Sharp Big Bang 115dB Extra-Loud Alarm Clock for Heavy Sleepers — Dual Alarms & Battery Backup

The Sharp Big Bang 115dB Alarm Clock is an extra-loud bedside alarm engineered to reliably wake heavy sleepers with a choice of six high-impact sounds and dual alarm settings.

If standard alarms and phone alerts aren’t getting you up, the Sharp Big Bang offers a purpose-built solution: a clock that prioritizes volume, sound variety, and fail-safe backup so you don’t miss work, travel, or early commitments. It pairs a very loud 115dB alarm with a large LED display and battery backup, giving you visible timekeeping plus audible assurance even during power interruptions.

How does the Sharp Big Bang make waking easier for deep sleepers?

The Big Bang is designed to cut through deep sleep by delivering an alarm level far higher than typical clocks and phones. Its six aggressive tones are selected to disrupt sleep cycles and force alertness, while the adjustable brightness and simple controls minimize frustration in low light.

• 115dB maximum alarm output—significantly louder than standard alarms
• Six distinct wake sounds like Rooster, Siren, Jackhammer, and more
• Large white LED display with dimmer to avoid nighttime glare
• Simple buttons for quick alarm setup and snooze

What alarm features help manage different schedules?

This model includes dual independent alarms so you can set separate wake times for weekdays and weekends or keep a backup time as insurance. Battery backup stores your alarm settings during outages so you won’t lose configured times if the power goes out.

• Two independent alarm settings for flexible scheduling
• Battery backup (2 x AAA, not included) preserves settings during power loss
• Easy-to-use on/off and snooze controls for quick changes
• Compact footprint fits on standard nightstands and dorm desks

Which wake sounds are available and when should I use each?

The Big Bang offers six high-impact tones designed to appeal to different sensitivity levels and environments. Choose a penetrating sound like Siren or Jackhammer for the deepest sleepers, or use Bugle or Rooster for a rousing but less abrasive start.

• Rooster and Bugle: sharp, attention-grabbing tones for gradual awakenings
• Siren and Jackhammer: intense, high-energy alarms for the heaviest sleepers
• Beep and Nagging Voice: simple repetitive cues for consistent wake prompts
• Quick switching between sounds to find the most effective tone

How visible and user-friendly is the display at night?

The oversized white LED display shows the time clearly across the room and includes a dimmer so the light won’t disturb sleep. Controls are plainly labeled and reachable, making it easy to set alarms or change brightness without fumbling in the dark.

• Large, high-contrast white LED numerals for easy reading
• Adjustable brightness to reduce nighttime glare and maintain comfort
• Accessible control layout for fast alarm configuration
• Durable design suited to dorms, bedrooms, or shift-worker setups

Who is this for? The Sharp Big Bang 115dB Alarm Clock is ideal for adults, teens, students, and shift workers who consistently sleep through phone alarms or quieter clocks. It’s also a practical choice for travelers and anyone who needs a dependable, loud backup alarm with straightforward controls and visible timekeeping. If you want a no-nonsense, purpose-built clock that prioritizes getting you up on time, this model is engineered for that role without complicated features.
