Short answer: the Soundcore Boom 3i for better sound quality, the Xiaomi Sound Outdoor for the lower price. The Soundcore Boom 3i ranks #27 of 136 medium speakers at $110. The Xiaomi Sound Outdoor ranks #41 at $56.80, $53.20 cheaper.

The case for the Soundcore Boom 3i: Looks to be designed as a direct competitor to the Charge 5 with a very similar sound profile, warm tuned with boosted bass. The catch: Not quite as good as a Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close.

On the Xiaomi Sound Outdoor side: A pretty decent sounding speaker. Watch for: Boosted bass. Somewhat uncontrolled in the bass at high levels.

Pros: Looks to be designed as a direct competitor to the Charge 5 with a very similar sound profile, warm tuned with boosted bass. Better value for the money than the Charge 5.

Cons: Not quite as good as a Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close. An earlier firmware version had some bass distortion, update your firmware in the Soundcore App
