Compare Motorola AM24, PIP15-2 Multi, PIP12 Travel, PIP10, PIP11 and AM21 audio monitors

Six audio-only models, with different room plans

Motorola's AM21, AM24, PIP10, PIP11, PIP12 TRAVEL and PIP15-2 MULTI send nursery sound to a nearby parent receiver; none in these reviewed packages supplies camera video or phone viewing away from home. AM21 is the simplest, AM24 adds an information LCD, talk-back and temperature readout, PIP10 adds a muted-speaker sound indicator, PIP11 adds soothing and temperature features, and PIP12 TRAVEL centers on portability and a pouch. PIP15-2 MULTI is the family model here that documents two nursery feeds audible at once.

AM21: straightforward sound without documented talk-back

The AM21 standard U.S. package has one baby audio unit and one parent receiver. Its guide supports an adapter or optional AAA alkaline cells for the parent unit, but batteries are not included and the manual does not specify a battery runtime or in-unit charging. Motorola's store description advertises sound-activated lights when the receiver volume is lowered; the detailed guide does not explain the alert threshold. Its 1,000-foot figure is an advertised maximum, not a documented line-of-sight or indoor test result. Choose it if your essential need is a local sound feed with adjustable volume, not a battery-hour or range threshold.

PIP10: a simple receiver with explicit battery guidance

PIP10 carries sound from one included baby unit to its compact parent receiver. A light flashes when a loud sound is detected while the parent speaker is muted. The receiver may use its adapter or two AAA batteries that are not included; its guide allows rechargeable NiMH cells and states up to ten hours of use, varying with cell type and capacity. The receiver does not charge those cells. The guide gives up to 300 metres line of sight and up to 160 feet indoors; Motorola’s U.S. page rounds the longer figure to 1,000 feet. Neither number predicts reception through your walls.

PIP10 does not document talk-back or a temperature readout. If you ask the finder to require talk-back, the PIP10 should drop out rather than borrowing that feature from PIP11 or PIP12. It remains a reasonable comparison when one-way sound is enough and you want the more detailed battery and placement instructions.

PIP11: more information and bedtime controls

PIP11 adds parent-unit talk-back, a backlit LCD with room-temperature information, five lullabies and a night light on the baby unit. It ships with two rechargeable AAA NiMH cells for the parent receiver; the guide estimates up to ten hours of use or fifteen hours of standby under ideal conditions. Holding the talk-back control pauses listening to nursery sound until you release it. Its LCD shows information, not video. Those extras matter if a temperature readout or light is useful; they do not add a camera or remote phone access.

AM24: an information LCD, not a camera screen

The U.S. AM24 listing and its support page identify the same AM24 model and Ref 810036771269 even though the store URL ends in /am23. Its standard package has one baby unit and one parent receiver. The 1.5-inch black-and-white LCD with orange backlight can show temperature and status, but it cannot show a picture. Motorola says one baby unit can connect to two parent units; that lets two caregivers use receivers, not hear two nursery feeds.

AM24 adds parent talk-back and a temperature reading without the PIP11’s documented night light and lullabies. Its manual estimates up to 10 hours of use or 15 hours standby in ideal conditions after an initial 16-hour charge; these are manufacturer figures, not measured results. The optional loud-sound beep is off by default, and the guide gives no threshold. Motorola advertises up to 1,000 feet, but the guide supplies no numeric open-space test protocol. The U.S. listing was sold out at the 2026-10-23 observation, so availability may differ. If your need is a local audio receiver with information but no camera, AM24 can fit; if you require two rooms at once, choose PIP15-2 MULTI instead.

PIP12 TRAVEL: two-way talk in a portable rechargeable pair

PIP12 TRAVEL is also audio-only but adds two-way talk, four supplied rechargeable AAA NiMH cells across the two units, two USB-C adapters and cables, and a water-resistant drawstring travel pouch. Each unit uses two cells. The English U.S. guide asks for a 16-hour first charge and says both units need their cells installed even when powered by the adapters. The magnetically joined pair must be separated before use and while charging; Motorola’s support description says the magnetic design powers the units off when joined for storage.

The guide specifies up to 450 metres (1,500 feet) outdoors with clear line of sight and says obstructions reduce range significantly. It describes up to ten hours of use under normal conditions, not a guarantee for every battery age, volume setting or trip. Five volume levels, mute, a red flashing sound-alert LED while muted, low-battery and out-of-range indicators, and hold-to-talk make it a more capable travel pair than a bare speaker receiver. No video screen, temperature display, or phone feed is documented.

PIP15-2 MULTI: one receiver can hear two rooms together

The U.S. PIP15-2 MULTI kit includes two baby units and one parent receiver. In its manual, the parent can listen to all connected units at once, focus on one, or cycle through them in 15-second turns. Cycling listens to one selected feed at a time; select all when two rooms need to remain audible together. The small LCD displays status and temperature, not camera images, and the direct local DECT link does not need Wi-Fi or an app.

Talk-back, temperature readouts/alerts, lullabies and adjustable night lights are also documented. The temperature alert thresholds are shared across units rather than tuned separately for each room. With two baby units, the manual estimates about nine hours of parent-unit battery use. The guide specifies up to 1,500 feet outdoors with line of sight, but the exact U.S. listing also has a 1,000-foot specification block; neither figure is a test of indoor reach. Choose PIP15-2 when audio from two rooms at once is the deciding need; if both rooms must be seen, compare a video system such as the DXR-8 PRO SS. Read the PIP15-2 MULTI assessment for its operating and charging details.

Match the essential need to one actual arrangement

In the finder, selecting audio-only keeps all six models in consideration. Requiring talk-back removes PIP10 and AM21; requiring a temperature display retains PIP11 and PIP15-2. PIP12 TRAVEL adds the travel pouch, while PIP15-2 is the two-room option. Its 1,500-foot manual maximum is not the same as an indoor result, and the U.S. page's lower specification block adds a reason not to treat either number as guaranteed reach.

The AM21, AM24, PIP10, PIP11 and PIP12 TRAVEL reviewed packages each include one baby unit and do not document two feeds at once. AM24 can connect one baby unit to two parent receivers, but that is not a second room feed. PIP15-2 does, when its all-units mode is selected; its cycling mode still alternates rooms. A second parent receiver is not a second baby unit. If two pictures are essential, choose a video system whose exact supported arrangement displays both rather than mistaking the PIP15 LCD for a camera view.

Keep placement and charging in the plan

Follow each exact manual. Keep baby units and cords out of the cot and more than one metre from the child; check the parent-to-baby separation and power directions for your model. Test the radio link from the receiving location you expect to use. A consumer monitor is an aid, not a substitute for responsible adult supervision. Read the detailed reviews for the AM21, AM24, PIP10, PIP11, PIP12 TRAVEL and PIP15-2 MULTI before choosing the routine that fits.
