The waterproof XSound Go’s clear and loud sound, compact size, and 10.5-hour battery life made it stand out among the budget Bluetooth speakers we tested.

If your New Year’s resolution is to try to unwind, Calm is offering new users 50% off a 12-month Premium subscription.

Premium subscribers can also access a few other bonuses, like sleep guidance and ambient music. This deal is only available to new subscribers.
