I have been using these earphones for three months, and they have been troubling me ever since the first day. The voice is not as good as expected. The base is not sharp. It sometimes shows problems in connecting on the first go. It has to be tried for two times, at least. When the earphones are used with the CDLA voice output system, the base output become worse. The receiver of the earplugs is not as good as the receivers of the earphones of the same range. The color is so dull, and no color options are there.
Altogether, the buyer is on its own risk.
