This is my second review of the Redragon model GS813 desktop bluetooth speakers C explanation below.
PROS:
easy to connect bluetooth took less than 3 minutes
volume control knob (not many bluetooth speakers have this)
Sound varies from mellow to BLAST! with no scratchiness
attractive black wood cabinets
adjustable bass and treble knobs
USB and mini-SD (TF) slots
VCA cable for AUX mode
The volume control knob is important to me because I sometimes watch videos where the sound varies greatly. If I want to lower the sound on a portion of the video, I just reach over and turn the volume down.
NOTE: When I first connected the speakers to my laptop, I encountered a screeching noise whenever a video stopped or a song ended. The noise occurred every 15 seconds until I restarted the video or played another song. I blamed the speakers, but the problem was not the speakers. It was the bluetooth connection coming from the laptop. If this problem happens to you, simply delete the GS813 connection, then reconnect GS813 to the bluetooth. Problem Solved with this easy fix.

Got these speakers to replace my disappointing soundbar, which kept losing its Bluetooth connection and did not have any bass to speak of. These speakers have several options for hooking up to your sound source wireless Bluetooth, or wired through the RCA inputs for AUX mode, or using a USB flash drive or SD card as your source but I got this mainly for the Bluetooth option. You first must plug the 2nd speaker's built-in cord into the primary speaker. The cord length is about 32 inches long, so this is the maximum distance they can be from each other, which is more than enough for a desktop. All the controls are on the 1st speaker on/off, volume knobs, mode selection button, play buttons and the ports for a SD card & USB thumb drive. These are all very easy to use. I was able to connect using the Bluetooth mode very quickly, and it stays on & connected so I don't have to fuss with it.

As far as sound quality this is very subjective, but I am really pleased with it. This has much more bass than the soundbar, although if you like really heavy bass it might not work for you. Overall it has a fuller sound and can be turned up much louder than my soundbar. This suits my needs and my budget.

Redragon GS813 Wireless Desktop Speakers, 2.0 Channel Bookshelf Speaker

FIRST IMPRESSIONS: Yes, I know the seller has dimensions on their page but I was still surprised how big these were.

The case looks great with a deep wood grain effect.

I do like to try and use things without looking at the instructions just to see if the item is designed to be intuitive in use. Within two minutes of opening the box, I had these speakers plugged into a power outlet, connected together, paired to my Samsung tablet and playing music on you tube.

Once we had finished listening to YouTube, I immediately paired it to our TV with ease and listened to the world cup.

They have good volume and a nice loud base.

USE: We won't be using these for the computer but will use in the living room area as an old school music system. When we want to listen to music we will just connect our tablets to our speakers.

CONCLUSION: These speakers look good, they are easy and intuitive to use. The sound quality is good, although not great. I am not an audiophile so I am not sure how to accurately define it. It's not tinny, it's just not crisp. I am rating this 5 stars despite the sound quality because I think that to get better sound quality it would be found at a different price point.

REVIEW PHILOSOPHY: I only review a product if it is something I am capable of critically evaluating through comparison, testing and use. This means I have experience of using similar items; or that I have equipment or tools that I can test it with; or that I have an upcoming need so I can actually use. I am as selective about getting an item to review as I would be about purchasing that same item, so yes, I expect it to be a good product. My reviews are NOT based on packaging or if it was delivered timely.
