Good sound but the quality of the microphone is bad !!!

I bought this helmet Replaces the original that made a sound too metallic.
I was very satisfied with:
- Rendering the sound is excellent especially the lossless with low ok and well-defined treble
- The true control iphone handy though poorly located on the wire
- Ear adapters suitable for comfortable to wear (it is far from the kind of ball ear Koss !!!)

By against big disappointment:
- The microphone is bad, even very bad! compared to the original. Hey Mr Klipsch is also a phone headset !!! A 100 euros headphones are expected to top the (amplifcation, noise reduction) but none of this, my interlocutors tell me hear me less than the original headset.
- The quality of the son of headphones is bad: they are not shielded (we sometimes hear crackles on the very quiet titles (classical genre etc ...)) and I think it is very fragile over time: why yet once does not learn from what was done in the beginning, a good, thick wire with a good jacket.

In short the price I expected better ...
