I liked the sound quality; it was loud enough to drown out most of the outside world and that’s one of the things I look for in a DAP. The highs were a bit shrill so you might have to adjust the volume to compensate a bit. There's an EQ setting too, though you can't manually adjust the levels. The presets still did the trick by adjusting the levels as best as possible. The result was a decent amount of thump.
The FM radio worked perfectly and the reception was quite good. It takes 15-18 seconds to scan and store the channels, but that’s not a big deal. Another feature included in the 770V is an integrated voice recorder that has quite a good range.
The most interesting part about the Panasonic SD770V is its battery. On a single charge it lasted two whole days. If you’re wondering, it wasn't just a few odd hours of usage; it ran non-stop for a little under 48 hours. About 44 hours was about the time I clocked it in. According to the manufacturer, a brand-new, out-of-the-box player should give three full days of usage. In case you do run out of battery (doubtful), a 10-minute charge would give you about 3 more hours.
The Bottomline
I like this player. It’s easy to carry around, I can use my own earphones, and though the bundled set may look a bit odd, they sound fine. And while the proprietary file transfer software is upsetting, it’s nothing one can’t get around. The easy navigation and the smooth touch-sensitive scrolling are definite bonuses. The SD770V costs just Rs 2350 with no memory card, Rs 2550 with a 1GB card, and Rs 2750 with a 2GB card. I think those prices make it definitely worth a look.
I got this player from importstuff.co.in. I got their number from the site and called them up and they delivered the product. They're very reliable. I should say I'm more than happy with the player and it is exactly what this review describes it to be and has more features than mentioned here (non-stop 12hrs voice recording!). It cost me exactly Rs. 2750.
