What is it?
A portable-yet-powerful wireless speaker with in-built power bank.
Good points?
Similar in design to an old-school boombox, the 31-centimetre (12.2 inch) unit incorporates an angled handle at the top for easy pick-up and movement. Weighing in at a little over 2kg (4.8lbs) the device is portable but feels robust and won't be susceptible to damage.
Featuring four tuned speaker drivers – two 20W and two 10W – delivering a total of 60 watts and two passive radiators, the audio output has plenty of oomph to fill most household rooms without compromising sound quality.
A 7,200 mAh battery allows up to 12 hours of playtime from only three hours of charging via USB-C cable. This lithium-ion battery also doubles as a power bank through its USB-A port and provides enough juice to charge a typical smartphone or tablet.
Other features include microphone for hands-free calls, IPX6 rating for usage in rain or by a pool and compatibility with Siri or Google assistant for voice-free operation.
Stereo sound can also be achieved by wirelessly pairing two Quattro speakers together which is ideal for any larger gatherings.
Bad points?
The audible notifications for low battery are not as clear as they could be – during testing I only learned the device had fully discharged when the music stopped.
Best for ...
Those looking for a portable speaker that packs a bigger punch than those typically associated with battery powered devices.

Avoid if ...
You are seeking a speaker that can easily fit into a bag alongside a laptop or other devices as this unit is a tad on the bulkier side.
Score: 8/10.

Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
