ESS Technology Comes Out to Play With the LG G5

B&O meets ESS for highest quality audio

The LG G5 was a Mobile World Congress highlight as the company showed it was daring to innovate. The company behind the digital logic inside of LG Gi-Fi Plus audio module had a word with us to show us the difference in quality.

ESS has been in business for a long time, and many will recognize the name from the PC side of its business. They used to be inside many audio cards in nineties and company went aggressively into the consumer business in the 2000s. Since  2015 some top phone manufacturers including LG (with V10 and G5), Vivo, Meizu and Xiaomi used  company’s DAC.

Vivo Xplay5 boasts 6GB RAM and a familiar curved screen

If you need an excuse to acquire a new exotic Chinese smartphone, then how about 6GB of RAM? Not only is Vivo’s new Xplay5 the first mobile device to announce this spec, but it’s also the second non-Samsung device — following the BlackBerry Priv — to pack a screen that’s curved on both sides. Judging by its familiar metallic design, you’d easily think that the Xplay5 is the bastard child of the Galaxy S6 Edge (front) and the iPhone (back) after a one night stand in Dongguan (the S7 Edge’s chamfer isn’t as shiny). Despite the unfortunate similarities, this is still a surprisingly decent product in terms of hardware and specs — much like how its predecessor, the Xplay3S, managed to wow us a little over two years ago.

ESS Technology Comes Out to Play with the LG G5

SABRE HiFi DAC and Headphone Amplifier Selected for Innovative LG HiFi Plus Friend Module 

Milpitas, California – ESS Technology, the industry leader in HiFi audio and analog design, today announced that its award-winning SABRE Digital to Analog Converter (DAC) and Headphone Amplifier technology have been selected for the LG G5 HiFi Plus module introduced at Mobile World Congress 2016. The ES9028 SABRE DAC and SABRE9602 Headphone Amplifier were selected to provide a superior HiFi audio experience courtesy of ESS’s superior sound quality and industry leading dynamic range. ESS’s audiophile technology easily supports the industry’s most popular high resolution and lossless audio formats including FLAC, ALAC, AIFF and WAV.

“It’s an honor for ESS to extend our collaboration with LG with this groundbreaking approach to smartphone features and design,” said Dan Christman, ESS’s Chief Marketing Officer. “This sleek modular approach will give consumers the opportunity to access top-notch audio while still appealing to photographers, gaming enthusiasts and more. With the G5, LG has succeeded in challenging the status quo in the high-end smartphone market.”

The LG G5 and its companion “friend” modules were recently announced at Mobile World Congress in Barcelona and have already received numerous awards for innovative designs and features including the Top Tech of MWC Award in the audio category from Digital Trends. The innovative modular design gives the LG G5 the ability to transform into a digital camera, HiFi player, and more while keeping its traditional removable battery in a full metal uni-body design.

The technology inside the LG HiFi Plus module was carefully created to provide an innovative portable HiFi DAC audio player that meets the needs of consumers wanting audiophile grade performance that has traditionally only been available through large, expensive component devices. The LG HiFi Plus supports 32-bit, 384KHz high definition audio playback and can be used either as a module with the LG G5 or as a separate HiFi DAC by connecting to any smartphone or PC.

Two New Accessories Give LG’s Modular Smartphone Super Powers

You probably know by now that the LG G5 is a modular phone. The bottom of the device is removable and can be swapped with different accessories that multiply the phone possibilities. A couple of them caught our attention: a little module that will amaze audiophiles, and a bulky module that adds physical camera buttons.

The official name is LG HiFi Plus and plugging it into the G5 expands the size of your device by a little less than 1.3cm. In exchange, it offers an spectacular improvement on the music you can listen to.

Inside the module there is a Sabre DAC 9602C. It’s manufactured by ESS Technology, a veteran Californian company that sells custom HiFi solutions. The Sabre 92602C was introduced during CES 2015 and its specifically designed to improved sound quality on smartphones and tablets.
