November 17, 2021

Hidizs S9 Pro  portable balanced DAC & amp has hit the market globally over half a year ago and has been popular in the Hi-fi audio space. Its popularity is undeniable as professional audio reviewers have unanimously provided high ratings. The product has been frequently sold out on the Hidizs official website, and authorized resellers continue to scramble for more inventory.

So what’s so special about this portable balanced and SE amp/DAC dongle? For starters, it uses an ESS ES9038Q2M DAC chip, supports up to 32bit/768kHz PCM, native DSD512, and is designed for use with Windows, Mac OS, Android, as well as iOS devices. It’s about the size of a USB and contains both single-ended 3.5mm and balanced 2.5mm outputs with incredible drive ability (200mW BAL/100mW SE) that’s more than able to power all full-size headphones.

And now, Hidizs S9 Pro Red Copper Limited Edition is available. 500 units only worldwide. The S9 Pro red copper’s configuration is the same as the original S9 Pro DAC AMP, the aluminum alloy CNC integrated shell has been replaced, however, with a one-piece pure copper shell.

Crafted from 99.9% copper content in 90 minutes with five-axis CNC engraving, it’s highly polished and brushed to perfection, making for a linear surface texture protected by a PVD film, which gives the red copper its silky look.

As a result of the highly skilled manufacturing process and environmental demands, Hidizs S9 Pro red copper USB DAC/amplifier dongle is a limited edition collectible item with only 500 units available worldwide.

As most smartphones have done away with the 3.5mm headphone jack, dongles now connect to smartphone via Type-C or Lightning connectors. The audio in your mobile phone is decoded and played by the audio, and then output through the 3.5mm/2.5mm audio port to your earphone. The audio quality is hence greatly improved and for an unrivaled listening experience. For music lovers with a penchant for audio quality, there is really no other better way to listen to such beautiful music. 

Thanks to powerful hardware and a mature supporting ecosystem, mobile phones have become ideal music playback devices. Streaming apps such as Spotify, Sony Music, Apple Music, HiBy Music, Tidal, Pandora, Amazon Music, etc., can now provide a large number of tracks in 24bit/32bit or higher bit rates. But it’s near impossible to unleash their full audio potential if you use wireless earphones to listen. Use the Hidizs S9 Pro portable USB DAC/Amp dongle to act as an intermediate between your smartphone and high-quality earphones, and you’ll be surprised by the tremendous improvement in the audio quality.

Think of it this way,  the DAC AMP dongle carries out the functions of an external professional audio receiver for mobile phones and it’s a portable, but powerful, audio amplifier that makes it a must-have for music lovers worldwide.
