How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a single wearable that lulls you to sleep and doubles as a workout headband for nurses coming off a night shift, choose Perytong Sleep Headphones; if you need a hands-free bag that carries your phone, keys and cards while you walk the dog or hike, choose THLKLDKSZX Fanny Pack. They solve completely different problems. One goes on your head. The other goes around your waist.
• Perytong Sleep Headphones' biggest strength: a soft, washable mesh headband with ultra-thin on-ear discs and roughly 10 hours of Bluetooth 5.4 playback per charge — built for side sleepers, snorer-adjacent partners and light sleepers.
• Perytong Sleep Headphones' biggest trade-off: it isolates sound, it does not cancel it, and it is not a storage bag — it carries nothing but audio.
• THLKLDKSZX Fanny Pack's biggest strength: a lightweight polyester waist bag with zip pockets, a headphone jack and an adjustable strap that fits a wide range of body types.
• THLKLDKSZX Fanny Pack's biggest trade-off: it is not water resistant and it holds one main pocket — it is a carrier, not a listening device.
• Choose Perytong Sleep Headphones if you want better rest, white noise, or a sweat-friendly headband for the gym.
• Choose THLKLDKSZX Fanny Pack if you want your essentials secure and your hands free on a run, a hike or a dog walk.
Perytong's headband is a wearable speaker, not a pair of earbuds. The earpieces are flat, felt-covered discs that sit against your ears instead of inside them, which is the whole point: nothing protrudes, so side sleepers can roll onto one ear without a plastic shell digging in. If you have ever pulled earbuds out at 3 a.m. because they hurt, that design detail is the reason this product exists. The headband itself is a breathable mesh that stretches to fit most adult head sizes, and the whole thing is washable — you remove the speakers first, then toss the fabric in the wash. For anyone who wears a headband nightly, that is a real practical advantage over earbuds you can only wipe down.
Who should buy it: night-shift workers winding down in daylight, light sleepers in shared rooms, people who use white noise to mask a snoring partner, and gym-goers who want a sweat-friendly headband instead of earbuds that fall out. It is also a genuinely low-risk gift for someone who complains about ear pain from earbuds or earplugs, and it carries a two-year warranty.
Who should skip it: anyone expecting active noise cancellation. The listing is explicit that it isolates sound rather than cancels it — it muffles the room, it does not erase it. And if you need to carry a phone, wallet and keys, this does nothing for you.
THLKLDKSZX Fanny Pack: Who It's For
THLKLDKSZX's waist pack is a straightforward, no-nonsense carrier. It is made from lightweight polyester with a 3D-printed pattern, measures roughly 13.7" long by 5.5" wide and 5.5" high, and closes with a buckle plus a zipper over a single main pocket. The strap runs about 30 inches, and because it is adjustable, it is designed to sit securely across a range of body types rather than sliding around mid-stride. That is the core promise here: hands-free carrying that stays put whether you are running, hiking, cycling or walking the dog.
The feature that separates it from a generic fanny pack is the headphone jack. It is a pass-through for a wired headset, which means you can keep your phone zipped inside the bag and still listen while you move — a small thing, but it keeps your device out of your hand and out of the rain. Speaking of which: the bag is listed as not water resistant, so in a downpour your phone is only as protected as the polyester shell, which is not much. Keep that in mind if you walk in wet weather.
Care is easy — it is machine washable — and the unisex styling means it does not read as a men's or women's product. It is also pitched as a gift for birthdays and holidays, which fits its role as an inexpensive, universally useful accessory.
Who should skip it: anyone who needs a waterproof bag, needs multiple compartments for organizing, or is looking for something to listen through. It carries gear; it does not play audio.
Side-by-Side: Which Should You Choose?
• Best for sleep and white noise → Perytong Sleep Headphones. Ten hours per charge, auto shut-off, no low-battery beep.
• Best for side sleepers → Perytong Sleep Headphones. Thin on-ear discs that do not protrude, plus a washable mesh band.
• Best for carrying your phone, keys and cards → THLKLDKSZX Fanny Pack. A zippered main pocket and a buckle closure keep essentials secure.
• Best for wired-headphone users on the move → THLKLDKSZX Fanny Pack. The built-in headphone jack lets you zip your phone away and keep listening.
• Best for gym and workout sweat → Perytong Sleep Headphones. The band is designed for sports as well as sleep, so it handles basketball, tennis and running.
• Best for rainy-day use → Perytong Sleep Headphones (with a caveat). Neither is water resistant, but the fanny pack is explicitly labeled not water resistant, so your phone is at risk in the bag.
• Best for adjustable fit across body types → THLKLDKSZX Fanny Pack. A roughly 30-inch adjustable strap is designed to fit a wide range of wearers.
• Best for sleep-masking a snorer or shared room → Perytong Sleep Headphones. Sound isolation plus white noise playback is exactly its purpose.
My Verdict
No. The manufacturer states they isolate sound rather than cancel it. They muffle background noise and play white noise or music to mask it, but they will not silence a loud room on their own.
Yes. The band is designed for sports as well as sleep, with a stretchy mesh fit and a lightweight build, so it works for the gym, running and court sports.
No. It is listed as not water resistant, so it will not protect your phone or cards from rain or sweat. It is machine washable, which covers normal cleaning, not weather protection.
The THLKLDKSZX Fanny Pack. It has a zippered main pocket and a headphone jack so you can keep your phone zipped inside and still listen through a wired headset.
