This can be for approximately 6 EUR no "sound miracle" and "technical masterpiece" expects, has been clear to me before purchase.
Nevertheless, the "yield" was then sobering!
Worked headphones (I've bought two because the listeners of my wife slowly but surely fall after nearly 3 years also apart) still clean packaged and processed, I opened the first package, freed the headphones around him so because right in my iPhone 4 zustöpseln. Try for something already (average size of the in-ears) sitting extradition variant very well - also in following subsequent five days now ongoing use them sit still very good, feel comfortable in the ear to.
The sound is, as expected, "OK"; underwhelming but not bad - for my needs ("overtones" of the soundscape in bus and train) absolutely OK! Because of that they sit very well with me, they dampen external noise then very good way - I get hardly with the train announcements at about 40% volume setting on the iPhone! Otherwise, the sound is more bass-poor and treble could be better.
But you have to watch something - is given to the listener deep into the ear, emerges only arg dull sound - something "instinct" is already asked. ;-)
The connection itself is more "careful" to enjoy; it may happen that when you connect something turns in the player, Smartphone or headphone jack of the computer, causing noise and common creaking noises.
This shows then but rather "cheap" processing!
The disillusionment followed then the 2nd device - this would only "sun and wind from behind" - in two iPhones they ran certainly not only with luck, the PC output. Either remembered headphones out, it just came noise or it was "radio silence" - a clear case for return!
In summary:
+ Delivery by PRIME on the following day
+ Neatly packed
+ Three different sizes of in-ear plugs
+ Very good damming external noise
O sound ok / expected
- Connection seemingly unclean processed / susceptible
- 1 2 devices defective
- Little bass / treble little to overall
Conclusion: When both had worked, I would have been satisfied (4 stars) - especially in this price range - so rather remain disappointment left (3 stars).
