Good sound if placed right and you tweak it

First things, audio performance is always going to be subjective but as shipped I found the Bass overbearing and speech thin and reedy. However connect it to the app and the eq adjustments let you get it sounding great particularly if you place it on a solid surface or close against a wall or similar. The lights are fun but a bit of a gimmick. IP68 waterproofing is a good feature as this is most likely to be used out on the patio and very likely to be left out in the rain in an English summer. Slightly disappointed with the power bank function as half charging my Pixel fold wiped out 50% of the reported charge in the speaker but all in all I am glad I have got it.

Excellent sound quality, loud and deep

I actually highly rate this speaker. It was a lot better than I expected.First thing I noticed was the sound, it’s loud for the size and the bass has a nice punch to it without sounding 'muddily'. I’ve used it around the house and even in the garden and it fills the space well. Doesn’t feel like one of those tiny that even sound tiny.What I liked is how easy it is to just grab and go. The size is perfect, you can literally chuck it in a bag or carry it around without thinking. I mean, it fits in my pockets.Battery life has been solid too, I haven’t had to constantly charge it. The waterproof side is a great addition, so if you want to use in the bath, you can do without worry.Overall, this is an excellent speaker and it does the job properly. I liked it for everyday use, quick music in the house, and taking it out without worrying. Good value for money for the price as the sound is excellent.

Small but mighty - a great everyday speaker

I’ve been testing this speaker over the past few days and I’m genuinely impressed, especially given how compact it is.Setup was really straightforward - it showed up straight away in my Bluetooth list and connected without any hassle. The QR code in the booklet didn’t work for me, but I just searched for the app in the App Store and found it easily, so not a big issue.First impressions were really positive. It has a nice bit of weight to it - not heavy to carry around, but enough that it feels solid and well made rather than cheap or hollow. The packaging is also worth mentioning as it seems quite eco-conscious, with minimal excess and even soy-based printing, which is a nice touch.Sound-wise, it’s surprisingly good for the size. It’s clear with a decent bit of bass (not anything extreme, but definitely there), and it gets louder than I expected. It easily fills my kitchen and the sound carries into the next room, so I’d imagine it would hold up well in a garden too. You can tweak the bass in the settings as well, which does make a noticeable difference.It’s really portable too - lightweight, easy to move around, and the strap makes it handy for hanging up somewhere (like a greenhouse or shed) or taking outside. It feels ideal if you like having music on while moving between rooms or doing things around the house.The controls are simple and easy to use - the buttons are well spaced, nicely tactile, and not overcomplicated. I also really like the LED battery display, as it gives a clear idea of how much charge is left rather than the usual vague indicator lights.Charging is via USB-C, which is straightforward, although you’ll need the right plug if you don’t already have one. That’s more of a general tech thing than an issue with this speaker, but worth keeping in mind.There are a couple of extra features too, like an SOS alarm and an eco mode that turns off lighting features, which is a nice bonus.Overall, it’s a really solid little speaker with impressive volume for its size. It’s especially good if you want something portable for around the house or garden. I’d happily recommend it.
