SleepPhones Review: Is It the Best Friend of A Side Sleeper?

By Oktay Ozadam

AcousticSheep SleepPhones

When I stumbled upon my first pair of headphones designed for sleeping, there wasn't much to be impressed by. Their build quality was still uncomfortable, the Bluetooth technology was still in need of advancement, and they weren't effective for sleeping.

But now, it's 2019, enter AcousticSheep with their new line of SleepPhones.

AcousticSheep affectionately calls their product's design a one of a kind: "Headband Headphones."

After seeing the design for myself, I wanted to create this comprehensive review to see if they can live up to the hype and benefit side-sleepers everywhere.

A Complete Review of SleepPhones

A Design Rooted in Comfort, Perhaps Lacking in Consistency

The design of these headphones appears to be perfect at getting the job done for sleeping. Their fleece fabric is comfortable for falling asleep and keeping you asleep. While the actual band part of the headphones is useful, there are still some other areas of the device that vary in consistency.

Some users have complaints about the SleepPhones, saying that the wire that comes with the SleepPhones classic is very low on the spectrum for quality's sake. Users claim that this device is either built tough and will last for a year and beyond, while others had devices that gave out in 3 months.

The cordless, SleepPhones Wireless edition appears to be the solution to dodging the bad-wiring issue, but this comes with a price increase (from $30 - $99).

The Battery

While we're on the topic of inconsistency, the battery on the wireless model seems to follow some of the same issues. However, it simply isn't consistent.

Users have said that the battery has lasted them anywhere from 6-9 hours, but AcousticSheep markets that the device should consistently last up to 10 hours with 3-hour charging time. If this were the case, the SleepPhones wireless would last a full night's sleep and be finished charging 3 hours after you left for work.

Perhaps the negative reviews were done in correlation to faulty devices, but regardless, if you purchase a pair, you should thoroughly test your device for any of these inconsistencies.

Overall, as far as comfort is concerned, these are great headphones for sleeping with a uniquely comfortable headband.

Individual Product Usability

AcousticSheep's SleepPhones line up comes in six different models you can choose from. To make things more transparent, I will highlight some critical points for each model.

Things That are True for Each Product

Each pair of SleepPhones will come with two fabric options that you can choose from.

  • SheepCloud Fabric: Fleece:Made from 95% polyester and 5% spandex, this option is the warmer, heavier one. If you find yourself getting cold at night and want something that feels "snug" or "fitting", then this is your best bet.
  • SheepCloud Fabric: Breeze:This option is made from the same percentage combo of polyester and spandex; however, it is more lightweight and cooling. Users that have complained about the fleece being "too heavy" found that switching to this option solved their issues.

Each pair of SleepPhones also comes with different sizes to match the demand for different head sizes. It is recommended that you look at AcousticSheep's guide for finding which size will work best for you.

SleepPhones Classic:

The SleepPhones Classic is the cheaper, corded option from the lineup. These are not consistent when it comes to build quality of the wires and that you may expect to replace this device sooner than expected.

To remedy this issue, you will want to avoid this option if you are someone that rolls around a lot during sleep. Increased tension and stress on just about any wire will decrease its life span.

Battery Life (As advertised): Uses a cord, not applicable.

SleepPhones Wireless:

This option is a lot more efficient than the SleepPhones Classic when it comes to a comfortable sleep. The lack of the wire gives peace of mind to the side-sleeper that rolls around a lot during their sleep. Although it is about $60 more expensive, this model is a lot more consistent than the classic option.

Simply pair the SleepPhones to your Bluetooth device and enjoy 15-30 feet of movement while still listening to sounds that help you fall asleep.

  • This option also includes a sub-option, the SleepPhones Wireless with Microphone. The added microphone module will allow you to push a button on a remote-like add-on that will answer calls and will enable you to talk via your SleepPhones.

This eliminates the need to pick up your phone and saves you from any excess distractions.

Battery Life (As advertised): Up to 10 hours.

SleepPhones ASMR Edition:

The ASMR edition is NOT a Bluetooth option but instead comes pre-loaded with 8 hours of ASMR content created by popular ASMR artists on YouTube. Given that the sounds are pre-loaded, this device does not need any excess wires and will have a significantly longer battery life (up to 20 hours).

If you are someone that likes customizability when it comes to sleep-sounds, then this might not be your best bet. However, if you find that you keep up with ASMR videos on YouTube to help you relax, then this might just be your new companion.

Battery Life (As advertised): Up to 20 hours.

SleepPhones Effortless:

SleePhones Effortless feature effortless charging which essentially, is just a charging pad that you can set the SleepPhones on top to wirelessly charge them "effortlessly."

Honestly, I would consider this option to very gimmicky. They're basically a pair of SleepPhones Wireless with a wireless charging pad. Given the simplicity, I cannot warrant the need to spend 50 extra dollars for it.

However, if you're someone that likes an entirely cordless nightstand and a modern design, then this might be a more discreet option.

