Jawbone Jambox (Best Value)
Battery life: 10 hours
A little smaller than a four-pack of butter, the Jambox is great for small rooms or travel. Pair it with your phone, PC, or tablet via Bluetooth, and any audio coming from your device is played through its speaker. The Jambox also works as a speakerphone for a smartphone, allowing you to pick up and hang up calls directly. The rechargeable battery alerts you when it’s running low.
