i can tell the difference between 128kbps and 192 kpbs. at 128, not all the instruments are heard clearly, and the sound isn't as crisp.

as for 192 and 320 kbps, I ABSOLUTELY CANNOT TELL THE DIFFERENCE, therefore, to save space, i only save songs at 192kbps.

I don't have a very good ear for hearing the difference between qualities, but the idea of having a low-quality sound file annoys the hell out of me >____<
My iTunes shows the bitrate of the files and, as dumb as this may sound, when I see the 128/192kbps quality there, it hurts my eyes.
I'll only start downloading lower quality files when I desperatly need more disk space, it's VERY annoying.

And so, music should only be heard in the best quality.

128 - They sound crackly, and distorted.
192 - They sound decent. Acceptable.
320 - Amazing. So crisp, and the bass lines and drums are much clearer on my headphones especially.

I really noticed the difference when I ripped my own DOUBLE album (official) and downloaded the same album. Everything had a much fuller sound on the version I ripped myself at 320 then the downloaded copy. :eviltongu

Well I use an iPod...so when I am using that everything sounds the same. Through my laptop or a CD in my car though...you definitely notice 320.

hmm i can mostly tell the difference, 128 just annoy me so much...@_@

I really can't. 's why I always rip my files at 160kbps - sounds as good as 320kbps to me, and it saves space, haha =x

As others have noted, I believe a good deal of it comes down to what you are using to listen to your music with. The artifacts of lossy compression can be particularly apparent when monitoring with high quality speakers or headphones.

I keep my collection of music in WAV format for the most part. It surely takes up more hard drive space, and there is a price premium when purchasing digital music online in that format, but it's worth it for me.

I can barely tell the difference. 192 kbps sounds a bit better than 128, but 320 doesn't sound different from 192. I'm pretty much satisfied with 192 kbps.

I use 128kbps AAC because i can fit more onto my ipod LOL. It sounds great though. 16211 songs so far..

Yes. I can also tell the difference between 320 and FLAC/M4A Lossless

i can't tell a single difference
seriously...lols
how can ppls tell the difference!?
they're both the same sounds
lols

I used to not be able too, but now I can tell if something is 128kbs,sounds so baaaaaaaaad... Can't tell the difference between 192 and 320 though.

If you have a quality headset, earphones or speakers you can. I can easily tell between 192 and 320. 128 sounds awful to me. It's crummy.

yes...i can definitely tell a difference

192kbps and 320kbps don't really sound that different to me, while 128kbps is like.. EW. XD

Not really

i don't care much of the Kbps coz my songs are all in 128kbps...I think the higher the kbps the bigger the File Size

No
i can hear the difference between 96 kbps and 128 kbps, but i cant hear the difference above 128 kbps

Between 128 and 192 I can but 192 and 320 sound the same too me.