Battery Life (As advertised): Up to 10 hours.

SleepPhones Simple:

The SleepPhones Simple is very similar to the SleepPhones ASMR Edition. The main difference is what comes pre-loaded onto the device. The SleepPhones Simple is pre-loaded with 17 high quality, white noise like sounds that will help you fall asleep.

To keep you from walking in blind, or this case deaf, AcousticSheep has given you the option to preview samples of each audio-track to get an idea of what to expect.

That same warning I gave you on the ASMR Edition applies here. If you are someone that likes customizability with sleep-sounds, then this might not be your option.

Again, the SleepPhones Classic and SleepPhones ASMR Edition are NOT Bluetooth devices and come with pre-loaded sounds.

Battery Life (As advertised): Up to 20 hours.

SleepPhones TellyPhones:

With this option, you receive a pair of SleepPhones that comes with a Bluetooth transmitter that you can connect to your TV. This will connect wirelessly to your SleepPhones and enable you to listen to the TV without bothering your partner.

Keep in mind; this option can still connect to other Bluetooth devices such as your cellular device.

Battery Life (As advertised): Up to 10 hours.

BONUS: SleepPhones Headband [No Speakers]:

If you find yourself in love with any of the models I just mentioned because of their comfort, then you can consider buying just their headband. Because they don't have speakers, there isn't any ambient sound reduction, but you can at least feel comfortable no matter where you are.

Other Purchasing Options:

If something on your current pair of SleepPhones was to break, you can save money and purchase individual components separately such as:

  • SleepPhones Speakers (though prices vary depending on model)
  • SleepPhones Effortless Charing Kit
  • Extra SleepPhones Bluetooth Module with or without microphone
  • A cute plush SleepPhones Sheep doll (a good little sleep companion, it was too cute, I had to mention it.)

AcousticSheep also has a line of headband headphones for running called RunPhones. These come with almost identical options to the SleepPhones such as Classic, Wireless, Effortless, etc. If you want a comfortable pair of headphones for running, you might want to check them out here.

Keep in mind, that a lot of users have complained about the inconsistency when it comes to their device's battery life. As I said before, make sure you test your device for any of these inconsistencies and make sure that the device is performing as advertised!

So, Are These Headphones Perfect for Side-Sleepers?

Even if there are complaints about the device's functionality, it would appear that the comfort is unmatched. Many people turn to AcousticSheep's SleepPhones because they offer a unique experience.

Side sleepers often complain about headphones for sleeping when their design is rugged or uncomfortable. AcousticSheep bypasses this by placing the headphones inside of a comfortable headband which makes these a competitive option for bed-friendly headphones.

If you find yourself frequently sleeping on your side, then you need to give these headphones a whirl. They might just solve any of your past comfort issues with other brands.

AcousticSheep's SleepPhones utilize a headband to stow away padded speakers that deliver the user sound. These speakers fit into the headband and have some free-range of movement as they move around independently of the headband.

The sound quality works to deliver ambient sound reduction to the user, but they are not Bose quality headphones. I think this fact is important to mention because you should not expect Bose level quality in a $99 headband.

Users have said that the quality is sufficient enough while sleeping or for casually listening to music while at work with no issues.

What is Ambient Noise Reduction?

SleepPhones deliver ambient noise reduction to the user.

Ambient noise reduction is the process of reducing the intensity of incoming sounds by the use of white-noises.

It is important to realize that this does not entirely cancel out incoming sound but works to reduce the loudness of that incoming sound.

AcousticSheep states that they want to reduce the volume of incoming sounds, but they don't want to block it out completely. Here's their statement on the matter:

"We market the product as noise-reducing rather than noise canceling. Our products are not canceling because we feel that being able to hear a fire alarm or a child monitor in the middle of the night is important."

Q: Can it block snoring?

A: Yes, but you need to have the volume up loud enough to block out the individual intensity of the snore. Unfortunately, not every husband snores the same. Therefore you need to find the appropriate sound level that works for you.

In fact, many users have told AcousticSheep that their SleepPhones helped to save their marriage.

Q: Can it block sound with no noise being played?

A: Scientifically, to some extent. Anytime you rest something on your ears; you will muffle the incoming sound. However, sound with enough intensity or vibration will still make it into the ears and get translated by the brain. If you are trying to block out snoring, you will need some type of audio to be playing that will contribute to the ambient noise reduction process.

Q: What is the frequency range of these speakers?

A: AcousticSheep markets their speakers as having the capability to reach 20 Hz to 20 kHz, making it perfect for binaural beats or ASMR type sounds.

Q: What is ASMR? What are binaural beats?

A: ASMR stands for "Autonomous sensory meridian response" and is described as a satisfying, almost tingling feeling. ASMR is often triggered by gentle sounds like teeth clacking together or fingernails impacting on a keyboard.

Though it sounds weird to some, it is actually a very popular phenomenon online, with some channels producing strictly ASMR content and boasting over a million subscribers.

