Our Verdict

Sony SRS-XB33

Sony ULT FIELD 1

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.
