According to BenQ the eVolo is the first portable speaker using electrostatic technology to reproduce sound, with a stylish design featuring foldable metal side wings and bi-directional sound.

It streams CD-quality audio via aptX and Bluetooth, and BenQ says performance is "particularly well refined" in the medium- and high-pitch sound range. The speaker's thin-film diaphragm projects bidirectional sound, radiating a high level of audio detail from every angle.

Bose celebrates its 50th anniversary with the launch of 12 products making part of its SoundTouch wireless speaker lineup, including the 2nd generation of one-piece SoundTouch systems.

All SoundTouch systems feature one-touch integration with multiple music services, including Deezer, Spotify, iHeartRadio and Pandora. Setup is streamlined via improved mobile device app, and AirPlay compatibility allows iDevice connectivity.

The audio systems connect directly to the internet, meaning no additional equipment is required.

“Music is at the heart of almost everything we do,” the company says. “So we asked ourselves why the world wasn’t playing it more at home. Like so many things, it’s become too complicated and SoundTouch systems change that. We put all your music in one place. You control it in the easiest way available, and personalise it for what you love and how you live.”

Headphone-using audiophile customers might be interested in the HD-DAC1, the first headphone amplifier from Marantz featuring an integrated DAC, as paired with technologies from the company's Premium 11 series.

It drives high-impedance headphones of up to 600 ohm via 3-level gain control, Marantz HDAM modules, the CS4398 DAC and fixed and variable RCA outputs.

Parrot updates the Zik wireless headphones and reveals the Zik 2.0, a collaboration with French designer Philippe Starck featuring improvements on both design and battery life fronts.

The headphones connect to mobile devices and PCs via either Bluetooth 3.0 or NFC, and retain some features from the previous version-- namely noise canceling capability (which Parrot says is improved via multiple built-in microphones), touch-sensitive earcups for swipe-based music control and head detection to stop the music whenever the user removes the headphones.

Audio performance comes through a 40mm neodymium driver and a built-in DAC handling 24-bit-192kHz audio. As for the battery Parrot promises 6 hours of use in regular wireless mode and up to 18 hours in wired flight mode.

A P300 special, the combination jacks allow for easy integration with TVs and AV receivers, increasing the number of home entertainment scenarios installers can introduce.
