Until then, I'm fine. I test and catastrophe! Horrible sizzle, unbearable noise for the one at the other end of the phone, listening to me is correct, but the microphone did anything! The volume change is not working as it should, the headset connects every second when turned on, short, disgusting! (Tested on HTC Desire, Samsung Gs3, Iphone4, notebook PC, Nokia basic, short, I gave it a shot everywhere!)
So references the product through Amazon. The procedure went well, and after return, I receive another quickly. Same design, ie no one in the photo (I invite you to watch the pictures on google, we see that there are two similar products). I test and BIM! Even worries, a little less violent, but the same!
Disgusted, I referrals to new headset and questioning the Plantronics brand.
So I make me pay this time, and will this morning in a large sign in the city.
I take the same product: design identical to the photo, finally! And then: better finished product, transparent rubber that's not all dry and hard, charger worthy of the name, in short, THE M25 true!
And oddly, everything works, volume, microphone, her best, she speaks into the ear to warn us, everything is finally great, and the headset is much more beautiful and less cheap!
Now I have to fight to get 5 euros back costs because of the 18 of the atrium, that's a lot!
I can not advise the seller, and thus the object that goes with it. THE M25 works very well, but it is disgust you bluetooth.
