Best Sound-only Baby Monitors 2020

Be sure to also check out our reviews of the best baby monitors, all of which have video and/or wifi capabilities! We gathered 8 moms and dads and 11 different sound-only baby monitors, and put them through comprehensive hands-on testing. Each set of parents tried out 3 different baby monitors in their own home, testing sensitivity to noise and/or movement, clarity of sound, range, ease of use, and reliability.

We tested them in big houses, small houses (our own!), tall houses, and wide houses, to make sure we got a handle on how reception varies in different contexts. We pulled together all the reviews, compiled the results, and developed our best baby monitor list. Below we list the top 5 audio-only baby monitors, followed by our in-depth reviews.

Our recommended baby monitors are the easiest to use, have the clearest sound, and are highly sensitive to baby sound and movement. And they all have decent range. So you can carry the unit around with you in the house and even in the yard, and be confident that it will still let you know when your little one makes a peep. Some have added features, like movement sensors, and others are relatively simple. When finding the best baby monitor for your family, you want to make sure it's also reliable and uses secure communication. All of the baby monitors for this test were sound-only.

Here are the Best Audio-only Baby Monitors of 2020!

1. Philips Avent DECT Baby audio baby monitor philips avent dect

Coming in at #1, the Avent DECT is a fantastic baby monitor with an impressive set of features. The DECT technology provides the clearest and most reliable reception on this list, along with the peace of mind of high security and privacy. It also has fantastic range, coming in at about 1000 feet outdoors, and about 160 feet indoors. And other than video, it has all the features you're looking for, including two-way intercom, a nursery temperature monitor, remotely controlled nightlight, and 5 different lullabies you can play. The battery life was pretty good, coming in at up to 18 hours. It also has a battery saver mode (they call it ECO mode) that helps extend the battery life a bit, as long as the nursery is nearby. It also has a cool nighttime mode that dims the screen and lets you customize the audio alerts (you can also turn them to vibration only). In our testing, we thought it was super easy and intuitive to use, the reception was excellent and the sound was very high quality, and the temperature monitor was surprisingly accurate (we compared it to a digital thermometer). Another positive is that you can change the sensitivity of the microphone to ignore the relatively quiet whimpers and only activate for the louder squeals. Overall, this is an excellent baby monitor! The only downfall is the price, coming in at just over $100 which makes it very close to the price of an inexpensive video baby monitor. Interested?

2. VTech DM221 Audio Baby audio baby monitor vtech dm331 baby monitor

This is one of two VTech baby monitors on this list, and this one comes in above the other for overall features and functionality. In addition to the basic audio monitor functionality, it also includes a two-way intercom (so you can talk back to your baby, like a walkie-talkie), a vibrating sound alert (for when it's muted), a rechargeable battery in the parent unit, and a night light on the baby unit. Like the DM111 (below) it uses the DECT 6.0 technology for digital transmission and white noise reduction. In our testing, there were a few nice things to point out. First, we liked the big loops at the top of the baby monitor and parent unit, making them very easy to pick up and move around. There is also a belt clip on the back of the parent unit, since it's a bit large to fit in the pocket, you can put it right on your hip. Second, we loved the "page" function, which allows you to press the page button on the baby unit, which will make the parent unit beep until you find it (buried in the couch cushion). Third, we also liked the night light, which is nice for brightening things up a bit, for instance when you need to do a night-time feeding or diaper change. Unlike the DM111 (below) you can adjust the volume and sensitivity separately, which is a great feature to reduce false alarms that startle you awake with random pops of static. Finally, the rechargeable battery in the parent unit lasted for over 15 hours in our testing, which was pretty impressive. That means if you accidentally leave it on during a morning nap, it won't be dead by the afternoon. Range was decent in our testing, and it gives a beep to warn you when you're getting too far away (for us, that happened in the back yard). Overall, this is a great baby monitor, and is well worth the price at only around $30.

3. VTech DM111 Audio Baby audio baby monitor vtech dm111 baby monitor

Here is a super simple and inexpensive baby monitor with some decent features and high reliability. The VTech baby monitor uses the DECT 6.0 audio transmission for high sound quality and lower fuzzy white noise. It is a basic baby monitor with adjustable volume, a sound level beter to indicate how much sound is in your baby's room (even when it's on mute), and the parent unit has a belt clip. In our testing, we thought this baby monitor did a decent job for such a cheap option. It was sensitive enough without bringing in too much fuzz sound (there was a bit of a hum even on low volume), the range on the parent unit was pretty good (it worked upstairs and across the house, and in our small yard), and the batteries seemed to last several hours pretty long when unplugged. What we didn't like was that the volume didn't seem to go low enough, even at the lowest volume the speaker was pretty loud and had this subtle hum to it (which got a bit annoying), and the batteries in the parent unit are not rechargeable. So it eats through AAA batteries pretty quickly, ours lasted only about a week with normal use. Either buy stock in your favorite battery company, or go with a unit that has a rechargeable parent unit. We just leave it plugged in most of the time, so it doesn't use the batteries too much. Overall, this baby monitor offers good bang for the buck for parents looking to get something inexpensive, basic, and reliable.

