Query: Don't buy this Item from Amazon.com

I bought this item based on all these reviews. Still waiting to see if I get the $30. off as promised from applying for the card. The headset did not work fully. Would not give ring tone, speaker crackled as if punctured, and that just the first 48 hours. Naturally, I went to Amazons return and exchange site.So Sorry, we don't exchange any Items you have purchased~~But Jabra will do it in 3 days; however you must pay to return it.I still believe in the product, just buy it somewhere with a honest defective return policy.
