What to know before buying

Listing details to confirm

Listing details are inconsistent: it identifies USB and USB-C wired connectivity but also lists Bluetooth range, while power is described as corded despite a requirement for four lithium-polymer batteries. The listed 60-watt maximum output, mono output mode and two audio channels are also not explained together. Dimensions are given as 12 x 12 x 3.45 cm with 226.8 g, while another weight entry says 227 g and another dimension entry gives 10D x 10W x 10H millimeters. Confirm the relevant configuration and measurements in the selected listing before buying.

Who is it for?

A good fit for

Home-office users who want a wired speakerphone for computer meetings.
Small tabletop groups that can sit within the claimed 3m microphone pickup radius.
Buyers who value a compact meeting device that the listing says can fit in a bag.

Less suited to

Anyone needing a water-resistant speakerphone.
People who need a wireless-first or battery-powered setup, given the listing's conflicting power and connectivity details.

Customer feedback highlights clear, loud sound, perceived noise reduction, easy setup and use with MS Teams. These impressions align with the listing's four-microphone and voice-enhancement claims, but do not establish performance in every room or call setup. The overall rating distribution is mostly positive, with a smaller share of middle and low ratings, so experiences are not uniform.
