Sony Network Walkman NW-HD5 review (Black)

Thanks to ID3 tag filtering and the Initials Search, wherein every track beginning with a selected letter pops up instantaneously, it's easy to find tracks, though you can't play all albums or all artists. The HD5 has a bookmarking feature that doesn't actually bookmark specific points in a track as you would do for an audiobook. Instead, a bookmark is actually an on-the-go playlist--you can create up to five on-the-go playlists with 100 tracks each. This is a nice extra, but you can add tracks only while they're being played back (hold the up button) and not from within the music library. And unfortunately, you can't transfer those bookmark playlists back to SonicStage on your PC as you can with iPod/iTunes. However, you can edit your bookmarks--that is, delete or move tracks and even assign one of dozens of basic icons to a bookmark--within the player interface.

While the HD5's simplicity gives it a throwback aura, the device's inner workings are anything but old-fashioned. The USB 2.0/Universal Mass Storage device also features velocity-sensitive G-Sensor shock protection, which means the hard drive will automatically disengage if it is dropped. The same G-Sensor allows the HD5 to automatically orient the screen so that you can use the device in Portrait as well as right- or left-handed Landscape mode, though Landscape mode, reminiscent of the HD1 and HD3, doesn't do much for us. This works only when you power on the device while it's in your preferred orientation, but you can also manually set the orientation.

Most of those who have followed Sony's progress along the MP3 freeway have noticed that the Windows-only SonicStage software has gotten easier to use and is more effective. It's still not our first choice for a jukebox application, but unfortunately, you're committed to using it for all music transfers. This includes MP3s and songs purchased on Sony's Connect. Although the HD5 will mount as a hard drive even on Mac OS, you can store data using only this method of transfer. Though it takes a while, those who have a stable of non-DRM WMA files can convert them in SonicStage into ATRAC3 for use on the HD5. Unfortunately, the device will not play back WAV, AIFF, or lossless formats natively.

As digital music stores grow in popularity and usefulness, understand that you're also committed to Sony's ATRAC3-powered Connect in this arena. The site isn't ideal--the interface isn't well laid out, and the promoted track selection could be deeper--but it maintains a dark-horse persona, given the popularity of iTunes and WMA-supported sites such as Napster. We're unsure if the Sony Network Walkman NW-HD5 will be able to handle subscription-based downloads if Sony ever introduces a Janus-like system.

The Sony Network Walkman NW-HD5 powers on the instant you press any button. It takes a standard 6 seconds to boot, and you'll start up on whatever screen you last viewed. The first time you access the hard drive, you'll get a slightly annoying "access" message that appears for about 3 seconds; you'll get this message occasionally during use. However, the overall navigation--from scanning through tracks or adding tracks to a bookmark playlist--is as smooth as butter.

In informal testing of the better-sounding MP3 players on the market, the HD5 consistently came out on top. It's a great-sounding player with a low hiss factor, a reasonable bass, crystal-clear highs, and an overall warm sound. The only downside is that it doesn't get as loud as some other players, such as the iPod. The so-called VPT Acoustical Engine includes Studio, Live, Club, and Arena environments, while the six-band equalizer includes presets for Heavy, Pop, Jazz, Unique, and two custom settings, as well as two additional digital sound settings. Do note that the first two sound items (VPT and six-band EQ) will work only with ATRAC3plus files, not MP3s. All in all, the effects and EQ give a measurable presence to the music, and we appreciate the ability to preview each type of sound before you select. There should be a Quick key to toggle thorugh the sound effects and EQs, though. DJ, producer, and audiophile types will no doubt be entertained by applying the DSP effects.

Perhaps the Sony Network Walkman HD5's most intriguing attribute is its amazingly long battery life. While Sony has rated battery life up to 40 hours using 48Kbps ATRAC3plus tracks, CNET Labs was able to get a consistent 28 hours per charge playing a 128Kbps MP3--still an impressive figure that beats out Creative's Zen Touch as the current high-capacity king of juice. What's more impressive is that you can swap out the HD5's battery, so if you're going on a long trip, this Sony player should be the leading candidate on your list of trusty travel companions. The HD5 will charge via USB in 6 hours, while the AC adapter will charge the battery 80 percent in 1.5 hours. Transfer times for MP3s using SonicStage were a blazing 8.6MB per second over USB 2.0.
