If you want a wireless, wearable headband that doubles as a sleep mask and workout companion, choose Perytong Sleep Headphones; if you need a simple wired over-ear set with a long cord so you can keep watching TV from across the room, choose 100SEASHELL Long Cord TV. These are two very different tools for two very different jobs, and the right pick comes down to whether you want to cut the cord or stretch it.
• Perytong Sleep Headphones — biggest strength: A 3-in-1 headband that works as a sleep mask, a Bluetooth sports headband and a wireless headset, with ultra-thin speakers built in so nothing presses on your ears. Bluetooth 5.4, 10+ hours of play time and a washable fabric band.
• Perytong Sleep Headphones — biggest trade-off: It's a fabric band with small embedded drivers, so it's built for comfort and discretion rather than audiophile-grade output, and you have to remember to charge it.
• 100SEASHELL Long Cord TV — biggest strength: Wired reliability with an extra-long cord and built-in volume control, so you can move around the living room and hear the TV clearly without disturbing anyone else.
• 100SEASHELL Long Cord TV — biggest trade-off: It's wired, has no microphone and no noise cancellation, so it's tethered to whatever you plug it into.
• Who each pick is for: Perytong for sleepers, side sleepers, joggers, travelers and anyone who wants hands-free audio without earbuds. 100SEASHELL for seniors and TV watchers who want one cable, one dial and zero setup fuss.
The Perytong Sleep Headphones solve a very specific problem: how do you listen to something in bed without jamming earbuds into your ears or clamping a rigid headband over your skull? The answer here is a stretchy spandex headband with two ultra-thin speakers sewn inside and the control module sitting in the middle of the band. That layout matters. Because the speakers are flat and the electronics sit at the center of your head rather than over your ears, there's no pressure point when you lie down. If you sleep on your side, this is the whole point of the design — you get audio without the sore ear that comes from a normal headphone pressing into the pillow.
On the tech side, you're getting Bluetooth 5.4 with a quoted range of 43 feet, a 20 Hz–20,000 Hz frequency range, and more than 10 hours of play time from a charge that takes about 2.5 hours. Controls are button-based, and Perytong backs it with a 2-year warranty.
Who should buy it: side sleepers, people who struggle to fall asleep with background audio, travelers on long flights, joggers and gym-goers who hate earbuds falling out, and anyone buying a gift for a sleeper or fitness person in their life. Who should skip it: anyone who wants maximum sound quality or noise isolation, anyone who doesn't want another device to charge, and anyone who needs a microphone for calls or a wired connection.
100SEASHELL Long Cord TV: Who It's For
The 100SEASHELL Long Cord TV is the opposite philosophy, and it's refreshingly straightforward. This is a wired, over-ear headphone aimed squarely at seniors watching television. The headline feature is right there in the name: an extra-long cord. If you've ever watched someone get up from the couch and yank their headphones off their head, you understand why that matters. The cord gives you room to move around the living room while the audio stays with you.
The second feature that matters just as much is the built-in volume control. Instead of hunting for the TV remote and fiddling with the TV's own settings — then realizing you've just blasted the whole house — you adjust the level right on the headphone. That means one person can watch at a comfortable volume while everyone else in the room hears nothing. For a household where someone has trouble following dialogue, this is the practical fix.
Who should buy it: seniors and older TV watchers, anyone who wants a wired setup with no charging or pairing, people in shared living spaces who need to watch without disturbing others, and anyone who wants a simple, single-cable solution. Who should skip it: anyone who wants wireless freedom, anyone who needs a microphone for calls, anyone who wants active noise cancellation (this model has none), and anyone whose TV lacks a 3.5 mm headphone output.

My Verdict
They're built for different jobs, so "better" depends on yours. Perytong is wireless, wearable and multi-purpose for sleep, workouts and travel. 100SEASHELL is wired, simple and made for TV listening. Neither replaces the other.
No. Perytong is a Bluetooth-only wireless headband with no headphone jack, so there's no wired option and no cable. The 100SEASHELL, by contrast, is wired-only via a 3.5 mm plug and also has no microphone.
The 100SEASHELL Long Cord TV. It's aimed at seniors, uses one standard 3.5 mm plug with no pairing, and has on-headphone volume control so they can set their own level without touching the TV settings. The long cord also lets them get up without unplugging themselves.
Match it to the job: pick Perytong if you want audio while sleeping, jogging or traveling without earbuds; pick 100SEASHELL if you want clear TV sound from across the room in a shared space. Check the current price on Amazon before deciding — that's the one variable that can tip a close call.
