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 CLOCKY Extra Loud Alarm Clock is designed for heavy sleepers who struggle to wake up in the morning. Its standout feature is its ability to jump off your nightstand and roll around the room, forcing you to get out of bed to turn it off. This makes it particularly effective for those who tend to hit the snooze button repeatedly. The alarm is extremely loud, ensuring that even the deepest sleepers will be jolted awake. However, the volume is not adjustable, so it may be too intense for some users.

The clock has a snooze function, but you can choose to disable it if you need an extra push to get up. The LED display is clear and easy to read, though it may be too bright for some people when trying to sleep. CLOCKY runs on 4 AAA batteries, which are not included, so you'll need to purchase these separately. This can be seen as a downside for those who prefer rechargeable options. The clock is lightweight and compact, making it easy to place on most nightstands.

It's also a fun and quirky gift for both adults and kids, especially those in need of a humorous and effective wake-up solution. While it's a great fit for heavy sleepers, its loud noise and mobile antics might not suit light sleepers or people who share a room. Additionally, the need for frequent battery replacements could be inconvenient for some users.

The Sonic Alert Sonic Bomb Dual Alarm Clock is designed for heavy sleepers, featuring a 113dB extra loud alarm with adjustable volume and a bed-shaking unit to ensure you wake up. The alarm clock is ideal for students or anyone who struggles to get up in the morning. It includes adjustable alarm duration (1-59 minutes) and snooze time (1-30 minutes), allowing customization based on your needs.

The vibrating unit can be set to vibrate, buzz, or a combination of both, providing flexibility in how you wake up. The large digital display has a five-level dimmer, making it easy to read without being too bright at night. The clock is powered by a corded electric source and includes a battery backup, ensuring it works even during power outages.

The clock's plastic frame and simplistic design might not appeal to those looking for a more stylish bedroom accessory. Despite these minor drawbacks, the Sonic Bomb is a reliable, effective solution for heavy sleepers and those with hearing difficulties.
