Review: Better then the JBL Flip 7! - The Sony ULT Field 1 is perfect for the price you are paying for, it's a good speaker in terms of Sound, bass and size, it's a good sized speaker, the carrying strap built in the speaker is perfect for carrying, Bluetooth connectivity is good, the battery is good enough for most people, and the stereo pair feature in this speaker makes it sound even better! I did do a comparison with the JBL Flip 7, and the Sony ULT Field 1 is better in sound quality and it's cheaper. So if you want a good speaker for a good price, get the Sony ULT Field 1.
Review: Move aside Bose - I had a Bose SoundLink Micro Bluetooth Speaker in my shower to enjoy music while showering. It was good, nice size and average sound. I gave this Sony ULT Fiel 1 a try and man does this thing puts Bose on the bench. Amazing sound, both on bass and treble, its volumen strength is scary, I cannot use this at half a volume on Spotify because is way to much loud. Nice design too, its battery life is great, worth its price every penny. Fully compatible with my iPhone 16 Pro.

### ⭐⭐⭐⭐⭐ The Sony ULT Field 3: The Sweet Spot
*by D***E on December 11, 2025*

This is an amazing speaker. Although it is very portable, it does verge on being too big to carry around with you everywhere. I'm no audiophile, but this speaker sounds great to me. It carries a proper punch and the highs are nice and crisp. There is a noticeable difference in sound with the ULT mode off or on. You're going to want to keep it on if you want that rumbling bass sound, but there's enough boom with it off. I haven't dropped it and don't plan on doing so, but the rubber molding on each end feels sturdy and able to absorb a decent fall. The waterproof feature is nice in case you ever leave this speaker out in the rain by mistake or want to keep it near a pool. Battery life is great. I have not timed it, but the battery last for serval days with multiple hours of use per day. I'm confident the battery claims from Sony are accurate. The ULT Field 3 is the sweet spot if you want a speaker that can be your primary Bluetooth speaker as well as a portable option. Get it. Your neighbors might hate you, but your ears will love you.
