Great little speaker
We wanted a speaker that we could listen to podcasts /shower and I previously purchased a cheap version that just sounded tinny . I spent a bit more money and this is absolutely worth the price. It sounds great nd is really portable . You’ll not regret this purchase.

Battery life
That battery life is not 14 hours lucky if it’s lasts 6, Had the third generation and the battery life was much better

Great sound
Very pleased with the sound, reviewed better than the rectangular models. Slightly baffled as to why this model cannot be used with the app. I would have thought paying £89.99 would qualify for app use.

Fantastic
I’ve been stealing my sons speaker for years, as do the mechanics in his workshop, when my portable speaker died I asked him what he had so I could buy it and he sent me the link for this with the caveat that this is the updated version and it’s quite expensive. Well he’s had his for 4 years so far, he takes zero care, it’s flung around wherever and it’s still loud enough to use as a radio in a workshop with no distortion. So I bought it. It’s perfect, and if it only lasts 4 years then it’s still cheaper than buying the £20 ones once a year and it performs better.
