HD-662 F : Great value for money

The construction seems rather solid considering how cheap they are. The design appears to mimic the way the K2XX series from AKG were made.

The arch clamping force is rather strong, it make the headphones feel rather tight on the head. I couldn't use them for more than 2 hours in one sitting due to the clamping strength. On the upside, you could run into a wall and they wouldn't fall down.

The sound quality is also rather surprising considering the price of the headphones. Kind of mid centric with a bass that isn't exactly prominent. The highs seem to be pretty much in the right place. Staging isn't perfect but it's well contoured - again - for this value.

Bottom line - if you're on a really really tight budget, these will do as temporary studio headphones, even say 'hi-fi' listening headphones.