4. Hello Baby HB180 Audio Baby audio baby monitor hello baby hb180 hb178

We were excited to get our hands on this sound-only baby monitor because it's only about 30 bucks and offers a lot of features, including DECT technology (same as the Philips Avent model), long range transmission, nursery temperature monitor, two-way intercom, lullabies, and a nightlight. For around $30 you aren't getting the highest quality baby monitor on the market, but you're definitely getting something that functions pretty well and will last you until you no longer need a baby monitor. In our testing, we found that the secure encrypted DECT transmission was impressive - it has really long range, into the backyard, across three levels (from basement to second floor), and from one side of a long ranch house to the other. The reception was basically the same as the $100 Philips Avent DECT model, but for about a third of the price. The battery life of the parent unit was just OK, coming in at about 4-5 hours when not connected to the charger. Unfortunately it doesn't use a basic USB charger cord, so you can't just plug it into your existing device chargers and use it in other areas of your home (kitchen, living room, etc). If needed, you can buy extra chargers for the parent unit though - here is one that we know works, though there might be cheaper ones available online. The temperature monitor actually seemed pretty accurate, and the two-way intercom worked just fine (and it has adjustable volume). The clarity of the sound wasn't great, and the volume adjustments were somewhat limited. The lullabies didn't sound great and the nightlight was super dim, but then again it's only about $30 for this thing. We need to keep reminding ourselves of that price point, because it justifies some of the short-comings of this baby monitor. Overall, here we have a lot of features for the price, but the overall quality of the rechargeable battery and sound leave something to be desired. Note that Hello Baby also sells an even less expensive version of this, the HB178, that drops the temperature monitor, rechargeable battery, and lullabies, but also drops another $5 in price.

5. Summer Infant Baby Wave Baby audio baby monitor summer infant baby wave

If you thought the Graco was simple, then you'll be in for a surprise. This Summer Infant baby monitor is even simpler (and cheaper!). Like the Graco (below), it does sound only and also has a little indicator light that goes from green to yellow to red to indicate the intensity of your baby's noises. Our parents who tested this system were mixed in their reviews. Some of them noted that they got a lot of interference in spite of the system's claims to be digital and interference free. They also noted that the shape is a little awkward to carry and stand on end, and the range isn't quite as good as with our top two options. Overall, this is a decent little unit with some limitations you should be aware of. But for the price, it might be worthwhile? 

6. Babysense Hisense 7 Baby audio baby monitor babysense

This unit is a bit different from the others because it doesn't default to tracking sound only and then add a bunch of random features, it's really designed for the parents who are only concerned about tracking movement. This Hisense baby monitor tracks movement only, not the sound of your baby. Using two super thin sensor pads placed under your baby's mattress, it detects even very subtle movements and alerts you through the receiver. If your baby doesn't move for 20 seconds, or no micro-movements are detected for 10 seconds, the device will sound an alarm. This is the system for parents who are worried about SIDS, particularly in preterm babies. With all the dangers facing infants during their early stages of development, our testers noted that this was a great idea. They also noted that it worked quite well, but they weren't convinced that it was worth the high price. Instead, they said they would have opted for the Angelcare. We agree with this sentiment, but also point out that other parents noted that this system was more sensitive and reliable, and had fewer false alarms. So if you're looking for just a movement monitor, this is a great option.

7. Angelcare Movement and Sound audio baby monitor angelcare movement monitor

This combines the best features of an audio baby monitor with an awesome movement tracking monitor. The blue pad goes under your baby's mattress and is able to detect even the most subtle of movements. The microphone device detects breathing sounds and any other noises your baby makes, and those are indicated as movement lights on the receiver unit even if you turn off the sound. The system will trigger an alarm if it does not detect anything for 20 seconds; our tester parents who had a premature baby really loved this feature as it reduced their worries during the night. The full color digital display also shows the temperature in your baby's room to give you confidence that it's not too hot or cold during the night. The receiver unit is portable and automatically recharges when placed in the convenient cradle by the side of your bed. Our parents noted that its range was very long, the sound quality was high, and they loved the extra features (temperature monitor, movement monitor). So there are a ton of great things going for this baby monitor. The cons? Some of our parents mentioned that it was a bit complicated in terms of its lengthy feature list, and another mentioned that it tended to false alarm a lot so they had to turn down the sensitivity of the pad. Overall, parents were very positive about this unit. The biggest challenge at this point is that Angelcare released a new model and it doesn't perform anywhere near as well as the old one. We found it online for about $80.
