How to Use a SOUND Bluetooth Sleep Mask

Struggling with sleep? One of the biggest sleep disruptors is noise, and the world is getting louder every day.

The twist here is that certain sounds can help you relax and promote better sleep, such as colored noise (white, brown, and pink), nature sounds, and calming music. There are several ways to give them a listen, including through your mobile device, a white noise machine or, even better, a Bluetooth® sleep mask.

That said, we’re thrilled to introduce Manta SOUND Sleep Mask, our Bluetooth® sleep mask. It delivers 100% blackout and an immersive aural experience to help you unwind and achieve deep, restful sleep. This comprehensive guide covers everything from mask setup and its benefits to insider tips on using the mask to optimize your sleep experience.

How Does a Bluetooth Sleep Mask Work?

This type of sleep mask combines two elements: light-blocking and sleep-promoting sounds delivered directly to your ears via built-in Bluetooth® speakers.

The mask gives you the freedom to choose your personal sleep soundtrack by connecting to any Bluetooth®-compatible device. The wireless feature makes it convenient to take with you when traveling or to your workplace for a restorative (and well-deserved) snooze.

We also like to call it “the most comfortable Bluetooth® sleep mask in existence.” If that sounds like a bit of a stretch, we’re confident that owning one will convince you otherwise.

Let’s explore its features:

  • The head strap houses ultra-thin, adjustable Bluetooth® speakers that are encased in soft foam.

  • The mask has an amazingly long 24-hour battery life, even when played at maximum volume.

  • The speakers and control unit are completely removable for easy cleaning. Both the head strap and eye cups are 100% machine washable.

  • C-shaped eye cups keep pressure off your lashes and eyes. The cups also taper near your temples; each has a smart bubble that expands as you switch sides for ultimate side-sleeping comfort. The adjustable eye cups feature a micro hook-and-loop backing that adheres to the interior of the head strap.

  • The head strap is adjustable for a custom fit. The anti-slip strap secures around your head with a micro hook-and-loop closure. It also comes with an optional over-head strap to ensure it stays put.

  • The head strap’s 3D-knit mesh design and cooling perforated foam make it incredibly breathable – perfect for hot nights.

How Do You Use Manta SOUND Sleep Mask?

Now, let’s get down to the nitty-gritty. Using SOUND Mask is pretty simple. Still, we figured a detailed guide would be helpful.

Step 1: Familiarize Yourself With Its Parts

  • Plug the cable into your laptop, or, if you prefer, attach it to a power adapter and plug it securely into a power outlet.

  • The power indicator on the mask’s front should light up red, signaling that it’s charging.

  • Wait for the indicator light to turn green, indicating it’s fully charged. Charging should take about 100 minutes from when the battery is completely drained.

Note that the mask doesn’t power on while charging.

Step 3: Adjust the Fit of the Sleep Mask

Achieve a perfect fit by adjusting the eye cups, head strap and optional over-head strap.

  • Hold the power button at the mask’s front for at least 3 seconds until you hear repeating tones.

  • Activate Bluetooth® on your device, then select "- Manta SOUND 2" from the list. Pairing may take up to 15 seconds.

Tip: To pair the mask with a new device, hold the power button for 10 seconds to disconnect your current one and enter pairing mode. Repeat the pairing process for your new device.

Step 5: Operate the Bluetooth® Sleep Mask

How Do You Clean and Maintain Manta SOUND Sleep Mask?

Any sleep mask benefits from regular washing. Think about it: a sleep mask sits next to one of (if not the most) sensitive parts of the body: your eyes (not to mention the skin on your face).

Now, the thing with most other Bluetooth® sleep masks is that you can’t expect to clean them as thoroughly as you should. Wetting the electronics ruins the mask. You're left with spot cleaning techniques that fall short.

The head straps and eye cups of Manta SOUND Mask are machine-washable. However, the control unit and the speakers aren’t. We designed the mask so the control unit and speakers are completely removable, making it easy to wash. We recommend washing the mask before its first use.

Follow these simple instructions to get the mask spic and span:

A hand pulling out the speakers from the strap of a Bluetooth® Sleep Mask.

  • Open the magnetic closure at the top of the mask and gently pull out the control unit.

  • Tuck the headphone adjustment tabs into the mask.

  • Slide the speakers toward the center of the mask, then pull them out.

  • Gently wipe down the control unit and speakers with a soft, dry cloth to remove any lint or dust.

  • Set them aside.

  • Put the head strap, optional over-head strap, and the eye cups into a laundry bag.

