You need to try audio Technica best mids and vocals period and I'm a hd650 die hard fan.None of those were keepers, they might be interesting to hear for few hours, but not for weeks and months. One exception would be HD800S, that one is really incredible straight out of WA2. But it's very specific headphone, I just wasn't using it much and I won't be keeping this expensive headphone to listen to it few times a month.
The 650 on good chain is insane in terms of mids especially. Even the Clear can't beat it. Listening to something like Black Keys is still better on HD650 than on Clears.
Expensive doesn't mean better
I own the new ath awtk model you might actually prefer the warmer version the ath awas
