Sharp Big Bang Super Loud Alarm Clock — 115 dB, 6 Tones, Dual Alarms & Dimmer (Black)

The Sharp Big Bang is an ultra‑loud bedside alarm clock designed to wake even heavy sleepers with up to 115 dB and six adjustable tones.

Engineered for people who struggle with light alarms, the Sharp Big Bang combines extreme volume with customizable tones, dual alarms and a flexible snooze to ensure you get up on time. It’s a plug‑in bedside clock with battery backup for saved settings and a three‑step dimmer so the display won’t disturb your sleep. The unit gives straightforward controls so you can tailor alarm volume, tone and snooze duration without digging through complicated menus.

How loud is the Sharp Big Bang and will it really wake me?

The Big Bang reaches up to 115 dB at maximum, far louder than most bedside clocks and comparable to industrial or emergency warning levels. You can adjust both volume and pitch to create a sound profile that cuts through heavy sleep or noisy environments.

• Maximum volume: up to 115 dB for high‑impact waking
• Six distinct tones you can mix and match
• Volume and tone controls let you find the most effective alarm

What alarm sounds and customization options are available?

The clock includes six different wake sounds—Rooster, Bugle, Nagging Mom, Jackhammer, Siren and Loud Beep—so you can pick the one that motivates you best. Each sound’s volume and tone are adjustable, and the dual alarm setup supports two independent wake times for different schedules.

• Six selectable sounds for varied wake experiences
• Dual alarms for partners or staggered schedules
• Customizable snooze from 1 to 59 minutes, default 9 minutes

How does the clock behave overnight and during power interruptions?

The Sharp Big Bang runs from a standard 110V/120V wall outlet so the digital display remains bright while powered. If power is lost, two AAA batteries (not included) preserve the time and alarm settings; the display won’t be lit during battery backup but your alarms and time will be retained for when power returns.

• Electric operation for continuous display and alarm performance
• Battery backup stores settings during outages (2 x AAA required)
• Display remains off on battery backup to conserve power

Can I reduce display brightness so it won’t disturb sleep?

Yes—the Big Bang offers a three‑step dimmer so you can choose Off, Low or High display brightness. That lets you keep a visible clock without harsh light shining across the bedroom at night.

• Three brightness levels: Off, Low, High
• Quick control for bedside adjustments
• Helps reduce light pollution while keeping time visible

Who is this for: The Sharp Big Bang is ideal for heavy sleepers, deep nappers, shift workers, roommates with different schedules, and parents who need a reliable, loud alarm for children. If you need a straightforward, powerful alarm with customizable sounds, dual alarms and practical battery backup, this clock provides a no‑nonsense solution for consistent wakeups.
