Review: 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!

*by A***Y on 9 July 2025*

This is an amazing speaker, truly top notch in sound and build quality. It feels heavy, connects quickly as most SONY products do, there's no detail forgotten when it comes to features, yet its simplistic enough to not be overwhelming with options, and the straps to carry around the speaker are not an after thought. All around, a solid speaker that I feel is worth the price I paid (at the time $198, maybe not $350 but definitely $198) With that being said, it is NOT portable, at least for me. It gets heavy pretty quickly if you lug it around, even with the crossbody strap. If you're ok with being unable to grab the speaker and shove it into a bag or suitcase then I would opt for the smaller options for sure. If you frequent outdoor events enough to want a speaker of this physical caliber, or plan on using it as TV sound bar or static speaker system, then I would highly recommend. Over all, solid speaker, emphasis on the SOLID part of the speaker, it feels high quality and over engineered for heavy duty adventure and performance, it is just a big ass speaker that I personally wasn't ready for. I will unfortunately and begrudgingly have to return it, but if I could keep it I would.
