Overview

The kstime ST702 is an entry-level USB-powered gaming speaker that connects via a standard 3.5mm audio jack. It delivers 4W of stereo sound through a full-range 2.0ch driver setup, making it a straightforward upgrade from built-in monitor or laptop speakers. The built-in RGB lighting cycles through six colors in sync with music, adding a subtle gaming aesthetic to your desk. Setup is truly plug-and-play: no drivers required. Just connect the USB cable for power and the 3.5mm cable to your audio source, and you are ready to go. Priced around ¥3,500, it is one of the most affordable ways to get external speakers for a PC, TV, or tablet.

Connectivity & Compatibility

The ST702 uses a USB-A port for power and a 3.5mm stereo mini-jack for audio input. It works with Windows (Vista/7/8/10), macOS, Chrome OS, Linux, and UNIX systems. It can also be used with TVs, laptops, tablets, and smartphones that have a 3.5mm output. One important caveat: because power is delivered via USB-A, devices with only USB-C ports (such as recent MacBooks or iPads) will require a separate USB-C to USB-A adapter. The speaker does not support Bluetooth or USB audio output; it relies entirely on the analog 3.5mm connection.

Best Use Cases

Budget-conscious PC users: If you are tired of tinny laptop speakers or monitor speakers, the ST702 offers a noticeable improvement for under ¥4,000. It is ideal for office work, video calls, and casual media consumption where high fidelity is not critical. Gamers on a tight budget: The RGB lighting adds a gaming vibe without breaking the bank. However, for competitive FPS games where directional audio matters, you will want a higher-end 2.1 or surround system. The ST702 is better suited for single-player or casual titles. * Secondary display or TV audio: If you have a small TV or a secondary monitor with a 3.5mm output, this speaker can serve as a quick audio solution. Just make sure the TV has a USB port for power, or use a USB wall adapter.

Things to Consider

The 4W output is modest; do not expect room-filling volume. Bass response is limited, so if you enjoy bass-heavy music or movies, consider adding a separate subwoofer (not included). The analog-only connection means you cannot use it as a USB audio device; your source must have a 3.5mm jack. The fixed 101 cm cable between the two speakers may limit placement options. If your monitor setup is wider than that, you might need to position the speakers closer together or use an extension cable. Also, the lack of Bluetooth means you cannot stream wirelessly from your phone without a cable. ## FAQ
Q: Can I use this speaker with a PS5 or Nintendo Switch? A: Yes, if the console has a 3.5mm audio output. For PS5, you can plug into the controller's headphone jack, but you will also need a USB-A port for power (the console's front USB port works). For Switch, use the headphone jack on the console or dock, and power via the dock's USB port. Sound quality will be acceptable for casual gaming. Q: Is the RGB lighting customizable? A: The lighting cycles through six preset colors automatically in response to music. There is no software control or manual color selection; it is a simple dynamic effect. If you prefer a static color or no lighting, this model may not be ideal. Q: How does it compare to speakers in the ¥5,000–¥10,000 range? A: The ST702 is noticeably less powerful and has weaker bass. Speakers in the higher price bracket typically offer better clarity, deeper low-end, and sometimes Bluetooth or USB audio. The ST702 is best viewed as a low-cost entry point; if you can stretch your budget, you will get a meaningful upgrade.
