Overview
Sharp designed the Big Bang as a loud bedside alarm for heavy sleepers, with a selectable tone, a custom snooze and a dimmable digital display. A battery backup and a second wake time cover rotating shifts and power interruptions.
Volume and flexibility are the reasons to buy: a choice of sounds, an adjustable tone and an extra alarm slot suit uneven schedules. Details such as display size, snooze length and the backup battery type are missing from the listing.
Who it's for
Deep sleepers, students in dorms and people on rotating shifts get the volume, tone choices and extra alarm time. Light sleepers, or anyone who wants a soft sound or light to wake up, should choose a quieter clock.
Pros and cons
- Very loud alarm output
- Choice of sounds with adjustable tone
- Second wake time for shifts
- Custom snooze setting
- Display size and power source not listed
- Loud output unsuited to light sleepers
- Dimmer offers only three steps
Performance notes
Volume is set by the alarm output rating, and the adjustable tone changes how the sound cuts through deep sleep. The dimmer steps between off, low and high so the display does not light a bedroom at night. A backup battery lets the alarm survive an outage, though the listing gives no runtime.
