bluetooth speaker sd card slot

Most models offer Bluetooth plus multiple wired inputs: USB and TF/SD (microSD) card slots for direct playback, a 3.5mm AUX input, and line-level inputs such as RCA. Some models also provide mic and instrument jacks.

Many units include a microphone input and either come with a wired mic or support a wireless mic. This makes several models suitable for karaoke or basic PA use.

Common connections include 3.5mm AUX and RCA line inputs, and pro-style jacks such as XLR and 1/4" (6.35mm). Many models offer multiple connection types to support varied audio sources.

Listings commonly mention tripod or pole sockets and tripod mounting holes; some models or packages include speaker stands. Carry handles and strap/rigging points are occasionally listed for mounting or placement.

Playtime varies by model and usage. Listed runtimes in this set range from about 1.5 hours up to 4–6 hours, with many listings citing roughly 3–5 hours on a full charge.

Sizes span small to large (heights from about 7" up to ~41.75") and weights from roughly 0.5 lb to 44 lb. Common portability features include carry handles, hard-mounted handles, wheels or rolling designs, removable/adjustable shoulder straps on some models, and tripod/pole-mount sockets.

Many speakers list colorful LED panels and music-reactive light shows that pulse or change to the beat. Other described effects include multi-layer reactive patterns, top-mounted projection domes, and named show modes (for example a “FIRE” light show).
