Sprint Product Ambassadors: HTC One M8 Harman-Kardon Edition - What Makes it Special?

Sprint Product Ambassador


Ah, the M8 HK, a superfly hi-fi version of HTC's newest flagship.

Yes, we know you well now, and yes we love you.

But we know that's it's not just your beautiful black anodized aluminum finish with "champagne" accents that makes you great.  You are so much more.


First off, clearly there are some software enhancements that were done to bring a premium audio experience to the M8 HK.


Clari-Fi automatically restores the quality of compressed digital music by uniquely and intelligently rebuilding the lost audio content.  Clari-Fi is a patented technology, based on harman/kardon’s unique knowledge and expertise in acoustics, recording, and playback technologies.  Music will sound cleaner, crisper, wider, and more

Features include:

    • Auto detect - Applies a proportional treatment based on the measured quality of the input signal
    • Transient enhancement - Sharpens the attack and decay of transient signals such as percussion
    • Vocal enhancement - Isolates the central focus (e.g., vocalist or soloist) and sharpens their time and frequency responses
    • Stage widening - Spreads the sound field outward, preserving the center image
    • Reverb fill - Restores the natural reverb tail which is lost in compression
    • Frequency fill - Fills temporary holes in the spectrum caused by compression

Works with all compressed audio formats – MP3, AAC, Radio, Playback, or Streaming.

The Clari-Fi experience includes:

Low & high frequency extension

Improved realism & fidelity

Wider sound stage

A new life for compressed media files

And.. it’s always on – – nothing to select or configure



Provides a more lifelike headphone listening experience

Defaulted to ‘off’ because:

>Perceived benefit will be specific to the individual

>Benefit will be dependent on how the audio content was
originally mixed

How does it work?

Virtual speakers are created at angles from +/- 30 to +/- 45 degrees

>Provides accurate, person-independent localization

>Does not impose any tonal imbalance or coloration

>Frequency responses are smooth

>Processing complexity is very low


Second, the speakers on the M8 HK were tuned by Harman-Kardon engineers to provide the best possible sound.

Lossless Playback:

In addition, the HK edition is equipped with lossless (24 bit/192 kHz) HD audio playback — For studio-master sound quality

Special earbuds:

Plus, the HK edition comes packaged with special HK AES premium earbuds (a $149 value!).

Sophisticated design optimized driver system provides a high quality audio experience

Three-button remote with a built-in microphone

Durable cable and earphone plug

Three pairs of silicone sleeves are included

So listen up and find out what makes the One M8 HK so killer; it's all there.. "in the sound".

Until next time,
