Yes, the Wonderboom is bigger than the Minirig Mini - it's about twice the size, in fact - but it is still very small in its own right and is certainly very portable. In short, we think that someone eyeing-up the Minirig Mini could and should also consider the Wonderboom, and the latter finds a sweeter spot between size and sound quality.

Minirig claims you’ll get approximately ten hours of battery life from the speaker before it needs charging again, with a full charge taking two to three hours. The Minirig Mini is an interesting proposition: the stark design will be appreciated by some, its small stature will be attractive to the space-conscious, and the sound is solid. What makes the Mini difficult to recommend, however, is that some (admittedly larger but still very portable) rivals have both significantly better audio quality and greater versatility. Compared to similarly-priced products, such as the Ultimate Ears Wonderboom, it isn’t quite as insightful across the board. We’d like more texture to each instrument, so this speaker can really show off the shimmer of cymbals or the throbs of bass guitars. Its parent company, Pasce originally started as a group of engineering sub-contractors developing underwater robotics, sonar, high-voltage industrial equipment and audio tech, among other things.

Its body is made of anodised aluminum, available in a range of colours, which Minirig says is splash resistant. This is a step down from being totally-waterproof, but a suitable trade in exchange for a 3.5mm connection. The Mini feels well made, but isn’t the most attractive wireless speaker we’ve seen. It gives off an air of utilitarianism in contrast to the more vibrant aesthetic of kit such as the Ultimate Ears Wonderboom.

With some of these competitors coming in at an equivalent or even lower price, it means that, in terms of performance for pound, we are left wanting more for a little less. Some of those upper-midrange notes are also harsher than we would like. They have an unnaturally coarse cutting edge to them, which leaves you recoiling a little at each draw of the violin’s bow. This is only exacerbated at higher volumes. The low beats are balanced well against the rest of the frequency range, though; playing Radiohead’s The National Anthem, the squeals and parping brass ensemble that takes control in the middle of the song are matched judiciously against the low-pitched bass guitar and Thom Yorke’s ghostly vocals.

After a few days of running in, we get down to testing by pairing it with a MacBook Pro and an Astell & Kern Kann hi-res personal music player, and streaming lossless music using Tidal. Using the latest technology and high quality design we bring to you the MINIRIG 3 bluetooth rechargeable speaker. All this works relatively well, and although the app isn’t quite as stylish as some of those from rival companies, it is very straightforward. There’s little room for confusion in using any of the controls.
