If you want a traditional on-ear headphone you can wear all day for calls, music and travel, choose Kinivo BTH240; if you need a soft headband you can sleep in, wash, and share with a second pair in the box, choose Perytong 2. These two get compared a lot because they both sit in the affordable wireless space, but they solve completely different problems. One is a foldable on-ear headset built around long battery life and hands-free calling. The other is a wearable fabric headband that doubles as a sleep mask and a sport band — and it comes as a two-pack.
• Kinivo BTH240's biggest strength: up to 30 hours of talk/play time, a foldable on-ear build, and a 2-year warranty with US-based support.
• Kinivo BTH240's biggest trade-off: it's a hard on-ear headphone with a headband and cups, so it's not something you'd wear lying on your side in bed.
• Perytong 2's biggest strength: a soft, washable spandex headband design with ultra-thin speakers, sold as a 2-pack, tuned for side sleepers and workouts.
• Perytong 2's biggest trade-off: 14 hours of playtime and a fabric speaker layout instead of proper ear cups — it won't match a real headphone for isolation or punch.
• Who Kinivo BTH240 is for: commuters, call-heavy workers, and anyone who wants one pair of conventional wireless headphones for the whole day.
• Who Perytong 2 is for: side sleepers, runners, travelers, and households that want two bands — one by the bed, one in the gym bag.
The Kinivo BTH240 PRO is the more conventional product of the two. It's an on-ear wireless headphone with a dynamic driver rated from 20 Hz to 20,000 Hz, Bluetooth 5, and a 10-meter (roughly 33-foot) wireless range. The cups use foam earpads with an adjustable headband, and the whole thing is foldable and sweat-resistant, which is why Kinivo positions it for an "active lifestyle" as much as for desk work. It also ships with a cable and a protective case, so you've got somewhere to put it when it's not on your head.
The headline number is battery: up to 30 hours of talk or play time, with a 2-hour charge time. That's the spec that shapes everything else. If you're the kind of person who charges something once or twice a week and then forgets about it, this is the design logic you want. There's a built-in mic for hands-free calling, meetings and voice chat, and the controls let you adjust volume, skip tracks and pause/play without reaching for your phone. Kinivo also backs it with a 2-year warranty and lifetime US-based customer support, which is a meaningful detail for a product you'll be folding into a bag and tossing around.
Who should buy it? In my opinion, the BTH240 fits anyone who wants a normal pair of headphones for commuting, working from a laptop, taking calls, or light exercise — and who doesn't want to think about charging constantly. It's also the better pick if you care about the headphones looking like headphones. The foldable, lightweight design and the included case make it an easy travel companion.
Who should skip it? If your main use case is falling asleep with audio on, this isn't the shape for it. On-ear cups press against your head, and the headband sits across the top of your skull — fine for sitting up, awkward for side sleeping. Also skip it if you want more than one pair in the house for the same money, or if you specifically want a fabric band you can throw in the wash.
The Perytong 2 is a different category of product entirely, even though it also streams audio over Bluetooth. It's a 3-in-1 wearable: sleep headphones, sport headband, and sleep mask. The band is made from skin-friendly elastic spandex in a gray/dusty-rose colorway, with ultra-thin stereo speakers sewn in and a dynamic driver rated 20 Hz to 20,000 Hz. Because the speakers sit flat against your ears instead of pressing into them through cups, side sleepers can lie on their side without a hard shell digging in. That's the whole point of the design.
Connectivity is Bluetooth 5.4 with a rated range of about 43 feet — noticeably longer than the Kinivo's 10 meters — and the newer Bluetooth version is aimed at faster pairing and a more stable connection. Battery is 14 hours with a 1-hour charge time, which Perytong frames around overnight use: fall asleep to something, wake up, and still have power for the morning. Noise control here is sound isolation, not active cancellation, so expect the fabric-and-speaker arrangement to soften the room rather than erase it. Controls are touch-based, and there's a built-in microphone.
The detail that changes the buying math is that it's a 2-pack. Two headbands, two sets of electronics. One can live by your bedside and the other in your gym bag or luggage, and when one gets sweaty you can wash the band and rotate the other in. For a couple, or for a household where someone keeps stealing the other's sleep band, that's genuinely useful rather than a gimmick.
Who should buy it? Side sleepers who want audio without ear pain, runners and gym-goers who want something that stays put and can be washed afterward, travelers dealing with long flights, and anyone who'd rather have two bands than one headphone. Who should skip it? If you want real bass response, strong passive isolation, or headphones that look like headphones for a commute or an office, the BTH240 is the more appropriate tool. The Perytong 2 is a comfort-first, sleep-first device.
• Best for battery life → Kinivo BTH240. Up to 30 hours versus 14 hours is more than double the runtime.
• Best for side sleeping → Perytong 2. The flat spandex band with ultra-thin speakers is built for lying down; the BTH240's on-ear cups are not.
• Best for hands-free calling all day → Kinivo BTH240. Built-in mic, on-board volume/track/pause controls, and a 2-year warranty with US-based support behind it.
• Best for workouts and hygiene → Perytong 2. Sweat-resistant and washable fabric you can refresh after every session.
• Best for two people or two locations → Perytong 2. It ships as a 2-pack, so you get a bedside band and a bag band in one purchase.
• Best for wireless range → Perytong 2. Roughly 43 feet versus the Kinivo's 10 meters (about 33 feet).
• Best for fast charging → Perytong 2. A 1-hour charge time versus 2 hours on the Kinivo.
• Best for travel with a case and cable → Kinivo BTH240. The foldable design and included protective case and cable make it the tidier thing to pack.
• Best for blocking out the room → Kinivo BTH240. It has active noise cancellation; the Perytong 2 relies on sound isolation only.
If I had to pick one for myself, I'd buy the Kinivo BTH240. Thirty hours of playtime, a foldable on-ear design, a built-in mic for calls, active noise cancellation, and a 2-year warranty with US-based support add up to the more versatile everyday product — the one I'd actually reach for on a commute, at a desk, or on a trip. That said, I'd recommend the Perytong 2 without hesitation to anyone whose priority is sleeping or training with audio: the washable headband, the 2-pack, and the 43-foot range are exactly right for that job. If your nights and your gym bag are the main event, get the Perytong 2. If your days are, get the Kinivo.
No. The BTH240 is an on-ear headphone with cups and a headband, which is uncomfortable when you lie on your side. The Perytong 2 uses a soft spandex band with ultra-thin speakers specifically so side sleepers can wear it in bed. For sleep, pick the Perytong 2.
The Kinivo BTH240 is rated up to 30 hours of talk/play time and charges in about 2 hours. The Perytong 2 is rated 14 hours and charges in about 1 hour. The Kinivo roughly doubles the runtime; the Perytong charges faster.
Both sit in the budget wireless space, but I don't quote prices here because they change often. Check the current price on Amazon using the button on this page, and remember the Perytong 2 is a 2-pack — so compare it as two bands, not one.
The Perytong 2. It's sweat-resistant, the fabric band can be washed after a session, and it stays flat against your head during movement. The Kinivo BTH240 is also sweat-resistant and fine for light exercise, but the on-ear cups and headband are less ideal once you're moving a lot.
