• YY KATTY's biggest strength: a genuinely ultra-thin 0.25-inch speaker profile paired with a 2-in-1 headband-and-headphones design, making it a natural fit for side sleepers and gym sessions alike.
• YY KATTY's biggest trade-off: Bluetooth 5.0 is a generation behind ASIILOVI's 5.4, and it charges in 2 hours for up to 10 hours of music playback.
• ASIILOVI's biggest strength: adjustable hook-and-loop sizing that fits all head sizes, plus Bluetooth 5.4 and 12 hours of playtime on a 2-hour charge.
• ASIILOVI's biggest trade-off: its fabric is polyester rather than the sweat-wicking sports-first fabric YY KATTY leans into, so it reads more "sleep accessory" than "workout gear."
• Who YY KATTY is for: side sleepers and gym-goers who want one headband that handles sweat, messy hair, and ear pressure in one go.
• Who ASIILOVI is for: anyone who wants an adjustable, gift-friendly sleep headband that also works for travel, office naps, and light workouts.
The YY KATTY headband earns its keep through one number: a 0.25-inch speaker thickness. That's the design decision everything else hangs on. Thin flat speakers sit flush against your ear instead of pressing into it, which is why YY KATTY positions this as a side-sleeping headband. If you've ever woken up with a sore ear from a bulky earbud, the flat-speaker approach here is the fix.
It's also built for movement. The 2-in-1 design means the fabric band holds your hair back and catches sweat while the speakers handle audio — no separate earbuds, no cords swinging around. There's a microphone built in, so you can take a call mid-run without pulling anything out of your ears. Add fabric construction with breathability in mind, and it covers yoga, jogging, the gym, and meditation without complaint.
Who should skip it? If you care about the newest Bluetooth generation, this is Bluetooth 5.0 — older than what ASIILOVI offers. And if you want a band that adapts to a very large or very small head, YY KATTY doesn't advertise adjustable sizing the way ASIILOVI does. It's listed in gray, sold as a single pack, and the device module needs to be removed before a full wash. In my opinion, this is the pick for someone whose priority is comfort against the ear during sleep and sweat control during workouts, in that order.
ASIILOVI's headband does three jobs at once: sleep headphones, headband, and sleep mask. That third role is the interesting one — it's meant to block light and noise while the speakers play, replacing the earbuds that fall out or dig into your ear overnight. The brand explicitly calls out side sleepers, air travel, office naps, and bedroom use, which tells you the design centers on lying down rather than running.
The standout spec is the adjustable hook-and-loop closure. That's a real difference from a fixed-size band: it's meant to fit all head sizes, which matters if you're buying this for a teenager or as a gift for someone whose head size you don't know. ASIILOVI leans into that gifting angle hard — it markets the headband as a present for teen boys and girls, men and women, family and friends.
On the tech side, it runs Bluetooth 5.4 with a 2-hour quick charge and more than 12 hours of playing time, plus a 45-foot range and auto-reconnect to the last paired device. The speakers are adjustable so you can slide them to sit over your ears. The fabric is polyester — soft, breathable, and hypoallergenic per the brand — and the headband is washable once you pull the speakers out. It ships in purple with a Type-C cable and a manual, and the lithium-ion battery is included rather than sold separately.
Who should skip it? If your main use is heavy sweating, the polyester build reads more sleep-focused than performance-focused. It's also unisex and one-size-via-adjustment, so if you specifically want a dedicated gray sports band with a fixed sporty fit, YY KATTY is closer to that brief.
• Best for side sleeping without ear pressure → YY KATTY Sports Headband Headphones. The 0.25-inch flat speakers and center-mounted module are designed specifically to avoid pressure on the ear.
• Best for battery life → ASIILOVI Sleeping Headphones Headband. It claims more than 12 hours of playback versus YY KATTY's up to 10 hours of music time.
• Best for newer Bluetooth → ASIILOVI Sleeping Headphones Headband. Bluetooth 5.4 against YY KATTY's 5.0.
• Best for a guaranteed fit → ASIILOVI Sleeping Headphones Headband. The adjustable hook-and-loop closure is meant to fit all head sizes; YY KATTY doesn't offer that.
• Best as a sleep mask replacement → ASIILOVI Sleeping Headphones Headband. It's explicitly a 3-in-1 headphones, headband, and sleep mask.
• Best for workouts and sweat → YY KATTY Sports Headband Headphones. The 2-in-1 sport design and breathable fabric are aimed squarely at gym, jogging, and yoga.
• Best as a gift for a teen or family member → ASIILOVI Sleeping Headphones Headband. It's marketed as an all-ages present with a Type-C cable included.
• Best for calls mid-activity → either. Both include a built-in microphone; YY KATTY lists up to 12 hours of call time, ASIILOVI lists HD call quality with its mic.
If I had to buy one, I'd take the ASIILOVI Sleeping Headphones Headband. Bluetooth 5.4, 12 hours of playtime, and the adjustable hook-and-loop fit make it the more flexible everyday headband — it works for sleep, travel, naps, and light workouts, and the adjustable sizing means it's a safer gift. The YY KATTY is the better call only if your single biggest concern is ear comfort for side sleeping or you want a band built primarily around sweating through a workout. Everything here is spec-based; check the current price on Amazon before you decide, since that's the one thing that can tip a close call.
Both claim to suit side sleepers, but YY KATTY is more specific about why: its 0.25-inch flat speakers and center-positioned module are designed to avoid ear pressure. ASIILOVI instead emphasizes adjustable speakers and its sleep-mask function.
ASIILOVI lists more than 12 hours of playing time on a 2-hour charge. YY KATTY lists up to 10 hours of music playback or 12 hours of call time on a 2-hour charge. For straight music listening, ASIILOVI edges ahead.
Yes — both are washable, but you have to remove the electronics first. YY KATTY says to take out the device module before a full wash; ASIILOVI says to remove the speakers and clean the headband.
ASIILOVI, in my opinion. Its adjustable hook-and-loop closure is designed to fit all head sizes, while YY KATTY is sold as one size without advertised adjustability.
