If you want a warm, winter-ready knit headband that doubles as a Bluetooth beanie for cold-weather walks and bedtime listening, choose Fulext Sleep Headphones; if you need a lightweight, ultra-thin-speaker sleep mask built specifically for side sleepers and workouts, choose AONESY Sleep Headband Headphones.
• Fulext's biggest strength: It's a stretchy acrylic knit ear warmer with Bluetooth built in, so it keeps ears warm in cold weather while playing music, and it's backed by a 2-year warranty.
• Fulext's biggest trade-off: It's a bulky knit beanie-style headband (3.94 x 0.59 x 10.24 inches, 3.53 ounces) made of 100% acrylic, so it's warm rather than breathable and not designed as a slim sleep mask.
• AONESY's biggest strength: It's a lightweight fabric headband (2.4 ounces) with ultra-thin speakers explicitly positioned for side sleepers, plus it works for running, gym, travel and focus.
• AONESY's biggest trade-off: It's a single-purpose fabric headband with a 1-year warranty and no cold-weather insulation, so it won't keep your ears warm outdoors.
• Who Fulext is for: Anyone who wants a winter ear warmer that plays audio — commuters, dog walkers, campers, gift-givers.
• Who AONESY is for: Side sleepers, runners, gym-goers and travelers who want a thin, unobtrusive headband for audio at night or during workouts.
The Fulext Sleep Headphones are built around warmth first and audio second. The headband is made from stretchy 100% acrylic knit, which is the same kind of material you'd expect from a winter beanie — it's designed to keep your ears warm, block wind, and prevent that numb, frozen-ear feeling during cold months. Bluetooth is woven into that knit so you can pull the band down over your ears and listen to music, audiobooks or TV audio at the same time.
The connectivity is deliberately broad. Fulext lists universal Bluetooth with forward and backward compatibility, so it pairs with phones, tablets, laptops, PCs and most Bluetooth media players, with a stated range of around 33 feet. That range plus hands-free calling makes it more of an everyday wearable than a strict sleep accessory. The one-size stretch knit is meant to fit all head sizes and shapes, and the whole thing folds down small, which is why Fulext leans hard into the gift angle — stocking stuffers, holiday gifts, birthday gifts for women, men, teens, mom or dad.
Here's where I'd draw the line. Buy Fulext if your priority is a warm ear warmer with music built in — winter walks, camping, cold-weather commuting, costume parties, or just keeping your ears cozy while you listen in bed. Skip it if you sleep hot, sleep on your side and need something paper-thin against the pillow, or want a headband for sweaty gym sessions. The acrylic knit is warm by design, and at 3.53 ounces it's the heavier of these two. It also ships with 2 lithium-ion batteries included and carries a 2-year warranty, which is worth noting if longevity matters to you.
The AONESY Sleep Headband Headphones take the opposite approach: thin, light and purpose-built for lying down. The headline feature is ultra-thin speakers aimed squarely at side sleepers, paired with a sleep-mask function, so the idea is that you can wear it against a pillow without a hard speaker pressing into your ear. At 2.4 ounces it's noticeably lighter than the Fulext option, and it's made from fabric with an over-ear speaker placement.
AONESY positions this as more than a sleep product. The listing calls it a wireless music headband for running, gym, travel and focus — so it's meant to move with you during a workout and then stay on for a nap or a night's sleep. The dark gray fabric finish keeps it low-key, and it's sold as a single headband with wireless connectivity. Warranty coverage is 1 year from the manufacturer.
Who should buy it? In my opinion, AONESY is the better fit if you're a side sleeper who's been frustrated by earbuds digging in, or if you want one headband that handles both workouts and bedtime. It's also the smarter pick for travel and focus work because the thin profile is easy to forget you're wearing. Who should skip it? Anyone who wants warmth. There's no insulation here — it's fabric, not knit — so it won't do anything for cold ears on a winter walk. And if a longer warranty is a deciding factor for you, Fulext's 2-year coverage beats AONESY's 1 year.

If I had to pick one for myself, I'd buy the AONESY Sleep Headband Headphones — but only because my priority is sleeping on my side without a speaker jamming into my ear, and the ultra-thin-speaker design plus the 2.4-ounce fabric build is exactly what that problem calls for. That said, this is a genuine fork, not a landslide. If your real need is warm ears in winter with music attached, Fulext is the better product for you, and its 2-year warranty is a real point in its favor. Match the headband to your season and your sleep position, and you'll be happy either way.
FAQ
No — and that's not what they're for. AONESY is a fabric headband with a sleep-mask function, made for sleeping, running, gym and travel. For cold-weather ear warmth you'd want the acrylic knit construction of the Fulext headband instead.
Fulext states a 2-year warranty; AONESY states a 1-year manufacturer warranty. If warranty length is a deciding factor for you, Fulext has the edge. Otherwise, let your sleep position and your climate make the call.
