What's inside the box
The Kalmely Sleep Mask, a USB-C charging cable, and a soft travel pouch. Available in black and pink.
How it works
Raised 3D cups block 100% of the light without ever touching your eyes. Ultra-thin wireless speakers pair to your phone over Bluetooth, so you can play music, rain or white noise to mask the cabin around you. Soft and side-sleeper friendly, with around 16 hours of battery.
Safety & warranty
Kalmely is a personal wellness device. 12-month manufacturer warranty. Charge only with the supplied USB-C cable, and remove the electronics before washing the fabric cover.
You land, but you're completely wrecked.
The light. The engine drone. The person next to you. You've never been able to switch off on a flight, so you arrive exhausted and lose the first day of every trip.
It's not you, normal eye masks slip, earplugs hurt, and pills leave you groggy. None of them block the light and the noise at the same time, comfortably, the whole way.
Kalmely was built for exactly this.

Two problems on a plane. One device.
Blackout + sound, in a single mask
01
Total blackout
Raised 3D cups block 100% of the light and never press on your eyes, so you can blink freely, even over lashes or lash extensions.
02
Drowns out the noise
Ultra-thin wireless speakers sit flat over your ears. Pair your phone and play music, rain or white noise to mask the engine drone and the cabin around you.
03
All-flight comfort
Soft, breathable fabric that stays put when you turn, side-sleeper friendly. Around 16 hours of battery, and fully washable.

An eye mask blocks the light but not the noise. Earplugs do the opposite, and hurt on your side. Pills knock you out but leave you groggy. Kalmely does all of it, comfortably, the whole flight.

"I fly for work most weeks. It's the first thing that actually gets me to sleep on the plane, and keeps me asleep through the trolley, the announcements, all of it."

Questions we hear most.
How long does the battery last?
Around 16 hours of playback on a full charge, easily a long-haul flight, or several shorter trips between charges. It recharges over USB-C in about 2–3 hours.
Does it work with any phone?
Yes. The speakers connect over standard Bluetooth, so they pair with any iPhone, Android phone or tablet. Play music, rain, white noise or a podcast, whatever helps you drift off.
Is it comfortable for side sleepers?
That's exactly who it's built for. The speakers are ultra-thin and flat and the fabric is soft, so there's nothing hard pressing into your ear when you turn onto your side.
Does it really block the light fully?
Yes, the raised 3D cups seal out 100% of the light without touching your eyes, including cabin lights and a neighbour's screen. You can open your eyes inside it and still see only black.
Can I wash it?
Yes. Remove the slim electronics and the mask is fully washable, so it stays fresh trip after trip.
Shipping & returns?
Free UK shipping, arriving in 5–7 business days. Not for you? You have a 100-day trial with free returns, we send a prepaid label and refund you in full.
