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.

The Sony ULT Field 1 speaker is definitely recommended for anyone looking for a compact, portable speaker with excellent sound quality. The price-quality ratio of this speaker is truly perfect. Despite its small size, the ULT Field 1 speaker delivers a powerful and clear sound, so you can always enjoy your favorite music, wherever you are.

A big plus of this speaker is the easy connection with your smartphone or tablet. Connecting is effortless and within seconds you can stream all your music through the speaker. In addition, the battery life of the ULT Field 1 speaker is also impressive. With a fully charged battery, you can enjoy your favorite music for hours without having to worry about charging.

All in all, the Sony ULT Field 1 speaker that I tested is a great choice for anyone looking for a high-quality, compact speaker with an excellent price-quality ratio. Together with the app that SONY has developed, you can adjust the sound completely to your liking. I am very satisfied with my purchase and can highly recommend this speaker.

Great for basic pop music

Handy
Good volume
Good range
Without ult tinny

I use it as a kitchen box. Music while cooking and washing dishes. It's fine for music with vocals. Complex instrumental music: not good enough. Anyone who likes bass should turn on ULT.
