Not everyone needs a fancy baby monitor with video, WiFi, and other bells and whistles. A sound-only baby monitor will suffice for most situations, and they tend to offer superior battery life, signal range, and portability.

If you're looking to save some money and willing to lose the video monitoring feature, we found some great options!

Just for fun, what does ChatGPT think is the best audio-only baby monitor!?
"After extensive research and gathering expert opinion, we have identified the Philips Avent DECT Baby Monitor as the top recommended audio-only baby monitor due to its clear sound quality, long battery life, and two-way talkback feature." -ChatGPT

Well, consider us impressed (and scared)! Maybe the robots are not so far off from taking over our business!

Here are the top 5 sound-only baby monitors for the year, followed by reviews of several options.

While we spend most of our time reviewing relatively fancy models for our best baby monitors list, testing these sound-only baby monitors was surprisingly fun! As it turns out, for under about $100 you can get an audio-only baby monitor with impressive quality and features.

To find you some great options, our hands-on tests considered 2 newly released models alongside 9 existing models from prior years. We tested them in big and small houses, indoors and outside, and on battery and plugged in; we tested battery life, sound quality, sensitivity, portability, and any special features.

Full disclosure: Some of these baby monitors, including the Babysense and Philips models, were sent to us as free test samples by the manufacturer.

Here are our Top Picks for Audio-Only Baby Monitors!

1. Philips Avent DECT Baby Monitor.

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 a fantastic range, coming in at about 1000 feet outdoors, and about 160 feet indoors (contingent on wall density). Other than the video, it has all the features you expect to see in a baby monitor including a two-way intercom, a nursery temperature monitor, a remotely controlled nightlight, and 5 different lullabies. 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 (like the next room over). A unique nighttime mode dims the parent unit and lets you customize the audio alerts, including turning them to vibration only.

In our testing, we thought it was super easy and intuitive to use, the reception was excellent, 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 sound-only baby monitor! The only downfall is the price, coming in at nearly $200. That's very steep for a sound-only baby monitor, and honestly, at that price you might want to consider a baby monitor with video (see the best baby monitors here). Who else loves the Avent DECT monitor? Our friends at Babygearlab and WhatToExpect also consider it a top pick! Impressed? You can check out the Philips Avent DECT Sound-only Baby Monitor here.

2. VTech DM221 Audio Baby Monitor.

This is one of three VTech baby monitors on this list, and this one comes in above the others 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 Avent and DM111 it uses the DECT 6.0 technology for digital transmission and 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 read a baby book at night or do a night-time feeding or diaper change.

Unlike the DM111, you can adjust the volume and sensitivity separately, which is a great feature to reduce the odds that a false alarm will wake you in the middle of the night. 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 bedtime. The 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 backyard). Overall, this is a great baby monitor, and is well worth the price at only around $40! Who else loves the VTech DM221? Our friends at Babygearlab, WhatToExpect, and The Bump also consider it a top pick! Impressed? You can check out the VTech baby monitor here.

3. VTech DM112-2 Audio Baby Monitor.

You've probably noticed that VTech makes a ton of sound-only baby monitors, and the DM112-2 is one of their most updated releases. For the new release, they added rechargeable batteries to the parent units, so now you can freely walk around the house without worrying about needing to plug it in. The basic DM112-2 includes one parent unit, or you can purchase it with two parent units. We prefer upgrading to two parent units for about $10 more, to give you the flexibility of placing the units around the house (for example, one in your bedroom, one in the living room), or having a backup for when you forget to charge one of them. One of the reasons that the VTech baby monitors are so great is that they are super simple, easy to use, and they last forever. The DM112-2 is no exception. Its basic features include DECT 6.0 encrypted digital audio with up to 1000 feet of range, volume control, belt clip, rechargeable batteries in the parent units, and a low battery indicator. The parent units also have a green-red LED sound level indicator. Outside of that, there's nothing to really set this unit apart: no night light, no adjustable sensitivity, no auto-off timers, no cry detection, no batteries in the base unit, and nothing else you might ask for!

