Update: This deal ended at the end of the day it was posted.
It’s a wireless speaker meant to be used outdoors. It’s water-resistant up to 1 meter and shock and dust resistant as well. The battery gives up to 15 hours of playtime, and you can even use it to charge your phone if you want to risk losing some time listening to that sweet sound.
If you’re in a more public space and need to listen to your music privately (Please, Mr. Subway Guy With His Phone On His Lap?), these Anker SoundBud headphones are down to $18 from $30. They connect through Bluetooth, can work up to 33-feet away from the source, and come with an 18-month warranty.
