Small portable speakers suitable for work meetings have, unsurprisingly, had something of a renaissance recently. Jabra has a neat little offer in the shape of its Speak 750. At £255 (ex. VAT; 306 inc. VAT, or $312.96 from Amazon in the US) it's rather more expensive than the Poly Sync 20 I looked at last month, but it offers many similar features including certification for Teams and Skype for Business.
