Pros and cons

Pros

Two wireless microphones and playback connections are listed, so a basic karaoke setup does not rely on buying microphones separately.
At a listed weight of 1.98 kilograms, it is a compact option for moving between rooms or taking to a gathering.
USB and microSD playback can be used without streaming music over Bluetooth.

Cons

The speaker’s battery life is described as up to three hours, which may limit longer sessions away from a power source.
The listing does not provide verified sound measurements or independent performance testing.

What to know before buying

The description says to avoid pointing a microphone directly at the speaker to reduce feedback. It claims up to 10 m/33 ft microphone signal range and up to 4 hours per microphone charge.

Listing details to confirm

Battery claims conflict: one feature says 3–4 hours of speaker playtime, while the product description says up to 3 hours. The listing also differs between 1.9 kg and 1.98 Kilograms, and its model fields give SD-301S and SDRD-301S. Confirm the selected listing details if these distinctions matter. The title and connection details mention USB, AUX and TF or microSD playback, while the detailed description specifies USB or microSD playback and AUX input for a TV.

Customer-rating figures are mostly in the four- and five-star categories, with some three-star ratings. That offers a broadly favourable but not uniformly positive signal, and the small rating sample does not explain why people rated the product as they did. It cannot establish microphone reliability, sound quality or actual battery life, so buyers should treat the conflicting runtime claims separately.
