The Sony SRS-XB23 is a portable cylindrical speaker. Thanks to its 360-degree design, its soundstage is perceived as wide and spacious. While its sound profile lacks low-bass out-of-the-box, it also has a graphic EQ via its companion app, which is nice if you like to tweak its sound profile. Unfortunately, it doesn't get very loud, and there are compression artifacts at max volume. That said, it's durable and well-built, making it a suitable option if you're looking for a speaker that you can take with you outdoors.
Our Verdict
The Sony SRS-XB23 isn't bad for music. Its sound profile has a touch of extra boom in the bass range, and it can sound a bit veiled due to its recessed treble. That said, vocals and lead instruments are still reproduced pretty clearly and accurately. Also, you can customize its sound using the graphic EQ in the Sony Music Center app. However, even with its Extra Bass feature turned on, it still struggles to reproduce the deep rumble in the low-bass, so it's not ideal for bass-heavy genres like EDM.

The Sony XB23 is middling for videos and movies. It has fairly low latency with both Android and iOS devices, so you shouldn't notice a delay between the audio you hear and the video you see. Some apps can compensate for latency differently, though, so your real-world experience may vary. This speaker doesn't get very loud, unfortunately, and it can't reproduce the deep rumble found in action-heavy scenes.

The Sony SRS-XB23 is compatible with the voice assistants on your paired smartphone. Per our testing methodology, we use a series of recorded voice commands to test a speaker's voice assistant performance to ensure consistency across our reviews. However, like other Sony Extra Bass speakers we've tested, the Sony XB23 didn't respond to these recorded commands. It did register commands given in a normal speaking voice, but this isn't part of our testing process.

The Sony XB23 is satisfactory for outdoor use. It has a very lightweight, portable design, so you can easily bring it with you on the go. There's even an adjustable strap to help you attach it to your bag or backpack. It has an IP67 rating for dust and water resistance that certifies it to be fully dust-tight and immersible in up to a meter of water for 30 minutes. Unfortunately, it can't get very loud, so it can't fill up a large space with your audio.

Thanks to its balanced mid-range, vocals, and lead instruments still reproduce pretty clearly. There's also a graphic EQ available in the Sony Music Center app so you can customize its sound.
