    It’s a great speaker
    I bought this speaker to replace an old Sony Bluetooth speaker that I loved. The sound on this one is amazing and even though it is bassy, it’s not so bassy that it overpowers everything else. I like it and would recommend it.

    Great sound
    This was a birthday present from my wife..she’s very particular in choosing and paying for substantial items.. she’s listened to most other brands before deciding on the Sony.. I’m glad she did..

    Not great.
    Not great. With most Bluetooth speakers, the minute I turn them on, they connect with whatever device they are used to connecting with. Not the ULT Field 5. I have to go to my Bluetooth connections, try to connect, it doesn't work, I have to turn off Bluetooth, turn it back on, etc. Each time, I have to fiddle to connect the speaker. It's also not loud enough for my purposes even though it should be according to its dB info.
