Sony SRS-XB33 Speaker Review

The Bose SoundLink Flex is a better speaker than the Sony SRS-XB33, though they have different strengths. The Flex is smaller, making it more portable. It has a better-balanced sound profile out of the box and has better directivity, so its soundstage sounds wider than that of the Sony. The Sony's sound profile is more customizable thanks to the graphic EQ in its companion app. It can also play stereo content without downmixing it to mono and has a longer-lasting battery life, though this can vary depending on your usage.

The JBL Xtreme 3 is a slightly better speaker for most uses than the Sony SRS-XB33. The JBL has a better-balanced sound profile and a more immersive soundstage. It can also get louder than the Sony, although there are more compression artifacts at max volume, and its battery life is outstanding. However, the Sony supports voice assistants through your smartphone. Its Bluetooth latency on Android and iOS is also much lower.

The Anker Soundcore Motion+ is a better speaker than the Sony SRS-XB33 overall. The Anker has a better-balanced sound profile, a wider-sounding soundstage, and gets louder than the Sony. It also has a longer battery life lasting over 15 hours from a single charge, though this can depend on your usage, and your experience may differ. That said, the Sony is better built, with an IP67 rating for dust and water resistance, though we don't test for this.

The Sony SRS-XB33 and the Sony ULT FIELD 1 are both portable, wireless speakers that are marketed around having enhanced bass frequencies. That said, neither has a particularly punchy or rumbly bass response. The ULT FIELD 1 does have a more balanced mid and treble response, which makes it a great choice for podcasts. Perhaps the main point of departure between the two is the difference in battery life, as the SRS-XB33 has almost double the continuous battery life, making it a solid choice for weekend camping trips. That said, there's not much to split the two beyond this. Both speakers can get similarly loud, but the ULT FIELD 1 has more compression at max volume.

The Sony SRS-XE300 and the Sony SRS-XB33 are similar speakers, though the XE300 is slightly better overall. The XE300 can get a bit louder, though it has a touch more compression at max volume, so audio quality doesn't sound as clean at louder volume levels, but not by much. It also has a longer-lasting battery life of almost 17 hours. While they both support voice assistants through your smartphone, the XE300 performs better at registering your commands. It can also produce slightly deeper bass. That said, the differences between the XB33 and the XE300 are not all that pronounced, so if you already own the XB33, it isn't worth the upgrade.

The Sony SRS-XE200 is a slightly better speaker than the Sony SRS-XB33. Overall, the speakers perform fairly similarly at a similar price point, only the XE200 is smaller, making it more portable. It has a slightly longer-lasting battery life too. Also, while both speakers support voice assistants through your smartphone, the XE200 is significantly better at registering your commands from far away and in noisier environments. That said, while the XB33 gets a touch less loud than the XE200, it has less compression present at max volume, so audio quality doesn't degrade as much as you increase the volume.

The Sony SRS-XB23 and the Sony SRS-XB33 are similarly performing speakers. The SRS-XB23 is smaller and has a 360-degree design, so its soundstage is perceived as wide.
