I'll mention again, relatively modern Samsung's have a blue light filter, might help with late night reading, doesn't seem to do a bless'ed thing for battery life.
While Beats do appear to be something of a confidence scam, I'd be interested in hearing your experience of them, but it seems you're somewhat between platforms for now.
I consider my 4gb blue iPod Nano (no video) my old standard for testing. Like I said, the Sennheiser HD 205's are a little flat, and I don't trust tech blogs anymore.
I remember there used to be absolutely brilliant head to head tests where they didn't care who made the products, and they'd have stars down the list.
Nowadays, it's all clearly sponsored content. Damn shame.
I don't know how you feel about the group, but Rage Against The Machine's 1992 self titled album is considered a good test album, apparently it was well produced.
So I like the tab line, and I believe they are far less expensive than apple. I'd say avoid the poo out of the ellipsis line, but you're unlikely to come across one.
I do miss my tab 3, which was killed by my own stupidity. Avoid that, if possible.
