These passive radiators move along with the vibrations of the woofer that produces the bass. This makes the bass even stronger and you can enjoy a clear beat. The ULT button on the speaker provides an even deeper bass and fuller sound, so you can completely immerse yourself in your music. The speaker has an IP67 certification, so it's dustproof and water-resistant, so you can take it with you to the beach or pool without issues. The speaker is shockproof, so it can take a hit.

Our expert review

Compact speaker with excellent sound.

  • Clear bass tones
  • Easy to take with you
  • Compact size
  • Less full sound without ULT Bass
The Sony ULT Field 1 is a compact speaker that has a solid bass. I personalize the sound in the app, so I can enjoy music my way. The sound is a bit flat when the volume is turned down and the ULT Bass mode is not turned on. ULT Bass mode There is a ULT button on the speaker that I use to turn on the ULT Bass. In this mode, the speaker amplifies the bass and produces more powerful sound. I hear the difference clearly, because the bass really comes through in this mode. In addition, I also hear more detail in the music with this mode on. I think it's a shame that the music briefly interrupts with a sound effect when I press the button. Great sound The sound is fine. If I don't have the ULT Bass mode on, the sound sounds a bit flat. This means I hear fewer details. With the ULT Bass mode on, the sound sounds fuller and more powerful. This is partly due to the harder bass tones, because they produce strong sounds. That's why I prefer to listen to music with this mode on. If I want to hear the music clearly from the other side of my room, I turn up the volume. Otherwise the music will not come into its own. Sony Music Center App In the app I adjust the sound with the equalizer. This is how I control the low, middle and high tones. I like to hear the vocals in the music clearly, so I turn up the mids and highs a bit. Compact design The carrying cord makes it easy to take the speaker with me. In addition, it is compact, which makes it easy for me to put it in a bag. I have fairly small hands, but it fits comfortably in my hand. The logo is reflective, so you see rainbow colors in the logo. I think this is a nice detail.

Good speaker to take with you/in rooms

  • Portable
  • Sound quality
  • No carrying case included as standard
I have used this speaker in recent weeks both indoors (living room) and outdoors (going to the water with friends) and am very pleased with it! The sound is top-notch in all circumstances (as you would expect from Sony) and with the ULT button you can switch on specific settings so that certain music sounds even better! Connecting is also very easy and the carrying cord makes it easy to hang it on something or carry it in your hand. In the latter case, the box does not feel heavy, so that is great. Furthermore, you can play music for quite a long time on a full battery! If Sony would have given this speaker lighting effects and included a (soft) carrying case as standard, this would have been perfect.

Solid bass for a reasonable price.

  • Good bass
  • Easy to take with you
  • Easy to operate
  • The bass is only good when the ULT mode is on
After testing this Sony ULT Field 1 for two weeks, I am really impressed with the ULT feature. The ULT button activates a powerful bass that is especially useful at parties or large groups, while the speaker can also be soft and subtle when necessary. With a handy adjustable string and a weight comparable to that of a water bottle, the speaker is ideal to take anywhere. Plus, it's waterproof, which makes it great for taking outdoors. With the Music Center app, you can easily pair the speaker and adjust the sound setting, the app looks a little dated but overall the Sony ULT Field 1 offers excellent value for the price.
