What Buyers Say

4.0 ★★★★★32 Amazon ratings

👍 Pros

Equipped with Bluetooth version 5.0, offering stable and potentially extended device range when paired with a compatible phone.
Features a built-in 12-hour rechargeable battery, providing ample listening time for extended enjoyment.
Boasts an IP66 dust protection and waterproof level, making it highly suitable for outdoor and active use.
Supports TWS (True Wireless Stereo) function, allowing connection of two speakers simultaneously for enhanced audio output.
Includes a built-in Micro SD slot, offering an alternative audio playback option directly from a memory card.

👎 Cons

The TWS function requires purchasing two speakers separately, increasing the total cost if stereo sound is desired.
The total 5W RMS output, while adequate for portable use, may not be powerful enough for large gatherings or open outdoor spaces.
The listed features do not specify if a charging cable is included or the type of charging port (e.g., USB-C, Micro USB).
While waterproof, the IP66 rating means it can withstand strong jets of water and dust, but it is not designed for submersion.
The speaker's device range can double with a Bluetooth 5.0 phone, but the base range without this optimal pairing is not specified.
