The sound quality, even at c. 128 kbps, can be very good:

Also, one of hydrogenaudio’s recommendations is –V6 (c. 115 kbps): http://wiki.hydrogenaudio.org/index....2C_small_sizes.

And the relationship between battery life and kbps? Well, here is one claim from Sony: http://www.sonyinsider.com/2008/08/1...aland-website/.

According to this ATMEL datasheet, the decoding power doesn't vary much with bitrate.

That means that the major hit on power consumption with bitrate differences is going to come from I/O power. And that most definitely scales linearly with bitrate.

The question is, how much power is consumed by I/O in relation to the rest of the system? The amplifier powering the audio is probably going to use more power than variations in I/O, and the screen is using more power than either of them.

So, I'd guess it's probably a %10-20 hit moving from 128k to 320k, not a huge hit, but noticeable if you constantly use the player.

No wonder why my battery doesn't last the longest of times, even though the screen is on the lowest setting .

Flac and 320k MP3 here. I can sure hear the difference with my Audio Technica A900's on, bad MP3's sound awful and even clip. With my JVC marshmallows I can't really hear much of a difference at all, but I broke them yesterday .

Taking my A900's into work today again always fun lol...
