About Audio Baby Monitors

If you are looking for the best audio baby monitor, the range of connectivity between the parent unit and the baby unit should be your top consideration. Before we go through the guides, let’s first review the basics. If you want to jump straight to the best audio baby monitors of 2020, you can click here.

November 2020 Update
This post is a revision of an article we published earlier in 2019. We updated this list to include new brands such as enhanced range VTech brands and replacing brands are no longer available

Audio baby monitor transmits sound signals that the baby is making in the nursery to the parent unit. Essentially, it gives a parent an opportunity to hear the sound signals of the baby without having to be in the room. In fact, the Lindberg kidnapping in the 1930s inspired the invention of an audio baby monitor in 1937. The baby monitors then relied on the electric circuit to transmit signals but current wireless audio baby monitors rely on different technologies such as DECT, FHSS, and Wifi to transmit the signals from the baby unit to the parent unit.

Sound-only baby monitors available in the market today have several features that differentiate them. In this list, we’ll go through baby monitors that we like the following features that made us add them to this list:

  1. Temperature sensors
  2. 2 parent units or 2 baby units
  3. Audio baby monitors with app
  4. Night lights
  5. Sound levels
  6. Belt clip
  7. Lullabies

We also review audio baby monitors of different brands such as VTech, Motorola, Fisher-Price, Samsung, Philips Avent, Hellobaby, Willcare, and DBPower, among others.

How We Ranked the Best Audio Baby Monitors

After analyzing 53 audio baby monitors available on the market in 2020, we came up with some key ranking factors that enabled us to narrow down on the best 15 audio baby monitors in the market. Below are what we used to rank them:

  1. Range: The range of connectivity for non-wifi audio baby monitors and for audio baby monitors that use wifi and app
  2. Number of parent units the audio baby monitor supports: Baby monitors with two parent units did better than those that only support one parent unit
  3. The number of baby units: Baby monitors that support 2 baby units essentially make them ideal for monitoring twins in two separate rooms and those with this capability scored better.
  4. Quality of sound: Audio baby monitors with high definition sound quality as well as good sound control level scored better than those with poor sound quality and poor sound control levels.
  5. 2-way Talk: sound-only baby monitors with reliable 2-way talk feature scored better than those that were not very reliable.

In addition to using the above-ranking factors, we also aggregated and analyzed more than 12,000 reviews from several parents (on several websites) and put in more than 50 working hours to rank all of them. We also engaged two experts that have worked directly with top audio baby monitor manufacturer, VTech.

Reviews of Best Audio Baby Monitors

1. VTech DM221: Overall Best Audio Baby Monitor with Two Parent Units

VTech DM221 is our overall best audio baby monitor in 2020 and it came top because of its quality crisp audio output. It made it to the top of this list specifically because of its low price (sells for under $30) and has been positively reviewed by over 7,900 parents who have rated it 4.4/5. 

While this is not the cheapest (or less than $20), you get great features that you’d want in a basic audio baby monitor and most importantly, super clear sounds. The features are below. It uses digital encrypted DECT 6.0 transmission technology that utilizes a 1.9 GHz, frequency band. As of March 2020, VTech DM221 is the 4th best-selling baby monitor on Amazon. The picture below shows the silver image of VTech DM221 which weighs 376 grams.

Why it emerged as the best audio monitor: 

This is the third year being on our best-audio monitor list and I personally believe it has won the hearts of thousands of parents because of the following: 

  1. Very High-Quality Loud Sounds and Vibrating Alerts: VTech DM221 has deep and loud sound compared to all its peers in this 2020 list. It has 5 levels that give you the flexibility to choose on a sound level you’re comfortable with. If you have any hearing impairment or just a heavy sleeper, rest assured that the sound will be clear enough to wake you up in your deep sleep. On top of that, you can set it so it vibrates and you never miss a notification. 
  2. Long-range: The range that is advertised by the retailer and manufacturer, VTech is 1000 ft. but tests done by various labs have shown its range to be extra long with a range of up to 1350 ft. making it one of the best audio baby monitors with long-range and comparable to VTech Enhanced DM1211 and DM1111.
  3. Portable because of a belt clip: VTech DM221 is very portable and it allows you to move around the house, thanks to its belt clip that you can attach to your belt. 
  4. Sound level indicator: Unable to hear? VTech DM221 has 5-level sound indicators that allow you to view the sound level if you’d rather see the level and mute the sound. This multi-notification feature gives you flexibility. 
  5. Night Light: The loop of the baby unit emits night light making the baby’s nursery as soothing to your baby as possible. While it does not have lullabies like other baby monitors with lullabies, this soothing night light goes a long way for the price you get this baby monitor
    Backlit display and volume control on the parent unit

