Better Than JBL Go 3? Sanag M13S Pro Bluetooth Speaker

JBL Go 3 Pros and Cons

Jbl go 3 speaker


Waterproof and Dustproof

The waterproof rating of the GBL Go 3 is IP67, which means it is fully dustproof and waterproof, capable of being submerged in water up to one meter deep for up to 30 minutes.


Weighing only 7.4 ounces and measuring 2.7 x 3.4 x 1.6 inches (HWD), it is compact enough to fit in your pocket, highlighting the "portability" of this portable speaker.

Easy to Use

The JBL GO 3 is very simple to use. There are three prominent buttons on the fabric edge above the JBL logo for adjusting the volume and playback. Additionally, the speaker has two buttons on the opposite end of the strap for power and Bluetooth pairing—just press the pairing button.

Variety of Colors

This speaker is available in multiple colors, including "Red," "Black," "Blue," "White," "Yellow," "Green," and more. You can choose a color based on your preference.

Long battery life

JBL advertises that the GO 3 can last up to 5 hours on a single charge, but according to numerous customer reviews, its battery life far exceeds this duration. At a constant output of approximately 75dB, the JBL GO 3 can last up to 10 hours on a single charge.

Small loop

Another new feature of the JBL GO 3 is the fabric loop, which allows you to hang the speaker on a hook or clip it to a bag. The loop is permanently attached to the speaker, making it convenient if you want to hang it up and forget about it for the afternoon.

No Microphone

The GBL GO 3 does not have a microphone, so it cannot be used for making or receiving phone calls.


It only supports the SBC codec, and outdoor speakers rarely use high-quality codecs like aptX or AAC. Therefore, you might experience some audio-visual delay when watching videos paired with it.

Sinks in water

The GBL GO 3 does not float. If it falls into a pool, it will sink to the bottom, making it not the best choice for those looking for a pool speaker.

Slow Charging

The GBL GO 3 does not support fast charging. It takes approximately two and a half hours to fully charge the speaker via USB-C. This longer charging time might be inconvenient if you need a quick power boost before heading out. For those who frequently use their speaker on the go, this could be a significant drawback compared to other models that offer faster charging capabilities.

Sound Lacks Finesse

The GBL GO 3 is not known for delivering particularly refined sound. While it is loud enough to fill a fairly large room, it can suffer from sound distortion at higher volumes. This might be noticeable when playing music with complex arrangements or when the volume is turned up, impacting the overall listening experience.

No Skip Button

The GBL GO 3 lacks a skip button, meaning you cannot easily skip tracks directly from the speaker. For those who frequently skip songs or need seamless control over their music, this omission might be a pity compared to other portable speakers that include this feature.
