Value ok. 6

I prefer normal headphones like these intra (less comfortable).
I've had several different pairs of Sony in recent years.
The first I had were the best, I forgot the name of the model but it is not found anyway since it was a model that comes with the second generation MP3 player (2005), the headphones were "tour neck "and the sound quality was excellent (clear sound from bass to treble).

I have since had other pairs such as MDR-E 10 2 years ago, the quality is a little worse (less serious, lack of choker) but it was still really good (the clear, light to wear) and cheap (~ 12).
In E829V model, compared with E-10, a knob for volume is gained, a storage box and a small pair of foam for comfort, however, the wire is now shorter, the look is less friendly and they are a little heavy and big to wear (careful if you have small ears) .For sound, it is less clear than for the E-10 especially acute, however serious and senior medium are much better on the other side we lose a little lower medium.
In the end it looks pretty good headphones for all that is electro-acoustic (pop, rock, soul, electro, variety ...) but less for pure acoustic (classical, jazz, voice ...), it is then, that losing quality since 2005 but it remains excellent in value (12!), reliability level, all my pairs are between 10 months and 1 year and a half on average, it's okay given the price (always less 15).
