The first was sent back to Phillips after 15 days. Was not working, we could not talk. The second, a listener does not work after almost 2 months of use. Moreover, as in the first, the cable squirmed himself along its length and it is very painful.
In short, I do not recommend this product, especially since it is not a first prize, even if I agree, it's not too expensive either. But better worth putting a little more.
