up vote 4 down vote favorite. I'm shopping for a new Bluetooth headset for my iPhone 4 and noticed that some headsets support the apt-X codec for CD-quality sound. Presumably this is better quality than plain old A2DP that I've been using so far.
ETHNONYM: Vaishya. The Vaisyas are the third-highest of the four varnas or categories into which Hindu society is traditionally divided, ranking above the Sudras. Vaisya includes a large number of distinct castes of similar ranking, traditionally traders, moneylenders, or farmers. They are entitled to wear a sacred thread.
The varnas have been known since a hymn in the Rigveda (the oldest surviving Indian text) that portrays the Brahman (priest), the Kshatriya (noble), the Vaishya (commoner), and the Shudra (servant) issued forth at creation from the mouth, arms, thighs, and feet of the primeval person (purusha).