  • Place them into a washing machine.

  • Ensure that you’re using a mild detergent and don’t add any bleach.

  • Machine wash the head strap cold at up to 30 degrees Celsius (86 degrees Fahrenheit).

  • Lay the head strap and eye cups to air dry on a flat, clean surface or on a dry towel. Do not tumble dry or iron.

Apart from washing the mask, here are some tips on how to maintain it properly:

  • Store the mask when it’s not in use. You can place the mask in a storage bag and keep it in a drawer that’s free of dust and dirt.

  • Use the USB-C cable that comes with the mask to ensure optimal connectivity and charging. However, the mask is compatible with any USB-C cable.

  • Charge the mask after each use to prolong its lithium-ion battery’s lifespan. Charging the mask before it's fully discharged is also recommended.

What Are the Benefits of Using a Bluetooth Sleep Mask?

So, what makes a Bluetooth® sleep mask so coveted today? It’s got excellent benefits that make it hard to resist.

Let’s tackle the most obvious benefit. A Bluetooth® sleep mask blocks out light while you sleep. It's a scientific fact that total darkness is necessary for high-quality sleep. Exposing your retinas to light signals your brain that it’s time to be awake and alert. Meanwhile, darkness tells you it’s time to go to bed. It also triggers the release of the sleep-promoting hormone melatonin.

It’s also a way better option than screen time for winding down from a hectic day. Blue light from gadget screens makes it hard to drift off.  

Next, a Bluetooth® sleep mask allows you to choose which sounds lull you to sleep, as it pairs with any compatible device. You’ve got the world of sound at your fingertips, whether you prefer white noise, lullabies or ASMR for sleep.

A Bluetooth® sleep mask is also super helpful when you share a bed. You can listen to your favorite sleep tunes without disturbing your partner, or use them to mask their snoring.

What Are Tips for Enjoying Manta SOUND Sleep Mask?

First things first, let’s talk safety. You might be wondering: Is it bad to wear headphones to sleep? The truth is, exposure to high volume levels for prolonged periods of time is dangerous for your hearing. A rule of thumb is to avoid listening to sounds at over 70 decibels.

Here are a few safety tips to keep in mind when using the mask:

  • Set the mask’s volume to a low level before putting it on.

  • Ideally, use your mask at the lowest possible level.

  • If you must listen to your mask at a high volume, avoid doing so for an extended period.

  • If you’re listening to sounds (like white noise) that can drown out disruptive external noise, ensure that the volume isn’t loud enough to mask emergency alerts or the sound of someone speaking.

  • Do not use the mask while driving any type of vehicle or operating machinery.

  • Children aged 3 and under shouldn’t use the sleep mask. Small parts and the cord may pose choking and strangulation hazards. In general, it shouldn’t be used by anyone unable to adjust, operate and remove the sleep mask on their own.  

  • When it’s time to say goodbye, bring the mask to an approved electronic equipment recycling facility for disposal. The mask isn’t classified as household waste.

Now that you know how to use it safely, here are a couple of tips for enjoying your mask to the fullest:

  • Make listening to sleep-promoting tunes on your mask part of your pre-bedtime routine. It’ll help you unwind and set the stage for a good night’s sleep.

  • Download your audio files, then put your paired device into airplane mode to prevent interruptions.

  • Consider setting a sleep timer on your paired device to give you enough time to transition into sleep while avoiding prolonged exposure to sound.

  • Travel with Manta SOUND Mask. Not only will it help you relax as a passenger, but it’ll also serve as something familiar from home to help you adjust to a new sleeping environment.

  • Experiment with different audio. There’s a world of sleep-promoting sounds out there waiting to be heard.

  • Use the mask to listen to your favorite sleep app, such as Calm.

  • Consider Manta SOUND Mask as your new meditation buddy. Listen to guided meditations or music on it, while it keeps light at bay for deeper focus.

Frequently asked questions

The mask features a rechargeable lithium-ion battery, rated for ~24 hours of use per charge.

You need a USB-C cable to charge Manta SOUND Sleep Mask. Any USB-C cable will work, including Apple and fast-charging cables. However, we recommend using the mask’s accompanying USB-C cable for optimal compatibility and charging.

Yes, you can charge the mask with a power bank, provided that it has an output of at least 5V to support the 3.7V and 250mAh battery specifications of the Manta SOUND Sleep Mask.

There are a few reasons the sleep mask might not be charging. You’ll notice this if the power indicator on the front doesn’t light up.

