AI Verdict
The SOULION R100 is a $30 USB-powered soundbar that gives dual-monitor home office setups a massive upgrade over tinny laptop speakers without cluttering the desk.
This soundbar is strictly for desktop users who want to bypass 3.5mm cables and power bricks in favor of a single USB connection. The 10W output and dual 5W drivers are a massive step up from built-in monitor speakers, but the lack of a dedicated subwoofer means it falls flat for heavy gaming or action movies.
If you need deep bass for gaming, look for a 2.1 system with a dedicated subwoofer and at least 30W of total output.

Chance this product isn't for you
Pros
- 16-inch width fits perfectly under most 24-inch or 27-inch monitors without blocking the screen
- True plug-and-play USB audio means you don't have to deal with a separate 3.5mm cable or power brick
- Fabric front grille and 2.5-inch cube profile look significantly more premium than bare plastic
- Top-mounted tactile buttons make it easy to switch between USB and Bluetooth modes without opening PC settings
- Includes a USB-C to USB-A adapter in the box for modern laptops
Cons
- Bottom-firing LED strip is nearly invisible during the day unless you're sitting in a dark room
- Two 5W drivers lack a subwoofer, meaning bass response drops off a cliff below 150Hz
- No built-in microphone, so you still need a headset or standalone mic for Zoom calls
- Lacks a 3.5mm aux input, restricting wired connections entirely to USB
Dimension Scores
The dual 5W drivers deliver clear vocals for podcasts and YouTube, but music sounds thin compared to larger bookshelf speakers.
With no dedicated subwoofer and a 150Hz frequency floor, bass is virtually non-existent, though it gets loud enough for a small office.
True single-cable USB audio and Bluetooth 5.3 are great for the price, but the lack of a 3.5mm jack restricts older devices.
The fabric grille looks nice and the 16-inch footprint is desk-friendly, but it requires constant USB power to function.
Best For
- Work-from-home setups needing clear vocal audio for YouTube and podcasts
- Tight dorm room desks where a multi-speaker setup won't fit
- Users who want to seamlessly switch between PC audio via USB and phone audio via Bluetooth
Not Recommended For
- Bass-heavy music listening or immersive PC gaming
- Living room TV setups requiring HDMI ARC or a remote control
Watch Out For
- The RGB lighting is located on the very bottom edge facing the desk, making it almost impossible to see in a well-lit room.
- Volume controls sync directly with your source device, so if your phone or older tablet has low max volume output, the speaker won't get very loud.
- There is no internal battery in the standard R100 model—it must remain plugged into a USB port or power bank to function, even in Bluetooth mode.
- No 3.5mm headphone jack on the unit, so you can't easily plug in wired headphones for late-night listening.

What Buyers Say
The most consistent surprise from buyers is that the R100 acts as its own USB audio interface, meaning you don't need to plug in a separate 3.5mm audio cable to get sound from your PC. Users love the 16-inch form factor because it slides perfectly under 24-inch and 27-inch monitors without interfering with the stand. A major recurring complaint is the placement of the RGB LED strip. Because it fires directly downward into the desk, buyers note the lighting is practically invisible during the daytime. Audio-wise, owners agree it destroys standard laptop or monitor speakers for vocal clarity, but they universally warn against buying it if you care about bass.
“For 30 bucks it completely fixed my crappy monitor audio for youtube and zoom, just don't expect it to shake your desk with bass and you'll be happy.”
Common Praise
- Single-cable USB connection handles both power and audio seamlessly
- 16-inch length fits perfectly between monitor stand legs
- Fabric front grille looks much more expensive than bare plastic
- Top-mounted tactile buttons are easy to reach without looking
Common Complaints
- Bottom-firing RGB lights are too dim to see in a sunlit room
- Zero sub-bass response for music or action games
- No 3.5mm aux input for older devices
- Volume buttons adjust the host device's master volume, which can be finicky on some Android tablets
Ownership Tips
- The speaker remembers your last used mode (USB or Bluetooth) when you power your PC back on
- If your PC's USB ports stay powered when asleep, the speaker's RGB lights might stay on until you manually turn them off
- The included USB-C adapter is small and easy to lose if you don't leave it permanently attached to the cable
Frequently Asked Questions
Does this have a built-in microphone for Zoom calls?
No, it does not have a microphone. You will need to use your laptop's built-in mic or a separate headset for calls.
Can I use this with my TV?
It is not recommended. It lacks HDMI ARC, optical inputs, and a remote control, and relies entirely on USB for wired audio.
Does it have a battery for portable use?
No, the standard R100 does not have a battery. It must be plugged into a USB port or a USB power bank at all times, even when using Bluetooth.
How do you turn off the RGB lights?
You can cycle through the four lighting modes or turn the LEDs completely off by pressing the sun icon button on the top of the speaker.
Will this connect to a Mac with only USB-C ports?
Yes, SOULION includes a USB-C to USB-A adapter in the box specifically for newer MacBooks and thin-and-light laptops.
Does it have a 3.5mm aux input?
No, the base R100 model only accepts wired audio via USB. If you need 3.5mm, you have to upgrade to the R100 Plus model.
Buying Guide
When buying a budget PC soundbar, you are paying for desk space and convenience, not audiophile sound. The SOULION R100 is designed to fix the terrible, tinny audio that comes out of standard monitors and laptops, giving you clear voices for YouTube and meetings. Because it relies entirely on a 5V USB port for power, it physically cannot draw enough wattage to produce deep, thumping bass. You need to decide if a clean, single-cable setup is more important to you than a rich music listening experience.
10W Peak Power (Dual 5W Drivers)
This tells you how loud the speaker can get. 10 watts is about twice as loud as a standard laptop, perfect for sitting three feet away, but it won't fill a living room.
USB Audio Interface
Instead of using your computer's built-in headphone jack, the speaker processes the digital audio itself through the USB cable, which often eliminates the static or buzzing sounds common in cheap PC audio ports.
Bluetooth 5.3
The latest Bluetooth standard means less audio delay when watching videos on your phone, and it connects much faster when you switch modes.
Alternatives
If you need thumping bass for gaming, search for a '2.1 computer speaker system' which includes a separate subwoofer box that sits on your floor. If you want to use this with a TV, look for a soundbar with 'HDMI ARC' or 'Optical input' and an included remote control.
