet and a stable connection to iOS, Android and Samsung phones. There's a noise-cancelling mic to cut down wind and background noise on calls, a Micro USB charging port with the cable included, and a little pocket in the brim to stash the headset when you're not using it.
Who should buy it: skiers, snowboarders, joggers in cold months, people walking dogs, commuters waiting on platforms, and anyone who keeps losing earbuds in coat pockets. It's also a straightforward gift for family and friends in fall and winter. Who should skip it: if you want serious audio quality, in-ear isolation, or you live somewhere without a real winter, this isn't the tool. It's also not the right pick if you hate the feel of a beanie over your ears — the fit is snug by design, since the speakers need to sit close to your ears to be heard.
Purity Air Open Ear: Who It's For
The Purity Air Open Ear Headphones are a neckband-style open-ear set. You hang them behind your neck with the two speakers resting against your ears rather than inside them, and sound is delivered by air conduction — the drivers push audio toward your ear canal without plugging it. Two 15 mm drivers handle the sound, with a frequency range of 20 Hz to 20,000 Hz and 18 ohm impedance, which is the kind of spec that usually means easy to drive from a phone. Bluetooth 5.3 with a 10-meter range keeps the connection current, and the whole thing weighs 2.8 ounces.
The pitch here is awareness plus comfort. Because nothing seals your ear, you stay tuned into traffic, other runners, and gym surroundings — exactly what you want on a road run or a bike ride. IPX5 water resistance covers sweat and light rain, so long workouts won't kill them. Dual microphones handle environmental noise cancellation on calls, so your voice comes through over background sound. Controls are a mix of touch and buttons, focused on call control. Charging is magnetic — you attach the cable to contacts on the right speaker, and the LED goes red while charging and blue when full. The battery is rated around 6 hours per charge.
Who should buy it: runners, cyclists, hikers, gym regulars and outdoor workers who need to hear what's happening around them. It's also a good fit for anyone who finds in-ear buds uncomfortable after an hour. Who should skip it: if you want passive noise blocking on a plane or a loud train, open-ear is the wrong category by design — it lets sound in on purpose. And if you're buying for winter, this does nothing for cold ears.
• Best for cold-weather use → Agkey Music Hat Beanie. It's a heavyweight, waterproof, double-lined winter hat that also plays audio.
• Best for hot-weather and sweaty workouts → Purity Air Open Ear. IPX5 sweat resistance and an open design beat a knit beanie in July.
• Best for staying aware of traffic → Purity Air Open Ear, though the Agkey hat also leaves your ears unsealed, so both let sound in.
• Best for hands-free calls with a hat on → Agkey Music Hat Beanie. Three physical buttons plus a noise-cancelling mic, all reachable with gloves.
• Best for longest listening between charges → Purity Air Open Ear. About 6 hours rated, versus a hat you'd mostly use in shorter outdoor bursts.
• Best for washing → Agkey Music Hat Beanie. Pull the speakers out and the hat itself is machine-washable.
• Best for wearing for hours without thinking about it → Purity Air Open Ear. At 2.8 ounces with a neckband, it's built for long sessions.
• Best for a gift in winter → Agkey Music Hat Beanie. It's a hat first, so it works even if the person never pairs it.
In my opinion, the deciding question is what season you're shopping for. If you want one item that keeps your head warm and plays music on a ski slope, a dog walk or a cold commute, I'd buy the Agkey Music Hat Beanie — the washable design, the glove-friendly three-button panel and the waterproof build make it a genuinely practical winter hat rather than a gadget. If you're a runner, cyclist or gym-goer who needs to hear the world while you train, I'd buy the Purity Air Open Ear instead, because the open-ear design, IPX5 rating and 6-hour battery are built for exactly that. Neither replaces the other. Buy for the weather and the activity, not the spec sheet.
FAQ
No — that's the point. Open-ear air conduction deliberately lets ambient sound in so you stay aware of your surroundings. It has active noise cancellation and dual mics for calls, but it is not designed to seal out the world for listening.
Yes. You remove the headset speaker drivers from their pouches first, then wash the hat. Reinstall the speakers afterward. The hat itself is knit acrylic and rated waterproof.
Pick by season and activity. Cold weather and general outdoor use, including calls with gloves on, point to the Agkey hat. Running, cycling or the gym in any weather points to the Purity Air Open Ear. Check the current price on Amazon before deciding, since value is the one thing specs can't tell you.
