Which sounds better, the Flex or the Plus?

The Plus. Its 2.5-inch woofer and rear-facing subwoofer give deeper bass and more volume. The Flex sounds good for its size but cannot match the low end.

Is the SoundLink Plus worth $59 more?

Yes if you want bass, 20 hours of battery and phone charging. At $120.00 the Flex is the better value for casual outdoor use.

Which is better for the beach or pool?

Both are IP67, so either handles water and dust. The Plus is heavier and easier to keep track of; the Flex floats less conspicuously and packs smaller.

Can I pair two of them for stereo?

Yes. Two Flex speakers pair for stereo. Two Plus speakers pair in Party Mode, which plays the same audio from both rather than left and right channels.

How long does each battery last?

The Plus is rated up to 20 hours and charges in about 5 hours over USB-C. The Flex runs about 12 hours.

Does either have a microphone for calls?

No. The Plus has no microphone, and the Flex is a speaker only. Neither takes calls or voice assistants.
