Bedroom Bluetooth Alarm Clock

This Samsung A21-B alarm clock pairs with your phone over Bluetooth 5.0 to set the time automatically. Dual alarms and a large snooze button let you wake on your own schedule. Six brightness levels and an RGB night light adapt the display to any bedroom.

For light sleepers and phone sync fans

It suits anyone who wants automatic time sync, two independent alarms and a colour night light in one compact unit. Buyers who need wireless phone charging or a battery backup for power cuts should look at other models.

Bluetooth 5.0 audio streaming

The single spec that decides fit is Bluetooth 5.0 connectivity, which enables wireless music playback from a phone or computer alongside the alarm functions. Without Bluetooth 5.0 this clock cannot stream audio wirelessly.
