Buyer’s Guide

As smartphones have completely taken over alarm clocks’ responsibility, traditional bedside clocks are on the brink of extinction. However, many brands have since evolved these clocks into multi-functional gadgets replacing chargers, Bluetooth speakers, and radios instead.

If you’re in the market for a great, fully dimmable alarm clock, you’re bound to come across thousands of different options. However, here are some of the most important factors you should consider when choosing your bedside alarm clock:

Alarm Options

One of the best advantages of owning a good bedside alarm clock is the possibility to tweak the alarm to your needs. You can change the snooze gap, select how long the alarm will sound, and even choose increasing alarm intensity with some clocks. The possibilities are almost endless and will allow you to tweak your alarm system exactly to your liking.


Nobody wants to blind themselves by looking at their gleaming alarm clock in the middle of the night. That’s why it’s important to have full control over your clock’s brightness so that it doesn’t interfere with your sleep.

Many clocks offer full dimming like a smartphone display with the help of a dimming wheel, helping to set the brightness exactly as you like according to your preferences or time of the day. .

Extra Features

Alarm clocks are becoming very versatile gadgets with varying features depending on the model. You’ll often find alarm clocks with USB ports, FM radio, and Bluetooth connectivity. Some will even have wireless chargers and good-quality speakers integrated into the clock.

While you probably won’t need every single feature, a couple of extra USB ports and a wireless charger won’t hurt, especially when you lack extra wall sockets. Also, look for clocks that have a backup power option, such as AAA batteries.


Which display color is best for alarm clocks?

The best colors for alarm clocks are red, amber, orange, and all warm colors. Some alarm clocks might give off blue light, which can mess with your sleep cycle.

Why isn’t my alarm waking me up?

When you get used to a particular alarm tone, it becomes difficult to wake up when it rings. Keep changing the tone periodically so that it alerts you correctly and wakes you up on time.

What is the best alarm tone?

Studies have shown that melodic and chiming alarm tones reduce morning grogginess compared to ringing and beeping tones.

Should you snooze or wake up?

Snoozing can allow your brain some relief from abruptly waking up. However, it might not be as helpful when you’re hitting snooze from sleep deprivation and go right back to sleep.

Do increasing volume alarms help?

Yes, increasing volume alarm systems help wake you up more gently so that you do not have to suffer from grogginess in the morning.
