Review: Ahmm okey - Not so great and also not so bad , when you are shifting from the JBL sound signature style , which would takes some time to adapt to this Sony's signature. Ult2 mode is the best in this , and if you want to invest this much money for a Bluetooth speaker then Harmon kardon would be better 👍

### ⭐⭐⭐⭐⭐ Superb high end Bluetooth Speaker!
*by D***. on 11 July 2025*

Excellent!! I am an audiophile! Having said that, I pay attention to all things sound quality related. If you are like me, MP3 files etc don’t cut it. This model was made for the demanding listener. Not all Bluetooth codecs are the same My FiiO M11+ portable player has Ldac and a 3.5 Line output. Both of these feature are able to be utilized on the Sony ult field 5. I play dsd and ripped cd files from my FiiO to the Sony. The sound of the Sony is often described as bass heavy. Nonsense. This speaker on the ult2 setting is rich full and natural. The speaker walks the fine line between just enough bass to sound natural,(bigger drivers) and reasonable Portability. The amplifier has decent power output to get to enthusiastic loudness, but still sounds very natural at modest levels as well, and a substantial sized lithium battery to have long all day listening sessions. Like other reviews have pointed out, the colour changing lights are a surprise. They are not too flashy, or over done. They add to the experience. The carry strap is very well made with the ends being metal and not plastic. The sound quality is very well tuned and musical. It is not boomy overblown bass. If you play lesser quality low bitrate files on a lesser Quality Bluetooth codecs, then perhaps you will have a different sound. But careful examination of this models features and build quality and its weight,(7lbs) will tell you the type of audio quality to expect at high bitrate playback over Ldac Bluetooth or direct line input, which is necessary for excellent sound quality. This is a portable Bluetooth speaker for the discerning listener. Well done Sony!
