Review title: Work perfectly with Blackberry 8830 World Edition
Product review: These headphones work perfectly with the Blackberry 8830. Stero comes in loud and clear and the mute button when a call comes in works well. You can clearly hear the call and the caller can hear you. For the price, try them, you can't go wrong. Don't bother buying a 3.5to 2.5 headphone adaptor, it won't work. Buy these stereo headphones.
