Super headphones, but only mediocre durability

I would recommend the Philips SHS 4700 Clip On Headphones definitely. Over a period of 4 years, I've already bought 2 of them (now the 3rd were due for the next 2 years). Sadly you can wait for the earphone after 2 years break if you use them in everyday life often. I use my MP3 player almost every day to listen to music and, accordingly, the earphones are badly affected. However, I must say that they are definitely worth its price. I wear them in cold, heat, rain, snow, while jogging, when traveling on the train, in the car as a passenger, while shopping, traveling, everywhere: O) ... in this case there is no problem for me after 2 years time new earphones for an average of 30 euros to buy. ... The main reason why I recommend these headphones is that they can still play very well, in contrast to many other products (also much more expensive) lower frequencies (bass). In most usually only reach high to medium frequencies the ear and you felt like you were in a mini playback show for children. I have tested at least 20 other earphones in the store and even the highly praised renonmierten expensive earphones Sennheisser that lay at 50-60 euros, I could not convince better.

Positive overview
+ Relatively good Freqeunzsprektrum for earphones in this price range; good sound impression with MP3 quality
+ Firm grip; jump and run without losing the earphones
+ Light and comfortable; they can wear for hours without noticeable pressure, friction or other factors that may act uncomfortable in the long run (much more than 5 hours may be stuck to the strap behind the ear, however, by a slight pressure noticeable)
+ Good Reinforced signal (good amplifier; the sound is loud and crowded, the signal is completely and without any noticeable loss of the listener; other devices partially in the same price class are not even capable of a signal from the output of the MP3 player up to to fully convey the ears without interference)
+ Easy on the ear (as an on-earphone is an air cushion between the ear and the listener, which makes for noticeably lower burden than earphones in the ear canals)
+ Good value for money (the normal price is 30 Euro)

Negative Overview
- Durability with frequent use in all walks of life mediocre (retaining strap can after several years baggy, their voltage is lost and you are no longer so close to the ear, loose contacts on jack may arise; cable very thin and flexible, but they also very vulnerable makes)
- There are open headphones, ie disturbing noises from the environment are still clearly perceptible while listening to music and vice versa also the noise of the earphones for the environment is above average perceptible; I could talk to people without me problems sometimes, while I was listening to music on earphones this; Turning the level of the MP3 player at maximum has one little speaker that will entertain an entire room with music)
- The earphones are more conspicuous than, for example, in-ear headphones or a simple button Earphones (well, here you have to decide: will you earphones with good sound quality, or rather more discreet earphones; both are to get hardly for the price)

NOTE: The earphone cable and the connection to the jack have something changed in their shape and material composition over time. Through savings there was little material deterioration.
