We've had the good fortune of putting a Sony NWZ-A829 through its paces over the last few days. Remember, that's Sony's top of the line, 2.4-inch, QVGA Walkman with stereo Bluetooth A2DP and 16GB of flash. With Sony CEO, Howard Stringer, ceding portable audio victory to Apple, we had high hopes for the NWZ-A829 as an out of the box video player. After all, Howie said 9 months ago, "We have worked very hard to catch up so that in the age of video we will not suffer as much as we did in audio." So how did it do? See our take after the break.

Update: We finally made it through a single battery charge (it's that good). Ours lasted 24 hours and 15 minutes under a constant load of about 1 hour of video, 4 hours of Bluetooth-enabled audio, and then another 19 hours of tethered audio.

Remember all that Walkman hotness that Sony hit Japan with last week? Well, as anyone might've guessed, it's headed Stateside soon for your earbud consumption. In addition to the new NWZ-A820 series flagship (pictured), Sony has the NWZ-A720 series, which cops the looks and specs, but loses the Bluetooth of the A820 players. Both players have roughly 10 hours of video battery life, and 36 hours for audio, with 2.4-inch QVGA screens and capacities ranging from 4GB to 16GB. Meanwhile, the new NWZ-S710F skimps on the sexy looks, and only sports a 1.8-inch QVGA screen, but adds built-in noise canceling. Codec support for all the players includes protected WMA, unprotected AAC, MP3 and H.264 video. The full model rundown is as follows, everything will be available in March:

• NWZ-A828K - 8GB, black, Bluetooth, DR-BT21G Bluetooth wireless headphones, $270
• NWZ-A829 - 16GB, black, Bluetooth, $320
• NWZ-A726 - 4GB, black and pink, $150
• NWZ-A728 - 8GB, black and pink, $200
• NWZ-A729 - 16GB, black, $300
• NWZ-S716F - 4GB, silver, red and black, $150
• NWZ-S718F - 8GB, black, $200

One more shot after the break.

After the European PR agency seemingly jumped the gun, we finally get some actual press and hands-on shots of Sony's newest video Walkman. The NW-A820 series as it's known in Japan does everything its other NWZ-A820 brother can do in Europe (and presumably the US) only with that icky ATRAC and SonicStage baggage in tow. Sony also announced a new ¥20,000 (about $186) VRC-NW10 cradle with video-out and trick little video-in capability for real-time MPEG-4 recordings straight back to your A820-series player. A SRS-NWT10M external speaker is priced low enough at ¥3,000 ($28) that every teen-age jackass riding the subway will have one. Japan will see the new players in black, white and pink and in 16GB and 8GB models priced at ¥38,000 ($354) and ¥28,000 ($260), respectively. Check the gallery for hot A820 on iPod touch action.

Having successfully fought HD DVD to the death, Sony can now focus its attention on you know who with the release of their bigger, badder NWZ-A820 Walkman. Sony's followup to its 2.0-inch A810 (pictured) media player boasts a 2.4-inch QVGA display, up to 16GB of flash, 13.5mm EX headphones, Bluetooth stereo audio, and up to 10-hours of video (H.264/ACV and MPEG-4 support) or 36-hours of music (MP3, AAC, DRM'd WMA, and linear PCM supported) playback off beefier battery. The A820-series will ship in black, silver, gold, and pink in NWZ-A826 (4GB), NWZ-A828 (8GB) and NWZ-A829 (16GB) models all hitting Europe starting this April for undisclosed prices. US too if that FCC filing is any indication. Pics as we get 'em.

Update: Adding insult to mystery, PRWeb has pulled the press release for the NWZ-A820. Jump the gun did we? No worries, we kept a copy which is now available after the break. Still no pictures, unfortunately.
