The Kisonli AC-9002BT is a compact and versatile 2.0 channel multimedia speaker system designed to dramatically enhance the audio quality of desktop computers, laptops, and mobile devices . Whether you are listening to music, watching movies, gaming, or on a conference call, this speaker system provides a significant upgrade over standard built-in laptop speakers.

Versatile Connectivity
The 9002BT stands out for its multiple input options, allowing it to connect to almost any device .

Bluetooth 5.0: Stream wirelessly from your smartphone, tablet, or laptop with a stable connection up to 10 meters .

AUX Input: The standard 3.5mm headphone jack allows for a wired connection to PCs, TVs, and older music players.

USB Playback: Play MP3 audio files directly from a USB flash drive.

TF Card Slot (Select Variants): Insert a MicroSD card to play your music library without needing a separate device .

FM Radio (Select Variants): Listen to your favorite local radio stations.

Dynamic RGB LED Lighting
The front of the speakers features dynamic, color-cycling RGB LED lights. These lights cycle through a spectrum of colors, adding a vibrant and modern aesthetic to any desktop setup. The visual feedback also serves as an indicator that the speakers are powered on .

Decent Audio Performance
Despite its compact size and budget-friendly price, the 9002BT delivers clear highs, balanced mids, and decent bass response. It utilizes dual drivers (size 5.2cm) with 4Ω impedance and low distortion (≤ 1%) to produce a sound experience suitable for various audio content . The frequency response range of 20Hz to 20kHz covers the full spectrum of human hearing.

USB Powered & Simple Controls
The system is powered via a standard USB connection (5V DC). You can plug it directly into a USB port on your computer or use a standard 5V/1A mobile phone charger (not always included, check the box). This eliminates the need for a bulky power brick. Volume is adjusted using an in-line scroll wheel located on the connecting cable, making it easy to reach without fumbling for a knob on the back of a speaker .

Ideal For:

Desktop Computers & Laptops: A perfect companion for any PC setup to improve audio for work and play.

Small Office Spaces: Provides clear audio for conference calls and presentations.

Bedrooms & Dorms: A space-saving design that fits easily on a desk or shelf.

Home Entertainment: Great for watching YouTube, Netflix, or streaming music.

Note: The specific output power (3W vs 5W per speaker) and the inclusion of features like the TF card slot and FM radio may vary slightly depending on the specific regional batch or sub-model. It is best to check the product packaging for the exact features before purchasing. The system requires a USB port for power; if your devices are limited, you may need a separate USB wall adapter.
