OK sound quality, durability mies

I bought the headphones due to the fairly good reviews. Previously I was using more than a year, the MDR-EX082 Sony that came with the Sony Walkman NWZ-A818. The sound quality is the MDR-EX082 really top notch, but was due to an intermittent contact on the lookout for new head listening. So I finally came up with the model Sony MDR-EX35LPB and am pretty disappointed. On the one hand the quality comes nowhere near to that of the MDR-EX082 (which can be in this price range do not necessarily expect) and secondly, the durability is much worse here. After less than 2 weeks I had a loose connection directly on the left speaker. And although I always Bypass good with my head listening (connections are never under train and headphones are always carefully stowed). I also used this only 1-2 per day to commute to work (about 30 minutes).

Contraindications:
- Low durability
- Mediocre sound quality
- Poor comfort (do not sit so well and are difficult to introduce into the ear canal, because the head is very small and slips repeatedly)
- Small cables -> increased sensitivity

Pro:
+ If I unfortunately nothing a ...

All in all, my conclusion is rather disappointing. The price is OK and I would also agree with the sound quality, but if the product would not be so terribly sensitive. Unfortunately, the favorable price range is too strong impact on the overall quality. What good is a more attractive price, if I have to two weeks later to buy a new product?
For the poor durability, but the "acceptable" sound quality is 2 stars.

PS: If I had the headphones within 2 weeks actually able to return, even though they were already in use? I am thinking above all of the "hygienic" component.
