If you want a wireless audio headband that doubles as a sleep mask and a workout band — and you'd rather split one purchase between two people — choose Perytong 2; if you need noise-reducing ear protection sized for a baby or toddler, with a headband that converts between earmuff and flat-band modes, choose Momfree 2-in-1.
• Perytong 2's biggest strength: two complete Bluetooth 5.4 audio headbands in one box, each with ultra-thin 40mm dynamic drivers, up to 14 hours of playtime per charge, touch controls, a built-in mic, and removable speakers so the fabric can be machine washed.
• Perytong 2's biggest trade-off: it's an audio product first. It offers passive sound isolation, not certified hearing protection, and it's sized and marketed for adults — not infants.
• Momfree 2-in-1's biggest strength: a genuine safety accessory. It's engineered to cut roughly 25dB of noise for children aged 3–48 months, with memory foam and PU leather cushions, a non-slip adjustable headband, and a convertible design that detaches into a soft flat band for naps.
• Momfree 2-in-1's biggest trade-off: there is no audio at all — no Bluetooth, no speakers, no battery — so it can't play music, white noise or a podcast.
• Who each pick is for: Perytong 2 for adults who want private listening at night or during workouts; Momfree 2-in-1 for parents protecting a small child's ears at fireworks, on flights, or at loud events.
Perytong 2 is a wearable audio device disguised as a headband. The two-pack angle is the part I find genuinely clever: you get two independent headbands, each able to pair with its own phone or tablet over Bluetooth 5.4, so two people in the same bed can listen to completely different things without splitting a pair of earbuds. A couple where one person wants a sleep podcast and the other wants an audiobook is exactly the scenario this design solves. The stated Bluetooth range runs to about 43 feet, which is generous enough to leave a phone charging across the room.
The comfort story is where the specs matter most. The speakers are 40mm dynamic drivers built thin enough to sit flat against the ear, which is the whole reason side sleepers can lie on their side without a hard plastic shell digging in. The fabric is a spandex, nylon and elastic blend — breathable and sweat-absorbent — and the speaker pods come out so the band itself can go in the washing machine. That combination covers three jobs in one item: a sleep mask that blocks light, a headband for jogging, yoga or gym sessions, and a hands-free calling device thanks to the built-in microphone and touch controls. Battery life is rated at up to 14 hours on roughly a one-hour charge, which is enough for a full night of sleep sounds plus a morning workout.
Buy Perytong 2 if you're an adult who wants to fall asleep to audio without earbuds pressing into your ears, you want a washable band for sweaty workouts, or you're buying for two people at once — roommates, partners, or a parent and an older child who each want their own audio. Skip it if you're shopping for an infant or toddler, or if you specifically need certified hearing protection rather than sound isolation. This is a listening device, not a safety device.
Momfree 2-in-1: Who It's For
The 2-in-1 element is the convertible design. The earmuffs detach, and what's left is a soft, flat headband — useful for stroller naps or sleeping on a flight when full ear cups would be bulky against a car seat or a parent's shoulder. The fit is built around children: a stretchy, non-slip adjustable headband sized for that 3–48 month window, with PU leather and memory foam cushions that are breathable and skin-friendly, and a lightweight, pressure-free structure so a toddler isn't fighting to pull it off. Construction is ABS and PVC, which is a sensible choice for something a small child will grab, drop and chew-adjacent. It ships as a single unit with a mini carrying bag for storage.
Buy Momfree 2-in-1 if you're a parent or gift-giver shopping for a baby or toddler, you have a flight, fireworks display, wedding or noisy event coming up, or you want something that doubles as a soft sleep band for stroller naps. Skip it if you want to listen to music or audio yourself — there's no Bluetooth, no speakers and no battery here. It's a passive protector, and it's sized for small heads only.

My Verdict
how to fix headband on headphones
It depends what's actually broken, and the two products here are built differently. On Perytong 2, the headband is a fabric band with removable speaker pods, so the practical fix is to reseat the pods in their pockets and wash and reshape the fabric if it's stretched or soiled. On Momfree 2-in-1, the headband is a stretchy adjustable strap with a non-slip fit and the earmuffs detach from it, so check that the cups are clipped back on properly and that the adjuster is set snug before assuming anything is faulty. If the band itself is torn or the electronics have failed, both carry manufacturer support — Perytong lists a 2-year manufacturer warranty.
They're for different sleepers. Perytong 2 is designed for adults — the flat 40mm speakers let side sleepers rest on their ear, and the band doubles as a light-blocking sleep mask with up to 14 hours of audio. Momfree 2-in-1 is for babies and toddlers aged 3–48 months, and its sleep use is about quieting loud surroundings and converting to a soft flat band for naps, not playing sound.
Just ear protection, in my opinion. Momfree 2-in-1 has no Bluetooth, no speakers and no battery by design — its job is roughly 25dB of noise reduction for sensitive infant ears at fireworks, concerts, flights and sports. Putting audio drivers on a baby isn't the goal; blocking loud noise is. Bluetooth audio belongs on the adult side of this comparison, with Perytong 2.
Realistically, no. Momfree 2-in-1 is sized Small and specified for ages 3–48 months, with a stretchy non-slip headband built for a toddler's head and a snug, pressure-free fit for small ears. An adult head won't get the intended seal, and without that seal the noise reduction won't perform as designed. Adults wanting audio at night or during workouts should look at Perytong 2 instead.
