Voice control is part of the features list as well, as Google Assistant is here to handle your spoken commands and queries. An array of four beam-forming microphones handle both far-field voice recognition and acoustic echo cancellation. All of these wireless connectivity features are available on all three speakers, so you aren't forced to settle for a certain size if you want voice control and other tools.
While there is a Braun app for setup, control and tweaking EQ settings, each of the LE speakers has physical controls as well. There are buttons for actions, play/pause, skipping tracks, volume and Bluetooth pairing. Like many smart speakers these days, there's also a dedicated control for turning off the microphones. When they're disabled, the otherwise white LEDs on the front turn orange, as does the mute button itself. This way you know at a glance if the speaker is listening for your cues. Around back, there's a 3.5mm aux jack if you need to make use of a wired connection.
The main difference between the three units is both size and power. At the top with the pricey LE01, two 5.25-inch aluminum cone woofers, three 2.5-inch radiator drive units, two quadratic 8 x 4.5 inch passive bass radiators and three class-D power amplifiers. With the smallest speaker, the LE03, there's basically one of each of those, and the mid-size LE02 is in between the two. A 32-bit ARM multi-core digital signal processor is on all three models to help with "high accuracy and low noise," and the trio is capable of 96kHz/24-bit audio streaming. If you want to buy two of any of these models, you can use them as a stereo pair with dedicated left and right channels.
The demo room here at IFA was set up in a mostly concrete loft, so it wasn't ideal for making any final judgements on overall sound quality due to the echo. However, based on a few minutes of listening time, I can tell you the audio on the new LE series is very crisp and clear. In fact, I was pleasantly surprised by the clarity. Instruments all stand on their own without being condensed down to a single blob of sound. And because of that, there's dimensionality to the audio that a lot of wireless multiroom speakers don't do well. The Braun LE series also has nice bass for standalone speakers -- the radiators for the low-end tone do their job well. Overall, the revival of Braun Audio makes a good first impression, but it's too early to say if they outperform Sonos without further testing. And I'm sure a lot of people won't be happy with the updated design.
The Braun LE series is set to arrive in October in both black and white color options. The largest unit, the LE01 will cost $1,199 (£1099/€1,199) while the mid-size LE02 will be $799 (£749/€799). The smaller, square LE03 is the most affordable of the group at $379 (£349/€379). As a comparison, the Sonos One is $199 and the Play:5, which most closely lines up with the LE02, is $499. In other words, if the audio turns out to be comparable to Sonos with these Braun speakers, you're paying a premium for the brand and its heritage. Again, that's something we'll have to test when we're able to review them.