In our testing, we found that it worked perfectly as expected: decent sound quality, decent volume control, decent indoor range, and decent battery life. When we first started testing it, battery life was about 8-9 hours, and then after a couple of months of use, it was about 7-8 hours. There were some periods of time when the parent units would randomly produce white noise for a couple of seconds, but those were rare. Overall, we think this sound-only baby monitor does a great job and offers great bang for the buck. It's typically a bit less expensive than the DM-221 (above), and a bit more expensive than the DM-111 (below), which you would expect given the feature sets. Interested?

4. VTech DM111 Audio 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 background noise. It is a basic baby monitor with adjustable volume, a sound level meter to indicate how much noise 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 humming noise 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 (about 8) 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 droning noise to it (which got a bit annoying), and the batteries in the parent unit are not rechargeable.

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 left it plugged in most of the time, so it didn't eat through batteries too quickly. Overall, this baby monitor offers good bang for the buck for parents looking to get something inexpensive, basic, and reliable. But for only about $5 more, we suggest upgrading to the DM221. Who else recommends this baby monitor? Our friends at Babygearlab and WhatToExpect consider it a top pick! Interested? You can check out the VTech DM221 here.

5. Hatch Rest+ Audio Baby Monitor.

What happens when you combine our best infant sound machine with a high-quality audio baby monitor? You get the amazing Hatch Rest+ system! Coming in at about the same price as the Avent DECT system, this system offers serious versatility. First and foremost, the Hatch Rest+ functions as an audio baby monitor with high-quality audio, two-way intercom, and secure communication. Second, it functions as a white noise machine with high-quality sounds, and includes a night light with a time-to-rise feature. In our testing, the sound machine and time-to-rise features worked really well. The night light had a customizable color, which is a nice touch. The Hatch connects to your smartphone using their app and your home's WiFi system, and we found connectivity to be relatively reliable.

The audio baby monitor feature seemed like a bit of an afterthought. It had a high latency (delay) for both hearing our child (we would hear his voice a few seconds before hearing it through the monitor), and also using the two-way intercom function. Also, when you have the sound machine feature active, you can't hear anything in either direction - just a bunch of static. Overall, we weren't super impressed with the Hatch Rest+, though we do think it makes a great sound machine! To our knowledge, only WhatToExpect recommends this system, though they may not have tested one of the newer models that use WiFi (the older ones used Bluetooth, which was much better!). Interested?

7. Babysense Hisense 7 Baby Monitor.

the babysense hisense 7 monitor

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. In our opinion, there isn't another system with the same reliability levels at a cheaper price. So if you're looking for just a movement monitor, this is a great option. Note that the Babysense sensors do not work well underneath memory foam crib mattresses, like the Milliard, which absorb too much movement-related energy.

7. Motorola PIP11 Audio Baby Monitor.

the motorola pip11 audio baby monitor

Motorola makes two ultra-compact audio-only baby monitors, the Motorola PIP10 and PIP11. The Motorola PIP10 is relatively bare bones: it has no screen and gives information (like low battery, mute indicator, and out-of-range alerts) via a series of small indicator lights. The Motorola PIP11 adds a small screen with several icon-based indicators such as signal strength, battery level, night light power, and more. For features, it also adds a nursery temperature monitor, sound detection alerts, a night light, and two-way talk, and includes rechargeable batteries in the parent unit. For about $40, that's a good set of features.

In our testing, we thought the Motorola PIP11 was a decent baby monitor with a limited feature set. The most ideal aspect of this audio-only baby monitor is the portability, offering the ability to wear the parent unit on your waist or throw it into a pocket. Of course, it also doesn't take up much space on the bedside table. The room temperature monitoring worked well and we liked the addition of the (very dim) night light. However, there were a few limitations. First, the baby monitor had a hard time picking up on nursery sounds until they were so loud that they likely would wake you anyway. To remedy this issue, you need to place the receiver very close to the side of the crib (we zip-tied it onto the inside of the crib; of course, you won't be able to do this once your baby starts exploring). Second, the parent unit also emitted an annoying beeping noise if the volume was too low or if the receiver was out of range, and its battery life wasn't great. Overall, we think you can do better for your money with a VTech unit, but this Motorola is worth considering if you're looking for superior portability.
