THE VERDICT
Who says you can't improve on perfection? The Sonos Era 100 is the new replacement for the much heralded Sonos One speaker. Does it offer improvements? Absolutely! With Bluetooth and Wi-Fi connections, voice assist and extremely loud playback, the Era 100 lives up to the usual Sonos hype with sound that delivers.

Move over Sonos One—there’s a new kid on the block and its time has come. The Era 100 is one of two new products from Sonos, the other being the larger, pricier Era 300. The Era 100 boasts an array of features that address many complaints from earlier products.

THE VERDICT
The little KEF LSX II is a remarkably capable and versatile speaker that will amaze you with big, audiophile-caliber sound.

KEF's little LSX II exudes quiet sophistication, which begs a question: Is it a lifestyle speaker or an audiophile speaker? It's both, actually—and why not? The cantaloupe-sized wireless speaker is the British audio titan's latest self-powered "just add music" solution and it packs a punch, drawing on extensive signal processing to optimize performance, with the goal of delivering near full-range reproduction to a very high standard. The system also boasts a proprietary app that integrates setup, control, and streaming from virtually every important service—including Tidal, Spotify, Qobuz, and Amazon Music—or your own file- or disc-based music collection.

THE VERDICT
If portability and sound quality are important to you, the Sonos Roam smart speaker is an outstanding choice.

When a company known for inventing the multiroom speaker announces a new fully portable model, we sit up and take notice. The new Sonos Roam ($169) is an ultra-compact, IP67 water- and dust-proof smart speaker that weighs less than one pound and links with your phone or tablet via Bluetooth 5.0. But that's not the whole story. The Roam can also connect with your home Sonos ecosystem, automatically making the switch between Bluetooth and Wi-Fi as you come and go.

Some ergonomics issues
Inconsistent system stability

THE VERDICT
The B&W Formation system performs admirably in a number of respects. But unreliable stability, limited processing features, and no HDMI input make it a less-than-ideal option for 5.1 surround sound.

Blame it on Sonos. In the early 2000s, at what was then the Los Angeles headquarters of the Stereophile Guide to Home Theater, we were visited by a gentleman from that then largely unknown company who had a product he was eager to promote: a wireless speaker in a single, relatively compact box. I politely declined. It wasn't a good fit for our publication at the time, but I should have at least asked him about stock options!

THE VERDICT
Though it doesn’t come cheap, Naim’s newly revised Mu-so brings true audiophile sensibilities and surprising wallop to a well thought-out and full-featured wireless speaker.

The original Mu-so wireless music system released in 2014 was a first in the emerging "lifestyle audio" category—a truly high-end, wireless, multiroom speaker from one of the most respected brands on the planet. I auditioned the Mu-so back then, and what I remember most from the unboxing was its nearly 30-pound heft, and the manly, finned heatsink that ran the width of the back panel and threatened to cut any flesh that wandered too carelessly in its direction.

It’s not every day that a new consumer electronics category comes along that has an adoption rate projected to be faster than that of any other device, including smartphones, computers, TVs, and radios.

Some 56.3 million smart speakers are projected to ship this year, nearly twice as many as last year and 10 times the number shipped in 2016, according to Canalys. In the first quarter of 2017, only 7 percent of U.S. households had smart speakers. By the end of 2020, 75 percent are expected to have them, according to Gartner and Edison Research.

Lackluster sound quality

THE VERDICT
The Mondo+ is a versatile internet radio that offers easy access to a multitude of streaming sources, but we expected better sound quality for the price.

My first thought was “clock radio” as I lifted the Mondo+ out of its box. It’s tough to gauge the heft of a product from a picture, so I guess I was expecting something a bit more substantial. Even so, the plastic-encased Mondo+ is nice and compact—about the size of a loaf of bread—and attractive with a smooth gray finish and large color display that serves as a gateway to wireless streaming options and system settings, including—you guessed it—an alarm clock.
