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.

### ⭐⭐⭐⭐⭐ Move aside Bose
*by A***. on January 26, 2026*

### ⭐⭐⭐⭐⭐ 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.
