Review: Faultless Sony - Great product from Sony. If you're looking for a very affordable, good looking speaker - this is the one. The ease of setup is great, just a simple NFC connection with your phone and you're good to go. It has a basic range of functionality, but it's more than enough. The ULT button adds a richer and deeper bass to the music, the speaker sound easily fills a room the size of a classroom for example. Overall a top Sony product.
Review: Good quality portable speaker - Got a good base kick.. looks good and is exactly what I wanted... Loud but not oppressively so for my ears.. Might not be loud enough for some if you want it banging... But for me was well worth the money.. Good clarity and with the bass boost off you can really hear the treble .. I haven't yet tested the durability but it is rated high and the rubber is thick over the ports .. So I imagine it will be quite durable.

### ⭐⭐⭐⭐⭐ Great bit of kit
*by F***A on 3 June 2025*

I wanted something that was simple but robust enough to take a few knocks when I’m working in the garage and this came out top in my research. It’s fair to say that I’m not disappointed. The speaker is waterproof, dustproof, and rustproof with an IP67 rating, which is ideal for the garage environment. It can be used vertically or horizontally, so it has a small footprint, and doesn’t take up much room in the workspace, but I can also hang it by the carrying handle. It paired with my phone, my partner’s phone, and a tablet with no issues at all. To me, the sound is brilliant. I was warned that the bass might not be great, but it has handled all of my special ‘test the speaker out’ tunes and although there could be more bass, what’s is there is more than adequate for the average person, especially if you use the ULT button. I do have the option to add an additional linked speaker in the future if I want to. The battery life is good, too, and I can get at least 2 or 3 evenings out of it before it needs to be charged. All-in-all, a great bit of kit that’s worth the money. Recommended.
