10 Best annoying alarm clocks 2025 in the United States

The Mesqool Projection Alarm Clock is designed with heavy sleepers and the hearing impaired in mind, featuring both a loud alarm sound and a powerful vibrating bed shaker. These features make it effective for waking up even the deepest sleepers without disturbing others in the room. The adjustable 180-degree projector allows you to display the time on the ceiling or walls, which is a handy feature especially if you don't want to strain to see the clock.

The large 7-inch LED display with adjustable brightness ensures that the time is always visible, and the dimming options help to reduce light disturbance at night. Additionally, the clock includes a USB charging port, making it convenient to charge your devices overnight. The snooze button is another practical feature for those who need a few extra minutes in the morning.

On the downside, the clock requires two AAA batteries for backup, which are not included. Also, while the clock offers many useful features, some users might find it a bit complex to set up initially. Its design and functionality primarily suit those who need a louder alarm or a vibrating option to wake up, making it less ideal for light sleepers. The Mesqool Projection Alarm Clock is best suited for bedrooms where a clear and adjustable time display is beneficial, and where powerful alarms are necessary.

The Peakeep Digital Clock is designed to cater to heavy sleepers and those with poor eyesight, making it a suitable choice for seniors and teens alike. One of its standout features is the very loud alarm sound, adjustable with five volume options to suit different preferences. This ensures it can wake even the heaviest sleepers without causing undue distress to lighter sleepers. The inclusion of a 9-minute snooze function is a handy feature for those who need a few extra minutes in bed.

The clock's six adjustable dimmer settings allow users to set the brightness of the large LED display to their liking, which is particularly beneficial for those with sensitive eyes or different lighting needs throughout the day and night. The mirror face design adds a stylish touch and can double as a makeup mirror, although this might be seen as a gimmick by some users. The dual power source capability, with both electric power and battery backup (4 AA batteries required but not included), ensures reliability even during power outages, preventing missed alarms. This is particularly useful for anyone with a busy schedule.

It should be noted that no batteries or plug are included with the purchase, which might be a minor inconvenience. The clock is user-friendly, with clearly labeled buttons and a comprehensive user manual, making it easy to set up and use. On the downside, the clock's plastic frame may not appeal to those looking for a more premium build quality. This clock is ideal for heavy sleepers, seniors, or anyone needing a reliable, easy-to-read, and loud alarm clock with adjustable brightness and volume settings.

The Peakeep Small Digital Alarm Clock is designed for users who want a compact, easy-to-use alarm clock with a strong wake-up call. Its large, clear digital display features big numbers that are easy to read from across the room, and it has six brightness levels including an off option, so you can adjust the light to avoid disturbing your sleep. The alarm sound is quite versatile, offering five volume levels ranging from 55 to 90 decibels, which should suit both light and heavy sleepers. A 9-minute snooze function gives you a brief extra rest if you need it.

The clock operates primarily via a plug-in power adapter, ensuring continuous use without worrying about batteries running out. However, it includes a battery backup (4 AAA batteries) to save your settings during power outages, but these batteries don’t power the clock otherwise. This means you must keep it plugged in for it to work. The clock’s small size (about 5.5 by 2.5 inches) makes it a good fit for bedside tables, desks, or travel, and its minimalist white design can blend into many room styles.

A potential downside is the reliance on a power cord, which limits placement flexibility compared to fully battery-operated clocks. Also, while the alarm volumes go quite loud, the sound type and tone are not customizable, which could matter if you prefer a specific alarm noise. This clock is a solid choice for anyone who needs a reliable, loud alarm with an easy-to-read display and adjustable brightness, especially if you don’t mind plugging it in and want a backup for power outages.