The only downside is that it has fewer features compared to a few others on this list. We however really liked the quality sound. 

Despite the few features, VTech DM221 is currently the second best-selling baby monitor on Amazon shipping 4,373 units per month.

2. Willcare Digital Audio Baby Monitor: Longest Battery Audio Monitor

Willcare digital audio baby monitor came second behind VTech’s DM221 but is favorite for parents looking for a long battery-life baby monitor. 

In late early 2019, Willcare upgraded its Willcare digital baby monitor offering us the longest battery life and super high-quality HD Willcare baby monitor that came second in our list.

Willcare is the second-best audio baby monitor and it made it to our list mainly because it has a more reliable battery but has most other features you find in regular VTech monitor such as:

  • A night light which you can remotely control from the parent unit, 
  • VOX/Eco-mode baby monitor
  • Loud enough, up to 40 decibels (when crying) and clear for 10 decibels (when your baby is regularly breathing)
  • A very long battery life of up to 20 hours. 

Willcare audio baby monitor prides itself of ‘HD sound’, emphasizing its clear digital sound transmission. It also has talk-back features that allow you to talk to your baby with incredible clarity. This baby monitor is very affordable and that means it comes with a few features. For example, Willcare audio baby monitor does not have fancy features such as temperature display but it won because of its incredibly clear and compact digital sound. As of August 1, 2019, the Willcare baby monitor is the 17th best-selling baby monitor on Amazon. You can check its price on Amazon today here

Audio Baby Monitor Categories

Audio baby monitors can be classified by functionalities it has and below are the six categories of baby monitors we developed to assist parents as they narrow down on what’s best for them and their baby. 

  1. Audio Only Baby Monitors
  2. Audio Baby Monitors for Multiple Rooms/Multiple Receivers 
  3. Audio Baby Monitors with Movement and Sound Sensors 
  4. Audio Baby Monitors with Temperature Sensors
  5. Audio Baby Monitors with Two Baby Units (ideal for twins)
  6. Audio Baby Monitors with 2-way Communication

Audio Only Baby Monitors

Similar to the original analog baby monitors developed in 1930s, audio-only baby monitors transmit the sound/voice made by the baby. The original baby monitors were analog and had a lot of interference. The digital baby monitors use improved technology, mostly DECT 6.0, which is more secure and free from interference. Out top two audio, only baby monitors are relatively priced low as they do not have other functionalities such as the sensors. 

Types of audio baby monitors

The original Zenith Radio Nurse (original baby monitors of 1937), was an audio baby monitor that allowed parents and caregivers to hear the voice from the baby’s nursery. Technology has made it possible for parents to now listen and track other baby activities such as breathing, temperature, and/or noise levels.

Modes of audio baby monitors

There are four modes in audio baby monitors which are:

  • Sound only notification baby monitors
  • Sound, Vibration and Light Notifications monitors
  • Light only Alert Baby Monitors
  • Vibration alert baby monitors

How We Reviewed the Best Audio Baby Monitors

1. Sound clarity – Clarity of sound took the biggest weight among all the factors we considered. The technology influenced sound clarity and we noted that all baby monitors that use DECT technology have better sound clarity. 

2. Ease of use – Audio monitors are supposed to be the most basic of all baby monitors and we considered ease of use when reviewing each of the audio baby monitors. 

