Bose may be best known for its QuietComfort headphones, but the brand’s Bluetooth speakers have earned a great reputation for featuring great sound and build quality. The compact Bose SoundLink Micro — its most compact Bluetooth speaker — is currently discounted to $79.99 at Amazon, a pretty great discount from its usual $129 price tag.

The rounded-off square speaker is almost pocketable, and easily slides into a purse or backpack; it’s just over four inches wide, 1.54 inches deep, and weighs less than a pound. It’s dustproof and waterproof, with an IP67 rating that matches the larger Bose Bluetooth speakers, and should last a full day at the beach or by the pool. The speaker will run for up to 12 hours on a single charge, and has convenient nylon strap for attaching it to your backpack or to your bike’s handlebars.
