Review : AKG K550

"Reference Class" Headphones.

Initial impressions :

Sounds like these....

The ADDIEMs are
- sound stage below average
- heavy hitting quick bass, clean
- extended treble that doesn't really sparkle(or add air)
- dry, sometimes robotic vocal

Hey not bad, maybe these are for me after all....

Impressions about 2~3 minutes later :

- flat soundstage with no imaging
- wtf vocals like staring at the sun
- ok the review ends now I have to take these off right away!

Verdict :

My ears had severe placebo channel imbalance, loss of hearing on certain frequencies for the rest of the day.
