How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want one pair of open-ear headphones that survives swimming, running and phone-free workouts, choose Voistek Bone Conduction Headphones; if you need a quiet, private way to fall asleep on a long flight without earbuds pressing into your ears, choose Deskium Bone Conduction Pillow. That's the short version. The long version matters, though, because these two products get compared constantly even though they barely do the same job — and the "for airplane" question is usually what pushes people toward one or the other in the first place.
Let me break down what each one actually is, who it fits, and where each one falls short.
• Voistek's biggest strength: a genuinely rugged open-ear design — IP68 waterproofing (submersible to about 2 meters for up to 2 hours), a flexible titanium frame, and a built-in 32GB MP3 player that holds roughly 8,000 songs so you can leave your phone behind.
• Voistek's biggest trade-off: bone conduction audio is not hi-fi. With 80 ohm impedance, 86 dB sensitivity and no active noise control at all, it's built for awareness and durability, not for blocking out a noisy cabin or delivering deep bass.
• Deskium's biggest strength: a slim silicone speaker that slides under your pillow and turns your bed into a private listening zone — four built-in soundscapes, up to 20 hours of playback, and a 30/60-minute auto-off timer.
• Deskium's biggest trade-off: it's a sleep and relaxation companion, not a headphone. It has no microphone, no water resistance rating, and no warranty listed. It also can't be worn on your head.
• Choose Voistek if you want one device for swimming, running, cycling and hands-free calls.
• Choose Deskium if you want discreet, earbud-free audio in bed, on a plane, or during a quiet break.
The Voistek pair is built around one idea: keep your ears open and your phone in your bag. The open-ear design sits outside your ear canal, so traffic, teammates and environmental cues stay audible while music plays. That's the whole point of bone conduction, and Voistek leans into it hard.
The spec sheet reads like a durability checklist. IP68 protection means it handles rain, sweat and full submersion, and the manufacturer notes it can sit in water up to 2 meters deep for up to 2 hours. The titanium frame is described as surviving 10,000 bends and 200 lbs of force, so head-size adjustments and rough handling shouldn't be a concern. Battery life is rated at 8 hours with a 1.5-hour charge, and Bluetooth 5.3 covers a 15-meter range across iOS, Android, tablets, laptops and desktops. There's a built-in microphone for calls and voice assistants, with Siri and Google Assistant both supported.
The 32GB MP3 mode is the standout feature. You copy music over via the magnetic charging cable, then double-click the multi-function button to switch between Bluetooth and MP3. That matters underwater, because Bluetooth doesn't transmit through water — so pool laps and snorkeling sessions run on stored tracks instead of a connection.
Who should buy it? Swimmers, runners, cyclists and gym-goers who want music without sealing off their ears, and anyone who'd rather not carry a phone on a workout. Who should skip it? If your priority is rich bass, total noise isolation, or a wired connection — there's no headphone jack — this isn't the tool. And if your main problem is falling asleep on a plane, keep reading.
Deskium takes the same bone conduction principle and points it at a completely different problem: getting to sleep without something jammed in your ears. You place the speaker's silicone surface under your pillow, and vibrations carry the audio up through the pillowcase. Nobody around you hears it. Nothing presses into your ear canal.
The hardware is modest and purpose-built. A 400mAh battery charges over Type-C in roughly 3 hours and delivers up to 20 hours of playback. Wireless 5.1 handles the connection with reduced latency. Four built-in soundscapes — ocean waves, train sounds, birdsong and rainfall — cycle with a button press, so you don't need your phone at all if you just want white noise. The M button's double-tap sets an automatic shutoff at 30 or 60 minutes, which means it powers down after you've drifted off instead of running all night. Deskium recommends setting your volume on the connected device before sleep, which is smart — it's easier to dial in a comfortable level before you're horizontal.
Size-wise it's 6.1 × 1.4 × 0.5 inches as a speaker, with overall packaging dimensions of 7.28 × 2.95 × 1.18 inches. It's white, made of ABS and silicone, and light enough to toss in a carry-on. Deskium lists no warranty, which is worth knowing up front.
Side-by-Side: Which Should You Choose?
• Best for swimming and water workouts → Voistek Bone Conduction Headphones. IP68 and MP3 mode make it the only one of the two that works in a pool.
• Best for falling asleep on a plane → Deskium Bone Conduction Pillow. Under-pillow audio, a 30/60-minute timer, and no earbuds to lose in a seat gap.
• Best for running, cycling and outdoor awareness → Voistek Bone Conduction Headphones. Open-ear design plus a titanium frame rated for 10,000 bends.
• Best for battery life → Deskium Bone Conduction Pillow. Up to 20 hours versus Voistek's 8.
• Best for hands-free calls → Voistek Bone Conduction Headphones. Deskium has no microphone.
• Best for phone-free listening → Voistek Bone Conduction Headphones. 32GB of onboard storage for roughly 8,000 songs.
• Best for shared spaces and quiet hours → Deskium Bone Conduction Pillow. Private audio that won't disturb a partner, roommate or seatmate.
• Best for travel that involves both → buy both. They solve genuinely different problems, and neither one replaces the other.
If you're specifically hunting for the best in ear headphones for airplane use, here's the honest read: neither of these is an in-ear headphone, and that's deliberate. Voistek keeps your ears open so you stay aware; Deskium skips your ears entirely. If what you actually want is sealed, isolating sound, look at in ear headphones for airplane noise instead. If you want lightweight open audio for a flight, Voistek's 15-meter Bluetooth range and 8-hour battery cover most routes. And if you're comparing wireless wireless earbuds for airplane sleep, the Deskium pillow is the cleaner answer — nothing to fall out of your ear at 35,000 feet.
In my opinion, the Voistek Bone Conduction Headphones are the stronger buy for most people, because they do more things well: swim-proof, phone-free music, calls, and a frame built to take abuse. That's a lot of utility in one device.
But if your actual problem is sleeping on a plane or winding down at night, the Deskium Bone Conduction Pillow is the one I'd reach for — it solves a problem headphones can't, quietly and without earbuds. For airplane trips specifically, I'd pick based on the job: Voistek for the flight itself, Deskium for the sleep at the end of it.
Yes — that's their core strength. IP68 protection allows submersion up to about 2 meters for up to 2 hours, and the 32GB MP3 mode plays stored music underwater, since Bluetooth won't transmit through water.
No. It has no microphone, no water resistance rating, and is designed to sit under a pillow rather than on your head. It's a sleep and relaxation speaker, not a wearable headphone.
Deskium, by a wide margin — up to 20 hours on a 400mAh battery charged in about 3 hours via Type-C, versus Voistek's 8 hours on a 1.5-hour charge.
Both products sit in different categories, so comparing them on cost alone isn't very useful. Check the current price on Amazon for each before deciding, since that's what will ultimately tip the scale.