3. Signal coverage – Several audio baby monitors are known to have a very strong signal and we compared all of them in the field and in a house with walls. Our best baby monitor gave us a long range of 1350 ft in the open field and the worst range we got was 700 ft. Please note that we did not do the test in an enclosed space. 

4. Battery life – This is the period it takes the baby unit or the parent unit to run of out battery. From all the tested audio baby monitors, the range is 9 hours to 46 hours. Again, our consideration only took the time it actually took the battery to die from our testing and not the claim by the audio baby monitor manufacturer. 

5. Price – Our review of the 13 baby monitors considered their current price on Amazon. The price ranges from $18 to $129. Our review has carefully considered and weighted other factors more than the price as we emphasize on the audio features of the baby monitors. There are other baby monitor options if you wanted additional features.

6. Baby safety – We measured each audio baby monitors’ EMF at 6 ft and noted a range of 0.5 v/m to 3.11v/m

History of Audio Baby Monitors and Comparison Table:

Some 82 years ago (in 1937), the first audio baby monitor was invented yet it is still difficult to get your hands on the best audio baby monitor today. Despite the sound-only monitors being available and actually being very affordable, the biggest problem seems to be finding the best and perhaps knowing what or which is the best audio baby monitor among the 28 sets of audio monitors in the market in 2020 (Amazon sellers). You can also check our wifi and non-wifi video baby monitors.

This article has an exhaustive list of top-rated audio monitors which has been updated twice to reflect new audio baby monitors, specifically Willcare and enhanced VTech audio monitors that were released in Q2.

Before we go to the recommendations, let’s start with the basics to give you an idea of the history and how we rated our best audio baby monitors in the market.

As mentioned above, the first audio baby monitor, the Zenith Radio Nurse relied on an electric circuit to transfer audio signals from the baby unit to the receiver. There were no other features such as the features you find in some digital baby monitors such as two-way audio, temperature sensors, and extra long-distance transmission.

The innovations led to the emergence of analog audio baby monitors that relied on radio frequency instead of an electric circuit. Analog baby monitors had several problems with interference as it could pick up random sounds and relay it on the receiver. As an analog signal is being transmitted, it progressively and irreversibly degrades the signal-to-noise ratio resulting in poor quality audio in the parent unit. 

In 2020, the best audio baby monitors are digital baby monitors. Digital baby monitors have better audio quality and do not lose the signal quality as gets transmitted from the baby unit to the parent unit. Some of the best digital baby monitors that I like and some of the team here at BMC have used have some of all of the following features:

  • Voice Activation feature (VOX),
  • Long battery life – up to 20 hours,
  • Two-way talk feature,
  • Lullabies,
  • Temperature and humidity sensors,
  • Belt clip,
  • And of course, digital signal transmission,

Digital audio monitors are non-video baby monitors that encrypt sound signal in transit guaranteeing you 100% privacy. All of our best baby monitors in 2020 using digital transmission technology, both the wifi and non-wifi baby monitors.

Now that we know ‘digital’ is good in audio monitors, let’s explore what you look out for when buying an audio baby monitor:

  • Battery life: The battery life of your audio baby monitor is key. The earlier VTech audio baby monitors such as VTech DM111 which is currently the top best-selling audio baby monitor in 2020 is notorious for having a very short battery life. Some argue that you get what you pay for (it is the cheapest audio baby monitor). You can however clearly see from its 172 1-star ratings that over 50% of the complaints involve the poor batteries. (Update: The new Enhanced VTech DM1111 and VTech DM1211 have longer battery life).
  • Range/Connectivity: If you live in a large house or work in a farm/yard, you should consider the range of the audio monitor you are purchasing. The longest range currently available is 1500 ft. Most DECT audio baby monitors have an extra-long distance range. You may have read about a 2000 ft. range as the best audio baby monitors that appeared in many review lists in 2017 and 2018 but that monitor is no longer available and tests actually disclosed that it didn’t stand the test. 
  • The Number of Transmitter and Receivers: If you plan on using your audio baby monitor to monitor your twins, go for units that have two transmitters or baby units. In addition, if two users will be monitoring the baby/babies, you should go for an audio baby monitor that comes with two parent units.
