AI Verdict
This is a cheap, lighted soundbar for a basic desktop audio upgrade from tinny monitor speakers, but it's definitely not for audiophiles or bass lovers.
This is a strong fit if your main goals are getting something cheap that's better than your monitor's speakers and looks cool. The dual Bluetooth/3.5mm connectivity and USB power are convenient for a clean desk. However, the widely reported lack of bass and potential for static noise make it a weak fit for anyone who cares about sound quality for music or immersive movies.
If you need better audio with actual bass, look for a 2.1 speaker system that includes a dedicated subwoofer.

Chance this product isn't for you
Pros
- Offers both Bluetooth and 3.5mm wired connectivity options.
- USB-powered, so it doesn't require a separate wall outlet.
- Four dynamic LED lighting modes with a dedicated button to turn them off.
- Compact, slanted design fits neatly under a monitor and directs sound upward.
- Physical volume knob provides more tactile control than buttons.
Cons
- Bass is consistently reported as weak or non-existent.
- The USB power and 3.5mm audio cables are permanently attached and can be too short for some setups.
- Some users report a persistent low-level static hum or hiss.
- Audio quality can distort at maximum volume.
- Bluetooth connection can introduce noticeable audio lag, making it unsuitable for competitive gaming.
Dimension Scores
The sound is often described as flat and mid-heavy, a step up from laptop speakers but lacking richness for music.
Bass is consistently reported as extremely weak or absent, and while volume is adequate for a desktop, it won't fill a room.
Having both Bluetooth and a 3.5mm wired option is a very flexible and strong feature for a budget speaker.
It's lightweight and compact, but the all-plastic construction and non-detachable cables feel cheap.
Best For
- Upgrading from terrible built-in laptop or monitor speakers on a tight budget.
- Adding colorful RGB lighting to a desk setup for visual flair.
- A simple audio solution for a kid's computer or a secondary workstation.
- Listening to podcasts or YouTube videos where deep bass isn't critical.
Not Recommended For
- Anyone who prioritizes music quality and deep bass.
- Users who are sensitive to audio latency for gaming or video editing.
- Setups that require long cables for placement flexibility.
Watch Out For
- The LED lights do not remember their last setting and reset to the default mode every time the speaker is powered on.
- A noticeable static or buzzing noise is a common complaint, which can be very distracting at low volumes.
- The hardwired USB and 3.5mm cables are not detachable, limiting placement and making them a point of failure.
- The advertised 'Surround Sound' is a digital effect, not a true multi-channel audio experience.
- Bluetooth connectivity can be unreliable, with some users reporting connection drops.

What Buyers Say
The most common reaction to the SOULION R50 is that it's surprisingly loud for its price, but the total lack of bass is a huge letdown for anyone wanting to listen to music. The RGB lights are a big draw, with several modes and the crucial ability to be turned off completely, though it's annoying that they reset every time you power on. Setup is plug-and-play, but the short, permanently attached cables are a major frustration for cable management. A significant number of users complain about a persistent low-level static hum, which for some is an immediate deal-breaker. While it offers both wired and Bluetooth connections, the Bluetooth mode can suffer from audio lag.
“it's fine for 25 bucks i guess, its louder than my monitor but there's ZERO bass and this weird buzzing sound is driving me crazy. should have just saved up for something better.”
Common Praise
- The RGB lighting is vibrant and has a 'rhythm mode' that reacts to music.
- It's very easy to set up; just plug in the USB and 3.5mm cables.
- The slanted design fits perfectly under a monitor and saves a lot of desk space.
- Sound is clearer and louder than most built-in monitor or laptop speakers.
- The physical volume knob is convenient and easy to use.
Common Complaints
- There is virtually no bass response, making music sound flat.
- A constant, low-volume static or buzzing noise is present for many users.
- The hardwired cables are too short for larger desks or if the PC is on the floor.
- Audio quality gets distorted and harsh when you turn the volume all the way up.
- The light settings aren't saved, so you have to reset your preferred mode every time you turn it on.
Ownership Tips
- You'll quickly get annoyed by having to cycle through the light settings every single morning if you don't like the default rainbow mode.
- The fabric mesh on the front is a dust magnet and is difficult to clean without just pushing the dust around.
- For any kind of gaming, you'll learn to always use the 3.5mm cable to avoid the frustrating audio lag from Bluetooth.
- The single volume knob controls your computer's system volume directly, which is convenient but can feel less precise than dedicated up/down buttons.
Frequently Asked Questions
Can you turn the LED lights completely off?
Yes, there is a dedicated button on the speaker that cycles through the light modes and can turn them off entirely.
Does it need to be plugged into a wall outlet?
No, it's powered by a standard USB-A port on your computer, monitor, or a separate USB charger.
How do you switch between Bluetooth and the 3.5mm cable?
There is a mode button, labeled 'M', on the side that you press to toggle between Bluetooth and 'Aux' (wired) mode.
Is there an audio delay when using Bluetooth?
Some users report a noticeable delay over Bluetooth, which can cause sync issues with videos and games. Using the 3.5mm cable is recommended for gaming.
Are the cables detachable?
No, the USB power cable and the 3.5mm audio cable are permanently attached to the soundbar.
How loud does it get?
It gets loud enough for personal listening at a desk, but it's not designed to fill a room with sound. Some users note the audio quality degrades at max volume.
Buying Guide
When you're buying a soundbar this cheap, you're paying for an aesthetic and a simple audio boost, not a high-fidelity experience. The main things you need to worry about are how it gets power—USB is convenient but can sometimes introduce electrical noise or hum. Check user reviews for complaints about static. Also, make sure the cables are long enough for your desk setup, as many cheap speakers have short, non-detachable cords.
speaker_type: Soundbar
This just means it's one long speaker instead of two separate ones. It's designed to sit under your monitor to keep your desk looking clean and save space.
power_source: Corded Electric (USB)
It gets power from a USB port, not a bulky wall adapter. This is great for a minimalist setup, but you need a free USB port on your computer or a hub.
connectivity: Bluetooth, 3.5mm
You get two ways to connect. The 3.5mm plug is your standard headphone jack—it's reliable and has no lag. Bluetooth lets you connect wirelessly, which is great for playing music from your phone, but it can have a slight delay that's noticeable in games.
Alternatives
If this isn't enough and you want much better sound with real bass, stop looking at single soundbars. Instead, search for a '2.1 computer speaker system' which will give you two satellite speakers and a separate box called a subwoofer that's dedicated to low-end frequencies.
