• Voerou 3D — biggest strength: a 3-in-1 design that combines a Bluetooth sleep mask with built-in ultra-thin stereo speakers, so you can drift off to music, podcasts or white noise without wearing separate headphones.
• Voerou 3D — biggest trade-off: it is a sleep and nap accessory first. It blocks light and plays audio, but it is not a general-purpose headphone for commuting, calls or critical listening.
• MartiAudio Over Ear Headphones — biggest strength: a classic wired over-ear build with 40 mm dynamic drivers, a closed-back design, an in-line mic and a USB-C adapter for wide device compatibility.
• MartiAudio Over Ear Headphones — biggest trade-off: it is wired only. There is no Bluetooth, so you are tethered to your source device, and there is no built-in rechargeable battery.
• Who Voerou 3D is for: side sleepers, travelers, shift workers and anyone who wants audio plus total light blockage in bed.
• Who MartiAudio Over Ear Headphones is for: people who want an affordable wired headphone for office work, online calls, study sessions and daily commutes.
The Voerou 3D is best understood as a sleep tool that happens to play audio, not the other way around. The mask is built from memory foam and a soft, breathable, hypoallergenic fabric, and it uses a 3D contoured, sunglasses-shaped design that is meant to sit over your eyes without pressing on them. That contouring matters most for side sleepers, who normally feel every hard edge of a regular headphone against the pillow. The adjustable straps let you dial in a snug fit across head sizes, and the point of the whole design is full light blockage without pressure.
Inside the mask sit ultra-thin HD stereo speakers, paired with a Bluetooth 5.4 chip for fast pairing and low power draw. Everything is controlled on the mask itself: volume, track skipping and calls, so you never have to take it off to make an adjustment. Voerou rates the rechargeable battery at up to 10–12 hours of continuous playtime on a single charge, which is designed to cover a full night. A lithium-ion battery is included, and the mask ships as a single unit.
Who should buy it? If you struggle to fall asleep, share a room with someone who sleeps at different hours, or want white noise or a podcast piped in without earbuds digging into your ears, this is the product's clear purpose. It is also pitched at people dealing with insomnia, migraines or dry eyes, since the breathable fabric is designed to let air move while keeping dry air out.
Who should skip it? Anyone shopping for a main headphone. The Voerou 3D is not built for commuting, video calls, gaming or serious music listening. If you need a mic for meetings or want to hear your surroundings on a walk, this is the wrong tool. It is a bedtime device, and it is excellent at that narrow job.
The MartiAudio Over Ear Headphones take the opposite approach: a conventional wired headphone with a closed-back design and 40 mm dynamic drivers. The spec sheet lists a 20 Hz – 20 kHz frequency range, 40 ohm impedance and 94 dB sensitivity, which tells you these are easy enough to drive from a phone, laptop or Chromebook without extra amplification. The closed-back enclosure is the part that matters day to day — it improves noise isolation, so an open-plan office or a noisy bus becomes noticeably more workable.
Comfort is clearly a design priority. The ear pads use soft protein leather over memory foam, and the headband is adjustable so you can spread the clamping force to fit your head. That combination is aimed at long sessions — a full workday of calls, a study marathon, a long flight. The build is lightweight at 7.68 ounces and folds up, which makes it easy to throw in a bag between commutes and business trips.
Wired connectivity is the defining trade-off and, for some buyers, the defining feature. There is a 3.5 mm jack plus a USB-C adapter in the box, so it works with smartphones, tablets, laptops and anything else with either port. No pairing, no charging, no battery to die mid-call. The braided cable is designed to resist tangling and breakage, and the in-line controls handle volume, play/pause and calls, with a built-in microphone for meetings and phone conversations. MartiAudio also backs it with a two-year manufacturer warranty.
Who should buy it? Anyone who wants one dependable headphone for work, calls, study and daily travel, and who would rather not think about charging. It suits students, remote workers and commuters who want isolation without spending on active noise cancellation.
Who should skip it? If you want wireless freedom, this is not it — there is no Bluetooth. And if your priority is sleeping in your headphones, the over-ear cups and headband are the wrong shape for a pillow.
• Best for sleep and side sleeping → Voerou 3D. The 3D contoured mask and ultra-thin speakers are designed to be comfortable against a pillow.
• Best for light blockage → Voerou 3D. Full blackout is the core function; the MartiAudio is not designed to block light at all.
• Best for work calls and meetings → MartiAudio Over Ear Headphones. The in-line mic and controls are built for exactly this.
• Best for battery life → Voerou 3D. It is the only one of the two with a battery — up to 10–12 hours per charge. The MartiAudio has no battery to run down.
• Best for wireless convenience → Voerou 3D. Bluetooth 5.4 means no cable at all, which is a genuine advantage in bed.
• Best for device compatibility → MartiAudio Over Ear Headphones. The 3.5 mm jack plus included USB-C adapter covers phones, tablets, laptops and Chromebooks.
• Best for travel and commuting → MartiAudio Over Ear Headphones. Foldable, lightweight, closed-back isolation and no charging required.
• Best for sound quality and isolation → MartiAudio Over Ear Headphones. 40 mm dynamic drivers and a closed-back design are built for fuller, more detailed listening than a flat in-mask speaker.
In my opinion, these two products barely compete — they solve different problems, and the honest answer is that the right pick depends entirely on what you are buying it for. If your goal is falling asleep with audio and total darkness, I would buy the Voerou 3D; nothing in the MartiAudio's design addresses that need. If your goal is one reliable headphone for work, calls and commuting, I would buy the MartiAudio Over Ear Headphones, because the mic, the USB-C adapter and the closed-back 40 mm drivers make it the more useful everyday tool. Buy for the job you actually have, not the one you might have later.
FAQ
how to adjust headphones on iphone
how to adjust headphones volume
On the Voerou 3D, use the built-in mask controls or your phone's volume slider. On the MartiAudio Over Ear Headphones, use the in-line button controls on the braided cable or your source device's own volume. Both give you two ways to do it, which is handy if one is easier to reach.
how to adjust headphones sound
Sound character on the MartiAudio comes from its 40 mm dynamic drivers and closed-back design, so the biggest change you can make is getting a good seal with the adjustable headband and memory foam pads. On the Voerou 3D, positioning matters more than anything — adjust the straps so the ultra-thin speakers sit right over your ears, then fine-tune with your audio app's EQ.
how to adjust headphones on iphone for calls
The MartiAudio Over Ear Headphones handle calls through the in-line microphone and controls — press to answer, and the mic sits on the cable. The Voerou 3D also supports taking calls through its built-in mask controls, but for anything longer than a quick call I would reach for the MartiAudio, since its mic and closed-back cups are designed for conversation.
