Handset's digital to analog converter promises crisp sound reproduction that reduces ambient noise by up to 50 percent.
LG hopes the path to phone buyers' wallets is through their ears.
The Korean electronics giant on Wednesday said the V20 -- its next-generation flagship phone -- will feature a 32-bit Hi-Fi Quad DAC (digital to analog converter) in what LG called an industry first. LG said the DAC produces a crisp and clear sound reproduction that reduces ambient noise by up to 50 percent.
The V20 is the follow-up to LG's V10 phone, which rolled out last October. The company is expected to unveil its new handset on September 6 in San Francisco.
In addition to its DAC, the device is also expected to be the first phone to sport the new Android 7.0 operating system, known as Nougat. Typically, Google is first in line with a new Android version on its Nexus devices.
