AI Verdict
This $20 USB-powered soundbar instantly upgrades terrible laptop audio for budget-conscious remote workers, but bass lovers should look elsewhere.
This soundbar strictly serves basic desktop audio upgrades. The 10W output and single-cable USB connection handle Zoom calls and YouTube videos perfectly. The lack of low-end frequencies from the small drivers ruins the experience for serious music listening or gaming.
If you want actual bass, look for a 2.1 computer speaker system with a dedicated subwoofer and at least 30W of peak power.

Chance this product isn't for you
Pros
- 16-inch width fits perfectly under most 24-inch or 27-inch desktop monitors
- Runs entirely off a single USB port for both power and audio
- Includes a tethered USB-C to USB-A adapter so you won't lose it
- Fabric front grille looks much more premium than typical budget plastic speakers
- Bluetooth 5.3 mode lets you stream from your phone while working
Cons
- Dual 5W drivers produce almost zero sub-bass for music or gaming
- LED light strip is hidden underneath and nearly invisible during daylight
- No 3.5mm aux input or headphone passthrough jack
- Must remain plugged into USB power even when using Bluetooth mode
Dimension Scores
Clear vocals for podcasts and calls, but the 10W peak output sounds hollow for music.
Dual 5W drivers and passive radiators fail to produce meaningful low-end punch.
USB plug-and-play and Bluetooth 5.3 provide convenience, but the missing 3.5mm aux port limits older devices.
The fabric mesh looks great and the 16-inch footprint saves desk space, though it requires constant tethered power.
Best For
- Clutter-free home office setups needing a single-cable audio solution
- Upgrading tinny laptop speakers on a strict sub-$30 budget
- Sliding under low-clearance monitors where traditional bookshelf speakers won't fit
Not Recommended For
- Bass-heavy music listening or immersive PC gaming
- Portable use away from a laptop or wall charger
- Connecting to monitors that only have a 3.5mm audio out port
Watch Out For
- No internal battery — you must keep it plugged into a USB port or 5V wall adapter to use the Bluetooth feature.
- Bottom-mounted LEDs — the light strip faces the desk, hiding the RGB effects unless the room is pitch black.
- Tied volume limits — the speaker's maximum volume bottlenecks at your device's USB power output, resulting in quiet audio on older laptops.
- No 3.5mm jack — you cannot connect this speaker if your monitor or PC only outputs audio via an aux cable.

What Buyers Say
Desk space savings drive most of the positive feedback, as the 16-inch frame slides right under low-clearance monitors. The single-cable USB setup eliminates cable clutter entirely. The RGB lighting draws heavy criticism because the LED strip mounts on the bottom edge, making it invisible unless the room is pitch black. Audio-wise, reviewers note a massive step up from laptop speakers for dialogue, but the 5W drivers completely fall flat for bass-heavy music.
“For 20 bucks it totally beats my crappy laptop speakers, but don't expect to throw a party with it and the RGB light is basically just glowing at my desk mat.”
Common Praise
- Single USB cable handles both power and audio seamlessly
- Fabric front grille hides cheap plastic construction
- 16-inch length fits perfectly between monitor stand legs
- Voices in YouTube videos and Zoom calls sound crisp and clear
Common Complaints
- Bottom-facing LED strip is impossible to see during the day
- Zero bass response for hip-hop or action movies
- Voice prompts when switching modes play at a loud volume
- No 3.5mm aux input for older devices
Ownership Tips
- The USB-C adapter stays tethered to the cable so you won't lose it when switching between devices.
- Volume controls sync directly with Windows, eliminating the need to manage two separate volume levels.
- Dust collects quickly on the fabric mesh and requires a vacuum brush to clean.
Frequently Asked Questions
Does this have a built-in battery for portable use?
No. It must remain plugged into a USB power source like your PC, laptop, or a wall adapter at all times, even in Bluetooth mode.
Can I connect this to my monitor's headphone jack?
No. The base R100 model only accepts audio via USB or Bluetooth. It lacks a 3.5mm aux input.
How do I switch between USB and Bluetooth mode?
Click the 'M' button on the top of the speaker. A voice prompt confirms which mode is active.
Will the RGB lights sync with my PC's software like iCUE or Razer Synapse?
No. The lighting operates entirely via the physical button on top of the speaker, cycling through 4 pre-set modes.
Does it have a microphone for Zoom calls?
No. You still need your laptop's mic or a dedicated headset for voice input.
How long is the attached USB cable?
The built-in USB cable measures approximately 4 feet long. You might need a USB extension cable if your PC tower sits far from your monitor.
Buying Guide
Budget PC soundbars trade audiophile sound for space-saving convenience. USB-powered speakers max out at around 10 watts, giving you plenty of volume from two feet away without filling the whole room. Check your computer's I/O before buying—this specific model requires a free USB-A or USB-C port and lacks a standard 3.5mm headphone jack.
10 Watts Output Power
This measures the total electrical power the speakers handle. 10W provides enough volume for personal desk use, similar to a loud portable Bluetooth speaker, but won't rattle your windows.
USB Plug & Play
The speaker has a built-in sound card. It bypasses your computer's internal audio processing and pulls both power and digital audio through one single cable.
Bluetooth 5.3
The latest Bluetooth standard offers lower latency and better stability, ensuring the audio won't lag behind the video when watching YouTube on your phone.
Alternatives
If you need deep bass, search for a '2.1 computer speaker system' with a dedicated subwoofer. If you need to connect to a monitor without USB ports, look for a soundbar with a '3.5mm aux input'.
