A music lover's smartphone

HTC One M8 Harman Kardon Edition

The HTC One (M8) Harman/Kardon Edition offers a sleek, all-metal design and a host of music-friendly features.

If you're a music fan and you've spent time with a smartphone, you probably know that listening to your favorite tunes has never been more convenient. Your phone can store hours and hours of downloaded playlists and albums. Mobile apps for Internet music services like Spotify® and Beats let you enjoy access to millions of songs on the fly. But for the audio experts at Harman/Kardon, convenience isn't enough. That's why they've teamed together with Sprint and HTC to offer this special edition of the HTC One (M8) — a smartphone equipped with special features to make all of those convenient music sources sound their best.

Read our hands-on review of the HTC One (M8) Harman Kardon Edition.

Clari-Fi™ breathes life back into your music

Here's the main knock on digital music, in general: most of it has been "compressed" and "decompressed" by the time it reaches your ears. Much of the data from the original audio signal has literally been removed. Subtle details and dynamics can get squashed, which can make your music sound artificial and harsh.

This special edition of the HTC One (M8) has proprietary Harman technology on board, called Clari-Fi, which helps restore the parts of your music that have been lost. This intelligent sound processing is based on Harman's in-depth knowledge of how human hearing and digital audio compression work. Clari-Fi analyzes the audio signal in real time and corrects problems, so you get fuller, more lifelike sound. It improves high-frequency detail and bass extension and eliminates unwanted frequency gaps. Unlike other "solutions" to the sonic problems of compressed music, Clari-Fi doesn't unnaturally boost or equalize the signal, so what you hear is more like the original uncompressed version. This algorithm even adjusts the amount of restoration it provides based on how "squashed" or compressed a particular song is.

High-res audio

Support for high-res audio

On the opposite end of the spectrum from compressed audio files, there's high-resolution music, which you can purchase and download from a growing number of online sources, such as HDtracks. Rather than being squashed into a smaller file by compression, a high-resolution music track actually contains more information than its CD-quality counterpart. More information translates into richer detail and smoother sound. The HTC One (M8) Harman/Kardon Edition can play high-resolution FLAC files, up to 24-bit/192kHz.

HTC One M8 Harman Kardon Special Edition with AE in-ear headphones

Harman Kardon's AE-S headphones are a big upgrade over typical earbuds.

High-quality Harman/Kardon headphones included

We're also fans of the headphones that come with this music-friendly smartphone. These aren't like the standard-issue earbuds thrown in as an afterthought with some other phones. Instead, you get a special version of Harman/Kardon's AE in-ear headphones designed specifically for use with the HTC One (M8). Featuring sturdy aluminum housings and carefully designed 9mm drivers, they dish out accurate lows as well as crisp highs and balanced mids. The drivers and enclosures work together to keep your music sounding dynamic and alive rather than muddy. A 3-button remote and microphone built into the headphone cord let you control music playback and take calls with ease. The included assortment of silicone and foam ear tips let you find the right fit for long-lasting comfort and proper noise isolation.

LiveStage™ processing for better headphone sound

The HTC One (M8) Harman/Kardon Edition also includes another exclusive feature, LiveStage, which provides more spacious sound when you're listening through headphones. This switchable listening mode creates virtual "speaker locations" to broaden the soundstage. Your music sounds more like it's coming through a home stereo system and less like it's isolated in your headphones.
