We tested how durable each alarm clock is by simulating what would happen if you accidentally knock it off your nightstand when you hit snooze or turn the alarm off. The Phillips alarm clock showed no signs of functional or cosmetic damage after falling onto carpet, hardwood and tile flooring. Its matte black side and back panels and the durable aluminum speaker grille on the front didn’t have visible scuffs or scratches after bouncing on the tile floor. More than half of the alarm clocks we reviewed were noticeably damaged during this test, particularly when they fell on the hardwood and tile floors.

To test the alarm clock’s maximum volume, we placed a decibel meter 2 feet from its speaker and played it at its loudest tone. The buzzer on this Philips alarm clock projected sound at 86.5 dB, which is the second loudest volume in our test and about as loud as city traffic. The clock has a progressive alarm, so it starts out about as loud as a normal conversation and works its way up to an ear-splitting volume until you hit snooze or turn the alarm off.


The AJT4400B uses two AA batteries as a backup to the AC wall plug. You have to purchase the batteries separately, but they are easy to install in the bottom of the device. The backup batteries save clock and alarm settings in the event of a power failure, but they don’t power the alarm, so it won’t go off during an outage. This is an important consideration if you live in an area with frequent blackouts.

There is a USB port on the bottom of the alarm clock’s back panel that you can use to charge mobile devices. That frees up a wall socket near your bed to charge or use other electronics.

Convenience Features

This is one of only two alarm clocks we reviewed that’s Bluetooth compatible, and you can use the connection to play music from your phone through the device’s speaker. The AJT4400B also has a sleep timer, which turns the music off after a set amount of time – you can adjust the timer between 15 and 120 minutes, depending on your preference.

You can also use the Bluetooth connection to make hands-free phone calls. This is one of only two alarm clocks we tested that has a microphone, speaker and button for answering, ending or rejecting calls. However, it doesn’t display the temperature or date, two pieces of information that could help you plan your day.

Alarm Options

You can choose to wake up to the sound of a buzzer or the radio. Fewer than half the clocks in our test group have a radio alarm option, and the Philips AJT4400B allows you to store up to 20 preset stations. That makes it easy to rotate your station of choice when you get tired of listening to the same talk radio program every morning.

The AJT4400B also has a dual alarm feature, so you can set two different wake up times. This is a valuable feature if you and your bedmate have different sleep schedules.

Help & Support

Philips offers a one-year warranty on this alarm clock, which is the industry average length. You can contact its support staff by telephone if you have any questions about the clock’s features.


The Philips AJT4400B is a valuable tool to have on your nightstand – in addition to being an alarm clock, it has a USB charging port and Bluetooth connectivity. Those new-school features, along with its traditional conveniences and better-than-average durability, make it one of the best alarm clocks for less than $60.
