I am satisfied with this Bluetooth kit, which fits well in price / quality installed on a modular CABERG DUKE headphones recharges quickly. Use with the iPhone 5 is correct but nothing with the command button, surely not SIRI alas. by the win against rolling is effective, we can listen to zik but the sound is average, do not dream either HP quality at this price. However deserves its 4 stars. recommended for those who do not want to ruin to answer calls by motorbike because communication is correct, using his GPS, but not great for music ...
