Highlights

  • Resonant 2.1 Bass-Reflex Subwoofer: Built with a premium, acoustic-grade medium-density fiberboard (MDF) wooden subwoofer cabinet. The targeted wood composition eliminates internal cabinet resonance, throwing out deep, warm, and undistorted low frequencies.
  • Untethered Bluetooth Streaming: Integrated with an upgraded, low-latency Bluetooth receiver module. Effortlessly stream your high-fidelity playlists, podcasts, or mobile games directly from your smartphone, tablet, or laptop from up to 10 meters away.
  • Vibrant Cycling RGB Accent Lighting: Enhanced with automated multi-color RGB illumination embedded into the driver rings of the subwoofer and satellite units. The lighting transitions smoothly through fluid gradients to add an active, colorful dimension to your desktop.
  • Dual Physical Dial Controls: Take total command of your sound profile via an accessible front-facing control panel. Dedicated tactile adjustment knobs allow you to fine-tune the master volume and dial in structural sub-bass thump on the fly.
  • Multi-Source Audio Playback Host: Features independent, built-in USB Type-A and TF (MicroSD) memory card slots on the back chassis, allowing the system to act as a standalone media player that decodes digital MP3 audio files directly without a computer attached.
  • Universal 3.5mm Aux Input: Outfitted with a gold-plated 3.5mm auxiliary cable connection that links directly to desktop gaming computers, televisions, projectors, and physical audio mixers for a rock-solid, latency-free wired signal.
  • Clean USB-Powered Mobility: Designed to operate entirely on a standard DC 5V USB bus-power configuration. It connects seamlessly to your computer's rear I/O panel or a traditional phone charger block, minimizing cable clutter behind your workstation desk.
Upgrade your home multimedia layout and experience deep, immersive acoustics with the Kisonli U-2900BT Bluetooth 2.1 Speakers. Combining a resonant wooden subwoofer chassis, quick wireless Bluetooth pairing, front-accessible tuning knobs, and a lively cycling RGB environment, this versatile multimedia sound system delivers the ultimate balance of heavy, room-filling sound and modern desktop versatility.

All products—including Brand New, Open Box, and Used items—are subject to the same warranty conditions, inspection standards, and exclusions outlined in this policy.

Open Box and Used items receive the same manufacturing-defect coverage as Brand New items. However, they may have a shorter designated warranty period, as specified on the product page or purchase invoice.

Power Protection Requirement

Due to extreme grid-voltage fluctuations ranging from 180V to 250V, all systems, individual components, and electronic devices must be powered exclusively through a verified, high-quality Uninterruptible Power Supply (UPS).

Failures or damage caused by the following are strictly excluded:

  • Power spikes or electrical surges
  • Brownouts or unstable voltage
  • Physical or accidental damage
  • Liquid exposure
  • Improper handling or misuse

These exclusions apply to products in all conditions, including Brand New, Open Box, and Used items.

Strict No-Tampering Policy

Opening or disassembling any device—including user-accessible hardware such as custom PCs, pre-built PCs, laptops, graphics cards, and power supplies—will immediately void the warranty.