On the other hand, binaural beats are specific sounds that derive a relaxation response within the brain. These beats are therapeutic to some and usually reside in specific frequencies such as 8 to 13 Hz or 14 to 30 Hz.

Q: Can other people hear what I'm listening to?

A: Users have stated that others cannot hear what you are listening to unless they were to have their head up against yours. Others have likened it to wearing regular earbuds, perhaps when you have the volume up all the way someone with acute hearing could have the chance to hear what you're listening to.

However, for most users, at a reasonable volume, you will be safe to know that nobody around you can hear what you're playing.

Q: Well, then, how loud might they be for someone sitting/sleeping next to me?

A: If you're blasting it at full volume and laying on the ear, then they might hear it. However, that type of decibel exposure is not only bad for your ears but counter-intuitive for falling asleep.

At an average listening volume, your partner will not hear anything you're listening to.

Q: Will I hear my alarm in the morning, or worse, if a smoke detector were to go off?

A: Yes, these devices only work to reduce incoming noise, not block them. Most alarm sounds or smoke alarms go off at a frequency that counters any active noise reduction technology.

Although, because most alarm sounds are not the same nor consistent, I suggest that you test your alarm's volume before you go to sleep with the SleepPhones on and at your desired volume. The only downside to this test is that you might have to wait for your husband to start snoring to get appropriate levels (haha!).

Overall, the SleepPhones are designed to offer an audio experience that is effective for active noise reduction or casual listening. You can happily expect them to get the job done when it comes to these tasks.

What Comes in The Box?

Now, obviously, we have touched base on a lot of different models. To keep it simple, I'll only go over what comes in the box with the Classic and Wireless models.

The Classic Option:

Comes with (direct from AcousticSheep):

  • Flexible 4-foot (48 inches) stereo audio cord
  • Removable speakers in a hypoallergenic, machine-washable fabric headband
  • Headband made from our proprietary SheepCloud™ fabric
  • Free sleep sound online downloads and free iPhone® app
  • One-year limited warranty and 30-day return policy
  • User manual

The Wireless Option:

  • Comes with (direct from AcousticSheep):
  • USB charger included with purchase
  • Built-in volume and play/pause controls
  • Headband made from our proprietary SheepCloud™ fabric
  • Removable speakers in a hypoallergenic, machine-washable fabric headband
  • Free sleep sound online downloads and free iPhone® app
  • One-year limited warranty and 30-day return policy

Warranty & Return Policy Information:

AcousticSheep headphones are available through the manufacturer, AcousticSheep, or Amazon. When it comes to warranty, it is better to order your SleepPhones through AcousticSheep as they offer a 1-year limited warranty on all of their products. Amazon, on the other hand, only comes with a 30-day warranty.

By their policy AcousticSheep abides by a 30-day return policy and will likely follow this through Amazon as well. Just to maintain peace of mind when purchasing, I recommend that you order through AcousticSheep directly.

Optional Alternatives to SleepPhones

When it comes to finding the perfect sleeping earphones, sometimes intensive reviews for a product just don't end up leaving you wanting to purchase. If AcousticSheep's SleepPhones headphones aren't doing it for you, then here are two comparable alternatives:

  1. CozyPhones: CozyPhones feature a similar headband design made for sleeping. These headphones come with a cool, comfortable, and ergonomic design. They make both an adult and kids' version for you to select from.

When it comes to price, the CozyPhones takes the cake as their Bluetooth contour series headphones come at $29.95. However, at the time of writing, it is currently sold out on their website. If this is an option you might consider, look into overall product availability through their customer service.

  1. BedPhones: Finding comfortable earbuds for sleeping is a challenging process. Now, the BedPhones does not feature a comfortable headband design but do feature a more comfortable design than most earbuds designed for sleeping.

BedPhones are priced at $89.99 and feature a design that disappears as you place your head into the pillow. Ultimately, these are still an earbud design, and some users may complain that this simply will not cut it for sleeping.

  • BedPhones features a 30-day return guarantee, so if you aren't satisfied, just send them back!


At the end of the day, finding a perfect pair of headphones for sleeping is difficult. In all honesty, you can likely compare the process of dating. You have to look around a bit, try out pairs now and then, maybe even vow never to use some again, but ultimately, you'll find the one that works best for you.

If you are someone that likes a design that strays away from earbuds, then AcousticSheep's SleepPhones are likely perfect for you.

With a comfortable headband design and noise reduction capabilities, the SleepPhones can undoubtedly be the side-sleeper's best friend.

Just to avoid any potential consistency issues, make sure you inspect your pair and make sure its battery life works as advertised. Good luck and here's to a good night's rest!

  • Comfortable headband design
  • Perfect for side-sleepers
  • Speakers that work to reduce noise
  • Does not totally eliminate sound, alarms still audible
  • Multiple options to choose from
  • Speakers are not Bose quality, but this was expected.
  • Can get pricey
  • Lots of different parts on some models might require replacement which increases the cost
  • Sometimes has an unreliable battery or overall life-expectancy