A common issue is that the USB-C charging cable isn’t fully connected to the mask or power source. Ensure that the cable is fitted into the mask’s charging port. If you’re using an adapter, make sure it’s plugged securely into the outlet.

Broken cables or adapters can also cause charging issues. They might not provide adequate power or connectivity. Try using a different cable and/or adapter to see if it solves the problem.

If neither of the above is the cause, try resetting the mask. Try holding the power button down for 15 seconds to force a reset. If this doesn’t work, drain the battery completely. Then recharge and reboot the mask.

Yes, the mask turns off automatically after 30 minutes without audio.

Connect the sleep mask to other Bluetooth®-compatible devices, such as your smartphone, laptop, or tablet, by pressing the mask's power button for 3 seconds to enter pairing mode. Ensure the Bluetooth® feature on your smart device is enabled to search for compatible devices. Once “- Manta SOUND 2” appears on your device’s screen, click on it to pair your device with the mask.

To prevent the mask from disconnecting frequently, keep it within 1 meter of your device. The closer, the better.

Yes, you can connect it to an Alexa-enabled device, such as the Echo Dot, but you cannot use the Alexa app to control the sleep mask directly.

First, open your Alexa app. Then, put the mask into pairing mode by holding the power button down for 3 seconds. On the home screen of the Alexa app, click on “Devices,” then click on “Echo.” Click on your preferred Alexa-enabled device. In device settings, click on “Bluetooth Devices.” Then, click on “Pair a New Device.” Alexa will search for available devices. Click on “- Manta SOUND 2” once it appears on the screen.

Once successfully paired, you can command Alexa to play specific sounds and music (through Spotify), set a timer, control playback, and listen to it on the mask.

No, you cannot answer or make phone calls while using Manta SOUND Mask. It doesn’t have a microphone.

No, the mask does not play built-in sounds or music. It uses Bluetooth® technology to connect to compatible devices and play audio through its built-in speakers.

No, Manta SOUND Sleep Mask doesn’t have active noise cancellation. Its Bluetooth® headphones were designed to cover the ears to minimize external noise, but not so much that you won’t hear emergency alerts, such as fire and burglar alarms.

Manta SOUND Mask offers superior sound quality compared to most other Bluetooth® sleep masks on the market.

The mask has 30 levels of volume adjustment.

You can achieve the best fit by adjusting the mask’s eye cups and head strap.

To adjust the mask, lay the head strap flat with the eye cups facing upwards. Remove the eye cups and reattach them so they sit closer towards the center of the head strap.

Then put on the mask, adjusting the head strap’s micro hook-and-loop closure to fit snugly around your head. The strap should sit at the base of your skull, neither too tight nor too loose. The eye cups should surround your eyes. Adjust the placement of the eye cups if you feel any pressure on your eyes or see light.

The sleep mask also comes with an over-head strap for a more secure fit. Simply attach either end of the strap to the appropriate loop located on either side of the head strap (there are three loops, allowing for a custom fit). You can further adjust the top strap by lengthening or shortening it via the micro hook-and-loop backing.

To remove the control unit and Bluetooth® speakers, open the magnetic closure at the top of the head strap, then gently pull them out. Note that the battery unit is connected to both speakers. So, you will need to slide each speaker towards the center opening to remove the electronics altogether.

To reattach the control unit and speakers, open the magnetic closure, slide the speakers back into place, and pull the headphone adjustment tabs to sit outside the mask. Place the control unit in the center of the head strap, then snap the magnetic closure shut.

To wash the head strap of Manta SOUND Mask, remove the control unit and speakers completely. Put the strap into a laundry bag. Place the bag in a washing machine and wash it on a cold setting.

You can also opt to hand-wash the head strap. Fill a clean basin with cold water and add a teaspoon of mild liquid detergent. Submerge the head strap and let it soak for up to 5 minutes, gently moving it around. Remove the soapy water from the basin and refill it with cold water. Place the strap inside, moving it gently. Repeat until all the soap suds have disappeared.

For both methods, lay the head strap flat on a clean towel to air dry.

You can restore the stickiness of the micro hook-and-loop closure of the head strap and the backing of the eye cups with gentle cleaning.

Use a toothbrush, fine-tooth comb, or tweezers to remove lint and dirt from both the hook and loop sides. For the loop side, gently comb the fibers apart. If this side is matted, soak it in warm water and scrub it with a soft brush. Let it air dry thoroughly before use.

Another option is to use sticky tape to remove the lint and dust from both sides.
